Myringoplasty [Risk factors and the effect of post operative follow up on the outcome of success rate in Erbil / Kurdistan of Iraq

Abstract

Background and objective: The presence of a perforated tympanic membrane with intermittent discharge and hearing loss of conductive type are the indication for myringoplasty. The purpose of this study was to determine risk factors in candidates for myringoplasty and to evaluate the post operative myringoplasty success rate results in our local region in Erbil/Kurdistan, Iraq. The second objective is to appraise and assess the effect of close observation and post operative treatment and follow up on this result, to increase the success rate. Methods: A prospective study, randomly taken 68 patients with unilateral perforated tympanic membrane, who are candidates for myringoplasty; patients of different age groups ranging [16 -55] years old, of different gender 30 males and 38 females., having dry unilateral perforated tympanic membrane of more than 3 months, underwent myringoplasty [underlay] between may 2006 and April 2009 at Rizgary teaching Hospital. Measurement of the post operative results and outcome were depend on the take rate and the hearing level at the last follow up visit in different time postoperatively and with dry clean non infected operated ear. Results: Small, dry posterior perforation, with postauricular approach in well pneumatized mastoid and in well educated non-smoker patient with close observation post-operatively using BIPP has better success rate. The success rate increased from 72% in the 1st postoperative visit to 88% in the last postoperative visit. Conclusion:-To increase the success rate, its necessary to determine the factors that affect the success rate preoperatively, also close observation with meticulous toilet of the operated ear post-operatively using BIPP is necessary to increase the success rate.
