An evaluation was made on ten patients with benign paroxysmal positional vertigo (BPPV) in whom transection of the posterior ampullary nerve was performed by the middle ear approach under local anesthesia. The undermost ear in the provocative test position was selected for surgery. All ten patients were relieved of positional vertigo by the procedure. Of the five patients who were relieved of BPPV by posterior ampullary nerve transection prior to 1974, the long-term follow-up on four revealed continued relief of vertigo. Five additional patients treated by this surgical procedure since 1975 have also experienced relief from BPPV, but a moderate sensorineural hearing loss occurred in one patient. Two additional patients with BPPV were explored surgically but the singular canal could not be located. Persistence of the vertigo in these two patients strengthens the conclusion that the posterior semicircular canal sense organ is largely responsible for BPPV.
对10例良性阵发性位置性眩晕（BPPV）患者进行了评估，这些患者在局部麻醉下通过中耳入路进行了后半规管壶腹神经切断术。在激发试验位置中最低的耳朵被选作手术对象。所有10例患者通过该手术缓解了位置性眩晕。在1974年之前通过后半规管壶腹神经切断术缓解BPPV的5例患者中，对4例的长期随访显示眩晕持续缓解。自1975年以来，另外5例接受该手术治疗的患者也从BPPV中得到缓解，但1例患者出现了中度感音神经性听力损失。另外2例BPPV患者接受了手术探查，但未找到单管。这2例患者眩晕持续存在，强化了后半规管感觉器官在很大程度上导致BPPV的结论。
