A Comparative Study of Closure of Tympanic Membrane Perforation between Chemical Cauterization and Fat Plug Myringoplasty

Abstract

The purpose of closure of small dry tympanic membrane perforations is to restore the continuity of the tympanic membrane in order to improve hearing and decrease the incidence of middle ear infections. Small and cost effective procedures like Chemical Cauterization and Fat Plug Myringoplasty have been found to be effective in healing small central perforations with significant hearing improvement. A study was carried out in 69 patients with central perforations in the Department of ENT, Gauhati Medical College & Hospital for the duration of 1 year from August 11 to July 12. Out of 69 patients, 36 underwent Chemical Cauterization and 33 Fat Plug Myringoplasty. Pre-and post-operative hearing assessments of each patient were done and statistically analyzed. The success rate was found to be 83.33% and 90.9% respectively. In both groups, there was statistically significant hearing improvement with a P value 0.01. From our study, it was found that the two procedures are simple, reliable and also lessened the morbidity of the patient. Thus we recommend the use of these two official procedures for the treatment of central perforations of tympanic membrane less than 5 mm.

A Comparative Study of the Efficacy of Fat Plug Myringoplasty and Conventional Myringoplasty in Chronic Suppurative Otitis Media with Small Central Perforation

“…Similarly there was no effect of age of the patient on the pre operative hearing loss or the hearing gain following surgery in our study. In a study conducted by Debnath and Khanna [9], the average age of the study group was 35 years which is comparable with our study.…”

Otoendoscopic management of small to medium sized tympanic membrane perforation

“…5 In study a another comparison of chemical cautery versus fat myringoplasty by Debnath, closure results were found to be comparable with an average success rate of 68%.In our study the results were 55% with chemical cautry only and 88% with combination of chemical cautry and fat myringoplasty. 6 The less success rates are explained as chemical cauterisation nedded repeated cycles and less no of cases in study group. The perichondrium graft success rate in myringoplasty was reported as 71%-96% in the literature review of el-Guindy et al, Yadav et al 7,8 A otoendoscopic tympanoplsty fulfills the criteria of minimally invasive surgery with least trauma to normal tissue and that almost excludes pre and postoperative complications.…”

Closure of Small Central Perforations of Tympanic Membrane With Gelfilm Patch and Application of Platelet Rich Plasma Versus Chemical Cauterization: A Comparative Study

“…[5] In a recent study on comparison of chemical cautery versus fat myringoplasty by Debnath in November 2013, closure results were found to be comparable with an average success rate of 68%. [6] Evolution of Patching Technique for Tympanic Membrane Closure In paper patch myringoplasty a paper disk, moistened on one side with a solution of 1% phenol in glycerine to make it adherent, is introduced with a small alligator-type forceps and teased into place with a tiny blunt ear hook or ring. [7] After a week to 10 days, the patch migrates along with the exfoliated skin toward the external auditory meatus.…”
