A PROSPECTIVE OBSERVATIONAL STUDY TO ANALYZE RESULTS OF ANTERIOR TUCKING TECHNIQUE OF TYPE-1 TYMPANOPLASTY IN PATIENT OF CHRONIC OTITIS MEDIA MUCOSAL TYPE

Abstract

Introduction: Chronic otitis media(COM) is a major public health problem in children and adults. Tympanic membrane (TM) perforations lead to recurrent ear infections and hearing loss. Tympanoplasty has been the surgery of choice for the pars tensa perforation of tympanic membrane. Anterior, large and subtotal perforations have a high chance of residual perforation after surgery due to lack of anterior support. To overcome this problem various modications are done in two basic method (overlay and underlay) of graft placement. Aim of our study was to evaluate the results of anterior tucking technique of type-1 tympanoplasty. Methodology: A prospective observational study was done. Total 40 cases of COM inactive mucosal disease with anterior quadrant perforaion enrolled in study. Detailed history, examination and preoperative and postoperative pure tone audiometric(PTA) ndings were noted down preformed proforma. Results: Out of 40 patients graft uptake rate was 90.00% (36 cases). 36 patients had showed the improvement in PTA with average air bone gap gain of 12.02 dB. Conclusions: Anterior quadrant perforation of tympanic membrane requires support to prevent graft medialization and residual perforation. Anterior tucking technique in Type-1 Tympanoplasty increase graft uptake in large, anterior or subtotal perforation with good post-operative hearing outcome.
