[The application of tragal cartilage-perichondrium in open method tympanoplasty].

Objective

To investigate the efficacy of the application of tragus cartilage-perichondrium in open method tympanoplasty.Method:Thirty patients with middle ear cholesteatoma were treated with open method tympanoplasty and titanium ossicular prosthesis replacement surgery utilized the tragus cartilage-perichondrium, the air-bone gap and the recovery of tympanic membrane were observed before and after operation.Result:Thirty ears achieved primary healing. After a follow-up of 12 months, no prosthesis extrusion and atticus lateral wall collapse were observed. The average air-bone gaps reduced by 13 dB in average.

Conclusion

The tragus cartilage-perichondrium is an appropriate material in open method tympanoplasty.
