目的探讨单侧后半规管（PSCC）封堵术治疗难治性双侧PSCC型良性阵发性位置性眩晕（P-BPPV）的疗效。其中，3例患者患有双侧P-BPPV，其中2例患者保守治疗无效超过1年。我们计划对这2例患者进行分期PSC封堵手术;最初治疗一侧，对侧治疗6个月后，第一次手术后，两例患者的眩晕和眼球震颤症状改善，手术侧和非手术侧无变化。非手术侧行Epley手法。1例非手术侧治愈。在另一例病例中，尽管P-BPPV未完全消退，但患者对单侧手术的结果感到满意，因为他现在能够在床上向手术侧翻身，没有眩晕。手术前，他在床上稍微翻身时就会出现眩晕。结论我们认为，即使是单侧PSCC封堵手术对某些患有顽固性双侧P-BPPV的患者也有效。
ObjectiveTo investigate the effectiveness of unilateral posterior semicircular canal (PSCC)-plugging surgery for patients with intractable bilateral PSCC-type benign paroxysmal positional vertigo (P-BPPV).MethodsFrom July 2011 to December 2015, we diagnosed 136 patients with P-BPPV. Of these, 3 patients had bilateral P-BPPV, and in 2 of the 3, the condition had been refractory to conservative treatment for more than 1 year. We planned a staged PSCC-plugging surgery for these 2 patients; initially one side was treated, and the contralateral side was treated 6 months later.ResultsAfter the first surgery, both patients experienced improvement in symptoms of vertigo and nystagmus on the operated side and no change on the non-operated side. Patients underwent the Epley maneuver for the non-operated side. In one case, the non-operated side was cured. In the other case, although the P-BPPV was not completely resolved, the patient was satisfied with the result of unilateral surgery because he was now able to turn in bed to the operated side without vertigo. Before surgery, he had experienced vertigo when turning even slightly in bed.ConclusionWe propose that even unilateral PSCC-plugging surgery is effective for some patients with intractable bilateral P-BPPV.
