This communication study integrates composite multimodal research on postmortem human submandibular glands, based on macromorphometry. The normal ductographic sialograms were pairwise analyzed using linear morphometry, whole-gland planimetry and fractal properties, such as main duct length, caliber and tortuosities, side branches and accessory ducts/lobes. All the examined parameters presented a significant correlation, i.e., symmetry between the left and the right submandibular glands. The morphometric data presented can serve as a valuable reference in clinical practice.
