ABSTRACT

The need to conserve the facial nerve function in the vestibular schwannomas surgery has become a priority in present time, for the sake of increasing the quality of life for these patients. Everyday we hear of more and more achievement reports of a total injury resection, with a functional conservation of the facial nerve. We present a retrospective study of 15 patients’ bearers of vestibular schwannomas, who were intervened by basal microsurgical approaches, with opening of CAI in 13 out of the 15 patients, being carried out in 70% of the procedures transurgery stimulation. The average tumoral size went close to large wounds 3.7 cm, with an index of total resection in six patients and subtotal above 90% in five cases; the anatomical conservation of the facial nerve was achieved in 84% of the patients, with facial nerve function worsening to some extent in six cases, and a partial recovery in some of these during the first subsequent year after the procedure. An analysis of the variables was carried out one with a higher influence in achieving a functional and anatomical conservation of the facial nerve in the management of this type of wound, stressing the use of the microsurgery, initial opening of the CAI with identification and control of the facial nerve through the use of stimulation and the use of approaches in the base of the skull, in the case of large wounds with petroclinoid extension.
