ABSTRACT

Objective: To analyze the variables considered responsible of secondary lesions to the extraction of foreign bodies in the external auditory canal.
Patients and methods: This is a transversal study conducted in an Otolaryngology service at a third level care hospital, during a period of two months.
Results: A 20 patients-group with foreign bodies in the external auditory canal was studied, 12 (60%) of them were male, with a mean age of 19.1 years, 40% (8) right and 60% (12) left. The kind of foreign body was observed, the average of evolution time was 109 hours, 12 (60%) of the patients had previous manipulation (extraction techniques). the most common lesions were: external auditory canal laceration and hyperemia and tympanic membrane de-epithelization.
Conclusions: The variables that are commonly considered factors in the development of lesions in external auditory canal after a foreign body extraction have no real statistic relation. We suggest that in order to prevent this kind of lesions the following variables must be considered: qualified personal and suitable material and space.
