Ear Infections. An infection of the outer and middle ear (otitis externa and media) is the most common cause of a smelly ear discharge (otorrhea). A purulent discharge may appear white to pale yellow initially. 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.
