水平半规管良性阵发性位置性眩晕手法复位疗效分析

目的探讨手法复位治疗水平半规管良性位置性眩晕的疗效。方法对87例患者采用不同的手法复位：水平向地性眼震患者均接受Barbecue耳石复位治疗；背地性眼震患者采用Gufoni法、改良Semont解脱法及12小时强迫侧卧位法治疗；观察疗效。结果70例水平向地性眼震患者采用Barbecue法复位1次治愈率88．6％。17例背地性眼震患者采用Gufoni法转换眼震方向，治愈5例，改良Semont解脱法治愈8例，强迫侧卧位法治愈1例，最终仍有3例背地性眼震患者未能治愈。结论对于水平半规管位置性眩晕，采用Barbecue手法复位双侧向地性眼震类型效果良好，而双侧背地性眼震手法复位相对困难，尚待进一步研究。

The efficacy of repositioning maneuver for horizontal semicircular canal benign paroxysmal positional vertigo

Objective To investigate the efficacy of repositioning maneuver for horizontal semicircular canal benign paroxysmal positional vertigo （HC-BPPV）. Methods Barbecue maneuver was applied in 70 pa- tients with bilateral geotropic nystagmus; Gufoni maneuver, modified Semont maneuver, and forced prolonged position were used in 17 patients with bilateral apogeotropic nystagmus. The efficacies were observed. Results The one-time recovery rate of Barbecue maneuver was 88.6%. 5 patients with apogeotropic nystagmus were cured by switching to geotropic type after Gufoni maneuver. Eight patients with apogeotropic nystagmus who never switched to geotropic type became symptom-free after being treated with modified Semont maneuver, one patient who did not response to previous maneuver were cured after use of forced prolonged position, and 3 pa- tients with apogeotropic nystagmus did not response to the therapy. Conclusions Barbecue maneuver is effec- tive in the treatment of HC-BPPV with bilateral geotropic nystagmus; but it is difficult to treat bilateral apo- geotropic nystagmus with this maneuver. The maneuver remains to be further studied.
