Twenty-three elderly patients with acoustic neuroma have been followed conservatively (no treatment) for a mean of 3.8 years. Five patients subsequently required ventricular shunting. Two patients required partial excision of their tumors (one previously treated by shunting). Eleven patients who have required no treatment have no significant complaints. There was significant variation in tumor growth rates making predictability for surgical intervention hazardous. A mean growth rate of 0.22 cm/year was noted. Our statistics suggest tumor removal in healthy patients with larger tumors at time of presentation; in other patients, conservative follow-up may be more appropriate.
23例老年听神经瘤患者接受了保守治疗（未治疗），平均随访3.8年。5例患者随后需要进行脑室分流术。2例患者需要部分切除肿瘤（其中1例之前已接受分流术治疗）。11例未接受治疗的患者无明显不适。肿瘤生长速度差异显著，使得手术干预的可预测性存在风险。观察到平均生长速度为每年0.22厘米。我们的统计数据表明，对于就诊时肿瘤较大的健康患者应进行肿瘤切除；对于其他患者，保守随访可能更为合适。
