PURPOSE

Type I tympanoplasty is one of the first operations to be performed by ear surgeons in training and is increasingly performed using the endoscopic technique. The aim of the present study is to assess and compare the learning curve for type I tympanoplasties between a microscopically trained and endoscopic native ear surgeon. We hypothesize comparable learning curves between the two surgeons regardless of previous microscopic experience.

METHODS

Retrospective analysis and comparison of the 25 first consecutive cases of type I tympanoplasty performed by a microscopically trained ear surgeon (MTES) and a native endoscopic ear surgeon (NEES).

RESULTS

Mean duration of surgery in MTES and NEES groups was 54 ± 12.3 min and 55.6 ± 17.5 min, respectively. Both surgeons achieved a reduction of the surgery duration over time with statistically significant reduction from the first five cases to the last five cases in both groups. Graft intake rate was 92% after 3 months. Preoperative and postoperative PTA revealed a mean improvement of air bone gap (ABG) of 11.5 ± 7.1 dB HL in MTES group versus 9.3 ± 8.5 dB HL in NEES group, whereby the difference between the two groups was not statistically significant.

CONCLUSION

Endoscopic type I tympanoplasty shows comparable results and learning curves in two beginning endoscopic ear surgeons independent of the previous microscopic experience. We recommend if available the parallel learning of both techniques.
