DILATED SALIVARY DUCTS. SALIVARY CALCULUS. SALIVARY FISTULA.
These are all surgical diseases and are to a large extent inter dependent. The impaction of the calculus in the duct leads to overdistension of the duct posterior to the obstruction, and the rupture or incision of the distended duct, determines the fistula. It is only necessary here to point out the seat of these lesions: the distended sublingual ducts constituting a more or less rounded swelling to one side of the frænum lingui, the Whartonian duct forming a tense rounded cord from the papilla back of the lower incisor teeth backward on the inner side of the lower jaw, and the Stenonian duct forming a similar tense cord from near the middle of the cheek down around the lower border of the jaw in company with the submaxillary artery and backward on the inner side of its curved border to the parotid gland.
For the more precise lesions, symptoms and treatment of these, see a work on surgery.
