Sublingual gland

Sublingual gland (glandula sublingualis) - steam room salivary gland. Is located in the front section of the bottom of the mouth on both sides of frenulum of tongue (printing. Fig. 2 and 3). Sublingual gland oblong form, surrounded by loose fiber and lies on oral sublingual muscle (m. mylohyoideus). Raised mucous membrane above gland produces sublingual fold (plica sublingualis). Along the top is the inner surface of the sublingual gland passes excretory duct of submandibular salivary glands. The main excretory duct P. W. (ductus sublingualis major) opens at sublingual papilla - pulp (caruncula sublingualis) near the mouth of the submandibular duct (ductus submandibularis) or runs into it. In addition, there are several small excretory ducts (ductus sublingualis minores)opening onto sublingual fold.

The blood supply of the sublingual gland exercise speaking (a. lingualis) and chin (a. submentalis) artery. Vienna P. W. fall into facial vein (v. facialis).
Parasympathetic fibers gland to go as a part of the lingual nerve (n. lingualis), and sympathetic - of-plexus caroticus externus.
Damage P. W. rarely lead to significant pathological condition, sometimes formed salivary cysts.
Cysts sublingual gland developed with the obliteration of one of the ducts after injury or transferred inflammatory process. Ranula (see) is also a kind of salivary cysts P. W. Treatment of cysts surgical; cysts considerable size is removed along with salivary gland.
Clonakenny disease in P. W. there is a very rare. In a typical clinical picture of this disease in the first place it is necessary to exclude him from the submandibular salivary gland (see Sialolithiasis). For differential diagnosis apply a contrast radiography (see Sialography).
Tumor P. W. there are also rare, they can be benign (adenodentate, adenoma, mixed tumor and others) and malignant (adenocarcinoma, cilindrata).
Benign tumors are removed often with gland. In malignant tumors combination therapies - removal of the tumor in a wide range and radiation therapy.
X-ray picture of stones sublingual gland. Stones sublingual gland on x-rays have the appearance of shadows oblong or round shape of different intensity. To identify stones do the pictures in the side, straight, axial or other projections (see X-ray projection to x-rays), trying to separate the shadow of stone from the shadows of the lower jaw. It is advisable to make intraoral axial images. To detect stones, not giving shade on x-rays, used sialography in the same projections. On salagrama stones, surrounded by contrast agent, provides a picture of filling defect. Sialography allows you to set the changes caused in the salivary duct, and to distinguish stones P. W. from stones submandibular duct cancer. Correctly made x-ray examination gives the opportunity not only to detect stones sublingual gland, but also to establish the number, size, shape, and the exact location that is important for surgical treatment.
