Abstract | BACKGROUND AND PURPOSE: METHODS: Seven cases (four men and three women) of intracranial facial nerve schwannomas were retrospectively studied. RESULTS: Before treatment, we found deafness in six cases (two sudden and four progressive), a facial palsy in five cases (three sudden and two progressive). Five patients had deafness and facial palsy. One patient had only headache. Three schwannomas were supra and intra-petrous, two in the cerebello-pontine angle, and two were plurifocal (petrous bone, internal auditive canal and cerebellopontine angle). Six patients were operated on with an oto- neurosurgical procedure. After treatment, facial palsy always worsened (requesting secondary hypoglosso-facial anastomosis in cinq cases). Only one case of transmission deafness improved after ossiculoplasty. One patient is still under clinical and radiological observation. CONCLUSION: Diagnosis is difficult and made operatively in half of patients. A large tumor requires surgery, but surveillance can be a good option for a small one, considering the risk of postoperative facial palsy.
