Unilateral and pulsatile tinnitus red flags

Essential points for quick revision.

!
Tinnitus can accompany an acute emergency

Sudden neurological signs, uncontrolled acute vestibular symptoms or high suicide risk changes the response from routine tinnitus assessment to immediate care.

Action: Refer immediately through neurological or stroke pathways for acute focal or uncontrolled vestibular features, and to crisis mental health services when suicide risk is high; recent sudden hearing loss requires assessment within twenty-four hours.

Synopsis

Use laterality, pulse synchrony, associated symptoms and distress to prioritise tinnitus referral and select appropriate investigation while offering useful support from first contact.

  • Ask whether the sound is unilateral, bilateral or perceived centrally.
  • Establish whether pulsation actually matches the heartbeat rather than simply sounding rhythmic.
  • Offer audiological assessment to people with tinnitus.

Key red flags

Tinnitus with new facial weakness, other significant neurological findings or acute uncontrolled vertigo needs immediate referral.
