目的研究喉部动脉分布的形态学特点,为喉部肿瘤的三维放射治疗、喉移植及喉部修复重建提供解剖学基础。方法 (1)10例(男,女各5)结构完整的喉部标本铸型,用盐酸腐蚀,观察喉部动脉分支,游标卡尺测量血管粗细大小;(2)20例(男,女各10)结构完整的喉部标本用过氯乙稀和硫酸钡混合铸型,采用美国GE Signa MR/i型1.5T等全身MR扫描仪进行水平面和矢状面的扫描,获得得到喉部血管的的影像学数据;(3)20例(男,女各10)结构完整的喉部标本铸型,进行1mm/片磨铣,进一步确定喉部动脉与周围器官组织的位置关系,对供应喉部血液的血管进行定位分析;10例(男,女各5)动脉铸型的喉部标本在体视显微镜(coic xtl 23:7.5-30倍)下进行观察。对喉部动脉分支分布走行进行分析定量。结果喉部血供主要来自甲状腺上动脉和甲状腺下动脉分支,左、右甲状腺上动脉的长度为(4.2±0.2)cm和(4.0±0.2)cm,起始点的口径为(1.5±0.3cm),甲状腺上动脉入喉后分出7个主要分支,分别为甲状腺上动脉第1分支--第7分支;左、右甲状腺下动脉的长度为(2.3±0.27)cmm和(2.2±0.27cmm),起始点的口径为(1.6±0.37)mm,入喉点口径为(1.4±0.3)mm和(1.3±0.3)mm。甲状腺下动脉入喉后分出4个主要分支,分别为甲状腺上动脉第1分支--第4分支。结论采用这4种不同的形态学研究方法对喉部动脉分支分布走行特点的观察分析和定量研究,较详细的获得了喉部动脉的走行分布大小及分布位置,以及喉各部位的血管分布情况。
Objective To study the morphological characteristics of laryngeal artery distribution and provide anatomical basis for three-dimensional radiotherapy, laryngeal transplantation and laryngeal reconstruction in throat tumors. (2) 20 cases (10 males and 10 females) were enrolled in this study. Methods: (1) 10 cases (5 male and 5 female) of throat specimens with complete structure were treated with hydrochloric acid to observe the branches of the laryngeal artery and caliper. Thoroughly structured throat specimens were mixed with a mixture of vinyl chloride and barium sulphate and scanned using horizontal and sagittal planes using a whole body MR scanner such as the GE Signa MR / i 1.5T from the United States to obtain images of the laryngeal vessels (3) Twenty specimens (10 males and 10 females) with a complete structure were processed with 1mm / piece milling and milling to further confirm the relationship between the laryngeal arteries and the surrounding organs and tissues. Vascular localization analysis; throat specimens of 10 cases (5 male and 5 female) of arteries were observed under a stereomicroscope (coic xtl 23: 7.5-30). Thoracic artery branch of the distribution of travel analysis and quantification. Results The laryngeal blood supply mainly came from the branches of the thyroid artery and the thyroid artery. The lengths of the left and right thyroid arteries were (4.2 ± 0.2) cm and (4.0 ± 0.2) cm, and the diameter of the starting point was (1.5 ± 0.3cm) , The thyroid artery into the throat after the separation of the seven main branches, respectively, the first branch of the thyroid artery - the seventh branch; left and right thyroid artery length (2.3 ± 0.27) cmm and (2.2 ± 0.27cmm) (1.6 ± 0.37) mm at the starting point and (1.4 ± 0.3) mm and (1.3 ± 0.3) mm at the entry point. Thyroid artery into the throat after the separation of the four main branches, respectively, the first branch of the thyroid artery - fourth branch. Conclusions The four different morphological methods were used to observe and analyze the characteristics of the branch of the laryngeal arteries. The distribution of the walking distribution and the distribution of the laryngeal arteries and the distribution of blood vessels in different parts of the larynx were obtained in detail .
