Benign paroxysmal positional vertigo (BPPV) is most often a self-limited disorder arising from the posterior semicircular canal of the undermost ear in the Hallpike position. Some individuals with this disorder have severe and protracted symptoms requiring more than expectant therapy. We describe two patients with intractable BPPV and profound sensorineural hearing loss in the affected ear treated by transmastoid posterior semicircular canal occlusion. Postoperatively, both were relieved of their BPPV and demonstrated preserved lateral semicircular canal function as measured by electronystagmography. We feel this new procedure provides a simpler and possibly safer alternative to singular neurectomy and should be given future consideration in the treatment of intractable BPPV in a normal-hearing ear.
良性阵发性位置性眩晕（BPPV）通常是一种自限性疾病，由Hallpike位时最下方耳朵的后半规管引起。一些患有这种疾病的个体有严重且持续的症状，需要的治疗超出了观察等待治疗的范畴。我们描述了两名患有顽固性BPPV且患侧耳朵有严重感音神经性听力损失的患者，他们接受了经乳突后半规管阻塞术治疗。术后，两人的BPPV均得到缓解，并且通过眼震电图测量显示外侧半规管功能得以保留。我们认为这种新手术为单神经切除术提供了一种更简单且可能更安全的替代方法，在治疗听力正常耳朵的顽固性BPPV时应在未来予以考虑。
