The surgical approach was retrosigmoid\/ trasmeatal and the goal was total removal in one procedure with preservation of facial and cochlear nerves. Radical removal of lesion was attempted in 79 cases and it was possible in 77 patients. Subtotal tumor resection was planned in 2 cases. Facial nerve function (grades 1 to III, House and Brackman) was preseved in 90% and hearing in 58% of those with preoperative hearing. Three patients died due to postoperative complications. Early diagnosis of acoustic neurinomas is the most important factor in the prognosis and is one of the most important conquest of neurophysiology and modern neuroimaging. The management of these patients still present many controversial points. This article presents the diagnostic procedures used for acoustic neurinomas, the advantages and disadvantages of the different surgical approaches and the alternative management of these lesions.<\/jats:p>","DOI":"10.1590\/s0004-282x1997000300007","type":"journal-article","created":{"date-parts":[[2010,10,17]],"date-time":"2010-10-17T01:13:24Z","timestamp":1287278004000},"page":"393-402","source":"Crossref","is-referenced-by-count":8,"title":["Acoustic
