**Question:** Latest treatment for BPPV is:

A. Vestibular rehabilitation therapy (VRT)
B. Calcium channel blockers
C. Audiometry
D. Endoscopic sinus surgery

**Core Concept:** Benign Paroxysmal Positional Vertigo (BPPV) is a type of vertigo characterized by episodes of dizziness and labyrinthine dysfunction. The most common cause is degeneration of otoconia (mineral crystals) in the semicircular canals of the inner ear. Vestibular rehabilitation therapy (VRT) is a non-invasive treatment method that focuses on retraining the brain to compensate for the disturbed balance signals.

**Why the Correct Answer is Right:** Vestibular rehabilitation therapy (VRT) is the most recent treatment approach for BPPV. VRT is based on the principle of retraining the brain to adapt to the altered balance signals and improve the patient's balance and vertigo control. In VRT, patients are educated about their condition, and exercises are performed to stimulate the affected vestibular system. These exercises help in re-establishing the connection between the brain and vestibular system, improving balance and vertigo control.

**Why Each Wrong Option is Incorrect:**

B. Calcium channel blockers are medications primarily used to treat hypertension and arrhythmias. They do not directly address the issue of vestibular dysfunction in BPPV.

C. Audiometry is a test used to evaluate hearing function, not specifically for treating vertigo or balance disorders like BPPV.

D. Endoscopic sinus surgery is a procedure performed for conditions like nasal polyps and sinusitis. It is unrelated to treating vertigo caused by BPPV.

**Clinical Pearl:** BPPV should be diagnosed and treated by a healthcare professional experienced in vestibular rehabilitation therapy (VRT). In cases where VRT is ineffective or not suitable, referral to an otolaryngologist or an experienced vestibular specialist may be necessary for further management options, such as canalith repositioning procedure (CRP) or manoeuvres like Epley, Semont, and Dix-Hallpike.
