An intact Bell's phenomenon on the patient's right protects the cornea despite inadequate lid closure. As with Bell's palsy, sufficient time must be given to allow spontaneous return of function before contemplating reanimation procedures. The gracilis is exposed and an adequate length is marked out centered on the pedicle.

The surgical anatomy and the number of fascicles of the ovine sural nerve were similar of those reported in humans. Lid laxity and ectropion are most frequently treated with medial and or lateral tarsorrhaphy30 or lid-tightening procedures.31 However, in our experience, use of a tendon sling for the lower eyelid32 in combination with a gold weight for the upper-lid produces the most consistent correction.

It is a distinct advantage to be able to adjust the vector of pull without being constrained by a muscle origin or a pedicle as can happen with local muscle flaps. Microsurgical transfer for facial reanimation. It was deep, extending posterior to the facial nerve in 6 specimens. The temporal branch has as many as 4 to 7 rami, with interconnection among them. Reconstruction of the flaccid cheek and sagging, adynamic commissure can either utilize static or dynamic procedures. The facial nerve has five main branches, although the anatomy may vary somewhat from individual to individual. The branches are, from top to bottom: frontal (or temporal), zygomatic, buccal, marginal mandibular and cervical. Each of these branches provides input to a group of facial expression muscles. Recovery The muscle is then attached to the superficial muscular aponeurotic system and zygomatic periosteum along the vector of pull, applying resting tension onto the commissure and creating a normal-appearing nasolabial fold (Fig. An official website of the United States government.
