540° versus 360° barbecue rotation for HSC-canalithiasis

Area of Science:

• Neurology
• Otolaryngology
• Vestibular Disorders

Background:

• Horizontal semicircular canal canalithiasis is a common cause of vertigo.
• Existing treatment variations include barbecue rotation, but a 540° approach has not been previously reported.

Purpose of the Study:

• To compare the efficacy of a modified 540° barbecue rotation technique against the traditional 360° method for treating horizontal semicircular canal canalithiasis.

Main Methods:

• Sixty patients diagnosed with horizontal semicircular canal canalithiasis were prospectively assigned to either a 540° (Br540) or 360° (Br360) barbecue rotation group.
• Treatment involved log roll maneuvers, with weekly repetitions allowed until symptom resolution (vertigo and nystagmus).

Main Results:

• The 540° group demonstrated a significantly higher success rate with a single treatment application (approximately 90% vs. 61%).
• Fewer canalith repositioning procedures (CRPs) were required in the 540° group compared to the 360° group, even when including complex cases (p=0.011) and excluding them (p=0.027).

Conclusions:

• The modified 540° barbecue rotation technique appears to be more effective than the 360° method for treating horizontal semicircular canal canalithiasis.
• This approach may offer a more efficient treatment option for patients suffering from this vestibular disorder.
