AbstractObjective:The aim of this study is to retrospective analysis the clinic features of 118 cases of benign paroxysmal positional vertigo after trauma. Method:Analyzes clinic features of injury in 118 cases of benign paroxysmal positional vertigo after trauma, and classified and localized the craniocerebral trauma. The 118 cases were tested with different positioning tests in the sequence of Dix hallpike test and rolling test. Then, proper otolith manual reduction was given. Result:In 118 cases of BPPV after trauma including 35 cases of skull fracture, 6 cases of concussion, 17 cases of scalp hematoma, 28 cases of scalp laceration, 14 cases of mild brain contusion and 18 cases of head combined injury. The distributions of head injury were 57 at front temporal, 24 at top, 22 at occipital and 15 at maxillofacial region. The latency of BPPV after head injury varies from 1day to 1month. The incidence of 3-7 day after head injury was the highest, followed by 7-14 days, 0-3 days, and the lowest incidence rate of 14 day to 1 month. Canal type 118 BPPV patients after head injury accounting for up to 57.6% of the horizontal semicircular canal accounted for 33.1%, mixed 9.3%. Conclusion:The patients with front temporal trauma and skull fracture were prone to have BPPV. The peak incidence of BPPV was 3-14 days after head injury. The most common type of BPPV was PC BPPV, and the HC BPPV was the second type. A good curative effect can be manipulative reduction after trauma BPPV..Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.
