血管瘤多数发生于颌面皮肤、口腔粘膜、唇舌等组织。尤其唇舌部混合型血管瘤因其累及组织范围较广,术中出血机会较多。且颜面部缺损畸形若整复不当,易造成面部不同程度的畸形,以及因切除不彻底瘤组织残留而致再复发。故术中出血、瘤体组织的彻底清除和整复是手术成功与否的关键。 Hemangiomas occurred in maxillofacial skin, oral mucosa, lip and tongue and other tissues. In particular, the tongue and the tongue mixed hemangioma due to its involvement in a wide range of organizations, intraoperative bleeding opportunities more. And the facial defect if the defect is not properly reconstructed, easy to cause different degrees of facial deformity, and due to incomplete resection of tumor tissue caused by recurrence. Therefore, intraoperative bleeding, complete removal of tumor tissue and the restoration of surgery is the key to the success or failure.
