Parotid salivary gland is a human. A double-stranded structure, which is the maximum of the salivary glands. In order to facilitate swallowing and chewing and in order to initiate the absorption of starch, which is wound around the saliva and separated by a channel ramus Stensen in the oral cavity. The word “mumps” means around the ear (paraotic) literally. Under, parotid gland is a pair of serous salivary glands located in front of the ear canal to drain the secretions of their own in the vestibule of the mouth through the tube Stensen her. They are the major salivary glands of the largest of the human body.
Nflammation of one or both of the parotid gland is also known as the mumps. The most common cause of parotitis is mumps. A wide range of vaccination against mumps has reduced the incidence of measles mumps significantly. Regardless of external pressure and salivary duct stones from other infections viral infections, such as bacterial infections such separately, can cause (mumps, chronic suppurative parotiti or acute) the mumps as the cut-off channel . There is a possibility that syphilis and tuberculosis also cause granulomas formtation parotid gland. Main confluence of the main duct and stone occur in the main parotid duct. The saliva, when there is a tendency to avoid foods that produce this condition, patients usually complain of pain. In addition, you may want to become enlarged as trying to eat the parotid gland. Pain can be reproduced in the clinic squirting lemon juice in the mouth.
In surgery is a section of the oral mucosa and normal sphinterotomy to permit removal, the front of the channel depends to if the location of the stone, but if it is disposed on the back of the main duct, it must be completely resected glands There is a case to be. May be due to lymph benign lesions caused by Sjogren’s syndrome and Mikulicz disease is swelling of the parotid gland. Create and swelling of the parotid gland, the appearance of the line of heavy jaw, it indicates a failure bulimia nervosa, you may want to eat. 80% of eighty-tumor of the parotid gland are benign. The most common of these is (ie gland lymphoma) Warthin tumor and pleomorphic adenoma of many men than women. Its importance is related anatomically, it is a tendency to increase over time. The growth of the tumor, there is a potential to change the order of the gland, facial nerve causes facial pain on the side of traveling through the gland.
Mucoepidermoid cancer and tumor, 20% from 15 minutes of parotid gland tumor is adenoid cystic carcinoma of the most common malignant. Cancer of undifferentiated carcinoma parotid pleomorphic adenoma chemical cell carcinoma, cancer of EX, (pancreatic duct epithelial origin of parotid) glands, and, (resulting from real parotid gland) squamous cell carcinoma includes other cancers are. Critically, must be defined as a resection of the tumor is related to a branch of the facial nerve (CN VII), in the paralysis of the facial muscles of the face, as a result, there is a possibility of damage to the nerve. I increase the likelihood of recurrence after surgery and in some cases difficult anatomical relationship of the facial nerve parotid gland rental because of the surgical treatment of tumors of the parotid gland. Therefore, detection of early stages of parotid gland tumor is very important from the point of view of prognosis after surgery. Incomplete before treatment made in a range of other professional and cause attacks surgery technology is difficult.
Innervation is completely autonomous. Reached around gland periarterial plexus of the external carotid artery postganglionic sympathetic fibers from the superior cervical sympathetic ganglion, its main function is vasoconstriction. The cell bodies of preganglionic sympathetics, usually in the corner next to the spinal cord segment of the chest at the top. Sympathetic fibers in the glossopharyngeal nerve section before, I leave the brain stem of small salivary nucleus eardrum, through the next lower cone branch path to the otic ganglion then. They synapse to reach the gland hitchhiking through branch auriculotemporal nerve, mandibular nerve postganglionic fibers there.
