Myringoplasty: comparison between different tissues grafts, a prospective study

Abstract

Myringoplasty is done to repair simple perforations of the pars tensa. Different tissue grafts such as temporalis fascia, lobule fat, tragal perichondrium, cartilage from tragus and helix, cartilage-perichondrium composite graft and vein grafts have been used historically with varying success rates. In this study, we have used temporalis fascia, ear lobule fat and tragal perichondrium as graft material for myringoplasty and divided the study population into three groups based on the graft used. The outcome of the surgery across the three groups have been compared in terms of successful graft uptake and hearing improvement to less than or equal to 25 dB using pure tone audiometry. The group where temporalis fascia was used showed greater graft uptake rate (88.71%). Hearing improvement was however comparable in all the three groups (80.64% in the temporalis fascia group, 81.57% in the lobule fat group & 81.25% in the perichondrium group).
