Curative effect of Cynergy dual wavelength laser in treatment of skin vascular pathological changes in children / 中华医学美学美容杂志

ABSTRACT

Objective To explore the curative effect and adverse reactions through Cynergy dual wavelength laser to cure skin vascular pathological changes in children.Methods Cynergy dual wavelength (595 nm and 1064 nm) laser were used to treat the skin vascular pathological changes in children (650 cases) including strawberry-shaped hemangioma (398 cases) and port wine stain (252 cases).Anergy density was 5-15 J/cm2 and 30-80 J/cm2.The curative effect and adverse reaction and also the relationship between the port wine stain curative effect and the age of patient,location,and colour of skin lesions were analyzed.Results In total 650 cases after 3-7 times treatments under suitable pulse width and energy density,the curative effect for strawberry-shaped hemangioma was 92.2 ％,that for pink type port wine stain was 77.9 ％,that for purple type port wine stain was 38.9 ％,and that for thickening type port wine stain was 14.3 ％ ; the overall adverse reaction rate was 2.3 ％.After test with x2 analysis,the curative effect of port wine stain also varied depending on the age of patient,location,and colour of skin lesions.The younger the age of patient and shallower of colour of skin lesions,and the better the curative effect.The curative effect for location around the eyes was better than frontal face and limbs.Conclusions Application of Cynergy dual wavelength laser in treatment of the skin vascular pathological changes in children has notable curative effect and low adverse reaction.It is a new curative technology and also safe and reliable.It is worthy of popularization and application.
