在采用上颌骨切开术以矫正颅面畸形时,常需分离上颌骨与翼板之间的联接,而使面中份前移。为避免术中损伤颌内动脉引起出血,作者研究了翼腭凹区的有关解剖和手术方法。翼颌联接的上方是翼腭凹,颌内动脉行经下颌骨髁状突后份绕行向内侧在翼腭凹的上方进入翼腭凹。在横过翼腭凹时分出一些终末支。如果面中部松动术发生急速出血多数是损伤颌内动脉主干或其分支。翼腭凹内
In the use of maxillary incision to correct craniofacial deformity, often need to separate the connection between the maxilla and the wing, leaving the surface area forward. In order to avoid intraoperative injury of the maxillary artery causing bleeding, the author studied the pterygopalatine anatomy and surgical approach. Above the wing jaw joint is the pterygopalatine, the maxillary artery passes through the mandibular condyle followed by the bypass to the medial side of the pterygopalatosis above the wing palate. Divide the wing cleft palate concave when the number of terminal branch. If the surface of the central loosening occurred in the majority of rapid bleeding is to damage the main artery or branch of the internal carotid artery. Wing palate concave
