Abstract

Background: The cerebellopontine angle is a space defined by the pyramid anterolaterally, the tentorium superiorly, the pons medially and cerebellum dorsomedially. It is difficult to approach for its complication and vital structures. Objective: To see the outcome of surgery of cerebellopontine angle tumors at the Bangabandhu Sheikh Mujib Medical University. Results: Among the 24 patients 16(66.66%) were males. It was evident that 14(58.33%) belonged to the age group 41-60 years. It was documented that the majority 19(79.16%) of patients had vestibular schwannoma. Among the clinical signs and symptoms the highest group had hearing loss 20(80%). Among 24 patients the tumor was removed completely in 15(62.50%). Among the post operative complications 4(16.66%) developed facial palsy. 2(8.33%) of patients had lower cranial nerve palsy. After operation 1(4.16%) patient died due to aspiration pneumonia. Conclusion: Cerebellopontine angle tumor surgery is a very difficulty operation. But at a tertiary hospital, with help of microscope, we can remove the tumor completely. Bangladesh Journal of Neuroscience 2014; Vol. 30 (2): 90-95

桥小脑角肿瘤的手术疗效:附孟加拉班班杜谢赫穆吉布医科大学神经外科24例报告

背景:桥小脑角是一个由锥体前外侧、幕上、桥桥内侧和小脑背内侧所定义的空间。它的复杂性和重要结构使其难以接近。目的:观察孟加拉谢赫穆吉布医科大学桥小脑角肿瘤的手术效果。结果:24例患者中男性16例，占66.66%。41 ~ 60岁年龄组14例，占58.33%。其中19例(79.16%)为前庭神经鞘瘤。在临床体征和症状中，听力损失最高的组为20%(80%)。24例患者中肿瘤完全切除15例(62.50%)。术后并发症4例(16.66%)发生面瘫。2例(8.33%)为下脑神经麻痹。术后1例(4.16%)患者死于吸入性肺炎。结论:桥小脑角肿瘤手术是一项难度较大的手术。但是在三级医院，在显微镜的帮助下，我们可以完全切除肿瘤。孟加拉国神经科学杂志2014;Vol. 30 (2): 90-95
