Early temporalis muscle transposition for the management of facial paralysis

Temporalis muscle transposition is a reliable surgical technique for the reanimation of patients with long‐standing facial paralysis. It is often employed when facial nerve reinnervation via crossover or cable grafting is not possible. Temporalis muscle transposition can also be used for the immediate treatment of complete facial paralysis due to insults leaving the facial nerve anatomically intact but requiring a prolonged recovery time (more than 1 year). Because temporalis muscle transposition does not interfere with neuronal regeneration, it may be employed early in the management of complete facial paralysis when recovery is predicted to be extended and incomplete. The authors report their experience with early temporalis muscle transposition in the management of facial paralysis in 56 patients with an anatomically intact facial nerve. More than 90% of these patients achieved improved symmetry at rest as well as purposeful movement at the corner of the mouth. In the last 30 patients, the temporoparietal fascial flap was simultaneously harvested and successfully used to obliterate the donor site defect. In conjunction with the immediate implantation of a gold weight in the ipsilateral upper eyelid, this approach to the early management of facial paralysis helps reduce the period of facial disability from years to weeks in a select group of patients.
