Sialoendoscopy as a treatment for an obstructed mandibular salivary duct in a horse

James S W Prutton et al. Can Vet J. 2016 Aug.

Abstract
in English, French

A 14-year-old Quarter Horse was examined for a draining tract of 8 months' duration on the right mandible that was non-responsive to antibiotic therapy and surgical therapy. Further investigation and subsequent treatment with sialoendoscopy and ultrasonography were performed to relieve an obstruction of plant awns in the mandibular salivary duct.

Sialo-endoscopie comme traitement pour un canal salivaire mandibulaire bloqué chez un cheval. Un cheval Quarter Horse âgé de 14 ans a été examiné pour une fistule purulente d’une durée de 8 mois à la mandibule droite qui ne répondait pas à la thérapie antibiotique et à la thérapie chirurgicale. De nouvelles investigations et le traitement subséquent à l’aide de la sialo-endoscopie et de l’échographie ont été réalisés pour éliminer un blocage du canal salivaire mandibulaire par des barbes de plantes.(Traduit par Isabelle Vallières).

Diagram depicting the location of salivary glands, ducts, and draining tract: 1. Parotid gland. Occupying the space between the caudal border of the mandible, the wing of the atlas, and the base of the ear. Ventrally it extends to the linguofacial vein. 2. Mandibular gland extends from the basihyoid to the atlantal fossa and is covered laterally by the parotid gland. 3. Buccal glands form 2 rows along the dorsal and ventral borders of the buccinator muscle. 4. Sublingual gland is directly under the oral mucosa between the tongue and the medial surface of the mandible from the level of the chin to about the third cheek tooth. 5. Parotid duct. The duct accompanies the facial artery and vein and opens into the oral vestibule opposite the 2nd or 3rd upper cheek tooth. 6. Mandibular duct opens on the floor of the mouth a few centimeters caudal to the incisors. 7. The sublingual gland has many small excretory ducts that open on small papillae below the tongue. 8. Chronic draining tract on the duct.
