Objective To study the throat artery distribution of morphological characteristics of three-dimensional radiation therapy for throat cancer, laryngeal transplantation and repair of the larynx reconstruction of the anatomical basis. Methods 10 cases of throat specimens (1-10 specimens) the structural integrity of the throat specimen mold with hydrochloric acid corrosion, observe the throat artery branches, vernier caliper measurement of vascular warp; 20 patients (11 to 30 specimens) structural integrity over-vinyl chloride and barium sulfate mold, the United States GE Signa MR / i 1.5T whole body MR scanner and the German Siemens Somatom Esprit CT scan of the horizontal and sagittal throat vascular imaging data; Example (11 to No. 30 specimens) the structural integrity of the throat specimen mold, 1mm / sheet milling, to further determine the positional relationship between the throat of the artery and the surrounding organs and tissues, positioning Live throat blood vessels; 10 patients (31-40 specimens) artery mold throat specimens were observed under the stereomicroscope (coic xtl 23:7.5-30 times). Running quantitative analysis the throat artery branch distribution. Throat blood supply mainly from the superior thyroid artery and the inferior thyroid artery branch, the length of the left and right thyroid artery (4.2 ± 0.2) cm and (4.0 ± 0.2) cm, the starting point of the diameter of (1.5 ± 0.3) mm the length of the left and right thyroid artery superior thyroid artery choking after the separation of the seven main branches were the superior thyroid artery branch - branch, a major supplier of thyroid cysts and connective tissue, shallow position; (2.3 ± 0.27) cm and (2.2 ± 0.27) cm, the starting point of the diameter of (1.6 ± 0.37) mm, choking point caliber (1.4 ± 0.3) mm and (1.3 ± 0.3) mm. Scalene muscle along the front edge upward, rounded to the sixth cervical level, it turns sharply inward across the front of the longus and vertebral artery, jugular vein, carotid artery, the vagus nerve and sympathetic trunk rear to thyroid near the trailing edge at the midpoint of the steering down, after the separation of the four main branches of the inferior thyroid artery choking, thyroid artery branch - fourth branch to the thyroid, trachea and esophagus and other organs. Conclusion take the line features four different morphological research methods the throat artery branch distribution observation and analysis and quantitative research, the more detailed the throat artery walk the line size of the distribution and location of, and throat various parts of the vascular supply of . Laryngeal artery cast specimens in more detail clearly observed in the small branches of the artery course and distribution range, the artery and throat tissue relationship poor location, and MRI and CT scans to determine bit laryngeal artery and throat tissue structural organization of the positional relationship, but The fine structure of poor resolution, frozen mill milling method can be more intuitive display throat artery and the relationship of the different levels of the throat, play a very good complementary role of MRI and CT scan throat arteries, stereological study of laryngeal The arterial branch distribution of the number of quantitative Imaging techniques throat cancer three-dimensional radiation therapy, laryngeal transplantation and throat parts repair and reconstruction as an important adjunct to clinical diagnosis and imaging, more suitable for clinical.
