Myringosclerosis is characterized by hyaline changes of the lamina propria of the tympanic membrane. Experimental studies have used otomicroscopy or histology to evaluate myringosclerosis in animals, but they do not correlate precisely these two methods.
The present study evaluates the accuracy of otomicroscopy in the diagnosis of myringosclerosis in rats.
Experimental.
Myringosclerosis was induced by transtympanic inoculation of Streptococcus pneumoniae in 25 Wistar rats, which were examined weekly through otomicroscopy and sacrificed after eight weeks for histologic study of their tympanic membranes.
From the comparison of the otomicroscopic data in relation to the histologic findings, we could observe sensibility of 80% and specificity of 75% for the otomicroscopy.
Considering the results in this study, otomicroscopy did not represent a good method to evaluate myringosclerosis in this experimental model.
鼓膜硬化症的特征是鼓膜固有层的透明样改变。实验研究已使用耳显微镜检查或组织学来评估动物的鼓膜硬化症，但它们并未精确关联这两种方法。
本研究评估耳显微镜检查诊断大鼠鼓膜硬化症的准确性。
实验性研究。
通过经鼓膜接种肺炎链球菌在25只Wistar大鼠中诱发鼓膜硬化症，每周通过耳显微镜检查对其进行检查，并在八周后处死以对其鼓膜进行组织学研究。
通过将耳显微镜检查数据与组织学结果进行比较，我们观察到耳显微镜检查的敏感度为80%，特异度为75%。
考虑到本研究的结果，在该实验模型中，耳显微镜检查并非评估鼓膜硬化症的好方法。
