Abstract:
Objective To explore the microsurgery technique and outcome of expanding translabyrinthine ap-proach resection large acoustic neuroma .Methods We have retrospectively studied clinical data and follow -up re-sults of 4 patients of large acoustic neuroma (≥5 cm ,the largest was 8 cm ;3 cases with servere sensorineualt hear-ing loss ,1 case with high frequenoy hearing loss ;1 case with blindness) in our hospital between January 2013 and April 2013 .All patients received expanding translabyrinthine approach microsurgery to resecting the tumors .Post-operative follow -up was 6~10 months .Results The large acoustic neuroma of 4 cases were totally removed via MRI reexamination after operation .Facial nerve in 3 cases were dissection retained ,and 1 case received facial nerve anastomosis .Six months after operatin ,one patient’s facial nerve function recovered from level Ⅲ to level Ⅱ ,the patient underwent facial nerve anastomosis with facial paralysis level Ⅵ recovered to level Ⅳ ,and the vision of pa-tient with blindness completely recovered to normal .Conclusion The expanding translabyrinthine approach can to-tally resect large acoustic neuroma and preserve facial nerve function .
