BACKGROUND AND OBJECTIVES:Benign paroxysmal positional vertigo (BPPV) has a lot of causes. Except idiopathic BPPV, the most common cause of BPPV was trauma. The aim of this study was to study its character, diagnosis, prognosis and treatment. MATERIALS AND METHOD:We retrospectively collected the 14 patients by reviewing charts, analyzing vestibular function tests. RESULTS:Post traumatic BPPV had characters different from idiopathic BPPV in patient' sex ratio and age distribution. The mean age of patients was 40 years old, men were 11 women were 3. In the mechanisms of trauma, traffic accidents were 11, assault was 1, and fall down were 2. In types, posterior semicircular canal were 10, horizontal semicircular canal were 4. In origins, cupulolithiasis were 8, canalolithiasis were 6. Treatment and prognosis were similar to those of idiopathic BPPV. CONCLUSION:But origin, diagnostic criteria, treatment and prognosis are identical with idiopathic BPPV. Therefore, in evaluating post traumatic BPPV patients, we need correct diagnosis and treatment together by history taking, physical examination and vestibular function tests. And by this, we can treat idiopathic BPPV accurately, reduce expense and time for patients to return daily life.
