Sublingual region

Sublingual region (regio sublingualis) is located between the bottom surface of the front two-thirds of the tongue, mucous membrane polostr mouth and internal surfaces of the body of the mandible and the bottom is limited aperture oral - oral sublingual muscle (m. mylohyoideus).
Within sublingual region lie sublingual salivary gland ducts, channels submandibular glands, chin-speaking, sublingual-speaking and the French speaking (mm. genioglossus, hyoglossus, styloglossus) muscles, speaking vessels (a. et v. lingualis), sublingual artery and vein (a. et v. sublingualis), speaking and sublingual nerves (nn. lingualis, hypoglossus), lymph nodes and the tissue surrounding these education. Through tissue and lymphatic ways this area is connected with the submandibular, popodrobnei areas, kryloviana-jaw, okoloplodna spaces and areas neck (printing. Fig. 2).

Pathology. In sublingual region are usually more isolated abscesses maxillo-speaking groove (sulcus mandibulolingualis), located between the inner surface of the body of the mandible, within the lower molars, and posterolateral surface of the tongue and with the other hand; less commonly, there are abscesses sublingual roller, phlegmon of the floor of mouth (see Ludwig's Angina), mucus retention cysts (see Ranula), cysts salivary glands and a dermoid cyst.
When the abscess maxillo-speaking groove cut a length of 3-4 cm from the mouth cut through the mucosa and submucosa, and then in the area of abscess penetrate stupid way. The operation ends with an introduction to wound rubber strips. To avoid injuries lingual nerve and submandibular duct cancer, the intersection of which is located on the second lower molar, making the cut, you should keep close to the inner surface of the body of the mandible.
Long-term conservative treatment and delay in operation may cause the spread of inflammatory process in more deep superficial tissues. When the abscess bottom of the mouth due to laryngeal edema can occur asphyxia, so the surgeon must be ready for operation tracheotomy (see).
Treatment retention and dermoid cysts operational, consisting in total removal of them. Cysts sublingual salivary cancer often give relapse, so retry operation, remove the tumor with gland.
