The learning curve for endoscopic tympanoplasties: a single-institution experience, in Birmingham, UK.

OBJECTIVE

This study aimed to assess whether increasing operative experience results in better surgical outcomes in endoscopic middle-ear surgery.

METHODS

A retrospective single-institution cohort study was performed. Patients underwent endoscopic tympanoplasty between May 2013 and April 2019 performed by the senior surgeon or a trainee surgeon under direct supervision from the senior surgeon. Following data collection, statistical analysis compared success rates between early (learning curve) surgical procedures and later (experienced) tympanoplasties.

RESULTS

In total, 157 patients (86 male, 71 female), with a mean age of 41.6 years, were included. The patients were followed up for an average of 43.2 weeks. The overall primary closure rate was 90.0 per cent.

CONCLUSION

This study demonstrates an early learning curve for endoscopic ear surgery that improves with surgical experience. Adoption of the endoscopic technique did not impair the success rates of tympanoplasty.
