In order to provide a basis for meaningful exchange of information among those treating cholesteatoma, the Committee on Nomenclature of the Japan Otological Society (JOS) was appointed in 2004 to create a cholesteatoma staging system as simple as possible to use in clinical practice in Japan. Following the announcement of preliminary criteria for the staging of pars flaccida (attic) cholesteatoma in 2008, we proposed the 2010 JOS staging system for two major types of retraction pocket cholesteatoma, pars flaccida and pars tensa cholesteatoma. Since then, the JOS staging system has been widely used in clinical studies of cholesteatoma in Japan, allowing standardization in reporting of surgical outcomes based on the respective stages of cholesteatoma. We have recently expanded the range of cholesteatoma by adding cholesteatoma secondary to a tensa perforation and congenital cholesteatoma as the 2015 JOS staging system for middle ear cholesteatoma. Although further revisions may be required for universal acceptance of these criteria, we hope our staging system will open the way for international consensus on staging and classification of middle ear cholesteatoma in the near future.
为了为胆脂瘤治疗人员之间有意义的信息交流提供依据，日本耳科学会（JOS）命名委员会于2004年被任命，以创建一个尽可能简单的胆脂瘤分期系统，用于日本的临床实践。在2008年公布松弛部（上鼓室）胆脂瘤分期的初步标准后，我们提出了2010年JOS两种主要类型的内陷袋胆脂瘤、松弛部和紧张部胆脂瘤的分期系统。从那时起，JOS分期系统在日本胆脂瘤的临床研究中得到了广泛应用，从而能够根据胆脂瘤的各个阶段对手术结果报告进行标准化。最近，我们通过将紧张部穿孔继发胆脂瘤和先天性胆脂瘤纳入作为2015年JOS中耳胆脂瘤分期系统，扩大了胆脂瘤的范围。尽管可能需要进一步修订这些标准才能被普遍接受，但我们希望我们的分期系统将在不久的将来为中耳胆脂瘤分期和分类的国际共识开辟道路。
