颌面部海绵状血管瘤在临床中常见。浅层海绵状血管瘤累及皮肤或粘膜者采取液氮低温治疗或掺钕钇铝拓榴石激光治疗均能收到明显效果。病变较深,位于粘膜下的,掺钕钇铝拓榴石激光治疗亦具有透射能力,可以通过粘膜,使凝固破坏。但对颌下颈部等处深层海绵状血管瘤,表面皮肤色泽正常者,照射后皮肤形成疤痕而肿瘤消退不明显。如采取手术切除,由于有的病变组织范围较大没有明显界限,摘除困难,并 Maxillofacial cavernous hemangiomas are common in the clinic. Superficial cavernous hemangioma involving the skin or mucous membranes can be treated with cryogenic liquid nitrogen or neoadsorption laser treatment. The lesions are deeper and located under the mucous membranes. The laser treatment with neodymium-doped aluminum garnets also has the ability to transmit light through the mucous membranes and cause coagulation damage. However, in patients with deep cavernous hemangioma in the submandibular neck and the like, with normal skin color, the skin developed scars after irradiation and the tumor regression was not obvious. If surgical resection is performed, there are no obvious boundaries due to the large extent of diseased tissue, removal is difficult, and
