治疗皮肤色素病变，特别是真皮深层色素沉着，很难达到满意的结果而没有并发症。为了治疗太田痣、先天性痣等皮肤色素沉着，我们尝试了激光表面置换（CO2）和选择性光热解激光（q -开关红宝石激光[QSRL]）联合治疗，并与单独使用QSRL治疗的结果进行了比较。自1995年以来，对47例太田痣患者进行了联合激光治疗。平均治疗时间6个月，平均治疗次数5次。47例患者中，46例（98%）表现良好。采用激光联合治疗先天性痣15例，12例（80%）疗效良好。通过结合表面置换和选择性激光，治疗周期缩短了2 - 3个月，治疗次数减少了2 - 3倍。此外，治疗先天性痣已成为可能，这是没有单独的QSRL的情况下。Er:YAG激光可以代替CO2激光用于表面修复，因为它造成的热损伤更小，伤口愈合更快。
Treating pigmented lesions of the skin, especially deep dermal pigmentations, are difficult to achieve satisfactory results without complications. To treat dermal pigmentations, such as nevus of Ota and congenital nevus, the combined therapy of a resurfacing laser (CO2) and a selective photothermolytic laser (the Q-Switched Ruby Laser [QSRL]) was tried, and the results were compared with those treated with the QSRL alone. Combined laser therapy has been performed in 47 patients with nevus of Ota since 1995. The mean treatment period was 6 months and the mean number of treatment was five. Of 47 patients, 46 (98%) showed excellent results. To treat congenital nevus, combined laser therapy was used in 15 patients, and 12 (80%) showed good to excellent results. By combining resurfacing and selective lasers, the treatment period has been reduced by 2 to 3 months, and the number of treatments has been reduced two- to threefold. Furthermore, treatment of congenital nevus has become possible, which was not the case with the QSRL alone. The Er:YAG laser can be used for resurfacing instead of the CO2 laser because it causes less thermal damage and faster wound healing.
