ABSTRACT
The objective of this study was to determine the influence of size of central tympanic membrane perforation on outcome ofmyringoplasty. Descriptive-Interventional Study. ENT Department PNS SHIFA Karachi. The study was completed in seventeen months from 22nd August 2009 to 22nd Jan 2010. The study consists of 60 cases. Non-Probability Convenience Sampling. After obtaining informed consent sixty patients undergoing myringoplasty at PNS SHIFA Karachi during the study period fitting the inclusion criteria were selected. Patients were examined and the size of tympanic membrane perforation was recorded. Perforation up to two quadrents was labeled as small perforation, three quadrents as large perforation and four quadrents labeled as subtotal perforation. The patients were managed by myringoplasty using Endaural incision with underlay technique to place the graft harvested from Temporalis fascia under General Anesthesia. All surgeries were performed by second author [senior consultant surgeon]. After undergoing myringoplasty patients were followed in ENT OPD on 2nd week to check the status of ear after removal of BIPP and eight weekly interval to check complete healing of graft for final result.:After 8wks 100% [n=20] patients with small perforation, 85% [n=17] with large perforation and 60% [n=12] with subtotal perforation had perfect healing and graft was intact. Smaller perforations have a greater chance of healing after surgery
