A Study on Outcome of Underlay, Overlay and Combined Techniques of Myringoplasty

Abstract

Myringoplasty is a procedure which deals on repair of the tympanic membrane. This procedure can be done via postaural, endaural or endomeatal route. Various grafts such as temporalis fascia, vein graft, perichondrium are used. The technique can be categorized as underlay, overlay, interlay or its combination depending on the placement of the graft material. This study was done to compare underlay, overlay and combined technique in terms of the closure of the membrane defect, postoperative complications and over all success rates. Apart from few complications, this study revealed over all success rate was best with combined technique but the difference was not significant statistically when the methods are comparable among them.

Comparative Study of Underlay Tympanoplasty with Temporalis Fascia and Tragal Perichondrium

“…This study also compares well with Sunita Chhapola, Inita Matta (2011) 58 whose postoperative hearing assessed after 6 months of surgery, with temporalis fascia graft showed air bone gap of less than 10dB in 82% of patients and more than 10dB in 18% patients, air bone gap closure with tragal perichondrium was less than 10 dB in 78% patients and more than 10dB in 22% of patients.…”

Outcome of Interlay Grafting in Type 1 Tympanoplasty for Large Central Perforation

“…Sengupta et al [8] in his study found maximum number of patients to have complaints of hearing loss and discharge (57.5 %) followed by complaint of only ear discharge in 25 % cases and only hearing loss in 12.5 %. In our study 20 cases (20 %) had tympanosclerotic patches in the tympanic membrane.…”

A Comparative study of the techniques of Myringoplasty - Overlay Underlay & Interlay

“…Underlay technique were done in 30 patients having dry ear done by conventional method and temporalis fascia graft was placed under the membrane remnant including the flap after elevating the tympanomeatal flap elevated along with annulus [18].…”
