목적: Dizziness and imbalance are one of the most common complaints in all people and benign paroxysmal positional vertigo (BPPV) in the most frequent peripheral vertigo. It is a well-characterized entity and generally easy to treat. To compare the clinical characteristics of benign paroxysmal positional vertigo (BPPV) according to each generation 방법:We retrospectively reviewed the clinical records of 1429 patients who were diagnosed as BPPV at the Dizziness Clinic in Konyang University Hospital, Korea between 2009 and 2014. We divided patients into five groups group A (under 20 years), group B (21- 40 years), group C (41-60years), group D (61-80 years), E group (over 80 years). We treated patients with frequently-repeated CRPs such as the modified Epley maneuver or a barbecue rotation every 2 or 3 days in the outpatient clinic. 결과:Among 1429 patients with BPPVs, 30 (2.1%) were group A, 194 (13.6%) group B, 695 (48.6%) group C, 442 (30.9%) group D, and 68 (4.8%) group E. Although the most common cause was idiopathic in all groups, trauma were secondly common in group A,B,C, and D, AVN in group E. Group E developed most commonly in the posterior semicircular canals, while A, B, C and D developed most commonly in the lateral semicircular canals. The average frequencies of canalith repositioning procedures (CRPs) were 1.2, 1.5, 1.6, 1.6, 1.8 times in each group (P>0.05). The efficiency of CRP also did not the significant difference in each group (P>0.05). Recurrence rates were 10.0%, 16.5%, 16.5%, 15.4% and 20.6% in each group, respectively (P<0.05). 결론:Though patients with BPPV showed higher recurrence rates as they ages, the efficiency of CRP did not show the significant difference in all groups. Therefore, an appropriate with CRPs and prolonged follow-up are required in order to detect recurrences.
