CHAPTER 26 Transblepharoplasty browlift

History

Since the initial description of the browlift by direct supraciliary forehead excision in 1964 by Castanares, several changes have allowed for its evolution: a more complete understanding of the role of the periorbital musculature and the advent of minimally invasive surgery and endoscopic techniques. The principal components of any surgical rejuvenation of the upper third of the face include orbital rim soft-tissue release, partial corrugator resection and frontalis modification, and lifting the brows to passively improve the upper eyelid aesthetics. These tenants have not changed but the approach to achieving them has evolved.

In 1982, Sokol and Sokol described the transpalpebral brow suspension through a blepharoplasty incision. They used interposing periosteal and orbicularis oculi flaps to elevate the brow without the need for a forehead incision. McCord and Doxanas also described a transpalpebral browpexy through a blepharoplasty incision in 1990. In 1996, Paul published his technique for the transblepharoplasty subperiosteal browlift. The periosteum of the superior orbital rim is incised lateral to the supraorbital neurovascular bundle extending to the subtemporalis fascial plane. The origin and insertion of the procerus are divided and the corrugator muscles are partially incised. In order to allow stabilization, a temporal incision is made for an oblique vector and lateral brow elevation and an anterior hairline incision made for vertical brow stabilization. Zarem et al. modified these techniques by elevating the undersurface of the orbicularis oculi and then securing it approximately one centimeter above the orbital rim. Niechajev again further modified this technique in 2002 by including orbicularis oculi muscle plication. These techniques were further advanced by the use of the endoscope. Ramirez described the similar approach with the addition of the endoscope.

It has been our practice since 1996 to perform fixation of the periosteum to the overlying orbicularis oculi. Since 1997, 281 cases have been performed in this manner. The indications initially included bald or high hairline patients but have since expanded to include patients with a thinning frontal/temporal hairline, with brow asymmetry, with mild to moderate non-central brow ptosis and as an adjunct to standard upper eyelid blepharoplasty. It can also be implemented in cases of concurrent or prior endoscopic browlifting to address recurrent trouble spots.

The advantages are the access through the upper blepharoplasty incision, technical ease, less bruising, and a shorter surgical time. In our opinion the results demonstrate an improvement in lateral brow or crow’s feet and the face to brow transition in cases combined with facelifting.

Anatomy

The transblepharoplasty browpexy focuses on the interface of two muscles: the orbicularis oculi and the frontalis. The orbicularis oculi is a sphincteric muscle involved in eyelid closure, both voluntary and blink. It has a concentric orientation of muscle fibers, which divide into the palpebral (pretarsal and preseptal) and orbital portions. The palpebral division is located just above the margin blending into the orbital portion of the orbicularis oculi, which in turn extends circumferentially to approximately 1.5 cm beyond the orbital rim.

The upper margin of the orbicularis oculi overlaps the frontalis muscle superiorly, the corrugator muscle, supratrochlear and supraorbital nerve medially and the anterior temporal fascia laterally.

Innervation to the forehead and supraorbital musculature is derived from the facial nerve (CN 7).

The frontalis muscle originates superiorly from the galea aponeurosis and attaches inferiorly onto the skin of the forehead. The temporal branch of the facial nerve innervates the frontalis muscle. The nerves travel in the areolar plane deep to the SMAS then cross the zygomatic arch and innervate the frontalis muscle via its inferior surface.

The temporal, zygomatic and buccal branches of the facial nerve innervate the orbicularis oculi on its deep surface. Sensibility to the forehead and brow is supplied by the ophthalmic division (V1) of the trigeminal nerve. The supratrochlear and supraorbital nerves arise from the trigeminal nerve and exit the skull via foramina or grooves at the supraorbital rim. After exiting the groove or foramen, the supraorbital nerve divides into the superficial and deep branches. The superficial supraorbital branches run over the surface of the frontalis muscle and supply sensibility to the lateral forehead, brow and anterior scalp with cross-over innervation from the zygomatic temporal branches which originate from the lateral forehead. The deep supraorbital division travels in a plane which is deep to the frontalis muscle to provide sensibility to the frontoparietal scalp.

The supratrochlear nerve branches pass through the corrugator supercilii muscle and supply sensibility to the central forehead.

Complications

The most frequent complications are transient contour abnormalities and dimpling at sites of suture placement and lower forehead, brow numbness. Both of these complications are transient. Less common complications include recurrent brow ptosis, asymmetry and hematoma.
