Initially the discharge may be odorless but can progress into a foul smelling odor.n offensive smelling odor from the ear is often assumed to be a sign of infection but there are a few other non-infectious causes that also need to be considered. The odor may be associated with an ear discharge, ear wax or something even more serious. Causes of a Smelly Ear Odor. Hygiene.
Ear wax is 20 to 50 percent fat, and it coats the ear canal to moisturize it, fight off infection, and help keep dust, dirt, and other debris from getting deep inside your ear. Most people make enough ear wax, but if you have too little ear wax, your ears can become dry, itchy, and prone to infection. Once ear wax has served its purpose, it eventually migrates from your ear canal to the opening of your ear, where it normally dries up and falls out of your ear.
