Outcomes of circumferential tympanomeatal flap tympanoplasty in large central perforation

Abstract

<p class="abstract"><strong>Background:</strong> Tympanoplasty is the commonest procedure performed in patients with chronic otitis media. Circumferential elevation of tympanomeatal flap and underlay graft placement is thought to be a good surgical technique as it ensures elevation of canal skin over the Eustachian tube area to form a good assemble between the temporalis graft and the flap to increase the success rate. In our study we intend to study the surgical and hearing outcome in patients undergoing tympanoplasty with circumferential tympanomeatal flap in large central perforations.</p><p class="abstract"><strong>Methods:</strong> A prospective study with 25 patients in a tertiary care hospital for a period of 2 years, who underwent circumferential tympanomeatal flap tympanoplasty. Patients were followed up on one month and two months. Graft outcomes and hearing outcomes were studied. </p><p class="abstract"><strong>Results:</strong> Graft uptake was 92%. Blunting was noticed in 4% and medialisation in 4% of patients in circumferential group. Average air-bone gap closure achieved was 17.468 dB.</p><p><strong>Conclusions:</strong> Circumferential flap elevation in tympanoplasty is an effective surgical technique in patients with anterior and large central perforations with satisfactory outcomes. </p>
