Abstract

  Background: Otitis externa is an inflammation of the outer ear canal, with or without infection, and can occur at any age, in which fungal otitis externa is a relatively common disease, especially water. We have a hot and humid climate like ours. Objective: To survey the clinical features, laboratory findings, and treatment outcomes of external otomycosis. Materials and method: Observational, descriptive, and longitudinal study with clinical intervention. Research location: Ear, Nose, and Throat Department of C Hospital in Da Nang. Patients: 42 patients with external otomycosis from September 2017 to September 2019. Results: The disease was most common in individuals over 60 years of age, accounting for 61.9%. There was no significant difference in the incidence of the disease between genders. The two main symptoms of the disease was itchy ears and tinnitus. From the results of direct examination of ear discharge, the highest percentage was attributed to filamentous fungi (73%). From the results of the culture, the most common fungus was Aspergillus (88.2%). Only 15 cases (29.5%) grew bacteria, most commonly Staphylococcus aureus (11.8%) and methicillin-resistant Staphylococcus aureus (11.8%). The treatment response rate was 90.2% and the failure rate was 9.8%. The average duration of antifungal therapy was 11.4 ± 2.4 days. Conclusions:  The in-situ antifungal treatment method for the treatment of external otitis caused by fungi is an effective treatment method and has been proven by many research studies.
