继发于突发性聋的良性阵发性位置性眩晕的临床特点

Clinical characteristics of benign paroxysmal positional vertigo secondary to sudden deafness

目的:回顾性分析继发于突发性聋的良性阵发性位置性眩晕(BPPV)患者的临床表现和治疗结果,并探讨其可能的发病机制。方法:观察178例突发性聋患者中继发BPPV的发病情况和治疗效果,所有患者均按照中华医学会耳鼻咽喉科学分会制订的诊治标准。结果:①突发性聋患者中有31例继发BPPV,后半规管BPPV26例,水平半规管BPPV 5例;均发生于突发性聋同侧的患耳,左耳16例,右耳15例。②突发性聋至继发BPPV的间隔在1周内27例,1周～1个月3例,1～3个月1例。③所有继发于突发性聋的BPPV均经手法复位治愈。结论:BPPV可继发于突发性聋,其中以后半规管BPPV常见,耳石复位是有效的治疗方法。

Objective： To retrospectively analyze the clinical characteristics of the benign paroxysmal positional vertigo（BPPV） secondary to the sudden deafness （SD） and to explore pathogenetic mechanism. Method：One hun- dred and seventy-eight cases of the SD in our department were retrospectively analyzed. They were all treated un- der the guidance of clinical guidelines. Resuit：① In all these patient s with SD, there were 31eases with BPPV sec- ondary to the SD. There were 26 cases of BPPV of posterior semicircular canal and 5 cases of BPPV of lateral BP- PV semicircular canal. All patients with BPPV were diagnosed as the same ears as the SD, including 16 cases on left sides and 15 on right sides. ②The interval between the onset of SD and BPPV was less than one week in 27 cases, between one week and one month in 3 eases, and between one and three months in 1 case. ③All patients with BPPV secondary to the SD were cured with Epley maneuver or Barbecue roll maneuver. Conclusion：The oc- currence of BPPV may follow SD,and the major of BPPV secondary to the SD occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy to the secondary BPPV.
