目的：探索先天性中外耳畸形患者耳道再造与鼓室成形术后听力改善情况，为此类患者方案选择提供参考。方法回顾性分析2006年6月～2012年12月我们进行外耳道再造与鼓室成形患者中有术前术后听力的41例（41耳）的情况。结果手术采用听骨链松解41.5%(17/41)，Porp植入46.3%(19/41),Torp植入7.3%(3/41)，内耳开窗4.9%(2/41)。术前术后0.5k、1k、2k、4k平均气导听阈值分别为(58 dB/53dB）,（64 dB/52dB）,（73 dB/73dB）,（62 dB/46dB）.结论听骨链松解与Torp植入术后听力改善不明显,Porp植入和内耳开窗术后听力有明显改善,但未能达到正常听阈水平。

Objective To explore the hearing improvement after reconstruction of external auditory meatus (Re-EAMs) and tympanoplasty for patients with congenital deformation of the middle and outer ears, and provide reference for later treat?ment to these kinds of patients. Methods a retrospective analysis of 41 cases (41 ears) with preoperative and postoperative hearing findings undergone Re-EAMs and tympanoplasty patients with congenital deformation of the middle and outer ears in General Hospital of PLA during 2006.7-2012.12. Results The methods for operations were Ossicular chain loosening 41.5%(17/41),Porp implantation 46.3%(19/41), Torp implantation 7.3%(3/41) and inner ear fenestration 4.9%(2/41),with average air conduction hearing threshold pre-and post-operation for 0.5k、1k、2k、4k (58 dB/53dB),(64 dB/52dB),(73 dB/73dB)and (62 dB/46dB)respectively. Conclusion Hearing improvement is not obvious after ossicular chain loosening and Torp implan?tation, while significant for Porp implantation and inner ear fenestration, but can’t reach the normal hearing threshold level.
