Why Discuss the Submandibular Glands?
A deep neck lift is a transformative procedure that enhances the contours of the neck and jawline. However, patients often ask whether addressing the submandibular glands—a crucial part of the salivary gland system—impacts saliva production or digestion. This blog clarifies their role, why we sometimes refine them during surgery, and whether this affects oral function.
Understanding the Submandibular Glands and Their Role
The submandibular glands are part of the body's salivary gland network, which includes the parotid glands (near the cheeks), sublingual glands (under the tongue), and minor salivary glands distributed throughout the mouth. These glands work together to produce saliva, which aids in:
- Digesting food by breaking down starches
- Maintaining oral health by washing away bacteria and debris
- Lubricating the mouth and throat for comfort
The submandibular glands contribute 60–70% of total saliva production, but they do not work alone—other salivary glands compensate when needed.
Why Do We Address the Submandibular Glands in a Deep Neck Lift?
Not every deep neck lift patient requires submandibular gland contouring. However, for some individuals with prominent, bulky, or low-positioned glands, they can contribute to:
- A full, heavy appearance under the chin
- A lack of definition in the jawline
- Persistent fullness despite skin tightening
Simply tightening the skin or removing fat won’t correct glandular fullness, making selective gland contouring an important step for achieving sharp, refined contours.
Does Removing or Contouring the Submandibular Glands Affect Saliva Production?
This is one of the most common concerns—and the short answer is no, it does not significantly impact saliva production or digestion. Here's why:
Partial Refinement, Not Full Removal
- We do not remove the entire submandibular gland. Instead, we precisely contour the bulk or reposition it, preserving function.
Redundancy in Salivary Function
- The parotid glands (which contribute a large portion of saliva) remain fully functional.
- The sublingual and minor salivary glands continue to produce adequate saliva.
Clinical Studies & Surgeon Experience Show No Issues
- Research and real-world cases indicate no meaningful long-term changes in dry mouth symptoms after submandibular gland contouring.
- This means patients continue to have normal saliva production, ensuring no disruption in digestion, speech, or oral health.
Who Is a Good Candidate for Submandibular Gland Contouring?
This is not a one-size-fits-all approach. Ideal candidates include those who:
- Have visible gland fullness contributing to a heavy neck
- Desire a sharper jawline beyond what fat removal and muscle tightening can achieve
- Have good overall salivary function with no history of chronic dry mouth or gland dysfunction
A detailed consultation and physical exam determine whether gland refinement is needed.
What About Other Procedures That Can Affect the Salivary Glands?
Some patients may also wonder how submandibular gland contouring compares to other procedures that involve the salivary system, such as:
- Parotidectomy (removal of the parotid gland): This is performed for medical conditions like tumors, but it does not apply to cosmetic neck lifts.
- Sialendoscopy (salivary gland stone removal): This is a treatment for gland blockages and does not impact aesthetic procedures.
A deep neck lift with selective gland contouring is performed for aesthetic reasons only and is distinct from medical interventions.
Postoperative Expectations: Will I Feel Any Different?
After surgery, patients might briefly notice:
- Mild swelling or tightness under the chin
- A temporary sensation of fullness or stiffness in the neck
- No significant dry mouth or change in saliva flow
These effects resolve within weeks to months, with normal function intact.
Final Thoughts: Enhancing Aesthetics While Preserving Function
Submandibular gland contouring is a safe, well-researched technique that refines the jawline without disrupting salivary function. When performed selectively, it enhances results for the right candidate while maintaining a natural, well-balanced postoperative experience.
At our Miami-based practice, we specialize in tailored deep neck lifts, ensuring that each patient receives a customized approach that maximizes beauty while preserving function.
