中文摘要：

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。

英文摘要：

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.
