1口腔颌面部软组织损伤口腔颌面部软组织血循环丰富,组织相对较为疏松,软组织伤后出血较多,水肿明显。同时,由于血循环丰富,口腔颌面部组织抗感染能力较强,组织存活能力亦较强。面部软组织伤后可能遗留面部畸形,对患者容貌和心理可能产生重要影响。因此,治疗口腔颌面部软组织损伤时应考虑上述解剖生理特点。 1 oral and maxillofacial soft tissue injury Oral and maxillofacial soft tissue blood circulation is rich, relatively loose tissue, soft tissue injury more bleeding, edema. At the same time, due to rich blood circulation, oral and maxillofacial tissue anti-infective ability, tissue survivability is also strong. Facial soft tissue injury may leave facial deformity, the patient’s appearance and psychological may have a significant impact. Therefore, the treatment of oral and maxillofacial soft tissue injury should consider the anatomical and physiological characteristics.
