Objective To compare closure rates and hearing outcomes of microscopic and endoscopic tympanoplasty in pediatric patients. Study Design Retrospective chart review. Setting Tertiary university medical center. Patients Pediatric patients who underwent tympanoplasty surgery by a fellowship-trained neurotologist between 2010 and 2019 with a minimum of 2 months of follow-up, a tympanic membrane perforation, and no preoperative cholesteatoma. Interventions Transcanal endoscopic tympanoplasty or microscopic tympanoplasty (MT) surgery. Main Outcome Measures The primary outcome is postoperative closure of the tympanic membrane perforation, assessed using otomicroscopy at the last follow-up appointment. Secondary outcomes include operative time and changes in the air-bone gap (ABG) and pure-tone average (PTA). Results Two hundred eleven tympanoplasty operations were analyzed: 121 in the transcanal endoscopic ear surgery (TEES) group and 90 in the MT group. Tympanic membrane closure rates were no different between the two groups (TEES, 82.6%; MT, 88.9%; p = 0.24), and no significant association was found on multivariable analysis (TEES: odds ratio, 0.8; p = 0.61). Both groups showed improvements in the 4-month PTA and ABG and the 12-month PTA, but the 12-month ABG only improved in the TEES group (p < 0.01). The TEES group had a shorter average operative time (109.8 versus 123.5 min; p = 0.03) and less need for a postauricular incision (2.5% versus 93.3%; p < 0.01). Conclusion In pediatric tympanoplasty, TEES gives similar membrane closure and hearing outcomes as the microscopic technique, with less operative time and less need for a postauricular incision.
