Most cases of localised OE are self-limiting, although symptomatic relief in the form of analgesia and the application of warm heat may be helpful. Acute diffuse OE may also require simple analgesia, in addition to management of any aggravating or precipitating factors. Mild cases will often respond to topical acetic acid spray, but others may require a seven- to 14-day course of topical antibiotics with or without a topical steroid.There is no evidence supporting any one ingredient over another, so dosing frequency, cost, adverse effects and whether or not the eardrum is perforated should be considered when making a choice. 

If the ear canal is obstructed with earwax or debris, it may require cleaning before any topical preparations are used.

There are several self care measures that people with OE can take to aid recovery and reduce the risk of a recurrence. These include:

• Avoiding damage to the ear canal, by not using cotton buds for cleaning and seeking professional help if earwax needs removing
• Keeping the ears clean and dry by taking care during washing and avoiding waterbased activities for a week or so
• Keeping skin conditions such as eczema and psoriasis under control
• Using hypoallergenic earrings, hearing aids and ear plugs if sensitivity is an issue.
