What causes tinnitus in one ear?

Tinnitus is merely an auditory illusion—not a disease itself, but rather a symptom. It often causes restlessness and mental distress. In severe cases, it may significantly impair daily life and work performance. So, what causes tinnitus in only one ear?

Causes of Unilateral Tinnitus

Unilateral tinnitus may result from conditions such as cerumen impaction or otitis media.

1. Cerumen Impaction: This may occur due to excessive cerumen (earwax) production or entry of dust or foreign particles into the external auditory canal, leading to cerumen accumulation and blockage of the canal. Symptoms include unilateral tinnitus, hearing loss, and ear pain. Prompt medical evaluation and removal are therefore essential.

2. Otitis Media: This condition may arise from bacterial infection or eustachian tube dysfunction. Patients commonly experience ear pain and hearing loss; they may also develop otorrhea and unilateral tinnitus. Timely treatment with antibiotics—such as cefuroxime axetil tablets or roxithromycin capsules—can help control local infection, alleviate tinnitus, and support recovery.

Tinnitus refers to the perception of abnormal sound in the absence of any external acoustic stimulus. If you perceive sounds such as chirping, buzzing, or hissing—either tonal or complex—within your ear, yet no corresponding environmental sound exists, this indicates that tinnitus is purely a subjective sensation. It may be transient or persistent.

If tinnitus is persistent—especially when accompanied by additional symptoms such as hearing loss, vertigo, or headache—prompt medical attention is crucial. Take care to protect your ears: avoid water entering the ear canal while washing your hair or face. We hope this information proves helpful. Wishing you good health and a joyful life!
