[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.
