Applicatim of high frequency sonography in laser treatment of children facial subcutaneous cavernous hemangiomas / 中华超声影像学杂志

ABSTRACT

Objective　To apply high frequency ultrasound to laser treatment of children facial subcutaneous cavernous hemangiomas.Methods　Ten children with facial subcutaneous hemangiomas were treated with NdYAG laser, the process was supervised with high frequency ultrasound.Results　Before treatment,tumors showed low and inhomogenous echogenicity with blood flow signal;after treatment,the tumors appeared high and homogenous echogenicity with little or no blood flow signal. Conclusions　The high frequency ultrasound is helpful for laser treatment of facial subcutaneous cavernous hemangiomas in preoperative location and postoperative assessment.
