Approach to otitis externa in Australian general practice

Acute otitis externa (AOE) is an inflammatory condition of the outer ear seen in Australian general practice and is prevalent in tropical climates like North Queensland.

This article aims to delineate key facets of AOE, identify high-risk populations and propose a streamlined management approach aligned with the American Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) guideline, emphasising the role of primary care in optimal patient care.

Outlined within this article are key elements of AOE, from anatomy to risk factors, examination, diagnosis, differentials, management, prevention and indications for referral. Emphasis is placed on topical antibiotic use, drug delivery techniques and recognising refractory cases. The importance of early intervention is highlighted to prevent complications, particularly in at-risk populations, aligned with AAO-HNS guidelines and enhancing general practice's role in mitigating AOE-related complications.
