Objective Superficial teleangiectasia can be efficiently treated with a 532 nm KTP laser. The recently developed lithium-borate (LBO) lasers are characterized by producing identical wavelengths for the same clinical indications whilst providing higher energy. In this study, telangiectasia, hemangiomas and other superficial vascular changes of the skin were subjected to treatment with a recently developed 532 nm LBO laser to evaluate its effectiveness.
Patients and method Outpatients of the department for lasers and aesthetics at a tertiary university hospital were included in an intervention study. The effectiveness of the 532 nm LBO laser treatment of telangiectasia, hemangiomas and other superficial vascular changes of the skin was evaluated in a before/after trial. The number of treatments which was necessary for full clearance of the lesions was determined.
Results A total of 125 patients, aged between 5 and 75 years, and predominantly of skin type II, were subjected to 271 treatments. Patients reported low pain and a high degree of comfort during therapy when using hydrogel pads for cooling. In 80% of the cases, one treatment alone was sufficient to cure the lesion.
Conclusion The 532 nm LBO laser is easy to use and has been proven to be reliable, stable and efficient in the treatment of superficial vascular conditions.
