摘要

<正>儿童先天性中耳珍珠瘤是儿童先天性中耳胆脂瘤的一种，源自于先天遗留在中耳且无法排出的上皮组织，抑或产生于羊水里的鳞状上皮，或是由于儿童时期鼓膜急性感染造成鼓膜与听骨相贴，鼓膜上皮组织进入中耳听骨链周围发展而来~([1-3])，类似珍珠，故称为珍珠瘤，具有完整的包膜囊壁，且囊壁表面多伴发新生血管~([4,5])。儿童先天性中耳珍珠瘤相对少见，患病率约为3/100 000，占所有儿童耳部胆脂瘤的4%，平均患病年龄4～5岁，男性的发病率是女性的1.1倍~([6,7])，早期症状隐匿，很难发现。本文通过分析一例幼儿先天性中耳珍珠瘤病例的临床资料，希望对儿童先天性中耳珍珠瘤的诊疗有所帮助。
