				        	BACKGROUND AND OBJECTIVES: There is no consensus on the prognostic factors regarding pos-toperative recurrence after myringoplasty. In this study, we investigated the preoperative clinical findings and postoperative results after primary myringoplasty and compared them with those of revision myringoplasty. SUBJECTS AND METHOD: Computerized database of 861 clinical records of last 20 years were analyzed retrospectively for the subjects who underwent myringoplasty at the Department of Otolaryngology, University of Korea. All the surgeries were done under general or local anesthesia by senior surgeons. Primary and revision cases of myringoplasty or type 1 tympanoplasty followed up at least for longer than 3 months were only included in the study. Those other cases of tympanoplasty types, concomitant ossiculoplasty and/or mastoidectomy, or those with the presence of cholesteatoma and those that required repair during exploratory tympanotomy were excluded. RESULTS: 535 primary and 101 revision cases have met our inclusion criteria. Overall, in this study, the failure rates of primary and revision myringoplasty were 11.02% and 5.94%, respectively. Significantly different among the prognostic factors were such as sex, age, anesthesia, surgical approach, the presence of otorreha, size of eardrum perforation, external auditory canal narrowing, valsalva test, degree of pneumatization, graft materials, tympanoplasty type, previous mastoidectomy, the presence of bilateral otitis media influencing on myringoplasty revision, and the presence of otorrhea and sclerotic type of mastoid pneumatization. CONCLUSION: Among various prognostic factors of myringoplasty, poor prognostic factors were preoperative otorrhea and poor pneumatization.
