Middle ear cholesteatoma is an important and relatively common disorder which may have serious consequences.
The purpose was to conduct a retrospective study of the statistics of 1,146 middle ear surgical procedures for middle ear cholesteatoma in adults and children of low income living in distant areas from our city.
From 1962 to 1988 there were 1,146 surgeries for unilateral or bilateral cholesteatomas in children and adults, which were reviewed for the following criteria: total number of surgeries, sex, onset of the first symptoms, duration of the disease, the site of perforation, the cholesteatoma site, changes in the ossicular chain, the contralateral ear, bilateral cholesteatomas, the site of residual cholesteatoma, and complications.
Results are shown graphically on a pie chart.
The etiology of cholesteatomas remains unknown. Epidemiological and statistical data, surgical reports, and conclusions of experimental studies are welcome, as they may provide support for clarifying the pathogenesis of cholesteatoma. Our results were compared with internationally published papers. We found no published papers on the epidemiology of cholesteatoma in the Brazilian literature.
中耳胆脂瘤是一种重要且相对常见的疾病，可能会产生严重后果。
对居住在我们城市偏远地区的低收入成人和儿童的 1146 例中耳胆脂瘤中耳手术的统计数据进行回顾性研究。
1962 年至 1988 年，我们对单侧或双侧胆脂瘤的儿童和成人进行了 1146 次手术，根据以下标准对这些手术进行了回顾：手术总数、性别、首发症状出现时间、疾病持续时间、穿孔部位、胆脂瘤部位、听骨链变化、对侧耳、双侧胆脂瘤、残余胆脂瘤部位和并发症。
结果以饼图形式显示。
胆脂瘤的病因仍不清楚。流行病学和统计数据、手术报告和实验研究的结论是受欢迎的，因为它们可能为阐明胆脂瘤的发病机制提供支持。我们的结果与国际发表的论文进行了比较。我们没有在巴西文献中找到关于胆脂瘤流行病学的已发表论文。
