OBJECT
Following shunt placement for treatment of normal-pressure hydrocephalus (NPH), several patients suffered hearing loss. The authors undertook a study to analyze this outcome.
METHODS
Sixteen patients in whom NPH was diagnosed were treated by placement of a ventriculoperitoneal shunt. Their hearing was assessed pre- and postoperatively by using pure tone audiometry. Two thirds of the ears tested showed a postoperative hearing loss of more than 10 dB. Recovery of the hearing loss occurred 6 to 12 weeks after shunt placement in 75% of the ears examined.
CONCLUSIONS
Although shunt insertion for treatment of NPH results in a decrease in hearing, most of the loss can be recovered.
目的
在采用分流术治疗正常压力脑积水（NPH）后，有几位患者出现了听力丧失。作者开展了一项研究来分析这一结果。
方法
16例被诊断为NPH的患者接受了脑室腹腔分流术治疗。术前和术后通过纯音听力测定法评估他们的听力。三分之二接受测试的耳朵术后听力损失超过10分贝。在接受检查的耳朵中，75%的耳朵在分流术后6至12周听力损失得到恢复。
结论
尽管采用分流术治疗NPH会导致听力下降，但大多数听力损失是可以恢复的。
