摘要：

目的 探讨 Gufoni法治疗向地性眼震型水平半规管良性阵发性位置性眩晕的有效性。方法 选择 2016 年 1-12 月共 87 例向地性眼震型水平半规管良性阵发性位置性眩晕患者，均采用 Gufoni法复位 2 次，次日复查，仍存在向地性眼震和眩晕者，再次行 Gufoni 法复位 2 次，30 min 后复查。结果 87 例患者经 Gufoni 法复位后，次日复查有效率为 71.26%（62/87），再次复位后有效率为 86.21%（75/87）。12 例无效患者中 8 例仍存在向地性眼震，予强迫健侧卧位法治愈；4 例转变为后半规管良性阵发性位置性眩晕，予 Epley 法复位治愈。结论 Gufoni法可以作为治疗向地性眼震型水平半规管良性阵发性位置性眩晕的有效方法，且多次重复可以提高疗效。

Abstract:

Objective To investigate the efficacy of Gufoni maneuver for treating geotropic nystagmus horizontal semicircular canal benign paroxysmal positional vertigo (BPPV). Methods We retrospectively analyzed 87 patients diagnosed as geotropic nystagmus horizontal semicircular canal BPPV from January to December 2016. All patients were treated by Gufoni maneuver twice and examined on the next day to access the status of BPPV. Patients still with geotropic nystagmus or dizziness were treated by Gufoni maneuver twice again and examined after 30 min. The effect was assessed by "Diagnosis basis and curative effect appraisal of benign paroxysmal positional vertigo (2006, Guiyang)". Results The success rate of first treatment by Gufoni maneuver achieved to 71.26% (62/87) and increased to 86.21% (75/87) after the second treatment. Among these patients, 12 patients failed to recover, 8 of whom were treated by forced prolonged position (FPP) and recovered after one week, and 4 of whom turned to be posterior semicircular canal BPPV and were treated by Epley maneuver successfully. Conclusions Gufoni maneuver is proved to be a good treatment for geotropic nystagmus horizontal semicircular canal BPPV and the efficacy increases after repeated treatment.
