Neuroendoscopy-assisted microsurgery for cerebellopontine angle tumours

Objective To discuss the utility and advantages of the neuroendoscopy-assisted microsurgery for cerebellopontine angle tumors by retrosigmoid approach. Methods A retrosigmoid craniotomy and neuroendoscopic assisted microsurgical tumor resection was performed on 33 patients with cerebellopontine angle tumors. Results Ten acoustic neuromas were resected completely with preservation of facial nerves. Total resection of tumor was carried out respectively in twenty-two cholesterotomas and one meningioma. No postoperative complications and death occurred in this series. Conclusion The neuroendoscopy-assisted microsurgery for the cerebellopontine angle tumors by retrosigmoid approach is helpful to improve the microsurgical treatment effect and lessen the operative risk.
