Abstract
- Purpose of Review: This systematic review investigates the recent literature and aims to determine the approach, efficacy, and timing of facial nerve decompression with or without grafting in temporal bone fractures with facial palsy.<br />Recent Findings: The surgical management of facial palsy is reserved for a small population of cases in which electrophysiologic tests indicate a poor likelihood of spontaneous recovery. The transmastoid (TM), middle cranial fossa (MCF), and translabyrinthine (TL) approaches to the facial nerve provide access to the entire intracranial and intratemporal segments of the facial nerve. In temporal bone (TB) related facial palsy, the peri-geniculate and labyrinthine portions of the facial nerve are most commonly affected by either direct trauma and/or subsequent edema. When hearing is still serviceable, the combined TM/MCF approach provides the best access to these regions. In the presence of severe sensorineural hearing loss (SNHL), the TL approach is the most appropriate for total facial nerve exploration (this can be done in conjunction with simultaneous cochlear implantation if the cochlear nerve has not been avulsed). Grade I to III House-Brackmann (HB) results can be anticipated in timely decompression of facial nerve injury caused by edema or intraneuronal hemorrhage. Grade III outcomes, with slight weakness and synkinesis, is the outcome to be expected from the use of interpositional grafts or primary neurorrhaphy. In addition to good eye care and the use of systemic steroids (if not contraindicated in the acute trauma setting), surgical decompression with or without grafting/neurorrhaphy may be offered to patients with appropriate electrophysiologic testing, physical examination findings, and radiologic localization of injury.<br />Summary: Surgery of the facial nerve remains an option for select patients. Here, we discuss the indications and results of treatment as well as the best surgical approach to facial nerve determined based on patient's hearing status and radiologic data. Controversy remains about whether timing of surgery (e.g., immediate vs. delayed intervention) impacts outcomes. However, no one with facial palsy due to a temporal bone fracture should be left with a complete facial paralysis.<br /> (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)
