A study of operations on cases with cervical neurinomas

Abstract

Cervical neurinoma is a relatively rare condition and so the number of cases encountered by otolaryngology specialists and head and neck surgeons tends to be low. Intercapsular resection is a common treatment modality that preserves neurological function, but it requires some experience. In this paper, we clinically investigated 23 cases of cervical neurinoma for which intercapsular resection was performed by the same surgeon. The results indicated that intercapsular resection was effective for the preservation of neurological function postoperatively, and the surgical technique was presumed to be related to postoperative symptoms of neurological deficit. However, the reason why postoperative neurological deficit readily arises in the nerve of origin is unknown. Even in cases where intercapsular resection is conducted for intraparotid neurinoma, resection is only possible if transient paralysis is caused, and treatment options should include both surgery and follow-up.
