Ménière's disease turn, is strongly associated with developing MD, but not everyone with EH develops MD: "The relationship between endolymphatic hydrops and Meniere's disease is not a simple, ideal correlation." Additionally, in fully developed MD the balance system (vestibular system) and the hearing system (cochlea) of the inner ear are affected, but there are cases where EH affects only one of the two systems strong enough to cause symptoms. The corresponding subtypes of MD are called "vestibular MD", showing symptoms of vertigo, and "cochlear MD", showing symptoms of hearing loss and tinnitus.

The most common cause of cauliflower ear is blunt trauma to the ear leading to a hematoma which, if left untreated, eventually heals to give the distinct appearance of cauliflower ear. The structure of the ear is supported by a cartilaginous scaffold consisting of
