Diagnosis and treatment of cystic acoustic neuroma

目的 总结囊性听神经瘤的临床特点及治疗效果。 方法 2 2例患者术前均应用CT和MRI进行诊断 ,应用乙状窦后入路手术切除肿瘤。术中证实 ,术后病理确诊囊性听神经瘤。结果 2 2例肿瘤全切除 18例 ,术后面神经功能分级 :Ⅱ级 4例、Ⅲ级 7例、Ⅳ级 3例、Ⅴ级 2例、Ⅵ级 2例 ;次全切除 4例 ,面神经功能Ⅱ级。 结论 由于囊性听神经瘤的临床特点及疗效差 ,应把它作为一种特殊亚型来处理。

Objective To study the clinical features and treatment of cystic acoustic neuroma. Methods Twenty-two patients with cystic acoustic neuromas were diagnosed by CT and MRI preoperatively, and the tumors were resected by retrosigmoid approach, and verified by pathological studies. Results Of the 22 patients, 18 had tumors totally resected (postoperative house Brackman facial nerve grading: grade Ⅱ in 4 patients, Ⅲ in 7, Ⅳ in 3,Ⅴin 2,Ⅵin 2) and 4 had tumors subtotally resected. Conclusion Because of its specific clinical features and poor operative results, cystic acoustic neuroma should be regarded as a specific subtype. [
