(1) : The incidence of congenital cholesteatoma (CC) has rarely been discussed, particularly from a demographic viewpoint. Therefore, we conducted an epidemiological study of CC using local medical characteristics. (2) : The participants were 100 patients (101 ears) who underwent initial surgical treatment at university hospitals in two rural prefectures between 2006 and 2022. A total of 68% of the patients were males and 32% were females, with a median age of 5 years. We reviewed the medical records for the date of birth, date of surgery, stage of disease, and first symptoms of the disease. (3) : The total incidence of CC was calculated to be 26.44 per 100,000 births and tended to increase. No significant difference was found between the incidences in the two prefectures. The number of surgeries performed was higher in the second half of the study period. No difference in the stage of progress was observed based on age. (4) : The incidence of CC was estimated to be 26.44 per 100,000 newborn births. The number of patients with CC tended to increase; however, this can be attributed to an increase in the detection rate rather than the incidence.
(1)：先天性胆脂瘤（CC）的发病率很少被讨论，尤其是从人口统计学角度。因此，我们利用当地医疗特征对CC进行了一项流行病学研究。(2)：研究对象为2006年至2022年间在两个农村县的大学医院接受初次手术治疗的100例患者（101只耳朵）。患者中68%为男性，32%为女性，中位年龄为5岁。我们查阅了病历，以获取出生日期、手术日期、疾病分期和疾病的首发症状。(3)：CC的总发病率经计算为每10万例出生中有26.44例，且呈上升趋势。两个县的发病率之间未发现显著差异。在研究期的后半段进行的手术数量更多。未观察到基于年龄的病情进展阶段差异。(4)：CC的发病率估计为每10万例新生儿中有26.44例。CC患者的数量呈上升趋势；然而，这可能归因于检出率的增加而非发病率的上升。
