Clinical Analysis of Secondary Acquired Cholesteatoma

Objectives: To retrospectively analyse the clinical features of secondary acquired cholesteatoma.

Methods: Seventeen patients (17 ears) who underwent surgery for secondary acquired cholesteatoma between January 2009 and December 2013 were studied. The parameters examined included the sex and age of the patients and the size of the tympanic membrane perforation.

Results: There was a significant correlation between secondary acquired cholesteatoma and sex (18% men, 82% women). Patients with secondary acquired cholesteatoma (average, 56 years) were significantly older than those with other acquired cholesteatomas (average, 42 years). There was a trend toward lower likelihood of improvement in older patients after surgery.

Conclusion: Secondary acquired cholesteatomas differ from other acquired cholesteatomas in terms of patient sex and age. Improvements in postoperative hearing are more likely in younger patients. In some cases, secondary acquired cholesteatoma was diagnosed during surgery for chronic otitis media; therefore, it is very important to consider this possibility.
