头颅外伤后听觉损伤诊断的临床分析

目的 探讨头颅外伤后听觉损伤的诊断方法。方法 对66例患做电测听、声阻抗及脑干诱发电位检查。结果 66例患电测听检查异常率为96．97％，声阻抗检查异常率为36．36％，脑干诱发电位检查异常率为39．39％，电测听与脑干诱发电位检查对比差异有显性（P＜0．01），声导抗与脑干诱发电位检查对比无显差异（P＞0．05）。结论：头颈外伤后听力损伤的诊断应以脑干诱发电位检查作为客观指标，结合声阻抗检查更有临床实用价值。

Clinical analysis on diagnosis of hearing injury in patients with skull wound

Objective To explore the clinical diagnostic of method hearing injury in patients with skull wound. Methods 66 patients with skull wound were checked by pure tone audiometry, acoustic immittance and auditory brainstem respons (ABR). Results The unusual rate of pure tone audiometry was 96.97%. The abnormal rate of acoustic immittance was 36.36%. The unusual rate of ABR was 39.39%. There was significantly difference between the prue tone audiometry and ABR. There was no difference between acoustic immittance and ABR. Conclusion The diagnosis of hearing injury patients with skull wound should depend on ABR as examination standard. Combining ABR with acoustic immittance was better to the clinical diagnosis.
