Abstract

Objective: To study the value of neuroendoscopy assisted microneurosurgery technique in the treatment of posterior cranial fossa lesion. Methods: Clinical data of 36 patients with posterior fossa lesions who accepted neuroendoscopy assisted microneurosurgery (NEAM group) in the department of neurosurgery of the First Affiliated Hospital of Chongqing Medical University, from January 2014 to December 2016, were retrospectively enrolled. A total of 113 cases diagnosed with the same lesions and accepted conventional microneurosurgery (non-NEAM group) in the same period were analyzed as control group. The total tumor resection rate, postoperative leakage of cerebrospinal fluid, intracranial infection, operating time and the recovery of facial nerve function were compared between the two groups. Results: Ninety-three patients with acoustic neuroma were analyzed, which were divided into non-NEAM group 78 cases (removed posterior lip of internal auditory canal in different degrees) and NEAM group 15 cases (not removed posterior lip of internal auditory canal). The total tumor resection rate and postoperative facial nerve function had no significant statistical differences between two groups. The operating time of NEAM group was longer ...Continue Reading
