Parotid gland relations

Parotid Gland Cancer . When tumors in the parotid gland are cancerous, they require removal and often additional treatment, as well. The close relationship of the parotid glands to the lymph system means cancer can spread easily from this location, so radiation and chemotherapy may be required if a tumor is cancerous.  As an exocrine gland, the parotid gland is composed of a lobular system of branching ducts that are separated by connective tissue septa. Like its fellow major salivary glands, the parotid gland is also surrounded by a dense connective tissue capsule. It also has a pseudocapsule arising from the deep investing layer of the cervical fascia

The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. It has superficial and deep lobes, separated by the facial nerve. The facial nerve and its branches pass through the parotid gland, as does the external carotid artery and retromandibular vein The upper end of the gland is in contact with the external acoustic meatus . Surfaces of the gland: 1- Lateral (superficial ) surface. 2- Anteromedial surface. 3- Posteromedial surface. 3. Divisions of Parotid Gland : Parotid gland is divided into 2 parts by the facial nerve : 1- superficial part . 2- deep part Parotid Gland. The important anatomic considerations in parotid masses take into account the surrounding muscles, bones, vessels, and nerves that come in contact with the gland. Also, the parotid capsule attachments will direct the spread of both benign and malignant tumors

Parotid gland: Anatomy, innervation and clinical aspects

About 80% of tumors of the parotid gland are benign. Surgical treatment of parotid gland tumors is sometimes difficult because of the anatomical relations of the facial nerve parotid lodge, as well as the increased potential for postoperative relapse. Thus, detection of early stages of a parotid tumor is extremely important. 84 The parotid gland is bisected by the facial nerve, dividing the gland into superficial and deep lobes. The facial nerve after entering the parotid gland splits into two main branches, the temporofacial and cervicofacial branches. This bifurcation is known as the Pes anserinus (Goose's foot) and divides to give rise to five other branches This video is about the parotid gland, its mould, presenting parts, relations, blood supply, secretomotor pathway, applied anatomy in detail. -----..

Salivary glands produce saliva to aid in chewing and digesting food. There are many salivary glands in the lips, cheeks, mouth and throat
  3. The parotid gland lies inferior to the zygomatic arch, anteroinferior to the external acoustic meatus, anterior to the mastoid process, and posterior to the ramus of the mandible. Relations. The parotid gland is enclosed in a sheath (parotid fascia) and is shaped roughly like an inverted pyramid, with three (or four) sides (fig. 48-2 A)
  4. The parotid gland is one of the major salivary glands. These glands make saliva. This is the watery substance used to lubricate your mouth and start the digestion process. The parotid gland wraps around the back of your lower jaw. From there, saliva travels through a tube called the parotid duct

The abnormal growth typically presents as slow-growing, solitary, unfixed neoplasm in the parotid area, although some are multinodular and fixed. Symptoms in most patients occur in a duration of less than a year up to several decades The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears.They are the largest of the salivary glands. Each parotid is wrapped around the mandibular ramus, and secretes serous saliva through the parotid duct into the mouth, to facilitate mastication and swallowing and to begin the digestion. Most common: p arotid gland → parotid carcinoma Less common locations Submandibular and sublingual glands : Neoplasms in these locations are less common compared to those in the parotid gland , but they are more frequently malignant ( ∼ 45% of submandibular and 70-90% of sublingual tumors) The parotid glands.
