Abstract

Loss of hearing is a national health problem. Many literatures has proven the effectiveness of fat graft myringoplasty and chemical cauterization in closure of small tympanic membrane perforation and improvement in hearing . In the present study we have made an attempt to compare the effectiveness of these procedures Methods: This is a prospective randomised comparative study conducted in 60 patients from September 2017 to march 2019 who attended ENT OPD of Indira Gandhi government hospital, Puducherry. These patients were subjected to a detailed history taking, examination of ear, nose, and throat and later were subjected to series of investigations and the audiological assessment of the hearing loss was documented. The patients were randomly divided into two groups consisting of 30 members each and the first group underwent fat graft myringoplasty and the second group underwent chemical cauterization under endoscopic guidance. Results: There was a successful closure of 90% perforations who underwent fat graft myringoplasty and 83.3% perforations with a mean of 3.6 applications who underwent chemical cauterization. After fat graft myringoplasty there was a hearing improvement of 10.99 decibel and air bone closure of 10.93 decibel. Chemical cauterization showed a hearing improvement of 9.87 db and air bone closure of 9.82 db. Statistical analysis was done and both the procedures were found to be equally effective in terms of closure of small perforation of tympanic membrane and postoperative hearing improvement.
