In most cases of pars tensa cholesteatoma, transcanal endoscopic ear surgery (TEES) can be performed with a clear view. Since September 2015, we have selected TEES as the basic procedure for pars tensa cholesteatoma. We classified 115 ears treated with initial surgery for pars tensa cholesteatoma between January 2010 and March 2020 at the Department of Otolaryngology, Kurume University Hospital, based on Japanese Otological Society staging system for middle ear cholesteatoma (2015). The selection of the surgical method, hearing outcomes, and the rate of recurrence due to residual cholesteatoma and reformation of cholesteatoma were determined. The surgical outcomes of the pre-TEES (n=61) and post-TEES (n=54) groups were compared. In the post-TEES group, 74% of the patients underwent surgery with TEES alone. There was a trend toward improved hearing success after the introduction of TEES. The rates of residual recurrence and reformation were similar in the pre-TEES and post-TEES groups.
