The objective of this study is to compare hearing improvements in the air-bone gap (ABG) after type III tympanoplasties, comparing between incus transposition (IT) and partial ossicular replacement prosthesis (PORP).
Publications in English were searched in PUBMED database and were systematically reviewed. A total of 14 articles were included, obtaining 1055 patients, 614 for the IT group and 441 for the PORP group. Preoperative ABG, postoperative ABG, dB gain and ABG closure rate were compared.
IT group: preoperative ABG of 31.74 dB (SD 10.51); postoperative ABG of 18.97 dB (SD 10.6); dB gain of 12.76 dB (SD 14.97); and ABG closure rate of 64.48%. PORP group: preoperative ABG of 28.02 dB (SD 10.47); postoperative ABG of 16.27 dB (SD 10.45); dB gain of 11.75 (SD 15.02); and ABG closure rate of 71.32%. No significant statistical difference was found in dB mean gain between groups (p > .05), although a difference was found in the ABG closure rate between groups favouring PORP series (p < .05).
An improvement in hearing results was observed within both groups after type III tympanoplasty. There is no difference in decibels gained between both ossiculoplasty materials, but a better closure rate (%) was observed in the PORP group.
本研究的目的是比较Ⅲ型鼓室成形术后气骨导间距（ABG）的听力改善情况，比较砧骨移位（IT）和部分听骨链置换假体（PORP）之间的差异。
在PUBMED数据库中检索英文出版物并进行系统评价。共纳入14篇文章，获得1055例患者，IT组614例，PORP组441例。比较术前ABG、术后ABG、dB增益和ABG闭合率。
IT组：术前ABG为31.74dB（标准差10.51）；术后ABG为18.97dB（标准差10.6）；dB增益为12.76dB（标准差14.97）；ABG闭合率为64.48%。PORP组：术前ABG为28.02dB（标准差10.47）；术后ABG为16.27dB（标准差10.45）；dB增益为11.75（标准差15.02）；ABG闭合率为71.32%。两组间dB平均增益无显著统计学差异（p＞0.05），但两组间ABG闭合率存在差异，PORP组更优（p＜0.）。
Ⅲ型鼓室成形术后两组听力结果均有改善。两种听骨成形材料在增益分贝数上无差异，但PORP组的闭合率（%）更高。
