The objectives of this study were to evaluate the relationship between ductal morphometry and ramification patterns in the submandibular gland and pancreas in order to validate their common fractal dimension.
X-ray ductography with software-aided morphometry were obtained by injecting barium sulphate in the ducts of post-mortem submandibular gland and pancreas specimens harvested from 42 adult individuals.
Three cases were excluded from the study because of underlying pathology. There was a significant correlation between the length of the main pancreatic duct (MPD) and the intraglandular portion of the right submandibular duct (SMD) (r = 0.3616; p = 0.028), and left SMD (r = 0.595; p < 0.01), respectively, but their maximal diameters did not correlate (r = 0.139-0.311; p > 0.05). Both dimensions of the SMD showed a significant right-left correlation (p < 0.05). The number of MPD side branches (mean = 37) correlated with the number of side branches of left SMD, but not with the right one (mean = 9). Tortuosity was observed in 54% of the MPD, 32% of the right SMD, and 24% of the left SMD, with mutual association only between the two salivary glands.
Although the length of intraglandular SMD and MPD correlate, other morphometric ductal features do not, thus suggesting a more complex relationship between the two digestive glands.
本研究旨在评估下颌下腺和胰腺导管形态测量和分支模式之间的关系，以验证它们的共同分形维数。
通过向死后的下颌下腺和胰腺标本的导管中注入硫酸钡，获得 X 射线导管造影并进行软件辅助形态测量。
由于潜在的病理学原因，有 3 例病例被排除在研究之外。主胰管（MPD）的长度与右下颌下腺导管（SMD）的腺内部分（r = 0.3616；p = 0.028）以及左 SMD（r = 0.595；p < 0.01）之间存在显著相关性，但它们的最大直径没有相关性（r = 0.139-0.311；p > 0.05）。SMD 的两个维度均显示出显著的左右相关性（p < 0.05）。MPD 侧支的数量（平均值= 37）与左 SMD 的侧支数量相关，但与右 SMD 无关（平均值= 9）。MPD、右 SMD 和左 SMD 的迂曲率分别为 54%、32%和 24%，仅在这两个唾液腺之间存在相互关联。
尽管 SMD 内腺和 MPD 的长度相关，但其他形态测量导管特征不相关，这表明这两个消化腺之间存在更复杂的关系。
