 note = {Three cases of hemangiomas in the oral region which were treated with photo-coagulation by KTP laser were reported. The KTP laser is a pure green light in the visible portion (532nm) of the electromagnetic spectrum and has unique characteristics such as high absorption by hemoglobin, negligible absorption by water and a relatively shallow depth of penetration, which are ideal for photo-coagulation of hemangioma. The first case was a 38-year-old female with a superficial hemangioma of the upper lip. The second case was a 43-year-old female with a superficial hemangioma of the lower lip. The third case was a 55-year-old male with multiple hemangiomas of the lips, right cheek and tongue. With the patients under local anesthesia, the hemangiomas were treated with 1.5 w of KTP laser irradiation. In the first two cases, the tumors completely disappeared with very mild scarrings postoperatively. In the case with multiple hemangiomas, the superficial portions of the hemangiomas decreased in size and spontaneous bleeding was not encountered, but the deeper portions remain unchanged. The results suggested that the KTP laser is effective for the treatment of superficial hemangioma., KTPレーザーによる光凝固療法を施行した口腔内血管腫の3例を報告する。KTPレーザーは、波長532nmの緑色可視光で、へモグロビンに極めて良く吸収され、水にほとんど吸収されず、組織浸透度が比較的浅いという特性を持ち、血管腫の光凝固に適している｡症例1は、38歳女性で、上唇に表在性の血管腫を認めた｡症例2は、43歳女性で、下唇に表在性の血管腫を認めた｡症例3は、55歳男性で、上下唇、右側頬部および舌に多発性の血管腫を認めた。治療は、局所麻酔下に出力1.5W のKTPレーザーを血管腫全体に連続照射した｡2例の表在性血管腫は、術後消失し、瘢痕形成も軽度であった。症例3では,深部の血管腫には効果がなかったものの、表在性の部分では腫瘍が減量され、表面からの出血も術後は認めなくなった。以上の結果から、KTPレーザーによる光凝固療法は、表在性の血管腫に対する効果的な治療法となりうることが示唆された｡},
