Aim: aim to assess the eustachian tube function before and after tympanoplasty.
Materials and methods: The present prospective comparative study was conducted in the Department of ENT, Sri Krishna Medical College and Hospital, Muzaffarpur, Bihar India .Among 60 patients confirmed with the diagnosis of chronic otitis media. Preoperative PTA and eustachian tube function tests were taken. Patients were then subjected to ear surgery.
Results: Majority of patients were young adults the mean age group was 28.16±6.61 years. Of these patients, 55.0% were males and 45.0% were females. Mean preoperative PTA was 40.32±3.41 and post operatively the PTA was 31.41±4.65 improved significantly (p<0.05).
