What could cause sudden hearing loss in one ear?

Answer 1

Many drugs can cause temporary hearing loss..or intermittent hearing loss. Aspirin causes a ringing in the ears called tinnitus and various syndromes cause hearing loss such as Meniere's disease. Concussion, Allergies and ear infection are also culprits.

Answer 2

Sudden "total" deafness in one ear can be caused by tiny blood clots in the extremely tiny arteries of the inner ear. Seek attention within 24 hours for the best outcome. In most cases, the "cause" is unknown...it could be a combination of autoimmune disease, allergies, etc. Be certain to see a specialist in this 24 hour time period. Some emergency facilities will treat you with steroids, decongestants and tell you to see a specialist in "x amount" of days, but ENTs are the ones who specialize in the ear/nose/and throat....and timing is important if you have any chance of reversing the damage.

If both ears have sudden hearing loss which is not "total," the cause could be inner or middle ear infections, or perhaps a medication. Some drugs are ototoxic...toxic to the ear.

Answer 3

An ear infection could cause sudden hearing loss in only one ear.
