摘　　要：目的分析爆震性耳聋的听力改变及相关因素。方法对22例(35耳)急性声创伤患者作定期的听力追踪测试,测得爆震后平均28h、4d、9d、20d的听阈变化。同时予以药物、手术等方法治疗,进行疗效分析。结果本组35耳爆震伤病例中感音神经性、传导性耳聋及混合性耳聋比例接近,分别31%、37%和33%;鼓压导抗曲线"A"型占51%。22例患者(35耳)经治疗后听力恢复正常8例(45.7%),显效11例(40.0%),无效3例(14.2%),总有效率为85.7%。结论爆震性聋听力经过积极治疗,早期恢复速度较快,逐渐变慢。早期听力损害严重者恢复不良,以高频听力损害为主。应采取有效防护措施避免听力损害。Objective To analyze the hearing changes after acute acoustic trauma and discuss the correlative factors.Methods A series of audiometry and analysis on 22 cases （35 ears）of explosive deafness with intact drum were performed averagely after blast 28 hours,4 days,9 days,20 days and 21.6 days. At the same time they were given to drugs and surgery and other treatment methods. Results In 35 ears of explosive deafness, sensorineural deafness,conductive deafness and mixed deafness accounted for 31%,37%and 33%, respectively. The curves of tympanum function were mainly type A up to 51%. The recruitment rate of hearing in 22 cases（35 ears）was 85.7%,hearing recovered to the normal level in 8 cases （45.7%）.Including 11 cases （40.0%） of remarkable efficiency and 3 cases （14.2%） of inefficiency. Conclusion The recovery of hearing is quickly at early period of blast,and then becomes slowly gradually.The serious hearing trauma have a tendency to incomplete recovery.The blast and impulse have a severe damage to internal ears in an irreversible manner.
