Early management for traumatic benign paroxysmal positional vertigo in traumatically injured patients

Objectives The purpose of this study was to identify the clinical features of posttraumatic benign paroxysmal positional vertigo (t-BPPV) in traumatically injured patients, investigating the effectiveness of the early diagnosis and management including canalith repositioning procedures (CRPs). Patients and methods The subjects of the present study were 74 patients who were hospitalized in the Trauma Center, Ajou University Hospital. We investigated the relationship between injury mechanisms and t-BPPV. Patients with t-BPPV were categorized into mild (typical BPPV) and severe (bilateral, recurrent, or persistent) types. Results Of the 74 patients, 41 were diagnosed with t-BPPV. Nineteen were mild and 22 were severe types. ‘A fall’ (36%) and ‘pedestrian car accident’ (32%) were common as the injury mechanisms provoking severe t-BPPV. In the severe t-BPPV group, they were hospitalized longer (as median value, 20 days in the severe group vs. 10 days in the mild group, P = 0.004), stayed longer in intensive care unit (3 days vs. 0 days, P = 0.016), and needed more days until the BPPV management (13.5 days vs. 6 days, P = 0.021). Major trauma (the Injury Severity Score >15) patients had a longer time to implementation of the first CRPs (10 days in major trauma and 3 days in minor trauma patients, P = 0.019). Conclusions Severity of trauma and longer duration of ICU treatment were factors delaying BPPV management. This delay could negatively affect the progress of t-BPPV. Diagnostic and therapeutic maneuvers including CRPs should be performed as early as possible, even in severely injured patients.
