对26例舌的血管构筑用墨汁灌注血管造影碱性磷酸酶及扫描电镜等方法进行较全面系统的观察.本内容系手术显微镜下所见的一部分.舌动脉于舌骨大角处直接起自颈外动脉者多见,其中有25%与面动脉共干起始.起始外径:2.5±0.3mm(2.2～3.2)前行发出舌下动脉后移行于舌深动脉.舌深动脉与舌骨舌肌的局部关系较为恒定,它是舌动脉的直接延续,故其外径变化不明显2.3±0.3mm(2.0～3.1).舌深动脉是看血供的主要血管由后往前至舌尖邻近多以鸦爪状而终,终止处距舌下钱面:2.6±0.6mm(1.8～3.7);其形态特点是行程迂曲明显由后向前与主干几呈直角向上依次分出13.9长支(8～18)至舌背以及不恒定的向下行的小支3支(1～5)至舌底.左右侧舌深动脉分别行于同侧舌肌内未见有跨越正中纤维隔,在舌尖偶可见吻合.舌静脉在解剖观察中就其形成行径和注入个体差异较大,但有二点似较明显:一是舌动脉伴行静脉都较纤细未见有管径大于动脉者;二是舌下神经伴行静脉绝大部分均能见到位于舌下壁的局部位置也相对恒定,从外观可认为是舌引流的主要静脉.从舌位于口腔中特有局部位置有较厚的肌肉和良好的血供舌粘膜下的丰富血管丛,以及舌蒂瓣是口腔内的组织,具有自然的适应性对口腔既有唾液又有细菌的复杂环境将会有较好的抗感染能力等条件.可见口?
26 cases of tongue of blood vessels with ink perfusion angiography alkaline phosphatase and scanning electron microscopy and other methods to conduct a more comprehensive and systematic observation of the contents of the surgical microscope under the part of the tongue arteries directly from the neck External arteries are more common, of which 25% and surface arteries start together. Initial diameter: 2.5 ± 0.3mm (2.2 ~ 3.2) issued after the sublingual artery migrate to the deep arteria. The local relationship of the tongue muscle is relatively constant, it is a direct continuation of the lingual arteries, so its diameter did not change significantly 2.3 ± 0.3mm (2.0 ~ 3.1) .The deep arteries of the tongue is to look at the main blood supply from the back to the tip of the tongue Near the majority of the crow claw-like end, terminating from the sublingual money: 2.6 ± 0.6mm (1.8 ~ 3.7); its morphological characteristics of the journey tortuous obviously from the back to the front and the trunk a few were at right angles up 13.9 long branches (8 ~ 18) to the dorsum of the tongue, and 3 branches (1 ~ 5) of the lesser branches down to the tongue.The left and right lingual deep arteries did not cross the median fiber in the ipsilateral lingual muscle, Tongue tongue can be seen even coincidence tongue veins in the anatomical observation of its formation and injection of larger individual differences, but there are two more obvious as follows: one Tongue arteries with vein are more slender than the arteries have no diameter; Second, most of the hypoglossal nerve accompanied by veins can be seen in the sublingual wall of the local location is relatively constant, from the appearance of the tongue drainage can be considered Of the main vein from the tongue located in the mouth of the local special thicker muscles and a good blood supply to the tongue of the rich submucosal vascular plexus and tongue flap is the oral tissue with natural adaptability of both oral saliva There are bacteria in the complex environment will have better anti-infective conditions.
