本文报告桥小脑角表皮样囊肿25例,对临床所见,诊断,以及外科治疗结合文献进行讨论。桥小脑角表皮样囊肿对听力及前庭功能影响比桥小脑角其它肿瘤少见,对诊断有参考价值。青年人桥小脑角表皮样囊肿多有三叉神经痛发作,客观检查甚至可以没有感觉障碍。作者主张枕下入路Dandy手术,常能发现表皮样囊肿。如囊壁与脑干或大血管粘连时,不要勉强切除,以防意外。事实上,这种肿瘤比其它良性肿瘤复发率低。
This article reports 25 cases of cerebellopontine angle epidermoid cysts, clinical observations, diagnosis, and surgical treatment of the literature are discussed. The cerebellopontine angle epidermoid cyst affects hearing and vestibular function more than other tumors of the cerebellopontine angle and has a reference value for diagnosis. Young people with cerebellar angle epidermoid cyst more trigeminal neuralgia attack, objective examination can even have no sensory disturbance. The authors advocate suboccipital approach Dandy surgery, often found in epidermoid cysts. Such as wall and brain stem or large blood vessels adhesions, do not barely removed to prevent accidents. In fact, this kind of tumor has a lower recurrence rate than other benign tumors.
