The results of long-term follow-up after surgical treatment of two patients with intractable benign paroxysmal positional vertigo are reported. Argon laser irradiation of the blue-lined posterior and lateral semicircular canals in one patient, and of only the posterior canal in the other was performed seven and six years ago, respectively. Argon laser irradiation was carried out 10 times in succession three mm along the canal to occlude it. The power applied each time was 1.5 W on the dial of the laser device for 0.5 sec. Relief of vertigo was noted on the second post-irradiation day. There has been no recurrence of vertigo in these patients.
报告了两名顽固性良性阵发性位置性眩晕患者手术治疗后的长期随访结果。分别在7年前和6年前，对一名患者的蓝色标线后和外侧半规管进行氩激光照射，对另一名患者仅对后管进行氩激光照射。沿半规管连续10次进行氩激光照射，每次照射距离为3毫米以闭塞半规管。每次照射时激光设备表盘上的功率为1.5瓦，持续0.5秒。照射后第二天眩晕症状减轻。这些患者眩晕未再复发。
