Located beneath the lower jaw, the submandibular glands are one of the three primary salivary glands responsible for producing saliva, which plays a crucial role in digestion, lubrication, and maintaining oral health. Tumors arising from these glands, known as submandibular tumors, can be benign (non-cancerous) or malignant (cancerous). Their development and growth can lead to a range of symptoms and may require various treatments.

Types of Submandibular Tumors

Submandibular tumors can be of various types, with each having distinct characteristics. Some of the common types include:

  • Pleomorphic Adenomas: These benign tumors are the most frequently observed among submandibular tumors. Although non-cancerous, they can grow and push against nearby structures or transform into malignant tumors if left untreated.
  • Adenoid Cystic Carcinomas: This is a type of malignant tumor that grows slowly but can spread to nearby nerves and other structures.
  • Mucoepidermoid Carcinomas: Another form of malignant tumors, these can vary in their aggressiveness.

Symptoms

Tumors in the submandibular gland might initially appear as a painless lump beneath the jaw. As they grow, they can lead to various symptoms, such as:

  • Pain or discomfort in the area, especially if the tumor pushes against nerves or other structures.
  • Facial numbness or weakness if the tumor affects the facial nerves.
  • Difficulty swallowing or a feeling of something being stuck.
  • Swelling or fluid accumulation in the neck or face.

Causes and Risk Factors

The precise causes of submandibular tumors remain somewhat elusive, but some factors may increase the risk of their development:

  • Radiation exposure: Previous radiation treatments to the head or neck can increase the risk of salivary gland tumors.
  • Genetics: Some inherited genetic mutations or conditions can make individuals more susceptible.
  • Age: The risk of developing salivary gland tumors increases with age.
  • Exposure to certain substances: People exposed to specific workplace substances, such as certain metals or minerals, might have a higher risk.

Diagnosis and Treatment

Accurate diagnosis is vital for effective treatment. The diagnostic process typically involves:

  • Physical examination: Checking for lumps or abnormalities in and around the submandibular area.
  • Imaging tests: MRI or CT scans can provide detailed images of the gland and surrounding structures, helping determine the tumor’s size and location.
  • Biopsy: A sample of tissue is removed from the lump and analyzed to determine if the tumor is benign or malignant.

Depending on the type, size, and location of the tumor, treatment options might include:

  • Surgery: This is the most common treatment for submandibular tumors. The procedure aims to remove the tumor, and in some cases, the entire submandibular gland might be removed to ensure complete removal.
  • Radiation therapy: This is commonly used for malignant tumors, especially if there’s a concern about cancerous cells remaining post-surgery or if surgery isn’t an option.
  • Chemotherapy: While not a standard treatment for submandibular gland tumors, chemotherapy might be considered if the cancer has spread to other parts of the body.

Advances in surgical techniques and therapies ensure effective treatment, leading to positive outcomes for most individuals. While benign tumors are usually non-life-threatening, their potential to transform or cause discomfort underscores the importance of addressing any submandibular growth or anomaly promptly. Proper care, regular follow-ups, and early detection can mitigate potential complications and ensure optimal oral and overall health.
