What is Tinnitus?
Tinnitus is the perception of sound in the ears or head without an external source. It may present as ringing, buzzing, whistling, or other sounds, and can be constant or intermittent.
Types of Tinnitus
Subjective Tinnitus: Heard only by the affected individual. Accounts for 99% of cases. Results from inner ear or neural pathway issues.
Objective Tinnitus: Rarely, healthcare providers can hear the sound using instruments. Usually related to blood vessel pulsation or muscle contractions near the ear.
Common Underlying Causes
Age-Related Hearing Loss: Presbycusis is the most common cause, especially in older adults.
Noise Exposure: Loud concerts, machinery, or gunshots can damage inner ear hair cells.
Ear Wax Impaction: Accumulated cerumen can create phantom sounds. Removal often resolves tinnitus.
Ear Infections: Middle ear infections commonly cause temporary tinnitus.
Head and Neck Trauma: Concussions and whiplash injuries can trigger tinnitus onset.
Medication Side Effects: Certain medications (aminoglycosides, aspirin, diuretics) list tinnitus as a side effect.
Vascular Issues: High blood pressure and atherosclerosis can create blood flow-related sounds.
Tinnitus Triggers
For many, specific factors worsen tinnitus:
- Caffeine consumption
- Sodium-rich foods
- Alcohol
- Stress and anxiety
- Certain medications
- Loud noise exposure
Professional Evaluation
A comprehensive evaluation by an audiologist or otolaryngologist identifies the underlying cause and guides appropriate management. Imaging may be necessary for some cases.
Understanding your tinnitus type and triggers is essential for developing an effective management strategy.
