“…Since then, the demonstrated incidence of sensitivity to neomycin in patients with chronic external otitis has risen progressively from an incidence of around 8% in the early 1970s to 35% in the early 1990s [46][47][48][49]. Topical sensitization may manifest as a fairly florid and obvious reaction with erythematous and vesicular eruption involving the lobule, entire auricle, and sometimes the surrounding tissues.…”

The bacterial cause of external otitis was first identified during World War II, and our understanding of this condition and its management has been relatively static until recently. The use of fluoroquinolones to treat pseudomonas infections has focused attention on topical therapy for external otitis and single-drug oral therapy for skull-base osteomyelitis, which arises as a complication of external otitis. This article reviews the pathophysiology of external otitis, outlines management options with special attention to topical therapy, and presents management options for skull-base osteomyelitis.

Chronic otitis externa is a common condition, which is usually successfully treated by topical medications and aural toilet. In cases that persist despite conventional treatment, a diagnosis of allergic otitis externa should be considered. Sensitization to otic medications (secondary contact otitis) is not uncommon. Topical aminoglycosides are the most common sensitizers although many components of topical preparations can cause sensitization. Patients who may have developed allergic otitis externa should undergo patch testing. Otolaryngologists should consider using topical antibiotics with a low allergenic potential and avoiding neomycin when treating patients with otitis externa. Primary contact otitis may occur to metals used in earrings and also to hearing aid moulds. Treatment of both primary and secondary contact otitis consists of identifying the allergen, avoiding further contact and use of simple preparations avoiding common sensitizers.
