Laporan Kasus: Otitis Eksterna

Abstract

Otitis externa (OE) is a disease that is often encountered in otorhinolaryngology practice. OE is defined as inflammation of the external acoustic canal (KAE) and can extend beyond the KAE to involve the pinna and surrounding soft tissue. OE can occur by several factors, namely the environment, a decrease in skin pH, and a person's habits such as picking their ears, which can cause trauma. OE is common worldwide, with a higher incidence in tropical regions than in temperate regions due to higher temperatures and humidity. OE can be caused by bacterial, fungal or viral infections. More than 90% of cases of otitis externa are caused by bacteria, most commonly Pseudomonas aeruginosa (22-62%) and Staphylococcus aureus. Based on its onset, OE is called acute if the symptoms experienced last less than 6 weeks and chronic if the symptoms experienced are more than 3 months. The principle of managing OE is to clean the KAE (aural toilet), use topical antiseptics and antimicrobials as well as adequate analgesics. In diffuse OE, the use of tampons containing antibiotics is recommended.
