tinnitus does not cause the face to droop but bells palsy can. the same virus that may have caused your tinnitus/ringing could be the same virus that is now cause some nerve problems in those facial muscles. many times this is a herpes simplex virus. i suggest that you see your medical provider right away about this droopy face since there are medications that can help.
does ringing in the ear cause the face to droop on one side? . im basically healthy and had ringing in the ear about 2 yrs ago due to a viral infection from a cold. i had a sore throat on the same side i took lipo-flavonoid and afte time the ringing stopped. i made the mistake and stopped taking it and receintly the ringing came back. several days later the same side of my face drooped. i am able to blink both eyes. some watering occurs from that eye if wind hits it.
