Comparative Study between Tympanoplasty alone & Tympanoplasty Combined with Cortical Mastoidectomy in Safe Type of Chronic Suppurative Otitis Media

To compare the results of Tympanoplasty alone and Tympanoplasty with Cortical Mastoidectomy in safe type of chronic suppurative otitis media (CSOM) patients, in terms of graft uptake, perforation closure, improvement in hearing and disease eradication.

prospective study with in a tertiary referral hospital.

60 cases of safe type of chronic suppurative otitis media were selected. Tympanoplasty alone was done in 30 cases and Tympanoplasty combined with Cortical mastoidectomy was done in another 30 cases. Patients were reviewed postoperatively at 1^st 2^nd and 3^rd month to inspect the operated ear for graft uptake or any complication. Pure tone audiometry(PTA) was done at 3^rd and 6^th month to evaluate the hearing improvement.

In our study, hearing gain in decibel (dB) in Tympanoplasty group was 13.69 and in Tympanoplasty combined with cortical mastoidectomy was 10.65. Graft uptake was 93.3% in tympanoplasty group and 86.6% in Tympanoplasty combined with Cortical mastoidectomy. Recurrence of discharge was seen in 4 cases of Tympanoplasty. Though Tympanoplasty is beer in hearing improvement, graft uptake and clinical improvement is beer in Tympanoplasty with Cortical mastoidectomy, the difference in two groups is statistically insignificant.

Hearing improvement, graft uptake and clinical improvement were statistically incomparable in two groups. Combining cortical mastoidectomy with Tympanoplasty will not give additional benefits in terms of hearing gain, disease clearance and graft uptake.
