Lymph nodes of the submandibular region are located in the space between the mandible (lower jawbone) and the submandibular salivary glands (found under the tongue). The salivary gland occasionally contains one or more lymph nodes that are deeply entrenched. In a healthy adult, the submandibular lymph nodes are typically less than 1 centimeter in size. The length of the submandibular duct, which transports lymph fluid to the lymph node, is around 5 to 6 cm in the mature individual.
Right Submandibular Lymph nodes
The right submandibular lymph nodes can be found beneath the mandible (jawbone) on the right side, close to the jaw's angle. They are accountable for the drainage of lymphatic fluid from the right side of the body, which includes the face, the neck, and the mouth. These lymph nodes are a part of the lymphatic system, a network of tissues and organs that aids in the body's natural process of filtering out waste materials, poisons, and other potentially hazardous substances.
Left Submandibular Lymph nodes
The left submandibular lymph nodes are positioned slightly below the left side of the mandible (jawbone), in close proximity to the angle of the jaw. They are critical for draining lymphatic fluid from the left side of the face, neck, and mouth. The immune system relies on lymph nodes to help the body fight off illness and infection. Left submandibular lymph node enlargement or pain may indicate an infection or other medical problem.
Submandibular Lymph nodes Function
The submandibular lymph nodes are located in the region that separates the submandibular salivary glands. These glands are located underneath the tongue, and the mandible, also known as the lower jawbone. Sometimes one or more of the lymph nodes might be found deep in the salivary gland. This can happen on rare occasions.
These lymph nodes are an integral component of the immune system, which works to protect the body from infectious illnesses and other pathogens. They serve as sites of cellular filtration and proliferation. They cleanse the lymph system of undesirable waste and pathogens and function as early detection mechanisms for disease.
Submandibular Lymph nodes Swelling
The malignant condition may damage the submandibular gland, despite the fact that it accounts for less than 2% of head and neck malignancies. Nearly fifty percent of submandibular gland tumors are malignant. The most often observed submandibular gland malignancies are adenoid cystic and mucoepidermoid carcinomas. It might be challenging to diagnose tumors since they typically present as an asymptomatic growth in the inferior mandible or floor of the mouth. Assessment often comprises cross-sectional imaging and fine needle aspiration biopsy guided by ultrasonography.
Submandibular Lymph nodes Pain
The excessive generation of white blood cells can provide the appearance of painful and enlarged lymph nodes. This is caused by an infection (or lymphocytes ). This is a countermeasure for defending the body against invading particles. As a result, an increase in the white blood cell count might result in severe swelling and discomfort of the lymph nodes. Infections are the most prevalent cause of lymph node pain, while inflammation and swelling due to an injury elsewhere may also be a reason.
Submandibular Lymph nodes Treatment
The first course of treatment is conservative and consists of sialagogues and oral hydration. Surgery is only advised when all other treatments have failed and symptoms are still present. Excision of the submandibular gland may be a part of the treatment plan for benign tumors and some low-grade cancers. For aggressive pathological changes or advanced tumor stages, treatment options include selective neck dissection and adjuvant radiotherapy. Chemotherapy is a less popular treatment option for salivary cancers.
