Tinnitus in One Ear: When Unilateral Tinnitus Needs Further Evaluation

Tinnitus that is heard mainly or only in one ear is called unilateral tinnitus. It can have benign explanations, but the one-sided pattern is clinically useful information and should not simply be dismissed without appropriate assessment.

Possible explanations

One-sided tinnitus may occur with asymmetric hearing loss, ear blockage or middle-ear conditions, previous noise exposure, jaw or neck influences, and less commonly other ear or neurological conditions. The tinnitus sound alone cannot identify the cause.

When additional review is especially important

• Sudden or rapidly changing hearing loss

• Marked difference in hearing between the ears

• Persistent dizziness, imbalance or neurological symptoms

• Pulsatile tinnitus or other unusual ear symptoms

An audiological assessment can document hearing symmetry and help determine whether ENT or medical evaluation is warranted. Sudden hearing loss should be treated as time-sensitive and assessed urgently.
