BACKGROUND:Infantile hemangioma (IH) can lead to severe complications. The 595-nm pulsed dye laser is poorly effective on thick and deep IH. Long-pulsed alexandrite laser has the proper wavelength of 755 nm and a relatively deep penetration. Thus, this may be a safe and effective treatment method for relatively deep or thick IH.
AIMS AND OBJECTIVES:This study aims to determine whether 595-nm pulsed dye laser and 755-nm long-pulsed alexandrite laser in sequential therapy are safer and more effective for relatively deep or thick hemangioma.
MATERIALS AND METHODS:This was a prospective study. A total of 194 infantile IH patients (thickness greater than 2 mm and less than 8 mm) were randomly divided into two groups: control group (treated using 595-nm pulsed dye laser) and experimental group (treated by sequential therapy with 755-nm long-pulsed alexandrite laser and 595-nm dye laser).
RESULTS:The control group had a total effective rate of 36.1%, while the experimental group had a total effective rate of 76.3%. Enumeration data were compared by X2 -test. The results were considered statistically significant at P < .05.
CONCLUSION:Sequential therapy with 755-nm pulsed dye laser and 595-nm long-pulsed alexandrite laser is a safe and effective treatment approach for relatively deep or thick hemangioma.
