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效果分析

The efficacy of Gufoni maneuver for treating geotropic nystagmus horizontal semicircular canal benign paroxysmal positional vertigo

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。

Objective To investigate the efficacy of Gufoni maneuver for treating geotropicnystagmus horizontal semicircular canal benign paroxysmal positional vertigo(BPPV). Methods Weretrospectively analyzed 87 patients diagnosed as geotropic nystagmus horizontal semicircular canal BPPVfrom January to December 2016. All patients were treated by Gufoni maneuver twice and examined on thenext day to access the status of BPPV. Patients still with geotropic nystagmus or dizziness were treated byGufoni maneuver twice again and examined after 30 min. The effect was assessed by "Diagnosis basis andcurative effect appraisal of benign paroxysmal positional vertigo(2006, Guiyang)". Results The successrate 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 byforced prolonged position(FPP) and recovered after one week, and 4 of whom turned to be posteriorsemicircular canal BPPV and were treated by Epley maneuver successfully. Conclusions Gufonimaneuver is proved to be a good treatment for geotropic nystagmus horizontal semicircular canal BPPV andthe efficacy increases after repeated treatment.
