A total of 40 patients with epidermoid cysts of the cerebellopontine angle (CPA) underwent surgery between 1980 and 1993. Total resection was achieved in 30 cases (75%); in 10 cases (25%) parts of the cyst capsule were left because they adhered to the brainstem and vascular structures of the CPA. One patient with very large bilateral epidermoid cysts, who underwent complete bilateral resection in one stage, died of pulmonary aspiration and infection. As of their latest clinical and radiological follow-up examinations (mean 5.7 years), 93% of the patients are able to lead useful lives. Three cases of cyst regrowth have been observed thus far. Modern radiological tools and microsurgery techniques have considerably improved the completeness of cyst resection and reduced postoperative mortality and morbidity rates; however, there still are some cases in which complete resection is impossible without producing severe neurological deficits.
1980年至1993年间，共有40例桥小脑角（CPA）表皮样囊肿患者接受了手术。30例（75%）实现了全切；10例（25%）因囊肿包膜与脑干及CPA的血管结构粘连而残留部分囊肿包膜。1例患有非常大的双侧表皮样囊肿的患者，在一期手术中接受了双侧全切，死于肺吸入和感染。截至他们最近的临床和影像学随访检查（平均5.7年），93%的患者能够过上有意义的生活。迄今为止，已观察到3例囊肿复发。现代影像学工具和显微外科技术显著提高了囊肿切除的完整性，降低了术后死亡率和发病率；然而，仍有一些病例在不产生严重神经功能缺损的情况下无法实现全切。
