Experience has shown that early removal of acoustic tumors results in less morbidity because the rate of surgical complications increases with tumor size. Nevertheless, acoustic tumors are benign and grow slowly--facts that support conservatism in elderly patients. We managed 21 patients with acoustic tumors over the age of 65. Eleven patients underwent immediate surgical excision. Ten patients were monitored clinically and with serial magnetic resonance imaging (MRI) or computed tomographic (CT) scans. To date, two of these patients have required surgical excision because of continued tumor growth. Our experience managing these patients both surgically and with "watchful waiting" is the subject of this report.
经验表明，早期切除听神经瘤可降低发病率，因为手术并发症的发生率会随着肿瘤大小的增加而上升。然而，听神经瘤是良性的且生长缓慢，这些事实支持对老年患者采取保守治疗。我们治疗了21例65岁以上的听神经瘤患者。11例患者接受了立即手术切除。10例患者接受了临床监测以及系列磁共振成像（MRI）或计算机断层扫描（CT）。迄今为止，这些患者中有2例因肿瘤持续生长而需要手术切除。我们对这些患者进行手术治疗和“观察等待”的经验是本报告的主题。
