Can Type of Dizziness Influence the Vestibular Caloric Test Result?

Area of Science:

• Otolaryngology
• Neurology
• Audiology

Background:

• Vestibular tests are crucial for diagnosing labyrinth diseases and assessing vestibular system function.
• The caloric test is the gold standard for objective, unilateral vestibular function measurement.

Purpose of the Study:

• To correlate different types of dizziness with caloric test results.
• To analyze the relationship between dizziness symptoms and objective vestibular findings.

Main Methods:

• A descriptive study analyzed records of 892 patients with balance disorders from 2000-2020.
• Evaluated variables included sex, age, hearing loss, tinnitus, and caloric test results.

Main Results:

• Normal caloric test results were found in 57.4% of patients.
• Peripheral vestibular disease was identified in 40.1%, and central disease in 2.5%.
• Vertigo with tinnitus/hearing loss correlated with peripheral abnormalities; instability linked to bilateral vestibular weakness or central disorders.

Conclusions:

• Vertigo associated with tinnitus and/or hearing loss warrants clinical observation for unilateral peripheral lesions.
• Instability suggests central disease or bilateral peripheral lesions, guiding further diagnostic evaluation.
