What triangle is the submandibular gland in?

The submandibular gland is located in the submandibular triangle, below the mylohyoid muscle, with its posterior portion wrapped around the posterior border of the mylohyoid and extending anteriorly for a short distance.

What causes submandibular nodes to swell?

Swollen submandibular glands are usually caused by tiny stones blocking the ducts that channel saliva into the mouth. According to the Merck Manual, these stones can develop from the salts in saliva, especially if a person is dehydrated.

What is a Submaxillary triangle?

The submandibular triangle (or submaxillary or digastric triangle) corresponds to the region of the neck immediately beneath the body of the mandible.

Is submandibular and digastric triangle same?

The submandibular triangle, also known as digastric triangle, is located superior to the hyoid bone. It is bordered: posteriorly by the posterior belly of the digastric and stylohyoid muscles, and. anteriorly by the anterior belly of digastric muscle.

What does the submandibular triangle contain?

The submandibular triangle is located underneath the body of the mandible. It contains the submandibular gland (salivary), and lymph nodes. The facial artery and vein also pass through this area.

What is submandibular mass?

Submandibular triangle is a clinically important area in head and neck surgery practice and patients can present with isolated submandibular mass. The differential diagnoses of a submandibular mass include salivary gland pathologies, lymph node diseases, soft tissue problems, vascular and neuronal pathologies.

About 80 percent of salivary gland tumors start in these glands. About 75 percent of these tumors are benign (usually a type called pleomorphic adenomas) and 25 percent are malignant. Submandibular glands These are just under your mandible, or jaw bone, about halfway between your chin and your ear.

Where are the glands located in the submandibular triangle?

Major salivary glands include the paired parotid, submandibular, and sublingual glands.4 The parotid glands are wedge-shaped, located in front of the ear and the posterior surface of the mandible. These are the largest salivary glands and are covered by fascia and parotid capsule.

Where is the submandibular duct located in the mouth?

The mylohyoid muscle, a paired muscle that forms the floor of the mouth, separates a superficial and deep lobe in the gland. The submandibular duct, also called the Wharton’s duct, is the excretory duct of the gland. It drains saliva from the glands at the base of the tongue.

Where does the facial artery enter the submandibular triangle?

The facial artery (which is the fourth branch of the external carotid artery) also enters the submandibular triangle by passing beneath the posterior belly of the digastric muscle, as well as the stylohyoid muscle. Once it enters the triangle, it also lies deep to the submandibular gland.

What causes the submandibular gland to become swollen?

Submandibular glands can become swollen when small stones block the ducts that supply saliva to the mouth. Sometimes this can lead to an infection. The submandibular glands are the second largest of the three main salivary glands—about the size of a walnut. The two other types of salivary glands are the parotid (the largest) and sublingual glands.
