Benign positional vertigo is a potentially disabling condition characterized by episodic vertigo following certain provocative head movements. In most patients it is self limiting; however, in a few it may prove intractable, causing considerable social morbidity. In these patients surgery may be considered. Surgery previously involved section of the vestibular or singular nerves, involving a significant risk to hearing and to the facial nerve. Ablation of the labyrinth may even be considered. The new surgical technique of occlusion of the posterior semicircular canal has proved to be curative in most patients with benign positional vertigo with little risk of hearing. This paper describes our experience of fenestration and occlusion of the posterior semicircular canal in four patients.
良性阵发性位置性眩晕是一种潜在的致残性疾病，其特征为特定诱发头部运动后出现发作性眩晕。大多数患者病情可自行缓解；然而，少数患者可能难以治愈，会导致相当大的社会功能障碍。对于这些患者可考虑手术治疗。以往的手术包括切断前庭神经或单神经，这对听力和面神经有很大风险。甚至可能会考虑进行迷路切除术。事实证明，后半规管阻塞这一新型手术技术可治愈大多数良性阵发性位置性眩晕患者，且听力受损风险很小。本文描述了我们对4例患者进行后半规管开窗和阻塞术的经验。
