摘要
用50例正常人和10例唇腭裂头颈标本,做动脉照影和解剖观测。发现唇裂者的上唇动脉沿唇红缘和裂缘走行,终止于鼻翼基部(患侧)和鼻小柱基部(健侧)。双侧完全唇裂的人中部和切牙骨的动脉来自鼻中隔后动脉,筛前动脉,鼻翼动脉或鼻外侧动脉。正常腭部由腭大动脉,腭小动脉,鼻腭动脉,腭升动脉,咽升动脉和扁桃腺动脉供应。腭裂者腭大动脉不与鼻腭动脉吻合(患侧)。腭大动脉、腭升动脉不能与对侧同名动脉吻合,腭升动脉前支缩小,后支前移并沿裂缘前行,咽升动脉咽支不是循咽腭肌至软腭,而是从颅底沿腭帆提肌后内侧下行至软腭的鼻腔面。
50 cases normal head and neck specimen and 10 cleft of lip and palate were studied by dissection and arteriography.The results are as follow: 1.In the unilateral complete cleft lip,superior labial artery runs along the labial margin and cleft edge,ending in base of nasal wing on the lateral side.In the medial side,upper labial artery runs along labial margin and cleft edge,turning upward ending in the base of the columnella 2.In the bilateral complete cleft lip,the artery supply to the philtrum and premaxilla comes through posterior septal artery,anterior ethmoid artery,nasal alar artery and/or lateral nasal artery.3.normal palate region are supplied by six pair artery.They are greater palatine artery, lesser palatine artery,nasopalatine artery,ascending balatine artery, ascending pharyngeal artery and tonsillar artery.4.In cleft palate, anterior branch of the ascending palate artery has changed into small and has shifted to lateral side.posterior branch of the ascending palate artery has shifted forward and ran forward along with cleft edge.The present study found that palate branch of the ascending pharyngeal doesn′t run along with palato-pharyngeal muscle,but descend from base skull along with levator palate to the soft palate.
