摘　　要：目的探讨颅脑外伤对听力的影响，以供今后的临床工作参考。方法选择2010年8月至2013年7月收治的颅脑外伤患者70例作为观察组，以同期健康体检的正常成年人70例作为对照组，均进行听性脑干反应检查。对比两组患者阈值、各波潜伏期和波间期的差异。结果与对照组对比发现，观察组阈值明显较大，各波潜伏期明显较长，差异具有统计学意义（ P ﹤0.05）。观察组Ⅲ~Ⅳ波间期、Ⅰ~Ⅴ波间期明显较对照组长，差异具有统计学意义（ P﹤0.05）。Ⅰ~Ⅲ波间期组间比较，差异无统计学意义（ P ﹥0.05）。结论颅脑外伤患者多伴有不同程度的听力损害，采用听性脑干反应检查有助于识别听力损害情况，值得临床推广应用。Objective To investigate the effect on hearing after the craniocerebral trauma,which can used for future clinical reference. Methods 70 cases with traumatic brain injury from Aug. 2010 to Jul. 2013 in our hospital were included into the observation group. 70 cases with normal adults were selected as control group. The auditory brainstem response was recorded. The threshold,the latency and duration of sex differences of the groups were compared and analyzed. Results Compared with control group,the threshold of observation group was larger,latency was longer. The difference was statistically significant（ P ﹤0. 05）. The wave interval,III ~ IV wave interval of two groups were compared,Ⅰ ~Ⅴ interpeak latency was longer,the difference was statistically significant（ P ﹤0. 05）. Comparison of Ⅰ ~ III wave interval,no significant difference was detected（P﹥0. 05）. Conclusion Different degree of hearing impairment craniocerebral trauma patients with auditory brainstem response was detected. The examination can be curative effect has certain advantages. This method is worth to be popularized in future clinical work.
