Ultrasound-Guided Nd:YAG Laser Intervention in the Orofacial Region: Report of a Case of Multi-Focal Venous Malformation.

Venous malformation is acongenital vascular system structure malformation caused by abnormal vascular endothelial cell morphology, which can occur in any tissue or organ of the oral and maxillofacial region. Laser treatment is currently a commonly used minimally invasive treatment. In this case, the patient with congenital multiple venous malformation was treated with Nd:YAG laser for the visible submucosal part, and the subcutaneous part under the chin tip was treated with ultrasound. The chin tip was treated with ultrasound guided by the chair to achieve the purpose of minimally invasive laser treatment. In this case's diagnosis and treatment process, we hope to provide a new idea for laser treatment of oromaxillofacial vein malformations.
