External Acoustic Meatus Cholesteatoma: A Systematic Literature Review.
Key Words: Cholesteatoma, External Acoustic Meatus, Symptomatology.
External acoustic meatus cholesteatoma (EAMC) is the rarest form of cholesteatoma, therefore its characteristics are not still completely clarified. This paper develops a systematic review of EAMC in the last five years, with the purpose to identify the main clinical manifestations, symptoms and incidence in the general population, by a critical analysis of papers from the PubMed database, which meet the inclusion criteria established – english language papers, with full text available in MEDLINE, using the descriptors “cholesteatoma” and “external acoustic meatus” and the boolean operator “and”. The chosen publications reported that the most recurrent clinical manifestations of EAMC are otalgia and otorrhea, but many patients are asymptomatic. Furthermore, an equivalent incidence was observed in both genders, being itinerant in elderly people. The therapeutic choice varies according to stage of the injury.
