The Anatomy of the Submandibular Glands
To understand why the submandibular glands can appear to 'drop', it is essential to first understand their normal anatomy. The submandibular glands are one of the three major pairs of salivary glands in the human body, situated beneath the floor of the mouth and on either side of the jawline. They are housed within the submandibular triangle, a complex region of the neck bordered by the mandible and the digastric muscles. Their function is to produce saliva, which aids in digestion and protects oral tissues. The glands are surrounded by muscles, fat, and fascia that hold them in place. The superficial layer of the neck, known as the platysma muscle, provides additional support and shape to the area.
How the Aging Process Affects Neck Tissues
Natural aging profoundly impacts the structures surrounding the submandibular glands, making them more noticeable. Several key processes are at play:
- Loss of Skin Elasticity: The production of collagen and elastin, the proteins responsible for skin's firmness, declines with age. The skin on the neck is particularly thin, and this loss of elasticity causes it to sag and wrinkle more visibly.
- Weakening Platysma Muscle: The platysma muscle, a sheet-like muscle covering the front of the neck, weakens over time. It can separate in the middle, creating prominent vertical bands often referred to as a "turkey neck". This loss of muscular tension contributes to the descent of the overlying tissues.
- Fat Redistribution and Loss: As we age, fat can be lost from certain areas of the face and neck, while accumulating in others. The fat pads that once concealed the submandibular glands can diminish, effectively unmasking the glands beneath. Conversely, a redistribution of fat can also contribute to a less defined jawline.
The Resulting Phenomenon: Submandibular Gland Ptosis
When people ask, "do submandibular glands drop with age?", they are often observing a condition known as ptosis, or drooping, of these glands. This is not a failure of the gland itself, but rather a consequence of the changes in the surrounding support structures. As the platysma muscle and other fascia weaken, the glands, which are under the pull of gravity, can shift downwards and become more prominent. This change becomes even more apparent after cosmetic procedures like facelifts or neck lifts, where excess fat and skin are removed, revealing the sagging glands that were previously hidden.
Ptosis vs. Swelling: Telling the Difference
It is crucial to distinguish between age-related ptosis, which is primarily a cosmetic issue, and gland swelling, which can indicate an underlying medical problem. Here's a quick comparison:
| Feature | Submandibular Gland Ptosis (Drooping) | Submandibular Gland Swelling (Sialadenitis) |
|---|---|---|
| Appearance | Soft, bilateral fullness under the jawline that is usually symmetrical. Becomes more noticeable after neck contouring surgery. | Often a hard, painful lump that can appear suddenly. Can be unilateral or bilateral. |
| Sensation | Painless, with no change in function. | Can cause tenderness, pain (especially with eating), fever, and chills. |
| Duration | Develops gradually over many years as part of the natural aging process. | Can be acute, resolving over days or weeks, or chronic with recurring episodes. |
| Cause | Loss of tissue elasticity and muscle tone in the neck, gravity, and fat redistribution. | Obstruction (salivary stones), infection (bacterial or viral), autoimmune diseases, or inflammation. |
| Associated Symptoms | Typically none, other than aesthetic changes. | May include a bad taste in the mouth, reduced saliva flow, or difficulty swallowing. |
If you experience any pain, sudden swelling, or other symptoms associated with gland swelling, it is important to consult a healthcare professional.
Factors that Contribute to and Exacerbate Gland Prominence
While aging is the primary driver of submandibular gland ptosis, several factors can accelerate or worsen the appearance of drooping glands:
- Genetics: Your genetic predisposition for skin elasticity and facial structure plays a significant role in how and when your neck ages.
- Significant Weight Fluctuations: Rapid weight loss or gain can impact the fat pads around the neck, influencing the visibility of the glands.
- Prior Neck or Facelift Surgery: As mentioned, removing fat and tightening superficial tissues can reveal prominent glands that were previously well-concealed.
- Environmental Factors: Sun exposure and other environmental stressors can accelerate the loss of collagen and elastin, contributing to earlier sagging.
Addressing the Aesthetic Concerns
For those bothered by the appearance of drooping submandibular glands, various cosmetic and surgical options exist. Surgical intervention is often the most effective approach for significant ptosis. Procedures can include:
- Submandibular Gland Reduction or Resection: In this procedure, the gland is either partially or fully removed, offering a long-term solution for a more defined jawline. Risks, such as nerve injury or salivary gland issues, must be carefully considered and discussed with a surgeon.
- Basket Submandibular Gland Suspension: A newer technique, this involves using sutures to lift and support the gland, restoring it to a more youthful position with minimal complications.
- Botulinum Toxin Injections: In some cases, botulinum toxin can be injected to reduce the size of the gland, helping to soften the appearance of fullness.
However, it's important to remember that these procedures, especially surgical ones, carry risks and should be thoroughly discussed with a qualified medical professional. For those seeking non-invasive options, lifestyle changes such as weight management and diligent sun protection can help manage skin laxity.

Conclusion
To definitively answer the question, "do submandibular glands drop with age?", the process is more nuanced than a simple drop. The glands don't simply detach and fall. Instead, the loss of skin elasticity, weakening neck muscles, and fat redistribution create an environment where the glands become more visible and appear to droop, a phenomenon known as ptosis. Distinguishing this natural aging effect from pathological swelling is crucial, and any pain or sudden swelling warrants a medical evaluation. For cosmetic concerns, a range of options, from non-invasive approaches to surgical intervention, can be considered after careful consultation with a specialist.
