In this study, we aimed to examine the usefulness and validity of TEES for ossicular chain disruption in the early stages of its introduction in our institution.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>TEES was performed on 11 ears (10 with congenital ossicular chain discontinuity and 1 with traumatic ossicular chain dislocation), and MES was performed with a retroauricular incision on 18 ears (6 with congenital ossicular chain discontinuity and 12 with traumatic ossicular chain dislocation) in a tertiary referral center. Postoperative hearing results, operative times, and postoperative hospital length of stay were retrospectively reviewed. The Mann\u2013Whitney <jats:italic>U<\/jats:italic> test and Fisher\u2019s exact test was performed to compare variables between the TEES and MES groups. Pre- and postoperative air- and bone-conduction thresholds and the air\u2013bone gap of each group were compared using the Wilcoxon signed-rank test. The Mann\u2013Whitney <jats:italic>U<\/jats:italic> test and Wilcoxon signed-rank was performed to compare the pre- and postoperative air\u2013bone gaps between the diagnoses.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>No significant differences in the postoperative air-conduction thresholds, bone-conduction thresholds, air\u2013bone gaps, or incidence of air\u2013bone gap\u2009\u2264\u200920\u00a0dB were observed between the TEES and MES groups. The air-conduction thresholds and air\u2013bone gaps of the TEES group significantly improved postoperatively. The air-conduction thresholds and air\u2013bone gaps of the MES group also significantly improved postoperatively. No significant difference was observed in the operative times between the groups (TEES group: median, 80\u00a0min; MES group: median, 85.5\u00a0min). The TEES group had a significantly shorter postoperative hospital stay (median, 2\u00a0days) than the MES group (median, 7.5\u00a0days).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>TEES was considered appropriate for the treatment of ossicular chain disruption, even immediately after its introduction at our institution.
