Abstract
OBJECTIVES: We studied the clinical characteristics, nystagmographic findings, and treatment outcome of a group of patients with benign paroxysmal positional vertigo (BPPV) secondary to mild head trauma and compared them with a group of patients with idiopathic BPPV.
METHODS: The medical records of 33 patients with BPPV associated with mild head trauma were reviewed. Data of a complete otolaryngological, audiological, neurotologic, and imaging evaluation were available for all patients. Three hundred and twenty patients with idiopathic BPPV were used as a control group.
RESULTS: The patients with BPPV secondary to mild head trauma presented the following features, in which they differed from the patients with idiopathic BPPV: (1) lower mean age, with more intense symptoms; (2) increased rate of horizontal and anterior semicircular canal involvement and frequent multiple canal and bilateral involvement; (3) greater incidence of canal paresis and presence of spontaneous nystagmus; (4) poorer treatment results, attributed mainly to coexisting canal paresis in many patients, and higher rate of recurrence.
CONCLUSIONS: Benign paroxysmal positional vertigo associated with mild head trauma differs from idiopathic BPPV in terms of several epidemiological and clinical features; it responds less effectively to treatment and is prone to recurrence.
