Quick Answer
Most tinnitus is benign, but neurological causes including vestibular schwannoma and vascular abnormalities require evaluation.

Tinnitus — the perception of ringing, buzzing, or hissing in the ears — is extremely common and usually arises from benign causes such as age-related hearing loss, noise exposure, or earwax impaction. However, a subset of tinnitus cases have neurological causes that require investigation rather than reassurance. Understanding when tinnitus may signal a neurological condition helps guide appropriate evaluation.
Common tinnitus is typically bilateral, steady, and associated with hearing changes. Neurological tinnitus has features that raise concern: unilateral tinnitus (one ear only), pulsatile tinnitus (a rhythmic sound synchronous with the heartbeat), tinnitus accompanied by hearing loss that is sudden or progressive, or tinnitus with neurological symptoms such as facial weakness, imbalance, or dizziness.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for dizziness.
Vestibular schwannoma (acoustic neuroma) is the most commonly feared neurological cause of tinnitus. This benign tumour arises from the vestibular nerve and typically presents with unilateral sensorineural hearing loss and tinnitus. As it grows, it may cause dizziness, imbalance, and eventually facial numbness or weakness if the facial nerve is compressed. MRI of the internal auditory canals with gadolinium contrast is the investigation of choice when vestibular schwannoma is suspected. Early detection allows monitoring or treatment planning before significant growth.
Pulsatile tinnitus — a whooshing or thumping sound that matches the heartbeat — may indicate vascular abnormalities such as arteriovenous malformations, dural arteriovenous fistulas, or venous sinus stenosis. These conditions require vascular imaging (MRA or MRV) and specialist evaluation. Unlike common tinnitus, pulsatile tinnitus is often objective (the examiner can hear it with a stethoscope) and warrants prompt investigation.
Medication-induced tinnitus is another neurological consideration. High-dose aspirin, certain antibiotics (aminoglycosides), loop diuretics, and some chemotherapy agents can damage the cochlea or auditory nerve. When tinnitus develops after starting a new medication, the prescribing clinician should be informed. In some cases, dose adjustment or substitution reduces the tinnitus.
When to investigate: Unilateral tinnitus, pulsatile tinnitus, tinnitus with progressive hearing loss, tinnitus with neurological symptoms (facial weakness, severe dizziness, imbalance), or tinnitus that is new and persistent should prompt neurological evaluation rather than watchful waiting. Dr. Jitendra Prasad Yadav (NMC 8029) evaluates tinnitus at Kathmandu Neurology Clinic & Cognitive Center (Durbar Marg, Opposite of Yak & Yeti Hotel) with detailed history, audiometry referral, and targeted MRI or vascular imaging when the pattern suggests a neurological cause.

Cervical sensations can coexist, but dizziness is often multifactorial and needs systematic assessment rather than assuming a single neck cause.
Yes; vertigo is the sensation of spinning. Dizziness is a broader term including lightheadedness, unsteadiness, and near-fainting. Different causes underlie each.
Vertigo is a subtype of dizziness; other forms include lightheadedness and imbalance, each suggesting different causes.
BPPV (Benign Paroxysmal Positional Vertigo) causes brief spinning with head movement. Positional maneuvers performed by a healthcare provider are often effective.
