摘要
为了探索应用上唇动脉为蒂的逆行鼻唇沟皮瓣的可能性，采用８例成人尸体标本，进行显微解剖，观察上唇动脉的走行与鼻唇沟区皮肤血供的关系。结果，上唇动脉由面动脉在口角外约１０ｍｍ处由鼻翼外侧连线下２／３发出，上唇动脉出现率１００％，起始处外径（０．８±０．１）ｍｍ，主干长达９０ｍｍ。双侧上唇动脉在中线相互交通形成弓形动脉，该动脉走行于距红唇缘深面约６ｍｍ的粘膜下组织内，动脉有恒定的伴行静脉。在一侧上唇动脉起始处切断同侧面动脉近心端，可由对侧面动脉通过上唇动脉供应鼻唇沟区域血运。为临床应用上唇动脉为蒂的逆行鼻唇沟岛状皮瓣。
In order to study the feasibiliy of the insular skin flap of the nasolabial groove with the retrograde superior labial artery, 8 adult cadavers were dissected and the relation between the superior labial artery and the skin of nasolabial groove was observed, The result revealed that superior labial artery was one of the branches of the facial artery and could be found in every cadaver. The diameter of the artery was 0.8±0.1 mm and the length was about 90 mm. The left and right facial arteries were connected with each other in the mid line in the formation of the arcuate artery. The arcuate artery lay within the submucous tissue beyond the vermilion border about 6 mm. The concomitant veins were constant. If the facial artery being sectioned was beyond its initial site of superior labial artery, the skin of nasolabial groove on the same side could receive blood supply from contralateral supperior labial artery. The conclusion was that the insular skin flap of the nasolabial groove with the retrograde superior labial artery could be used in patients, because it had support from anatomical research.
