Endoscopic transcanal versus conventional microscopic tympanoplasty in treatment of anterior tympanic membrane perforations

To compare the surgical outcomes of endoscopic transcanal tympanoplasty (ETT) and conventional microscopic tympanoplasty (CMT) in repairing anterior tympanic membrane perforations (ATMPs).
We retrospectively analyzed the graft success rate, hearing outcomes, operative time, hospitalization period and complications in patients who underwent ETT and CMT between October 2015 and July 2018. In addition, the authors investigated whether anterior canal wall protrusion (ACWP) affects the graft success rate and operative time.
The graft success rates for ETT and CMT were 93.7% (30 out of 32 patients) and 91.4% (32 out of 35 patients), respectively (p = 0.640). There was no significant relationship between ACWP and graft success rates in either the endoscopic (p = 0.685) and microscopic (p = 0.894) group. The mean operative time was significantly shorter in the ETT group (37.2 ± 3.1 min) than in the CMT group (52.9 ± 9.2 min) (p < 0.001). Regarding operative time, there was no statistically significant difference between patients with and without ACWP (38.3 versus 36.3 min, respectively (p = 0.124)) in the ETT group. However, the mean operative time of patients with ACWP in the CMT group was significantly longer than patients without ACWP [62.3 versus 48.8 min, respectively (p < 0.001)].
ETT offering fewer complication rates and shorter duration of surgery may serve as a reasonable alternative to CMT in repairing ATMPs, with comparable graft success rates.
