Brief description

This is an infection of the external ear canal or a non-infective inflammation of the external ear canal. It does not involve the middle ear or the inner ear.  It will most often be unilateral.

Confirming the diagnosis

The diagnosis is made on clinical grounds and can be made by the treating GP.

The relevant medical specialist is an ENT surgeon

# Non-SOP condition

Clinical onset

This condition can be a one-off acute infection, or there can be recurrent discrete episodes, or there can be an underlying problem resulting in a chronic or relapsing course.  In the absence of an underlying chronic cause each episode will represent a new clinical onset.  For chronic or relapsing otitis externa, the clinical onset will be the first episode triggered by the underlying problem.

Clinical worsening

Clinical worsening will generally only be relevant for chronic or relapsing otitis exterma.
