Abstract
Conclusions: Scutum erosion has an important role in the diagnosis of attic cholesteatoma, but it does not appear in other types of cholesteatoma in temporal bone. Without scutum erosion, the existence of cholesteatoma cannot be excluded. Objective: To evaluate the value of scutum erosion in the diagnosis of cholesteatoma in temporal bone and its limitations. Subjects and methods: CT scanning and otoscopy were used in all patients who were suspected of developing, or were probably diagnosed with, cholesteatoma in temporal bone. The condition of the scutum was recorded by otoscopy, CT scanning and surgical findings in all patients with cholesteatomas. Results: Scutum erosion can be shown in attic retraction with cholesteatoma at an early stage, but not in marginal perforation or with posterior retraction with cholesteatoma, or in central perforation or intact tympanic membrane with cholesteatoma, even in relatively late stages.
