Acute Pseudomonas aeruginosa otitis externa

Acute *Pseudomonas aeruginosa* otitis externa is a rapid-onset bacterial infection causing diffuse inflammation of the external auditory canal and auricle It most frequently develops in children and adults following water exposure, local canal trauma, or elevated environmental humidity, which disrupt the protective lipid-rich cerumen barrier and facilitate colonization by the Gram-negative opportunistic pathogen *Pseudomonas aeruginosa*

It most frequently develops in children and adults following water exposure, local canal trauma, or elevated environmental humidity, which disrupt the protective lipid-rich cerumen barrier and facilitate colonization by the Gram-negative opportunistic pathogen *Pseudomonas aeruginosa*

Defining clinical features include severe otalgia disproportionately exacerbated by manipulation of the tragus or pinna, canal erythema, pronounced edema that may occlude the canal, pruritus, purulent or seropurulent otorrhea, and occasional conductive hearing loss
