Abstract

OBJECTIVE: To determine the rate of symptom resolution in patients with posttraumatic benign paroxysmal positional vertigo (BPPV) and to determine if it differs from resolution rates in patients with BPPV and without a history of head trauma. DATA SOURCES: Systematic review of the literature was performed using Medline, EMBASE, and Cochrane databases. English and French articles meeting inclusion criteria and published between 1946 and October 2014 were included. REVIEW METHODS: Data were independently extracted from the articles by 2 reviewers using data collection forms developed a priori. Inclusion and exclusion criteria were decided a priori. Studies were included if they reported on at least 1 case of posttraumatic BPPV (t-BPPV), reported on outcomes of all patients with t-BPPV, had a clearly defined inception point, and provided a clear diagnosis of BPPV (defined a priori by reviewers).

RESULTS: A total of 3017 titles, 362 abstracts, and 67 articles were reviewed, from which 16 articles met inclusion criteria and underwent data extraction. There were a total of 207 patients with posttraumatic BPPV identified. Among the 207 patients, 151 (73%) had resolution of symptoms. The T-BPPV patients may have more multi-canal involvement and may require more repositioning maneuvers for resolution compared to patients with nontraumatic BPPV.

CONCLUSIONS: Available evidence does not support the notion that symptom resolution rates in patients with posttraumatic BPPV are worse than those with nontraumatic BPPV. However, well-designed studies with adequate cohorts are lacking. Additional well-executed studies are needed to confirm this lack of difference in resolution rates.
