    Abstract:
    Objective:To evaluate the value of of autologous cartilago auriculae in posterior wall of external auditory canal reconstruction and tympanoplasty after modified radical mastoidectomy.Method:To determine the outcome of surgery for chronic suppurative otitis media with choleteatoma. The open mastoidectomy and tympanoplasty were performed on sixty patients aged 20-62 years old, and the average age was（43.16±9.43）years old, which includes 31 males and 27 females at our department in the period from September 2011 to September 2014. 58 patients all underwent modified radical mastoidectomy.Study group chose collected intraoperative cortical mastoid bone as a filler combined with autologous cartilago auriculae and temporal fascia muscle-periosteal flap covering the cavity and tympanoplasty.Control group chose collected intraoperative cortical mastoid bone as a filler temporal fascia muscle-periosteal flap covering the cavity. The hearing improvement at the time of achieving dry ear,3 months and 6 months after surgery were evaluated for both groups.Result:There are significant differeence between two groups in improvement of hearing and dry ear time,according to follow-up and analysis of therapeutic efficacy(P <0.05), There was no recurrence of cholesteatoma in 2 groups.Conclusion:The application of autologous cartilago auriculae in posterior wall of external auditory canal reconstruction and tympanoplastycan that can get more in line with the external auditory canal and the volume of physiological structure state of near normal tympanic cavity, dry ear and hearing improvement was satisfied.The autologous cartilago curiculae is suitable for repairing materials of open radical operation.
