Fat Plug Myringoplasty Vs Trichloroacetic Acid Cauterization as Office Procedures for Managing Small Central Perforation

Introduction 
In a series of day care office procedures, techniques like fat plug myringoplasty and Trichloroacetic acid (TCA) cauterization are becoming increasingly popular for managing small central perforations now-a-days[Office1] . These are minor, cost effective procedures and have success rates that match success rates of conventional tympanoplasty[Office2] . The aim of this prospective randomized controlled trial, was to compare the effectiveness of fat plug myringoplasty and chemical cauterization in the management of small centrally located perforations of the pars tensa. 
Materials and Methods 
The study was carried out over a period of 2 years on 62 patients selected from ENT OPD in our tertiary health care setup of central India. All the selected patients were grouped into two using a random allocation software EPi Info7.1.1.14. Group A included those who underwent fat plug myringoplasty while group B were those who underwent TCA cauterization. 
Results 
At 6 months follow up there was closure of perforation in 29 out of 30(96.6%) patients of group A and 29 out of 32(91%) patients of group B. In both groups success was defined by closure of perforation. Comparison of results was done using Fisher Exact Test. The difference between the success rates of the two procedures was statistically insignificant with p value of 0.6624, indicating that both the office procedures are equally effective and can be used according to the needs of the patients. 
Conclusion 
These office procedures can revolutionize the protocol of tympanoplasty which has an obvious higher morbidity and more days of absenteeism as compared to these minor procedures.
