【目的】探讨并比较耳后进路夹层法与内植法鼓膜修补术疗效。【方法】收集需行鼓膜修补术患者80例（92耳），按手术方法分为夹层法组42例（46耳）与内植法组38例（46耳）。分别观察两组术后听力恢复情况、术前术后言语频率平均听阈、术后3个月鼓膜情况、术后6个月愈合率。【结果】术后听力恢复情况夹层法优于内植法（P ＜0．05）；夹层法术后言语频率平均听阈明显高于内植法（P ＜0．01）；术后随访3个月后两组引起再穿孔、鼓膜内陷的发生有统计学差异（ P ＜0．05）；术后6个月愈合率比较，夹层法优于内植法，两组有统计学差异（ P ＜0．05）。【结论】耳后进路夹层法与内植法鼓膜修补术短期疗效相当，但前者更有利于听力恢复，是治疗鼓膜穿孔的较为理想的方法。“,”Objective To explore and compare the efficacy between postauricular sandwich method and underlay method for tympanic membrane repair .[Methods] Totally 80 patients(92 ears) requiring tympanic membrane repair were collected and randomly divided into sandwich method group ( n =42 ,46 ears) and un-derlay method group( n =38 ,46 ears) .Postoperative auditory rehabilitation ,pre-and post-operation speech frequency ,average auditory threshold ,tympanic membrane 3 months after operation and the healing rate 6 months after operation were observed .[Results] The postoperative auditory rehabilitation in sandwich method group was better than underlay method group( P<0 .05) .Postoperative speech frequency and average audito-ry threshold in sandwich method group were obviously higher than those in underlay method group ( P <0 .01) .There was significant difference in the incidence of reperforation and otopiesis 3 months after the fol-low-up between two groups( P<0 .05) .There was significant difference in the healing rate 6 months after the operation between two groups ( P < 0 .05) .[Conclusion]The short-term efficacy in postauricular approach sandwich method is the same as that in underlay method ,but it is more beneficial for auditory rehabilitation , so it is an ideal method for the treatment of tympanic membrane perforation .
