A series of 15 patients with intractable benign paroxysmal positional vertigo (BPPV) who had fenestration and occlusion of the posterior semicircular canal (FOP) surgery commencing in December 1990 are reported. Follow-up was from 14 to 40 months. All patients reported a cure of their positional vertigo. No patient regretted having the surgery. All patients had a negative Dix-Hallpike test post-operatively and the test remained negative for the duration of follow-up. Eight patients had a mild high frequency sensorineural hearing (SNHL) loss post-operatively which had almost recovered six months later. No patient reported any change in their hearing following surgery. Of the 10 patients who did not have pre-operative tinnitus, six developed tinnitus but it was not considered significant by them. All patients developed mild unsteadiness following surgery which gradually improved with mobilization and physiotherapy if necessary. The operation preserves hearing, is technically straightforward, well-tolerated and effective.
报告了自1990年12月起开始接受后半规管开窗闭塞术（FOP）手术的15例难治性良性阵发性位置性眩晕（BPPV）患者。随访时间为14至40个月。所有患者均报告其位置性眩晕已治愈。没有患者后悔接受手术。所有患者术后Dix-Hallpike试验均为阴性，且在随访期间该试验一直保持阴性。8例患者术后出现轻度高频感音神经性听力损失（SNHL），但6个月后几乎恢复。没有患者报告术后听力有任何变化。在10例术前无耳鸣的患者中，6例出现耳鸣，但他们认为不严重。所有患者术后均出现轻度不稳，必要时通过活动和物理治疗逐渐改善。该手术保留听力，技术操作简单，耐受性良好且有效。
