[Application of the endoscope assisting in retrosigmoid approach vestibular schwannoma resection].

Abstract

OBJECTIVE:

To explore application of endoscope assisting in retrosigmoid approach vestibular schwannoma resection and its signification.

METHOD:

Through retrosigmoid approach with endoscope assisting, vestibular schwannoma in the cerebellopontine angle was removed in 12 cases. Assessment of function of facial nerve and auditory was made for all patients preoperative and postoperative.

RESULT:

Vestibular schwannoma in 12 patients were removed completely, then the facial nerve and the acoustic nerve were preserved after tumor removal. No complication was found in six months. We observed the hearing loss in postoperative patients, and there is no difference in facial nerve function between preoperative and postoperative. The alteration of auditory and facial nerves functions is no difference between two retrosigmoid approach groups with or without endoscope assisting.

CONCLUSION:

Application of endoscope assisting in retrosigmoid approach can be helpful for totally resection of vestibular schwannoma in inner acoustic meatus without lesion of canalis semicircularis and glomus jugulare. Application of the endoscope assisting in retrosigmoid approach is helpful to provide the precise information of CPA anatomic structure and decrease the incidence rate of complication.
