Characterization of patients with diffuse acute otitis externa

Authors

Abstract

Introduction: diffuse acute otitis externa is an infectious process of the ear canal. It is characterized by earache that can worsen within a few hours and radiate to the temporomandibular and craniofacial regions. Auricular pain is intense, even if the area is gently manipulated.

Objective: to characterize patients with diffuse acute external otitis.

Methods: a cross-sectional descriptive observational study was carried out in 82 patients with diffuse acute external otitis, treated at the otorhinolaryngology service of the Provincial Hospital of Ciego de Ávila, from July 2016 to January 2017. Demographic variables (age, sex and place of origin) and microbiological variables (types of bacteria and antibiogram) were analyzed. Ethical precepts were met.

Results: patients from the urban area (62,20 %), from the group of 20 years and over (57,32 %), and males (52,44 %) predominated. The most identified germs were Staphylococcus aureus (39,02 %), and Pseudomonas aeruginosa (21,95 %). Chloramphenicol (34,15 %), ciprofloxacin (28,05 %) and gentamicin (25,61 %), in order of frequency, were the antibiotics with the greatest sensitivity to germs. Staphylococcus aureus responded better to chloramphenicol.

Conclusions: diffuse acute otitis externa was more frequent in men of urban origin, aged 20 years and over. Chloramphenicol was the most sensitive antibiotic. The most identified germ was Staphylococcus aureus; those affected by this showed a better response to antibiotic treatment. The therapeutic evidence provided by this study helps specialists make more effective decisions in clinical practice.
