The perception of sound — ringing, buzzing, hissing, or pulsing — in the ear without an external source. One of the most common ENT complaints and a symptom that can point to several different underlying conditions.
Medical definition
Tinnitus (from the Latin tinnire, to ring) is an auditory phantom — a sound perceived in the ear or head without a corresponding external acoustic stimulus. It is classified as subjective (only the patient hears it) or objective (also audible to the examiner with a stethoscope). Subjective tinnitus is by far the more common form and arises from aberrant neural activity in the auditory pathway, usually secondary to cochlear damage. Objective tinnitus is rare and typically has a vascular cause (pulsatile tinnitus synchronous with the heartbeat) or a muscular cause (palatal myoclonus). By character, tinnitus may be continuous, intermittent, unilateral, or bilateral. By pitch, it varies from low rumbling to high-pitched whistle. Its intensity rarely exceeds ambient background noise on objective measurement, but its subjective impact can be severely disabling.
Why it matters for vertigo
Tinnitus is a symptom, not a diagnosis. Its character and laterality provide diagnostic clues that directly affect the vestibular workup. Unilateral low-frequency tinnitus that fluctuates with hearing changes and vertigo is the classic Meniere’s disease triad. Unilateral high-pitched tinnitus with progressive hearing loss and no vertigo raises concern for vestibular schwannoma. Pulsatile tinnitus — heartbeat-synchronous — needs vascular imaging, not just an audiogram. Bilateral high-frequency tinnitus in a patient with noise exposure history indicates noise-induced cochlear damage. And tinnitus that started alongside sudden unilateral hearing loss is an ENT emergency: sudden sensorineural hearing loss with tinnitus needs steroid treatment within 24 to 48 hours, not a wait-and-see approach.
Where I see this in clinic
Tinnitus is one of the most common reasons patients contact me, both for in-person visits and online consultations. The first thing I establish is laterality and character. Bilateral steady high-pitched tinnitus in someone over 50 with symmetric hearing loss is usually age-related cochlear change — manageable but not reversible. Unilateral tinnitus, especially with any hearing asymmetry, gets a full audiogram and, if asymmetric, an MRI of the internal acoustic meati to rule out a vestibular schwannoma. I am direct with patients: most tinnitus will not go away completely, but habituation is achievable, and for many patients that is the realistic goal. The cases I treat urgently are pulsatile tinnitus (vascular workup the same week) and sudden onset tinnitus with hearing loss (steroids within 24 hours).

Aural fullness – often accompanies tinnitus in Meniere’s disease. Nystagmus – present during Meniere’s attacks alongside tinnitus. Bilateral vestibulopathy – tinnitus may be absent, helping distinguish it from bilateral Meniere’s. Oscillopsia – may coexist with tinnitus in active vestibular disease.
