ROLE OF MINIMAL INVASIVE PROCEDURES FAT GRAFT MYRINGOPLASTY AND TRICHLORACETIC ACID CAUTERIZATION IN CASE OF DRY SMALL CENTRAL TYMPANIC MEMBRANE PERFORATIONS

Background: Day care surgeries have now become an integral part of modern otolaryngology. Fat graft myringoplasty and trichloracetic acid cauterization are cost effective, safe minimal invasive procedures having a success rate comparable to that of conventional Tympanoplasty. Conventional Tympanoplasty is time consuming, has greater morbidity is costlier and require more days of absenteeism as compared to these two office procedures.                         

Material and methods: The study was carried out over a period of 2 years on 58 selected patients. All the selected patients were divided into two groups. Group A and Group B.Group A patients underwent fat graft myringoplasty and Group B patients underwent chemical myringoplasty by using trichloracetic acid cauterization.                                                                                              Results: On  Follow up after 3 month there was complete closure of perforation in in 26 out of 28 cases of group A and 26 out of 30 cases in group B. Comparisons of the results were done using Fisher Exact Test. The difference between the two results was statistically insignificant with a p value of 0.5532.This indicates that both the office procedures are equally effective. 

Conclusion: Both these procedures are minimally invasive, safe and cost effective procedures and have results comparable to conventional tympanoplasty.
