Benign paroxysmal positional vertigo in patients after mild traumatic brain injury.

BACKGROUND: Post-traumatic vertigo, dizziness and balance disorders following head trauma range from 15% to 78% in the general population. Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder in such patients.

OBJECTIVES: The aim of the study was to assess the occurrence of BPPV in patients with mild traumatic brain injury (MTBI) and determine the outcome of treatment.

MATERIAL AND METHODS: A group of 179 patients, with a mean age of 45.2 years, complaining of vertigo/ /dizziness and balance instability after MTBI, was enrolled into the study. All these patients were diagnosed and treated in the Department of Otolaryngology (Medical University of Lodz, Poland) between the years 2012 and 2014. Anamnesis and otoneurological examination were conducted in each patient. The diagnosis was based on the medical history, the Dix-Hallpike test or the rollover test. The treatment comprised the Epley, barbecue and particle repositioning (RM) maneuvers.

RESULTS: Nineteen patients (10.6%) complained about attacks of vertigo elicited by positional changes. The diagnosis of BPPV was confirmed in 9 (47.4%) patients: 8 cases with a positive Dix-Hallpike test and 1 with the roll test. In 10 cases, a high probability of BPPV was diagnosed based on the medical history. Eight patients were treated by a single Epley maneuver and 1 patient by the barbecue roll. In 4 (44.4%) patients, the maneuvers were repeated. On the follow-up examination, the patients were not found to have vertigo.

CONCLUSIONS: Benign paroxysmal positional vertigo should be diagnosed and treated successfully in patients after head trauma.
