Abstract

The anatomy of horse salivary glands was studied on cadaver heads. The mandibular duct enters the oral cavity on the border of sublingual caruncle. The parotid gland duct enters the oral cavity on the cheek opposite the upper 4th premolar (3rd cheek tooth). Prior to applying sialography to live animals the techniques of catheterization, injection and radiography had to be carried out on cadaver heads. The techniques were subsequently applied to three live animals. The animals were anesthetized routinely and the mandibular and parotid ducts
catheterized, and contrast medium was injected into each gland. Lateral radiographs were made immediately after the injection. The normal horse mandibular and parotid salivary glands as depicted on sialograms have a multilobular appearance in cadaver heads, but in live animals the outline of gland, main ducts and their smaller branches could be identifi ed. The parotid duct leaves the deep surface of the rostral end of gland and courses along the border of the masseter muscle before it enters the mouth. The mean diameter of parotid duct was 3.9 ± 0.9 mm. The mandibular duct leaves the rostral end of the gland, its mean diameter being 3.6 ± 1.2 mm. In conclusion, sialography of mandibular and parotid salivary gland in horse is practical and helpful in diagnoses of pathological conditions of these glands and their ducts.
