Aesthetic Alteration of Prominent Ears

Evaluation and Surgery

Aside from the excision of auricular tags and the repair of traumatically clefted ear lobes, the prominent ear is the most commonly treated external ear deformity. Approximately 5% of the Caucasian population has protruding ears, thereby making this the most frequent congenital anomaly of the external ear. Otoplasty is a common aesthetic operation that is carried out among children and adolescents to address this issue. There is a wide variation with regard to what is considered normal for ear size, prominence, and shape (Fig. 39-1). An “outstanding” ear is said to be present when the distance of the helical rim from the temporomastoid surface of the skull is excessive. As a general rule, a measurement of more than 16 to 21 mm is said to result in a prominent ear (Fig. 39-2). The average ear is 6.5 cm long and 3.5 cm wide, but significant variations are considered acceptable. After the completion of normal ear growth and with ongoing age, the external ear changes in that the elongation of the soft tissue covering and the earlobe is to be expected. Provided that the ear has a morphology that is in balance with the other facial features and that there is reasonable symmetry from one ear to the other, these variations are considered to be in an acceptable aesthetic range. However, when ear shape, size, and proportion are perceived as distracting to the casual observer at conversational distance, the ears may become a source of ridicule and personal anguish. Affected children are frequently stigmatized by their peers and commonly ask their parents if a solution for their visible abnormal ear shape can be found. In these circumstances, the surgical correction of the prominent ear is likely to have a beneficial effect on the person’s self-esteem and body image.

A failure of scaphal folding (i.e., limited antihelical fold) as well as conchal hypertrophy (i.e., increased depth of the conchal wall), prominent lobules (i.e., protruding ear lobes); and anterolateral rotation of the concha (i.e., cupping of the ear) frequently create prominence of the external ear.5,13,14,30,52,57,67 Noticeable ear protrusion often results from a combination of these deformities. An accurate assessment of the ear dysmorphology is essential to the achievement of an unobtrusive look through surgery. Adjusting the scaphal (antihelical) folding with sutures, reducing the conchal wall depth via conchal excision and conchal mastoid sutures, and performing lobe set-back with sutures and excision are typical components of the surgical correction that is undertaken to achieve a favorable result.3,4,6,11,26,50,55,60,70,72

Overemphasis on the surgical creation of an antihelical fold without paying proper attention to conchal hypertrophy often results in an oversharpened antihelix and a buried helical rim (i.e., “telephone ear”). Some surgeons advocate cartilage-cutting (i.e., scoring) procedures rather than sutures to achieve a preferred antihelical fold.11 These cartilage-scoring techniques generally require dissection of the soft tissues off of the anterior surface of the cartilage. This can result in hematoma, skin necrosis, and chondritis, which may result in irreversible cartilage or external ear irregularities. Surgical correction of the outstanding ear should in general be uncomplicated and result in reliable, long-lasting, favorable aesthetics with minimal downtime for the patient and minimal chance of relapse.

When considering the ideal timing for external ear surgery, it is important to balance what we know about ear and facial growth, psychosocial development, and the ability of the child to comply with the necessary routines after surgery.1,20,21,39 The goals of otoplasty for the management of congenitally prominent ears, as outlined by McDowell, remain universal despite a multitude of etiologies and suggested surgical techniques.42 According to McDowell, the surgical goals should include the following:

Historic Perspective

Dieffenbach is credited with reporting the first otoplasty in the medical literature in 1845.15 This was performed to reconstruct a traumatically deformed ear. The ear surgery consisted of excising skin from the postauricular sulcus and suturing the conchal cartilage to the mastoid periosteum (i.e., conchal–mastoid suturing). In 1881, Ely was the first surgeon to report a procedure for the aesthetic correction of a congenitally prominent ear.19 He resected both the skin and the conchal cartilage, but he did so as a two-stage procedure (i.e., one ear at a time).56 Moristin further developed these skin-excision and cartilage-resection otoplasty techniques.44 In 1910, Luckett realized that a prominent ear frequently resulted from the congenital failure to form an antihelical fold.38 He was the first to describe setting the ear back via the removal of postauricular skin and by simultaneously completing an incision through the length of the ear cartilage in an attempt to create the deficient antihelical fold; he also placed sutures to hold the new fold in place. In 1960, Stenstrom used the known principles of cartilage biology as described by Gibson and Davis in 1958 to propose the scoring and abrading the anterior cartilage surface to weaken it and thereby create an antihelical fold.61,62,25 In 1963, Mustarde introduced the placement of mattress sutures in the posterior cartilage surface of the ear as a technique for the creation of a new antihelical fold.4648

In 1967, Kaye combined the anterior scoring technique of Stenstrom and the posterior suture placement technique of Mustarde to limit the relapse that surgeons complained about when using either technique alone; he also advocated the use of nonresorbable suture.32 In 1968, Furnas reintroduced the technique of conchal–mastoid suturing to set back the prominent conchal bowl.2224 He also advocated cleaning out the soft tissue in the postauricular groove (i.e., postauricular muscle and fibrofatty tissue) so that the concha could be rotated in a sagittal plane from posterior to anterior (clockwise rotation) before anchoring it to the mastoid fascia (conchal–mastoid sutures) with nonresorbable sutures. In 1969, Webster advocated paying special attention to the prominent earlobe to achieve a successful otoplasty.69 He noted that the “tail” of the helix could be repositioned with suture to change the lobe’s orientation. In 1972, Elliott combined and refined all of the previously described techniques to manage, the deep conchal wall, the limited antihelical fold, and the abnormal earlobe that were frequently seen in the prominent ear.18 He advocated the use of elliptical partial conchal wall excision when conchal–mastoid suturing alone was felt to be insufficient to correct the ear prominence. He used an anterior incision placed within the “shadow zone” of the conchal margin when conchal resection was required. Bauer advocated the use of the Elliott anterior conchal cartilage excision but preferred to also excise anterior skin to avoid postoperative skin folding or bunching.4

Embryology and Anatomy

Embryologically, the ear arises from six hillocks of the first and second branchial arches during the second to fourth month of gestation. Hillocks 1 through 3, from the first arch, form the anteromedial aspects of the auricle (i.e., the tragus, the helical crus, and the helix, respectively). Hillocks 4 through 6, from the second arch, develop into the posterolateral aspects of the ear (i.e., the antihelix and the antitragus, respectively).34,35 During the third month of gestation, protrusion of the auricle increases. By the end of the sixth month, the helical margin curves, the antihelix forms its folds, and the antihelical crura appear at the superior aspect of the forming external ear. Congenital ear deformities result from the disruption of one or more of the auricular hillocks during embryogenesis. Any deforming forces to the side of the head of the fetus may also alter the shape of the external ear.

The ear is supplied by branches from the superficial temporal artery anteriorly and the posterior auricular and occipital arteries posteriorly. The superficial temporal, posterior auricular, and retromandibular veins provide venous drainage. The lymphatic drainage of the anterior three hillocks is mainly to the anterior triangle of the neck, whereas the posterior three hillocks ultimately drain into the posterior triangle of the neck. Lastly, the ear is supplied by the great auricular nerve on its lower lateral and inferior cranial surfaces, by the lesser occipital nerve on its superior cranial surface, and by the auriculotemporal nerve on its superior lateral surface as well as the anterior superior surface of the external acoustic meatus. The Arnold nerve, which is an auricular branch of the vagus nerve, supplies the posterior inferior external auditory canal and meatus as well as the inferior conchal bowl.34,35

The most frequently seen deformity or malformation of the external ear arises from the failure of the antihelix to fold. The conchoscaphal angle widens and results in a flat superior crus, antihelical body, and inferior crus. The helical roll (i.e., the antihelical fold) may be absent altogether or only partially formed, with a wide variation of deformity. Conchal widening (i.e., the presence of a deep conchal bowl) may also occur either as an isolated deformity or in conjunction with antihelical fold deformities. These congenital abnormalities are usually bilateral and often asymmetric, and they frequently demonstrate a familial pattern.

Bauer pointed out that the external ear may be thought of as consisting of a three-tiered cartilaginous framework with tightly adherent skin on the anterior surface and loosely applied skin on the posterior surface.4 The three tiers of sculpted cartilage form are the helical–lobular complex, the antihelical–antitragal complex, and the conchal complex. Key anatomic (aesthetic) landmarks of the normal ear include the scapha, the concha, the helix, the antihelix, the tragus, and the lobule (see Figs. 39-1 and 39-2).

Timing of Surgery

Auricular deformations are best suited for ear molding correction techniques. Molding therapy is preferably carried out during the first few days of life, as described later in this chapter. In general, the surgical correction of a malformation of the external ear is planned with an appreciation of normal ear maturation. As a result of differing interpretations of ear growth and the effect of an operation on residual growth of the auricle, opinions vary with regard to the preferred timing of definitive external ear reconstruction.

In a study by Farkas, two anthropometric surface measurements, ear width and ear length, were taken directly from the ears of normal subjects with the use of an anthropometric sliding caliper.20,21 At the age of 1 year, ear width is highly developed in both sexes (mean, 93.5%), and it is mostly completed at the age of 5 years (mean, 97%). The width of the ear reaches its full mature size in boys at the age of 7 years and in girls at the age of 6 years. At 1 year of age, the length of the ear has already attained 75% of its eventual adult size. By 5 years of age, 87% of its eventual development is observed. Ear length achieves its full adult size in 13-year-old boys and 12-year-old girls. Adamson and colleagues reviewed the growth patterns of the external ear and concluded that the ear reaches 85% of its overall adult size by the age of 3 years and that little change in ear width or the distance of the ear from the scalp occurs after 10 years of age.1 The authors concluded that, for all practical purposes, the normal ear is almost fully developed by the age of 6 years.

Although children notice differences in each other beginning very early in life, they are rarely self-conscious about differences in ear protrusion before 5 years of age.39 From this point on, however, social interactions with peers frequently elicit negative comments that can affect self-esteem and body image. The correction of external ear deformities before this age is possible, but the postoperative course may be compromised if the ear bandage is removed early by the uncooperative child or with disruption of the repair by pulling on the ears after the bandage is removed. Consideration is given to setting back the protruding ears as early as 3 years of age, although many children display improved cooperation and parents are more confident in their decision when children are between the ages of 5 and 6 years.

Aesthetic Objectives

It is recognized that there are wide variations with regard to ear proportions, projection, and position among individuals. When feasible, the surgically reconstructed (previously protruding) ear should be of ideal size and shape and have a good relationship with the other facial features and the contralateral ear. Loose guidelines for the assessment of preferred ear shape and position have been summarized by Tolleth.67

Ear Protrusion

Although the spectrum of protrusion of the helical rim from the scalp varies widely, a measurement of 1.5 to 2.0 cm is aesthetically acceptable.2

Patient and family satisfaction should be anticipated if the reconstructed ears are no longer a facial feature that draws attention when viewed at conversational distance by the casual observer. Sharp angles, unnatural contours, overcorrection and “eye-catching” asymmetry from ear to ear are not ideal. In the operating room, the surgeon should view the reconstructed ear from several feet of distance in frontal and profile views and from the rear. From the rear, the helical contour should form a relatively straight line; this will indicate that the antihelical fold (the upper third), the conchal depth (the middle third), and the lobe (the lower third) are in sync. From the front, the helical rim above and the lobe below should be seen to an extent just beyond the antihelix without any cupping of the upper and lower thirds of the ear. In profile, the contours should be gentle and the folds rounded.

Surgical Principles

A reconstructed prominent ear should be reasonably symmetrical with its counterpart and without a sharply angulated antihelical fold. If the upper third of the ear protrudes as a result of an absent or weak antihelical fold, then the fold should be improved (i.e., Mustarde and superior helix–mastoid stitches). If the middle third of the ear is too prominent (i.e., outstanding and away from the side of the head), then the concha must be recessed (i.e., conchal wall excision and conchal–-mastoid stitches) and the antihelical fold improved (i.e., Mustarde stitches). In the lower third of the ear, if the lobule protrudes, the surgeon must resect or reposition the cartilaginous tail, excise the retrolobular skin, or both.

Historically, the creation of an antihelical fold was carried out by techniques that involved either scoring or abrasion of the cartilage to control the direction and extent of folding.16,25,28 Later, suture techniques (i.e., Mustarde sutures) were added to reshape the cartilage. Many surgeons combine these methods. Interestingly, some “cartilage scorers” recommend partial-thickness scoring, whereas others score the full thickness of the cartilage.11 This author prefers to avoid scoring the cartilaginous surface all together, because this requires separation of the anterior skin from the cartilage surface with increased risk of hematoma, flap necrosis, and visible sharp edges on the anterior (cartilage) surfaces. The careful placement of Mustarde mattress sutures in a gentle curve will form a smooth antihelical fold. The Mustarde sutures are placed along the posterior surface of the cartilage as needed in the upper, middle, and lower thirds to accomplish aesthetic antihelical folding.4648

Conchal hypertrophy is a frequent component of the ear deformity. The correction of this aspect is usually accomplished through a combination of techniques, including the following: 1) the repositioning of the concha into the surgically “cleaned out” mastoid recess; 2) conchal set-back with conchal–mastoid sutures; and 3) conchal reduction through direct elliptical cartilage excision. If the anterior approach is selected for conchal wall resection, an incision (scar) must be placed on the anterior surface, but the folding of redundant skin is limited.4 If a posterior approach is used, there is a risk that the redundant anterior skin that is left behind may not shrink sufficiently and thus result in a visible fold in the conchal floor. Some surgeons believe that a redundant anterior skin fold may be more noticeable than a “fine” anterior conchal scar. This author prefers to excise conchal cartilage with the use of a posterior approach. The anterior skin is then released from the residual conchal floor cartilage to avoid bunching, as discussed later in this chapter.

To review, the ear set-back procedure will generally require the resection of conchal (wall) cartilage, the cleaning out of excess soft tissues in the retroauricular sulcus, and three rows of deep sutures. These three rows of sutures include the following: 1) Mustarde horizontal mattress sutures to create an antihelical fold; 2) conchal sutures for reconstructing after elliptical (conchal wall) resection; and 3) Furnas-type sutures, including placement in the conchal–mastoid region and the superior helix–mastoid region. Non-resorbable sutures should be used to limit relapse (4-0 Mersilene versus 4-0 clear nylon).

Surgical Technique (Figs. 39-3 through 39-9)

The intraoperative draping of the patient within the sterile field should provide visualization of both ears and the entire forehead, face, and neck as well as the ability to safely turn the patient’s head from side to side. An orotracheal tube with a natural curve at the level of the lower lip is used and secured to the skin of the chin with a minimal amount of tape (e.g., an Oral RAE endotracheal tube). Ophthalmic eye ointment and eye protectors (corneal shields) are placed below the eyelids to limit corneal injury and to prevent the need for tape or dressing material on the face. The patient’s head is placed on the Mayfield horseshoe head ring in the neutral neck position. The Mayfield provides stability and adequate exposure and allows for the turning of the head without disrupting the surgical field. The majority of the hair is wrapped in a sterile towel, and prophylactic intravenous antibiotics are given. A mouth pack is placed to limit saliva contamination of the surgical field.

The ears are marked on the anterior surface for the creation of a new or improved antihelical fold and on the posterior surface for an elliptical skin excision. Lidocaine (Xylocaine) 1% with 1 : 100,000 epinephrine is injected into the postauricular skin fold.

The postauricular incisions (i.e., elliptical skin excision) are completed with a scalpel (see Fig. 39-3). All soft tissue down to the posterior surface of the cartilage is removed. The postauricular medial and lateral skin flaps are elevated (see Fig. 39-4). The resection and removal of postauricular muscle and fibrofatty tissue that is between the conchal cartilage and the mastoid fascia is completed. This allows the concha to rest in a deep pocket so that the bending of the cartilage over a soft-tissue mound does not occur when tying conchal–mastoid sutures (Fig. 39-6A).

When scaphal folding is needed to improve the antihelical fold, the placement of postauricular horizontal mattress (Mustarde-type) sutures is carried out (see Figs. 39-5 and 39-6). Before the creation of the improved antihelical fold, the posterior cartilaginous surface is cleaned of all soft tissue. The Mustarde sutures are placed in a radial fashion to form a curved scaphal fold that extends from the superior crus down to the lobule. Antihelical reconstruction usually requires three to five Mustarde sutures to achieve a smooth roll. Each suture is tested for its effectiveness after it is placed, but none are tied until all are in position. If the position of the superior helix remains protruded, one or two additional superior helix–mastoid sutures can be placed to further accomplish the ear set-back.

A conchal set-back with sutures (conchal–mastoid sutures) is useful but generally inadequate for the management of even moderate degrees of conchal hypertrophy. Partial conchal wall resection is generally indicated (see Figs. 39-7 through 39-9). This author prefers to complete the resection through a posterior approach. An ellipse of the conchal wall that extends superiorly and inferiorly is excised to allow the bowl to reposition itself without a cartilaginous “dog ear” (i.e., puckering). If only minor degrees of conchal prominence exist, management just with the placement of conchal–mastoid sutures may be possible.

The position of the lobule can be further managed by the setting back of the tail of the helix. The helical tail is exposed on its posterior surface. The tail is sutured back to the concha or the mastoid fascia. Each placed suture is tested to determine if the desired position of the lobule will be achieved. In some patients, it is useful to excise cartilage at the lobule to achieve adequate positioning. In others, the excision of a postauricular wedge of skin is helpful.

Otoplasty for Prominent Ears: Step-by-Step Approach

Conchal Wall Resection for Set-Back (see Figs. 39-7 and 39-8)

• The planned elliptical excision of the conchal wall (superior to inferior) is marked out with a surgical pen or methylene blue on the posterior surface of the cartilage.

• The conchal excision should include a portion of the conchal wall. The full thickness of the ellipse of concha for excision is incised with a scalpel (no. 15 blade) but without perforation through the anterior skin.

• With the use of a Cottle elevator, the incised ellipse of cartilage is freed from the anterior ear skin and then removed.

• The anterior ear skin is further elevated off of the residual concha floor toward the ear canal. This will limit bunching of the skin during the healing phase after the conchal wall edges are reapproximated with suture.

• The edges of the cut conchal wall will be sutured together with 4-0 Vicryl to limit overlap. Wait to suture the edges together until the Mustarde sutures are placed and tied.

Deepening or Creation of the Antihelical Fold (see Figs. 39-5 and 39-6)

Placement of Conchal–Mastoid Sutures to Further the Set-Back of the Middle Third of the Ear (see Fig. 39-9)

Placement of Dressing (Fig. 39-10)

Postoperative Care

• After the ear dressing is removed, the patient is encouraged to shower and shampoo the hair and to wash the external ears, face, and neck one or two times daily. (Overly hot water should be avoided, because the ears will have diminished sensation.)

• The ears are dabbed dry after washing. (Excess rubbing of the ears should be avoided.)

• Ear protection is used when sleeping for 2 to 3 months to prevent accidental anterior folding of the external ears. A skier’s ear warmer or a tennis sweatband may be used for this purpose.

• No vigorous sports activities are allowed for 4 to 6 weeks.

• No strong sun (ultraviolet) exposure to the ears is allowed for approximately 3 months.

• When the patient has returned to more regular physical or sports activities after 4 to 6 weeks, additional precautions are encouraged, depending on type of sport activity (e.g., wrestling, basketball), during the initial 3 months after surgery.

Assessment of Results

Although prominent ears do not have any physiologic disadvantages, they play an important role in social life. Prominent ears often provoke teasing by others, especially by children; they can lead to emotional stress with a decline in the patient’s health-related quality of life; they may negatively affect school or job performance; and they may result in social avoidance and a loss of self-confidence (Figs. 39-11 through Fig. 39-27). Today, health-related quality of life is considered by many to be the most important parameter for the evaluation of aesthetic procedures such as the correction of protruding ears.7,64

In a recent study by Braun and colleagues, a consecutive series of patients (N = 84) who underwent otoplasty (suture technique) were given a health-related quality-of-life survey.6 The survey used was either the Glasgow Children’s Benefit Inventory (N = 41; 73.8% of study group) or the Glasgow Benefit Inventory (N = 21; 33.9% of study group). Both of these quality-of-life surveys have been validated for measuring the effect of plastic (aesthetic) operations on health-related quality of life. Sixty-two patients (73.8%) returned a valid questionnaire for analysis. For the study group, the main reasons for carrying out the ear set-back operations as reported by the patient and the family included teasing (42.6%); aesthetic impairment (39.3%); and reduced self-confidence (23%). The results of the study indicate that 100% of the adults were satisfied with their aesthetic results and that 90.5% would again decide in favor of the operation. Ninety-five percent of the parents of the children and 95.1% of the children themselves were satisfied with the aesthetic results. Ninety-seven percent of the parents and 92.7% of the children then also stated that they would again decide in favor of the operation. The authors also speculated that an individual’s reluctance to participate in certain social activities, if caused by reduced self-confidence as a result of the protruding ears, was more likely to remain constant with increased age. In other words, adults that had lived through the social ridicule of prominent ears for many years were more likely to retain reduced self-confidence even after successful ear set-back.

Complications and Suboptimal Aesthetic Results

Although the majority of patients state that they are satisfied with their otoplasty results and say that they would undergo such procedures again, complications and suboptimal results will always occur in a minority of cases.10,17,31,37,53,54,63

Failure (Relapse) of Scaphal (Upper Helix) Folding

In some patients, the created antihelical fold will open (relapse) with recurrence of the prominent ear appearance. This may occur for one of several reasons. If a Mustarde stitch becomes inflamed or infected, it may loosen, which results in the unfolding of the helix. In other situations, an uncooperative child may pull on the ears, thereby causing shearing of the sutures with a recurrence of ear prominence. For others, the sutures may not have a sufficient “bite” into the cartilage and thus not withstand the recoil forces. In this author’s experience, the use of non-resorbable (4-0 Mersilene or 4-0 clear nylon) suture is an important aspect for the limiting of relapse tendency.

In some patients, despite the placement of Mustarde stitches, the upper helix still protrudes. If residual protrusion of the upper third of the helix is observed early after surgery, it is most likely an intraoperative technical error rather than cartilage relapse. To prevent this problem during operation, rather than overtightening the Mustarde stitches, it is best to place a superior helix–mastoid suture.

Non-Surgical Correction of Prominent Ears in the Newborn

Although the idea of “binding” the external ears in an attempt to correct abnormalities is not a new one, Matsuo and colleagues can be credited with examining the efficacy of doing so in newborns.40 Byrd and colleagues convincingly demonstrated that there are particular auricular deformities in the newborn that are amenable to molding back toward normal.9 In their publication, the types of deformities that can be most effectively treated and details concerning methods of molding are discussed. Auricular deformations are characterized by a misshapen but fully developed pinna.65,66 Ear molding techniques are best suited for deformations rather than malformations.8,12,29,36,41,43,45,59,68,71 Interestingly, approximately one third of the ear deformations that are present at the time of birth self-correct during the first week of life. The patterns of deformation that are frequently seen include the following: prominent/cupped ears; lidded/lopped ears; Stahl (or Spock) ears; helical rim deformities (with an absent or deficient rim); and conchal crus deformities.49,51,58 Byrd and colleagues found that birth deformations of the auricle more often than not involve the upper third of the ear, with incomplete formation of the superior limb of the triangular fossa being a frequent finding. This leads to a helical rim scapha deformation. The authors stressed the importance of accomplishing three key molding forces to correct the majority of these ear deformations in newborns:

The authors described good to excellent results in 90% of the newborns whose external ear deformities were treated in this way. Complications were seen in only approximately 5% of patients and were mostly characterized as localized skin excoriations. The authors recommend withholding ear-molding therapy until the end of the first week to identify those infants whose ears spontaneously self-correct soon after birth. It is believed by most that, for treatment to be effective, it should be instituted by the second or (at most) third week of life. Only approximately half of the infants treated by Byrd and colleagues after 3 weeks of age had good outcomes. The reason for this is believed to be related to the level of hyaluronic acid, which is an important component of ear cartilage.27 Hyaluronic acid is increased by estrogen and believed to be responsible for the malleable nature of the neonatal ear. The circulating estrogen levels are known to decrease rapidly to levels that are similar to those of older children by 6 weeks of age.33 It is also known that, with breast-feeding, the maternal transfer of estrogen extends the time frame of higher hyaluronic acid levels, which likely explains the variations in the effectiveness of ear molding in some children; this may also leave the ears prone to relapse after molding treatment is stopped unless the result is maintained.

Patient Education Materials

Otoplasty (Reshaping of the Ears) Surgery

Although a wide variation in the shape and size of the ears naturally occurs from person to person, ears that stick out make individuals easy targets for teasing and ridicule. For most individuals, after this occurs, the sooner this problem is corrected, the better. Otoplasty is the name of the surgical procedure that is carried out to diminish ear projection or to change the appearance of the ears. It may be carried out as early as the ears approach their adult size (i.e., around the age of 3 to 5 years) or at any time thereafter. Each individual who is seeking otoplasty has unique concerns. It is important to fully discuss your expectations with your surgeon before surgery.

In general, the technical aspects of the otoplasty procedure include an incision that is made behind each ear to provide access to the ear cartilage. The cartilage of the ear is then reshaped to create improved curvature and position. The procedure is carried out on an outpatient basis with the patient under anesthesia in the operating room. With the ears reshaped and set back, a bandage is used to secure the new ear position and to limit swelling. The bandage generally remains in place for 5 days. After this, return to school or work is rapid. An extra level of care of the ears is required during the initial 4 to 6 weeks of healing.

Instructions for Otoplasty Surgery

The purpose of these instructions is to help you prepare for and then recover from otoplasty with as little discomfort and inconvenience as possible.
