Abstract
OBJECTIVE: To compare surgical outcomes of transcanal endoscopic ear surgery (TEES) for congenital ossicular anomalies with those of conventional microscopic surgery.
STUDY DESIGN: Retrospective case review.
SETTING: Tertiary referral academic center.
SUBJECTS AND METHODS: From March 2012 to November 2018, 42 consecutive ears in 40 patients with congenital ossicular anomaly who underwent ossiculoplasty or stapes surgery using either ear endoscopes (TEES group) or an operating microscope (microscopic group) were included. Postoperative audiometric results, operation time, switch of approach, and complications were compared between the 2 groups.
RESULTS: Twenty-four ears (66.1%) were in the microscopic group and 18 ears (33.9%) were in the TEES group. The mean (SD) preoperative air-bone gap was 31.8 (10.0) dB in the microscopic group and 35.2 (11.1) dB in the TEES group. The mean (SD) postoperative air-bone gap was 7.4 (6.5) dB in the microscopic group and 5.6 (5.0) dB in the TEES group. The differences in the preoperative and postoperative air-bone gaps between the 2 groups were not statistically significant (P = .316 and P = .412, respectively). Average operation time in the TEES group was 24.6 minutes shorter than that in the microscopic group, which was statistically significant (P = .019). None of patients in the TEES group did require a switch of approach. There was no significant difference in complication incidence between the 2 groups.
CONCLUSIONS: TEES for congenital ossicular anomaly has comparable audiometric results and complication rates to conventional microscopic surgery. TEES appears to have the advantages of shorter operation times.
