Tumor size was estimated from computerized tomography (CT) scans, and its influence on anatomical and functional preservation of the facial nerve was assessed. Six tumors (one invading the petrous bone, three medium and two large tumors) were not detected on CT scans. The translabyrinthine approach was used in seven instances (one small and six medium tumors) and the suboccipital transmeatal approach for 28 tumors (seven medium and 21 large tumors). Anatomical preservation of the facial nerve was achieved in 83% of operations for tumor removal, two of which were subtotal. A further two patients underwent subtotal removal, but the facial nerve was destroyed. Large tumors carried an increased risk of damage to the facial nerve, but even in this group the nerve was preserved anatomically intact in 70% of cases. Damage to the facial nerve occurred more frequently in patients with preoperative evidence of facial weakness; however, this factor did not appear to influence functional recovery of the facial nerve, provided that the nerve was intact at the end of the operation.<\/jats:p>\n<jats:p content-type=\"fine-print\">A simple grading system for facial nerve function is described. Only 76% of anatomically intact facial nerves showed any evidence of function 1 month after surgery. Postoperatively, facial function improved with time. At the latest review, 45% of these patients had normal facial function or mild facial weakness (Grades I and II).<\/jats:p>","DOI":"10.3171\/jns.1982.57.6.0739","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T13:59:57Z","timestamp":1241791197000},"page":"739-746","source":"Crossref","is-referenced-by-count":36,"title":["Facial nerve preservation during surgery for removal of acoustic nerve tumors"],"prefix":"10.3171","volume":"57","author":[{"given":"Richard H.","family":"Lye","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Dutton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard T.","family":"Ramsden","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph V.","family":"Occleshaw","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iain T.","family":"Ferguson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Facial Nerve Surgery.","first-page":"527","article-title":"Classification and standardised documentation of surgical results","author":"Adow","year":"1977"},{"key":"b2","series-title":"Intracranial Tumours.
