[Intracranial reconstruction of the facial nerve in acoustic neurinoma surgery (author's transl)].

The authors have operated a consecutive series of 80 acoustic neurinomas. They were able to preserve the facial nerve in 53 patients. In thirteen cases an intracranial reconstruction of the nerve was performed : six times by direct anastomosis, in seven cases by grafting the nerve with the sural nerve. Details of the operative technique and the functional results are reported.
