作者对在1976年1月至1985年12月10年间由于术后听神经瘤的残留或复发而进行再次手术的23例病人(男6,女17)进行了研究和分析。其中19例进行过2次手术,4例进行过3次手术。第一次手术与第二次手术相隔时间为5个月～8.2年(残留肿瘤患者)或3.3年～17年(肿瘤复发患者)。大多数患者在第二次手术时有一个以上的症状和体征,症状的出现取决于初次手术后残留的颅神经和小脑功能。最常见的是共济失调(16例),面部感觉异常(13例),头痛(9例)。其中8例无症状者是在随访中经强化CT(2例)或核磁共振成像(1例)而发现。由于初次手术后第Ⅷ颅神经丧失功能早期
The authors studied and analyzed 23 patients (6 males and 17 females) undergoing reoperation between January 1976 and December 10, 1985 due to residual or recurrent acoustic neuroma. Of these, 19 patients underwent 2 surgeries and 4 patients underwent 3 surgeries. The interval between the first operation and the second operation was 5 months to 8.2 years (residual tumor patients) or 3.3 years to 17 years (recurrence of tumor patients). Most patients have more than one symptom and sign during the second operation. The appearance of symptoms depends on the residual cranial nerves and cerebellar function after the initial operation. The most common are ataxia (16 cases), facial paresthesia (13 cases), and headache (9 cases). Eight of these asymptomatic individuals were found during follow-up by enhanced CT (2 cases) or MRI (1 case). Early VIII cranial nerve loss due to early surgery
