Title: Hearing preservation in conservation surgery for vestibular schwannoma. Author: Holsinger FC, Coker NJ, Jenkins HA. Journal: Am J Otol; 2000 Sep; 21(5):695-700. PubMed ID: 10993461. Abstract: OBJECTIVE: To evaluate preservation of hearing in the resection of vestibular schwannomas. STUDY DESIGN: A retrospective case review. SETTING: Tertiary-care medical center. PATIENTS: Forty-seven patients (25 men, 22 women) were studied; mean age was 46 years, mean tumor diameter 9.8 mm (range 3-30 mm.) INTERVENTIONS: All patients underwent resection of vestibular schwannomas by the middle cranial fossa (MCF) or the retrosigmoid (RS) approach. MAIN OUTCOME MEASURES: Hearing preservation was classified by the criteria outlined by the American Academy of Otolaryngology-Head Neck Surgery. Hearing was assessed preoperatively and postoperatively at 1 month and 1 year. Facial function was graded according to the House-Brackmann scale. Minimum follow-up was 18 months. RESULTS: Hearing was preserved in 69% of patients who underwent the MCF approach but in only 33% of patients for whom the RS approach was used. The RS approach was used for larger tumors (mean diameter 15 mm) and the MCF procedure for smaller tumors (mean diameter 9 mm). One hundred percent of patients had facial function H/B grade II or better, regardless of approach. CONCLUSION: Hearing function can be reliably preserved in a high percentage of selected patients undergoing resection of vestibular schwannoma.[Abstract] [Full Text] [Related] [New Search]
