Hearing Assessment After Total Annular Excision Tympanoplasty- Our Institutional Experience

ObjectiveThe objectives of this study were to record graft uptake, hearing status and any complication(s) after total annular excision (TAE) tympanoplasty and to compare them with previously operated underlay tympanoplasty patients.DesignProspective study.MethodsPatients with chronic otitis media mucosal type aged between 15-45 years attending our outpatient department were assessed and eligible patients who gave consent for the study were included.ResultPatients of chronic otitis media mucosal type who underwent TAE tympanoplasty had 80% graft uptake. Post TAE tympanoplasty patients had good hearing assessed by tuning fork test and pure tone audiometry. Maximum improvement in hearing was seen at 500Hz frequency by pure tone audiometry in TAE tympanoplasty group. Histopathological examination of remnant tympanic membrane showed mucosalization.ConclusionTAE tympanoplasty can effectively prevent development of granular myringitis.
