[Intrapretosal schwannomas of facial nerve].
The aim of this study was to determine the factors that are important to the diagnosis and treatment of facial neuroma. The most common tumors of the peripheral nerves are the neurinomas; about 50% of them are found in the head and neck region. Among them, the most frequent is the VIII nerve tumor, while the facial neuroma is extremely rare. Neuromas can be intracraneal, intratemporal and extratemporal. The last one has a higher frequency. We present our experience in the intrapetrosal facial neuromas; usually showing different presentation symptoms wich is a characteristic of them. Retrospective study that was carried out at a private tertiary referral center. 3 patients were referred from other centers for otological surgery. One of them had symptoms of chronic otitis media, the second one was diagnosed of a glomus tumor and the last one showed a facial palsy. All the patients were operated on and then the facial nerve was repaired. Two patients had an end to end anastomosis, and in the other one we managed to keep the integrity of the facial nerve. The Hous -Brackmann facial grading scale was used. Two patients had grade II and the other grade III in this scale in the long-term follow up.
