[Evaluation of healing effect for simultaneously tympanoplasty in treating chronic suppurative otitis media with cholesteatoma and/or granulation tissue].

OBJECTIVE: This study was designed to discuss possibility and factors influencing healing effect for simultaneously tympanoplasty of chronic suppurative otitis media with cholesteatoma and/or granulation tissue. METHOD: For 52 cases with chronic suppurative otitis media with cholesteatoma (30 ears) and/or granulation tissue (22 ears), cleaning lesion with simultaneously tympanoplasty was surgical procedure, among them, 12 ears treated with single tympanoplasty, 40 ears treated with mastoidectomy and tympanoplasty. RESULT: All cases had dry ears without recurring cholesteatoma. Among them, hearing of 5 patients improved more than 30 dB, 9 ears improved from 20 to 29 dB, 31 ears improved from 10 to 19 dB and 7 ears improved less than 10 dB. Hearing of no cases reduced than that in preoperation. CONCLUSION: Simultaneously tympanoplasty would be carried out possible in treating chronic suppurative otitis media with cholesteatoma and/or granulation tissue. There were two important factors influencing hearing improvement, which concluded effective area of tympanic membrane concussion, activity of stapes and/or stapes footplate. The main cause for failure in hearing improvement would be eustachian tube obstruction.
