The author reports a recently recognised physical examination finding, otoscope fogging, for perforated tympanic membrane. Otoscope fogging is defined as condensation forming in the view field of the otoscope while inspecting the ear. In the setting of occult perforation secondary to the inability to visualise the entire tympanic membrane, otoscope fogging may provide the clinician with valuable information since medical management may differ if perforation is present.
作者报告了一项最近才被认识到的体格检查发现——耳镜模糊，这一现象见于鼓膜穿孔。耳镜模糊的定义为在检查耳朵时，耳镜视野中形成的冷凝现象。在因无法看到完整鼓膜而存在隐匿性穿孔的情况下，耳镜模糊可能会为临床医生提供有价值的信息，因为如果存在穿孔，医疗处理可能会有所不同。
