Ear canal obstruction (cerumen obstruction, foreign body).Dermatologic conditions such as eczema and psoriasis.Trauma or external devices (cotton swabs, earplugs, hearing aids).Swimming is one of the most common risk factors, and it increases the risk five times when compared to non-swimmers. Various factors can predispose patients to the development of OE.
Otitis externa can also occur as a polymicrobial infection, and rarely, it may result from a fungal infection such as Candida or Aspergillus. Pseudomonas aeruginosa and Staphylococcus aureus are the most common pathogens involved in otitis externa. It may be associated with allergies, eczema, and psoriasis. The most common cause of acute otitis externa is a bacterial infection. It is also known as swimmer's ear as it often occurs during the summer and in tropical climates and having retained water in the ears increases the risk for it. OE can be classified as acute (lasts less than 6 weeks) or chronic (lasts more than 3 months). In some cases, inflammation can extend to the outer ear, such as the pinna or tragus. Otitis externa (OE) is an inflammation, that can be either infectious or non-infectious, of the external auditory canal. Summarize the importance of prompt recognition of complications among interprofessional team members to improve outcomes for patients affected with otitis externa.Identify the most common complications of otitis externa.Outline the mainstay treatment for otitis externa.Review the typical signs and symptoms of otitis externa.This activity outlines the evaluation and management of otitis externa and highlights the role of the interprofessional team in the care of patients with this condition. OE can be classified as acute, lasting less than 6 weeks, or chronic which lasts more than 3 months.
