摘　　要：目的为单侧完全性唇腭裂胎儿宫内手术修复提供解剖学基础。方法制作和观察21～32周正常和单侧完全性唇腭裂胎儿头颈部血管铸型标本,比较它们颌面部血供的来源及吻合情况。结果①正常胎儿颌面部血供主要来源于面动脉、颏下动脉、下唇动脉、上唇动脉、鼻翼下缘动脉、鼻翼动脉、鼻外侧动脉、鼻背动脉、眶下动脉及面横动脉等,这些动脉及其分支构筑颌面部组织丰富的血管网;②单侧完全性唇腭裂胎儿患侧上唇动脉沿裂缘向上至鼻翼基底部与鼻翼下缘动脉等相吻合,患侧部分腭骨缺损暴露的腭大动脉穿过骨残端与患侧鼻腔内的血管相吻合。结论对单侧完全性唇腭裂胎儿颌面部进行宫内修复手术,重点在鼻部和上唇部的血供,主要以上唇动脉、鼻翼下缘动脉和腭大动脉为主。Objective To provide anatomic basis of intrauterine surgical repair in unilateral complete cleft lip and palate fetus.Methods The head and neck vascular cast specimens of 21-32 weeks normal and unilateral complete cleft lip and palate were made and observed,which maxillofacial region＇s blood supply source and arterial anastomosis were compared.Results ①For the normal fetus,the maxillofacial region＇s blood supply mainly came from facial artery,submental artery,inferior labial artery,superior labial artery,lower edge nasal alar artery,nasal alar artery,lateral nasal artery,dorsal nasal artery,infraorbiatal artery and transverse facial artery,which to build the rich vascular network.②For the fetus with unilateral complete cleft lip and palate,the affected side of superior labial artery walked along cleft border up to the anastomosis with lower edge nasal alar artery by the basis of nasal alar artery.The affected side of greater palatine artery and nasal vessel were formd in the anastomosis by bone stump.Conclusion When the intrauterine surgical repair of unilateral complete cleft lip and palate is performed,the emphasis of blood supply are on the nose and upper lip region,which are mainly in superior labial artery,lower edge nasal alar artery and greater palatine artery.
