A study of hearing improvement gained after tympanoplasty using various methods in cases of CSOM
Keywords:Tympanoplasty, CSOM, Mastoidectomy
Background: Chronic otitis media (COM), is a common ailment with which patients present to the ENT OPD. In patients with COM, the active infection needs to be controlled following which the definitive line of management is surgery. Tympanoplasty is the surgery performed with the goals of establishing an intact tympanic membrane, eradicating middle ear disease, creating an air-containing middle ear space and restoring the hearing by building a secure connection between the ear drum and the cochlea.
Methods: 50 patients presenting with CSOM in ENT OPD at Medical College. Preoperative audiometry was done before tympanoplasty, followed by post-operative audiometry after 3 months.
Results: The mean air-bone gap closure was 12.06 dB; with type I tympanoplasty with cortical mastoidectomy giving a maximum mean improvement of 16db. Minimum mean improvement of 1db was seen in type IV with modified radical mastoidectomy.
Conclusions: Type I tympanoplasty with cortical mastoidectomy is a far superior method of surgical treatment of CSOM than all other methods.
