BACKGROUND Free muscle transfer for facial reanimation has become the standard of care in recent decades and is now the cornerstone intervention for dynamic smile reanimation. We sought to quantify smile excursion and quality-of-life (QOL) changes in our pediatric free gracilis recipients following reanimation. METHODS We quantified gracilis muscle(More)
OBJECTIVES To describe a procedure to permanently address platysmal synkinesis and hypertonicity and to report changes in quality of life associated with platysmectomy using the Facial Clinimetric Evaluation instrument. METHODS Chemodenervation significantly relieves platysmal synkinesis in almost all patients with significant face and neck synkinesis(More)
Functional recovery is typically poor after facial nerve transection and surgical repair. In rats, whisking amplitude remains greatly diminished after facial nerve regeneration, but can recover more completely if the whiskers are periodically mechanically stimulated during recovery. Here we present a robotic "whisk assist" system for mechanically driving(More)
INTRODUCTION Rodent whisking behavior is supported by the buccal and mandibular branches of the facial nerve, but a description of how these branches converge and contribute to whisker movement is lacking. METHODS Eight rats underwent isolated transection of either the buccal or mandibular branch and subsequent opposite branch transection. Whisking(More)
IMPORTANCE Recovery from facial nerve transection is typically poor, but daily mechanical stimulation of the face in rats has been reported to remarkably enhance functional recovery after facial nerve transection and suture repair. This phenomenon needs additional investigation because of its important clinical implications. OBJECTIVE To determine whether(More)
