Abstract :

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.
