Efficacy of computer-controlled repositioning procedure for benign paroxysmal positional vertigo

Area of Science:

• Neurology
• Otolaryngology
• Vestibular System Disorders

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder.
• Posterior canal BPPV is the most frequent subtype.
• Current treatments include canalith repositioning procedures (CRP).

Purpose of the Study:

• To evaluate the short-term efficacy and safety of computer-controlled CRP.
• To compare computer-controlled CRP with the standard Epley maneuver for posterior canal BPPV.

Main Methods:

• A prospective case series involving 132 patients with idiopathic posterior canal BPPV.
• Treatment administered via computer-controlled CRP, mimicking the Epley maneuver.
• Efficacy assessed by resolution of vertigo and nystagmus on Dix-Hallpike test at 1-week follow-up.

Main Results:

• Complete resolution of vertigo and nystagmus was achieved in 81.8% of patients after 1 week.
• The success rate (81.8%) was comparable to the established ~80% success rate of standard CRP.
• No significant adverse effects were noted, with only two patients experiencing conversion to lateral canal BPPV.

Conclusions:

• Computer-controlled CRP is an effective and safe treatment for posterior canal BPPV.
• The success rate is similar to the traditional Epley maneuver.
• The procedure is easy to perform, offering a viable alternative treatment option.
