Horizontal-canal paroxysmal positional vertigo (HC-PPV) is a vestibular syndrome due to canalolithiasis of the horizontal canal. The more common posterior-canal paroxysmal positional vertigo has a well defined and effective therapy, while there have been few reports on physical therapy for HC-PPV, and these have been tried in relatively few patients. We report the results of two different types of treatment of HC-PPV in 92 patients. A group of 21 untreated patients acted as a control group. One method, known as forced prolonged position (FPP), proposes liberating the affected canal by gravitation, and involves having the patient lie on the healthy side for many hours. The other method (the barbecue rotation) is a liberatory manoeuvre which proposes to expel the otoconia from the canal by rotating the patient 270 degrees around the longitudinal axis of the body in rapid steps of 90 degrees. FPP was successful in more than 70% of our patients; the barbecue rotation had slightly less successful but more immediate results. Both methods enable otoconial debris to migrate into the posterior canal. We suggest treating all patients with the two methods in succession.
水平半规管阵发性位置性眩晕（HC-PPV）是一种由于水平半规管管结石症引起的前庭综合征。较为常见的后半规管阵发性位置性眩晕有明确有效的治疗方法，而关于HC-PPV物理治疗的报道较少，且尝试治疗的患者相对较少。我们报告了92例HC-PPV患者两种不同治疗方法的结果。一组21例未经治疗的患者作为对照组。一种方法称为强迫长时间体位（FPP），建议通过重力作用使患侧半规管解脱，让患者向健侧卧位数小时。另一种方法（烧烤旋转法）是一种解脱手法，建议通过让患者围绕身体纵轴以90度的快速步骤旋转270度，将耳石从半规管中排出。FPP在我们超过70%的患者中取得成功；烧烤旋转法的成功率略低，但效果更立竿见影。两种方法都能使耳石碎片向后半规管迁移。我们建议对所有患者依次采用这两种方法进行治疗。
