220例鼓膜穿孔性质分析

Analysis on characters of 220 cases of tympani membrane perforated

通过对 220例鼓膜穿孔鉴定的回顾，得出外伤鼓膜穿孔与炎性鼓膜穿孔在性别、年龄、耳别、穿孔形状、部位、大小、听力丧失程度、愈合时间、穿孔原因以及附着物上均具有显著性或极显著性差异 ,且这种差异与其穿孔机制有很大相关性；在比较分析基础上还提出了两种穿孔的鉴别要点，这对于临床法医检案具有较好的参考价值。

cases of tympani membrane perforated were summarized retrospectively. The tympani membrane perforated of injury was different from otitis media's because they had marked or extreme marked difference in sex, age, ear distinction, shape, position, size, degree of hearing damaged, time of healing, cause of perforating and adhesive substance. This difference was relative to mechanism of tympani membrane perforated. The distinction gist of two sorts of tympani membrane perforated was expounded through comparison and analysis. It would be of great value to clinical forensic medical examination.
