The Hexascan is an automated scanning laser handpiece originally developed to treat port-wine stains. It can be adapted to operate with most continuous wave laser systems delivering a variety of visible wavelengths.
To review the use of Hexascan with 585-nm yellow dye laser light for cutaneous vascular disorders and 514-nm green argon light for benign cutaneous melanocytic disorders.
The current clinical results, treatment parameters, indications, limitations, and complications of these procedures are discussed in a review format. In addition, a new clinical study of benign lentigines treated with green laser light is presented.
Most benign lentigines showed considerable lightening or complete disappearance after one or two treatments. Other melanocytic disorders may also respond. Deep dermal lesions such as Nevus of Ota may be totally unresponsive. Both vascular malformations such as port-wine stains and hemangiomas are also treatable.
The Hexascan device attached to a continuous wave tunable dye laser can successfully treat a wide variety of cutaneous vascular and melanocytic disorders in both infants and adults.
Hexascan是一种最初为治疗葡萄酒色斑而开发的自动扫描激光手持装置。它可以适配大多数能发出多种可见波长的连续波激光系统进行操作。
回顾Hexascan结合585纳米黄色染料激光治疗皮肤血管疾病以及结合514纳米绿色氩激光治疗良性皮肤黑素细胞疾病的应用情况。
以综述的形式讨论这些治疗方法目前的临床结果、治疗参数、适应证、局限性和并发症。此外，还展示了一项用绿色激光治疗良性雀斑的新临床研究。
大多数良性雀斑在一两次治疗后显示出明显变淡或完全消失。其他黑素细胞疾病也可能有反应。太田痣等真皮深层病变可能完全没有反应。葡萄酒色斑和血管瘤等血管畸形也可治疗。
连接到连续波可调染料激光的Hexascan装置能够成功治疗婴儿和成人的多种皮肤血管和黑素细胞疾病。
