Otitis externa - Diagnosis 

Diagnosing otitis externa 

See your GP if you think you may have otitis externa. They will ask you about your symptoms and whether you use any items that are inserted into your ears, such as hearing aids or ear plugs.

Ear examination

Your GP may use an instrument that has a light at one end, known as an otoscope, to examine your outer ear (pinna) and your ear canal. They will check your ear for redness and inflammation (swelling).

During the examination, your GP may also check for flaky skin, any visible sign of a fungal infection and whether or not your eardrum (tympanic membrane) is perforated (has a hole in it).

Ear swab

If you have recurring episodes of otitis externa or if medication that you have previously been prescribed hasn't worked, your GP may take a sample from your ear using an ear swab. This will help determine whether your infection is bacterial or fungal so that the appropriate medication can be prescribed.
