Study Notes

Definition of Tinnitus

Tinnitus involves perceiving sounds like whistling, hissing, buzzing, or ringing without any external source.
Can occur unilaterally or bilaterally; may be acute or chronic and intermittent or constant.
Approximately 10–15% prevalence in the US adult population, increasing with age, more common in men and smokers.

Types of Tinnitus

Objective Tinnitus: Rare condition detected by a doctor; can be caused by turbulent blood flow or vascular tumors.
Subjective Tinnitus: Common sensation of sound without an external source, often related to ear conditions like hearing loss or infections.

Causes of Subjective Tinnitus

Otological Causes: Impacted wax, fluid in the middle ear, otitis media, Meniere’s disease, noise-induced hearing loss, and acoustic neuroma.
Neurological Causes: Head injuries, multiple sclerosis, and post-meningitis complications.
Metabolic Causes: Hypothyroidism, hyperthyroidism, obesity, and vitamin B12 deficiency.
Cardiovascular Causes: Hypertension, cardiac arrhythmias.
Psychogenic Causes: Anxiety and depression.

Causes of Objective Tinnitus

Vascular Conditions: AV shunts, arterial bruit from carotid stenosis or aneurysm.
Structural Causes: Patulous eustachian tube, palatal myoclonus, myoclonus of the tensor tympani.

Pathophysiology

Damage to cochlea or auditory nerve leads to reduced input to auditory neurons; results in abnormal neural activity in the auditory cortex.
Brain feedback loops that regulate auditory signals become impaired, leading to unusual auditory perceptions.
Key risk factors for tinnitus include long-term loud noise exposure, head/neck injuries, and infections.

Diagnosis of Tinnitus

Medical History: Characterize tinnitus type (unilateral/bilateral) and assess risk factors.
Physical Examination: Use otoscope for ear abnormalities, perform head and neck auscultation for bruits, and conduct a neurologic examination.
Audiological Tests: Include pure tone audiometry and tympanometry.
Additional Tests: Imaging (CT/MRI) for specific symptoms; blood tests for treatable causes; autoimmune and infectious workups if needed.

Treatment and Management

Identify and treat underlying causes if possible; management focuses on symptom control.
Reassurance & Psychotherapy: Adaptation strategies for living with tinnitus.
Relaxation Techniques & Biofeedback: Stress-reduction methods.
Sedatives: May be used initially for adjustment.
Tinnitus Masking: Using sound devices to mask tinnitus, especially at bedtime; hearing aids can provide additional benefit.

Pharmacological Treatments

Clonazepam: A benzodiazepine reducing neuronal hyperactivity.
Carbamazepine: Anticonvulsant for abnormal auditory nerve firing.
Nimodipine: Calcium channel blocker potentially benefiting vascular-related tinnitus.

Alternative and Innovative Therapies

Acupuncture: Promotes circulation and stress relief.
Ginkgo Biloba Extract: Believed to enhance blood circulation to the brain; evidence is mixed.
Intratympanic Steroids: Injection for inner ear inflammation or sudden hearing loss.
Tinnitus Retraining Therapy (TRT): Includes counseling and sound therapy, lasting 18–24 months with significant improvement in many patients.

Summary

Tinnitus is a prevalent auditory condition with various causes and types.
Diagnosis requires thorough history-taking and clinical evaluation.
Management focuses on addressing underlying causes where possible and symptom relief through multiple strategies including therapies and sound masking.
