小儿耳鼓膜鼓室硬化症似为一种新生、退化和复原交织在一起的动态过程,与分泌性中耳炎有关。硬化病变只影响鼓膜紧张部,绝不累及松弛部,甚至也很少发生于鼓膜紧张部后上象限。病理改变不明显,由不规则的胶原组织增殖支配整个病理过程,还有透明变性和小块钙化。作者对90例腭裂小儿,其中单有腭裂者38例(18个男孩,20个女孩),有唇裂和腭裂者52例(39个男孩、13个女孩),年龄从几个月～15岁,随访观察7.8年,总计检查2,068次,平均每年检查3次,由训练有素的耳科医师以及作者施行小儿耳显微镜检查,证实鼓膜上有鼓室硬化病灶时,以精确的图象或拍摄照片记录下来,并对有鼓室硬化症的耳鼓膜作活检,活检输送到电镜室处理, Pediatric eardrum tympanosclerosis like a newborn, degeneration and recovery intertwined dynamic process, and secretory otitis media. Sclerosis lesions affect only the tympanic membrane tension, never involving the relaxation, and even rarely occurs in the tympanic membrane after the upper quadrant. Pathological changes are not obvious, by the proliferation of irregular collagen dominate the entire pathological process, as well as transparent degeneration and small calcifications. The author of 90 cases of cleft palate children, including cleft palate in 38 cases (18 boys, 20 girls), cleft lip and cleft palate in 52 cases (39 boys, 13 girls), aged from a few months to 15 years old, Follow-up observation 7.8 years, a total of 2,068 inspections, an average of three times a year, by a trained otologist and the author performed pediatric ear microscopy confirmed tympanic membrane lesions on the tympanic membrane, with accurate images or taking pictures recorded Down, and tympanic sclerosis tympanic membrane for biopsy, biopsy delivered to the electron microscope room treatment,
