The Japan Otological Society (JOS) conducted a nationwide epidemiological survey of patients with middle ear cholesteatoma who underwent initial surgery in 2015, enrolling 1,787 patients at 74 facilities in Japan. In 2018, a follow-up survey was conducted on 1,456 cases at 49 facilities in Japan, with 1,060 cases examined for hearing prognosis and 1,084 cases examined for recidivism prognosis. The hearing improvement rate was 63.3%, and 152 patients (14.0%) were found to have a recidivism. In 2020, the JOS compiled terminologies related to tympanoplasty, which further detailed its optional procedures. Moreover, members of the JOS and others also examined the extent to which optional procedures are performed for each condition and surgery.
In this issue, a comparative study of the epidemiology, surgical procedure selection, optional procedures, and outcomes in pars flaccid cholesteatoma and pars tense cholesteatoma was conducted.
In the future, surgical procedure selection and the use of optional procedures will become more standardized depending on the degree of staging. In addition, the issues and prospects of middle ear cholesteatoma treatment in the near future will also be discussed.
