摘　　要：目的：比较在闭合式鼓室成形术中应用钛质与陶瓷人工听骨的治疗效果。方法回顾性分析2008年1月～2012年12月采用人工听骨进行听力重建的闭合式鼓室成形术150例（155耳）患者的临床资料，其中，钛质听骨组122例（127耳），陶瓷听骨组28例（28耳），术后随访12个月，比较两组术前及术后12个月0．5、1．0、2．0和4．0 kHz气导平均听阈及气骨导差（air bone gap ，ABG）。结果钛质听骨组术后12个月术耳听力提高＞15 dB者117耳（92．13％ ），ABG≤20 dB者106耳，手术前后平均气导听阈分别为58．22 ± 4．83、41．82±6．83 dB HL ， ABG分别为28．57±5．88、13．27±5．82 dB ，手术后均较术前改善，差异有统计学意义（均为 P＜0．05），听力重建成功率达83．46％（106／127）；陶瓷听骨组听力提高＞15 dB者5耳（17．86％ ），ABG≤20 dB者3耳（10．71％ ），手术前后平均气导听阈分别为57．26±5．32、50．67±5．38 dB HL ，ABG分别为27．95±6．24、21．85±6．54 dB ，手术前后比较差异无统计学意义（ P＞0．05），听力重建成功率为10．71％（3／28）。钛质听骨组疗效明显优于陶瓷听骨组（ P＜0．05）。结论闭合式鼓室成形术中应用钛质人工听骨行听力重建较陶瓷人工听骨效果好。Objective To investigate the therapeutic effects of titanium artificial auditory ossicles in closed type mastoid radical tympanoplasty ,in comparison with ceramic artificial auditory ossicles .Methods A retrospec‐tive analysis was done on of 150 patients （155 ears） with the closed type of mastoid radical tympanoplasty using arti‐ficial auditory ossicles for hearing reconstruction （from January 2008 to December 2012） ,cund were ,and followed up for 12 months .Based on the two kinds of artificial auditory ossicle materials ,the group was divided into two ：122 cases （127 ears） for the titanium auditory ossicle group and 28 cases （28 ears） for the ceramic auditory ossicle group .We compared the average air conduction hearing threshold and air bone gaps （ABG） at 0 .5 ,1 .0 ,2 .0 ,and 4 .0 kHz ,at preoperative 6 months and postoperative 6 ,12 months .Results For the Titanium artificial auditory os‐sicle group：117 ears （92 .13% ） had hearing threshold improvement 〉15 dB HL ,106 ears of the ABG change ≤20 dB ,which were statistically significant .The total success rate of hearing reconstruction was 83 .46% （106/127） . For the ceramic auditory ossicle group：5 ears （17 .86% ） had hearing threshold improvement〉15 dB HL ,3 ears （10 .71% ） of the ABG change ≤20 dB ,which was no statistical significance between the two groups .Conclusion The hearing reconstruction effects of titanium artificial auditory ossicle in closed type mastoid radical tympanoplasty is excellent .It is suitable for application in closed-mastoidectomy tympanoplasty ideal artificial auditory ossicle .
