ABSTRACT

The sublingual glands are almond-shaped structures located in the floor of the mouth, covered by mucosa in continuity with the mucosa of the ventral tongue and the gingiva of the mandible. The reflection of mucosa over the sublingual gland creates a fold known as the plica sublingualis on each side of the lingual frenulum. There may be several detached lobules of the sublingual gland, each with its own small duct that directly drains to the floor of the mouth. These small ducts are known as accessory ducts or ducts of Rivinus, some of which join to form the predominant sublingual duct (Bartholin’s duct).
