Outcome of canalith repositioning manoeuvre in benign paroxysmal positional vertigo in children and adolescents: A systematic review.

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is a debilitating condition that has been significantly described in adults. Recent data points out that BPPV occurs in children as well. Canalith repositioning manoeuvre (CRM) has shown promising results amongst adult patients with BPPV.

OBJECTIVE: We reviewed the literature to determine the outcome of CRM in children and adolescents with BPPV.

METHODS: A literature search was conducted over 1 month (March 2022). The primary outcome was defined as the resolution of positional nystagmus and symptoms, and secondary outcomes were determined by the presence of recurrence and the number of attempts of CRM.

RESULTS: Ten articles were selected based on our objective and selection criteria. A total of 242 patients were included, with a mean of 10.9 years. BPPV was diagnosed based on history and positional nystagmus in all patients (100%). CRM was performed in 97.9% of patients, whereby 80.5% recovered following a single attempt of CRM. Recurrence of symptoms was identified in 10% of patients with no reported major complications.

CONCLUSION: CRM has demonstrated promising results in children and adolescents. The quality of evidence is limited until a better-quality study involving randomised controlled studies with a larger sample size is completed.
