Abstract

The aim of this paper is to review the specific problems of the microsurgical management of the acoustic neuromas not suitable for radiosurgical treatment , that is measuring more than 8 cc in volume or 2.5 cm in maximum diameter in the cerebelopontine angle. A total of 18 lesions have been included with a mean volume of 27.4 cc, representing a lesion measuring 3.8 cm in its three main diameters. The mean follow-up has been 48.7 months. There has been no mortality. All lesions were completely excised without recurrences. The anatomic conservation of the facial nerve was achieved in the 66.7% of the cases but the functional recovery (House-Brackmann grades I-II) was reached only in the 27.8%, without any grade I case. As permanent deficit all patients had postoperative cophosis, two had trigeminal hyposthesia with corneal anesthesia and one had a cerebellar deficit. The main conclussion is that the microsurgical radical resection of large acoustic neuromas not suitable for radiosurgical treatment is followed by a high postoperative morbidity mainly related with the facial nerve lesion. Therefore, it seems rationale to design specific strategies directed to reduce and alleviate these permanent deficits.
