[Preservation of hearing in surgery of acoustic neuroma].
Between 1981 and 1984, 44 patients underwent acoustic neuroma removal by a posterior cranial fossa approach in an attempt to preserve hearing. 7 tumors were small (less than 20 mm), 28 were medium (20 to 40 mm) and 9 large (greater than 40 mm). Of these 44 patients, 4 had normal hearing preoperatively, 15 had serviceable hearing, 10 poor hearing and 15 no hearing. Postoperative hearing was pres...

متن کاملHearing preservation surgery in acoustic neuroma: long-term results
Long-term hearing was examined in 200 patients operated on during 1976-2000 with removal of acoustic neuroma with a retrosigmoid approach and hearing preservation technique. Ninety-four cases preserved hearing, and 91 cases were followed-up for at least 6 years (range 6 to 21 years). Hearing was measured with the PTA 0.5 KHz to 4 KHz and the SDS, and followed the guidelines of the American Acad...
متن کاملHearing preservation surgery in acoustic neuroma. Slow progress and new strategies
Quality and rate of preserved hearing are crucial to make hearing preservation surgery a viable treatment. A long-term experience with hearing preservation surgery, with tumour size and hearing as admission criteria, was evaluated to assess which size and hearing allowed a high rate of success. The hearing outcome in relation to size of tumour and pre-operative hearing was retrospectively revie...
متن کاملHearing preservation in acoustic neuroma resection: Analysis of petrous bone measurement and intraoperative application
BACKGROUND There is an increased risk for labyrinthine injury for the resection of acoustic neuromas (AN) on the suboccipital, retrosigmoid approach. Prognostic factors should be analyzed for the postoperative hearing function. METHODS We examined 51 patients with ANs using preoperative intact hearing function. Audiological data were obtained by pure tone audiogram (PTA) and speech audiogram....
