During the past 18 years, 102 singular neurectomies (SN) were performed on 95 patients with chronic cupulolithiasis of the posterior canal sense organ. Bilateral sequential singular neurectomies were performed in 7 patients and unilateral singular neurectomies in 88 patients. Ninety-nine (97%) of the 102 singular neurectomies completely eliminated the positional nystagmus and vertigo produced by the involved (undermost) ear in the Hallpike maneuver. Following three singular neurectomies (3%), there was improvement but incomplete relief from the positional nystagmus. A sensorineural hearing loss caused by the singular neurectomies occurred in four patients (4%). A thorough knowledge of the surgical and histologic anatomy of the round window niche and singular canal, together with the use of local anesthesia to allow monitoring of a vestibular response to singular neurectomy are essential for effectiveness and safety.
在过去18年中，对95例后半规管感觉器官慢性嵴帽结石症患者实施了102例单孔神经切除术（SN）。7例患者接受了双侧序贯单孔神经切除术，88例患者接受了单侧单孔神经切除术。102例单孔神经切除术中的99例（97%）完全消除了Hallpike试验中受累（最下方）耳产生的位置性眼球震颤和眩晕。3例单孔神经切除术（3%）后，位置性眼球震颤有所改善但未完全缓解。4例患者（4%）因单孔神经切除术导致感音神经性听力损失。全面了解圆窗龛和单孔管的手术及组织学解剖结构，以及使用局部麻醉以监测单孔神经切除术的前庭反应，对于手术的有效性和安全性至关重要。
