Abstract

There have been some reports on the use of KTP laser for sublimis and small hemangioma in the oral region. In the case reported in this paper, a relatively large and deep-seated hemangioma of the retromolar and buccal region was treated with photo-coagulation by KTP laser.<BR>The KTP laser is a pure green light in the visible portion (532 nm) of the electromagnetic spectrum. It has unique characteristics such as high absorption by hemoglobin, negligible absorption by water and a relatively shallow depth of penetration, which are ideal for the photo-coagulation of hemangioma. In this case, the tumor disappeared by performing photo-coagulation one time and bleeding was not encountered during the operation. The results suggested that KTP laser is effective for the treatment of relatively large and deep-seated hemangioma.
