    Abstract:
    OBJECTIVE: Primary tumors of the facial nerve are rare, representing 1% of all intrapetrous lesions. We analyzed the management and surgical outcomes of 16 patients with multisegment facial neuromas treated at our institution during a 16-year period. STUDY DESIGN: A retrospective chart review. SETTING: Tertiary referral center. PATIENTS: All patients included in the study had surgical management of their facial neuroma. There were 9 women and 7 men. The mean age was 46 years, with a mean follow-up period of 3 years. INTERVENTION: Surgical excision (n = 15) or decompression (n = 1) of facial neuroma. MAIN OUTCOME MEASURES: Tumor location, presenting symptoms, hearing outcomes, and facial function. RESULTS: Thirteen (81%) patients had facial paresis as their presenting symptom. Unilateral hearing loss was present in 9 (56%) patients. Most tumors (n = 15) involved multiple segments of the facial nerve and ranged in size from 1.5 to 7 cm. Fifteen (94%) patients had the tumor completely excised, and 1 (6%) patient underwent needle decompression of the cystic component of the tumor. The geniculate ganglion was the most commonly involved (11 patients, 69%) segment of the nerve, followed by the labyrinthine and tympanic segments. Despite multiple types of reconstructive options used, the best recovery of facial function was a House-Brackmann Grade III in 12 patients. CONCLUSION: Treatment of facial neuromas depends on the extent of tumor, degree of facial paresis, and hearing function. We advocate complete resection of tumor when facial palsy exists. Patients with normal facial function and hearing may be advised on a more conservative treatment option such as radiologic observation, drainage of any cystic component of the tumor for histologic diagnosis, and/or bony decompression of the tumor.
