Objective To compare characteristics between traumatic and idiopathic benign paroxysmal positional vertigo (BPPV) focusing on outcomes. Study Design Retrospective chart review. Setting High‐volume tertiary otology center. Subjects and Methods Records of patients with BPPV treated at a single institution from 2007 to 2017 were analyzed. Traumatic BPPV was defined as BPPV symptoms beginning within 30 days following head trauma. Patient, disease, treatment, and outcome characteristics were compared between traumatic and idiopathic BPPV groups. Results A total of 1378 patients with BPPV were identified, 110 (8%) of which had traumatic BPPV. The overall resolution rate was 76%, and the recurrence rate was 38%. Patients with traumatic BPPV were younger (mean age: 61 vs 65 years, P =. 007) and more likely to be male (40% vs 27%, P =. 004) than patients with idiopathic BPPV. Traumatic BPPV was more likely to affect both ears (32% vs 19%, P =. 009). No significant association was detected between trauma history and resolution rate, recurrence rate, number of treatment visits, or affected semicircular canals. Conclusion Patients with traumatic BPPV are more likely to be young and male than those with idiopathic disease. Although traumatic BPPV is often bilateral, outcomes for traumatic BPPV may be similar to those for idiopathic BPPV, contrary to prior reports.
