To investigate the diagnosis of common congenital ossicular chain malformation and the efficacy of ossicular chain reconstruction. Fourteen cases with 15 ears of congenital ossicular chain malformation were included, consisting of 10 cases unilateral conductive hearing loss(10 ears), 1 case bilateral conductive hearing loss (2 ears) and 3 cases unilateral mixed hearing loss with significant conductive hearing loss(3 ears). Tympanoplasty was proceed on all 15 ears, 1 ear was proceed by loosen the cartilage fixation of ossicular chain and tympanic cavity wall. Fourteen ears were proceed with ossicular chain reconstruction, including 3 ears with TORP,10 ears with PORP and 1 ear with artificial stapes operation. The efficacy was measured by comparing the values of air bone gap(ABG) before and after the operation. The average ABG of pre-operation was 39.9 dB, the ABG for 3 week and 6 to 8 months after operation were 22.3 dB and 19.6 dB, which were 17.6 dB and 20.3 dB improve respectively(=22.10, <0.01 and =12.813，<0.01). Operation is the first choice for those conductive hearing loss causing by simple congenital ossicular chain malformation, relevant ossicular chain reconstruction due to particular situation of the surgery can significantly improve hearing.
探讨常见先天性听骨链畸形的诊断及听骨链重建的疗效。纳入14例15耳先天性听骨链畸形患者，其中单侧传导性听力损失10例（10耳），双侧传导性听力损失1例（2耳），单侧混合性听力损失伴显著传导性听力损失3例（3耳）。15耳均行鼓室成形术，1耳行听骨链与鼓室壁软骨固定松解术。14耳行听骨链重建术，其中3耳植入全听骨赝复物（TORP），10耳植入部分听骨赝复物（PORP），1耳行人工镫骨手术。通过比较手术前后气骨导间距（ABG）值评估疗效。术前平均ABG为39.9 dB，术后3周及6至8个月时ABG分别为22.3 dB和19.6 dB，分别改善了17.6 dB和20.3 dB（=22.10，<0.01；=12.813，<0.01）。对于单纯先天性听骨链畸形所致传导性听力损失，手术是首选，根据手术具体情况进行相关听骨链重建可显著提高听力。
