Overview of otitis externa

Otitis externa, also known as swimmer's ear, is an inflammatory condition affecting the outer ear canal between the pinna and the eardrum. According to Dr. Olga Papadopoulou, an ENT Director at Metropolitan Hospital, the condition is typically caused by bacterial or fungal infections. Inflammation occurs when pathogens enter the skin of the ear canal, often through small abrasions. Risk factors include prolonged exposure to moisture, excessive sweating, ear trauma, and underlying skin conditions like dermatitis. The term swimmer's ear reflects how trapped water after swimming can create a favorable environment for infection. This condition can affect individuals of all ages, including adults, children, and infants. Proper management and preventive measures are essential for effective treatment and avoiding recurrence.
