Success is a matter of experience: type 1 tympanoplasty : influencing factors on type 1 tympanoplasty.
Our objective was to identify the factors that could influence the success rate of type 1 tympanoplasty in a tertiary care centre where both residents and senior surgeons perform this operation. Six hundred and seven patients who had been performed type 1 tympanoplasty as a primary otologic surgery between January 1997 and December 2004 were retrospectively chart reviewed. The patients had intact and mobile ossicular chain peroperatively. Patients with any other macroscopic otologic pathology like cholesteatoma, granulation in the middle ear and osteitis in mastoid cells were excluded from the study. Dry ear, intact and mobile tympanic membrane, improvement of the hearing by at least 10 dB and air-bone gap less than 25 dB were accepted as success criteria after 12 months of follow-up period. Chi-square test was used for statistical comparison of the different influencing factors. The male gender, younger age, smaller-sized perforations and experience of the surgeon were stated as good prognostic factors due to statistical evaluation. Afterwards the data of the study group was reanalysed in order to decide the cases for the residents. Finally, it was observed that seniors had better results in cases with perforations greater than 50%, dry ears and patients older than 16 years. In training and research clinics where both residents and senior surgeons perform type 1 tympanoplasty, the rate of success can be enhanced if patients with perforations greater than 50%, dry ears and patients older than 16 years are operated by the senior surgeons. The reason for this is that these groups have the overall worse results and should by argument be done by senior surgeons.
