Efficacy of computer-controlled repositioning maneuvers for post-traumatic benign paroxysmal positional vertigo.

BACKGROUND

Post-traumatic benign paroxysmal positional vertigo (T-BPPV) is considered to be one of the most common secondary BPPV. But the exact diagnosis and treatment strategy of t-BPPV remains challenging to physicians because of patients physical limitations. In this situation, we used computer-controlled repositioning maneuvers (CCRM) to make t-BPPV patients diagnosis and treatment easier.

OBJECTIVES

This study aims to evaluate the short-term effect of CCRM for treating t-BPPV patients.

MATERIAL AND METHODS

A total of 36 patients diagnosed with t-BPPV were treated by CCRM. CCRM was carried out every 48 h until patients were cured and patients were follow-up after treatment for six-month. The results of Dix-Hallpike test and supine roll test were the main outcome measures to assess efficacy of the treatment.

RESULTS

Overall, 24(66.7%) patients had involvement of multiple semicircular canals. All patients obtained final resolution of vertigo and nystagmus with a maximum of 18 maneuvers. No significant adverse effect and complication occurred during the treatment process.

CONCLUSIONS

T-BPPV is apt to involve multiple canals, and is difficult to treat, with no gender tendency. CCRM is effective and secure for the treatment of t-BPPV, especially for patients with cervical movement limitation.

SIGNIFICANCE

With the help of CCRM, we are able to make t-BPPV patients diagnosis and treatment more accurate and simple.
