Retrolabyrinthine approach for cerebellopontine angle region surgeries
摘要
Abstract
OBJECTIVE To evaluate the application ofretrolabyrinthine approach in cerebellopontine angel(CPA) region surgeries.METHODS A total of 42 patients underwent microscopic-endoscopic cooperative surgeries for CPA lesions via retrolabytinthine approach were reviewed.They were hospitalized from January 1st 2011 to January 1st 2016 in our institution.The microscopic-endoscopic technique was applied in all surgeries.RESULTS Complete removal was obtained in all tumor resections and satisfactory symptom-relief was achieved in all microvascular decompressions and neurectomies.In cases with acoustic neuroma and cholesteatoma,useful hearing (AAO-HNS classes A,B and C) was obtained in 66.7％(6/9) patients.No facial paralysis and postoperative complications such as cerebrospinal fluid leakage occurred during follow-up.In cranial nerve rhizopathies cases,complete relief was achieved in all patients.No facial paralysis and other lower cranial nerve dysfunction occurred.CONCLUSION With the preservation of labyrinthine structures,the microscopic-endoscopic cooperative surgeries for CPA lesions via retrolabytinthine approach could increase the hearing preservation level without facial nerve injury.Retrolabyrinthine approach is a good option for cranial nerve rhizopathies and tumors smaller than 15 mm in diameter without involvement of the fundus of internal auditory canal in the CPA region.关键词
