To assess the efficacy of intraoperative brainstem auditory evoked responses (BAER) in predicting postoperative hearing improvement in surgery for conductive hearing loss.
A prospective study of consecutive patients undergoing surgery for conductive hearing loss under general anesthesia by a single surgeon.
A tertiary care university affiliated medical center.
All patients undergoing surgery for conductive hearing loss by the senior author between June 25, 1993 and March 20, 1995.
Pre- and postreconstruction intraoperative BAERs; pre- and postoperative pure tone and speech audiometry.
Changes in audiometric pure tone air-conduction thresholds, bone-air gaps (BAG), and speech reception thresholds (SRT), compared with changes in BAER wave five (V) latencies.
A decrease in the wave V latency on the intraoperative BAER correlates significantly with improvement in postoperative pure-tone air-conduction, BAG, and SRT using chi 2 and linear regression analyses.
Improvement in intraoperative BAER correlates with postoperative hearing improvement in surgery for conductive hearing loss done under general anesthesia in our population.
评估术中脑干听觉诱发电位（BAER）在预测传导性听力损失手术术后听力改善方面的疗效。
对由单一外科医生在全身麻醉下进行传导性听力损失手术的连续患者进行的前瞻性研究。
一所三级护理大学附属医院。
1993年6月25日至1995年3月20日期间由资深作者进行传导性听力损失手术的所有患者。
重建术前和术后术中BAER；术前和术后纯音及言语测听。
与BAER波V潜伏期变化相比，测听纯音气导阈值、骨气导间距（BAG）和言语接受阈值（SRT）的变化。
使用卡方检验和线性回归分析，术中BAER波V潜伏期的缩短与术后纯音气导、BAG和SRT的改善显著相关。
在我们的研究人群中，全身麻醉下进行的传导性听力损失手术中，术中BAER的改善与术后听力改善相关。
