Acute *Staphylococcus aureus* otitis externa is a rapid-onset, bacterial infection of the skin and subcutaneous tissues lining the external auditory canal caused by *Staphylococcus aureus* Pathophysiologically, disruption of the cerumen barrier and canal epithelium allows *S. aureus* proliferation, inciting acute local inflammation

It can affect patients of all ages, occurring frequently in children, adolescents, and adults following moisture exposure or local mechanical epithelial trauma The clinical state is characterized by severe otalgia, marked tenderness upon manipulation of the tragus or auricle, pruritus, canal erythema, luminal edema, and purulent otorrhea, occasionally progressing to localized furunculosis
