CHAPTER 19 Superomedial Pedicle Breast Reduction Using a Vertical Pattern

Introduction

Although the technique of vertical breast reduction was pioneered by Marchac13 and Lassus46 nearly three decades ago, it was popularized by Lejour7,8 in the 1990s and to the present day most notably by Hall-Findlay.9,10 The ability to utilize the vertical reduction skin pattern with a variety of pedicle options and to deliver a reliable and aesthetically pleasing breast shape is compelling support to have this operation in any plastic surgeon’s armamentarium. Part of the resistance to adopting this technique has been wound healing problems along the vertical scar and lower incisional puckering. Complications and need for revision are minimized by avoiding excessive cinching of the skin closure and by careful patient selection taking into account skin quality and estimated resection volume.

There has been an evolution throughout the senior author’s practice which has culminated in the current technique for vertical breast reduction. Early on, the majority of reductions were performed using the inferior pedicle and Wise pattern. The boxy postoperative shape and bottoming out of the breasts, led to dissatisfaction and interest in trying other techniques. After reviewing the experiences of Madeleine Lejour7,8 the notion of not relying on the skin envelope to shape the breast became an important concept in adapting the vertical technique to clinical practice. Multiple different pedicles were tried with the vertical skin pattern. First, the superior pedicle was used, and soon after abandoned in most cases due to difficulty folding large dense breasts that often resulted in significant drag on the areola. Second, the lateral pedicle was employed; however, this presented a limited opportunity for debulking the lateral aspect of the breast, the quadrant most often in need of debulking. The superomedial pedicle was the next choice and remains the first choice of pedicles when using the vertical technique (and even the Wise skin pattern). The ability to sculpt the pedicle and vary the lateral tissue resection affords great flexibility with this approach. In addition, utilizing a superomedial pedicle leaves the cleavage undisturbed and provides an attractive breast shape. There remain some instances where due to a patient’s anatomy, the superior pedicle is a better choice. These cases occur when there is minimal ptosis and superior migration of the nipple is a short distance. We have used the rule that if nipple elevation is less than 4 cm, a superior pedicle is chosen. We like the approach of Frank Lista who advocates using the superior pedicle if the existing nipple position is at or above the 6 o’clock mark on the keyhole.11

Patient Selection

The majority of women seeking consultation for breast reduction surgery are appropriate candidates. However, some may be declined surgery, not because of anticipated lack of symptom relief, but because they are at higher than acceptable risk for complications. The two main exclusion criteria for breast reduction surgery in our practice are obesity (body mass index, BMI > 35) and current smokers.1214 There are instances where patients with significant obesity are considered for surgery; however, these exceptions are decided on a case by case basis. We have a smoking policy for all elective surgery performed in our section. Patients are required to be smoke free for a minimum of 4 weeks preoperatively. We check a urine cotinine test on the day of surgery in patients known to be smokers to confirm compliance with our smoking policy. If the test is positive, the case is cancelled. This is communicated well in advance given the inconvenience to the patient and the operating room schedule when this occurs.

Initial Consultation

When the initial consultation is booked, women are mailed an information package to review prior to the visit. This includes a brochure and informed consent on breast reduction developed by the American Society of Plastic Surgeons. Women are provided with several website addresses to further explore breast reduction surgery. A shared medical appointment model is used for the initial consultation in the majority of our patients.15,16 This model provides ample time for women to interact with nursing staff, the surgeon, and other patients, and to watch a 12 minute video production, all of which greatly enhances the informed consent process. The video details the procedure of breast reduction and emphasis is placed on the fact that there is no guarantee of a specific requested cup size and that surgery is best done at a realistic long-term stable weight. The video also describes alternate skin incisions, pedicle versus free nipple graft techniques, and the surgical risks. Photographs of excellent, average, and poor results are presented as are complications, including nipple necrosis. The evidence of this surgery on decreasing breast cancer risk is also communicated. The outpatient nature of the surgery, drains, postoperative recovery, and time required off work is reviewed.

As part of the shared medical appointment, individual examinations are performed. This includes recording of the following measurements: sternal notch to nipple distance (SN-N), IMF to nipple distance (IMF-N), the proposed new location of the nipple which is the IMF transposed to the anterior breast skin in line with the breast meridian, the anticipated elevation of the nipple, the distance from the superior areolar border to the proposed new nipple position, the degree of ptosis, the skin envelope quality/elasticity, the presence of shoulder grooves, palpable breast masses, scars, axillary rolls, and any rashes. Estimations are made of the volume of each breast as well as the anticipated resection given the patient’s desired final cup size. There are multiple techniques to estimate resection volume including mathematical formulas and water displacement however it is in the opinion of the senior author that the ability to predict resection volume comes with experience.17,18

After the examinations are completed, a group discussion is held with the purpose of assisting each woman individually to decide the most optimal surgical approach. The patient is informed that with the vertical incision pattern, there is less scarring on the breast compared to the Wise pattern, but there may be a slightly greater risk for delayed healing and desire for scar revision, which is not likely covered by insurance. As a general guideline, patients with sternal notch to nipple distances less than 40 cm are candidates for one of the pedicle techniques (Fig. 19.1). In choosing the vertical pattern versus other patterns, we take into consideration the amount of resection as well as the patient’s skin envelope. Patients are informed that in resections over 1000 g, there is an increased risk of having a poor cosmetic result with the vertical technique and are thus advised to select the Wise pattern. However, should they have a strong preference for the vertical approach, they are counseled that this can be attempted with the flexibility of altering the plan intraoperatively to include a ‘J’ or a short ‘T’ conversion along the IMF. This part of the session generates many additional questions that help address the nuances of the surgical techniques and expectations for surgical outcomes.

As with all surgical decisions, they have to be customized to the patient. Our current algorithm is presented in Figure 19.1. In our practice, the vertical pattern and superomedial pedicle are used in 70% of all breast reduction cases. The following exceptions are necessary in select patients. The superior pedicle will be chosen if anticipated nipple–areola complex (NAC) elevation is small – less than 3–4 cm. In cases where there are pre-existing scars precluding the use of the superomedial pedicle, then usually an inferior pedicle is chosen with a Wise pattern. In patients with SN-N distances greater than 40 cm or with IMF-N distances greater than 20 cm, free nipple grafts are used with the Wise pattern. One caveat with using SN-N distance cutoffs: there are cases where the woman is willing to retain more volume than is typical. In this scenario, one can consider using a pedicle technique even with SN-N greater than 40 cm. If the patient requests to be as small as possible, then free nipple grafts may be necessary. In all breast reduction surgery, one must consider a woman’s expectations and her anatomy to arrive at the optimal choice.

Operative Technique

Part I: Preoperative markings

On the day of surgery, the following materials are needed to perform the markings: ruler, tape measure, keyhole pattern, and surgical skin marker (Fig. 19.2). The template we use is made from commonly available material in any operating room. It is made out of silicone sheeting (thickness 1.0 mm (0.04 inches)) or two sheets of foam tape. The areolar diameter is 42 mm and the vertical limbs are 5 cm. There are additional templated hash marks for the 3 and 9 o’clock positions along the keyhole.

There are seven key steps to focus on in the markings (Fig. 19.3): (1) breast meridian, (2) new nipple height, (3) vertical limbs, (4) keyhole pattern, (5) ghost patterns, (6) pedicle design, (7) recheck all markings, especially the pedicle for symmetry.

With the patient standing hands on hips and surgeon seated, the midline is drawn from the sternal notch to the umbilicus.

Key step #1: The breast meridian, the vertical representation of the central axis of the breast, is drawn from clavicle across the superior breast, inferior pole and across the ribcage (Fig. 19.3B). This line does not necessarily pass over the nipple. In patients with eccentric nipples, the breast meridian will not intersect with the nipple but may cross the areola.

Key step #2: Avoid using a standard SN-N length to set the new nipple position. The NAC should be placed at the level of the IMF. The IMF is transposed to the front of the breast as recommended by Gradinger,13 by positioning a flexible ruler along the IMF under the breast on one side and allowing the ruler to cross the midline on the anterior surface of the opposite breast (Fig. 19.3A). The IMF can thus be accurately translocated to the anterior breast surface. Potential pitfall: Although the senior author previously used the bimanual palpation technique to transpose the IMF, a technique that works nicely with the Wise pattern approach, this has a tendency to leave the planned position for the NAC too high on the newly created breast mound. A purposeful lowering of the NAC compared to Wise pattern markings must be made when using the vertical skin pattern approach.

To delineate the anatomic transition between the breast and axillary roll, the woman is asked to raise her arms above her head and the lateral breast boundary is marked (Fig. 19.4).

Key step #3: To delineate the vertical limbs of the keyhole pattern and thus the length of the medial and lateral flaps, the breast is rotated lateral and superior and the vertical axis of the meridian is transposed to the displaced medial breast tissue. In a similar fashion, the breast is rotated medial and superior, the meridian transposed, to delineate the lateral extent of skin resection (Fig. 19.3C). Surgeons new to this technique often find it difficult to master the tension used to rotate the breast in these maneuvers. Fahmy and Hemington-Gorse described a marking technique that some learners might find useful where the patient is marked on a level stretcher.19
