Scope
The Bottom Line
- Otitis externa can cause ear-canal pain, itch, discharge and tenderness with movement of the tragus or pinna.
- Examine the canal and tympanic membrane where visible and distinguish canal infection from otitis media, foreign body and perforation.
- Cleaning visible debris and delivering suitable topical treatment to the canal are central local-pathway actions.
- Keep the ear dry during treatment and address swimming, instrumentation or skin disease that contributed.
Practical clinical workflow
Safety boundaries and escalation
- Severe nocturnal pain, granulation, cranial-nerve change or invasive infection risk in diabetes or immune compromise requires urgent ENT assessment.
- Do not use a potentially ototoxic preparation when the tympanic membrane is not intact or cannot be assessed without checking current product guidance.
