All these peculiaritiesare siraj^le when the topography of the sublingual gland isconsidered, and depend on the part of the gland attackedby the chronic interstitial inflammation. If both glands areattacked by this inflammation, cysts will develop more orless symmetrically on both sides of the frenum. Occasion-ally, but rarely, cysts are truly median, and may lie closeto the alveolus of the jaw. In these cases it is not the sub-. FiG. 184.—Sarcoma of the Parotid Gland.

(Thegrandula incisiva lies in the middle line of the floor of themouth, immediately behind the incisor teeth.) Treatment.—The treatment of ranula consists in theevacuation of the cyst by incision, and the establishment ofan orifice, so that the fluid secreted by the gland may bepermitted to escape into the oral cavity as it makes itsescape from the gland. The method of operation is to in-cise the sac from end to end or to make the opening so large DISEASES OF THE SALIVARY GLANDS 375 that it cannot close during repair, thus making the cavityof the sac a part of the oral cavity. The mucous membraneand the wall of the sac are sutured throughout with ten-day catgut to i^revent closure. Other methods of treat-ment have been introduced. Chlorid of zinc in solution ha
