Objectives

1. Selection of patients of CSOM with conductive deafness to undergo various types of Tympanoplasty surgeries.

2. To document he� improvement after various types of Tympanoplasty surgeries in cases of CSOM by means of PTA.

Methods

A total of 50 cases of CSOM presented with he� loss were compiled after applying the inclusion and exclusion criterias. All the cases underwent

detailed otoscopic and audiometric examination. All the patients were treated surgically and were followed up after 3 months. Descriptive and

inferential statistical analysis has been carried out in this study.

Results

Comp� the preop and 3 months postop PTA, significant AB gap closure was seen in 30(60%) patients, remained same in 18(36%) patients and

worsened in 2(4%) patients.

Maximum improvement (75%) was seen in pre op 21–30 dB group. The mean preop AB gap calculated was 37.2�6.875 dB and mean postop AB

gap calculated was 27.08�9.9 dB.
