Abstract：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.
