Submandibular Gland Excision for Refined Neck Contour and Jawline Definition

Dr. Philip Miller

February 12, 2026

Persistent fullness beneath the jawline can soften the neck and cover definition, even in patients who maintain a healthy weight or have already pursued aesthetic treatments. For many individuals, this concern is not solely about excess fat or loose skin. Instead, it is often associated with enlarged submandibular glands, which sit just below the jaw.

Fortunately, submandibular gland excision offers a precise surgical solution for patients seeking sharper definition and more refined neck contours. Under the expert care of Philip J Miller, MD, FACS, this advanced approach plays an important role in comprehensive neck contouring surgery. 

Today, we will explore why gland-related fullness occurs, when submandibular gland removal is appropriate, and how it enhances modern neck rejuvenation surgery.

Why Fullness Under the Jawline Persists Despite a Healthy Lifestyle

Many patients assume fullness beneath the jawline is caused by weight gain or aging skin. However, the anatomy of the neck is complex, and multiple structures influence its appearance.

In some cases, the issue stems from:

• Enlarged submandibular glands
• Natural changes in tissue support with age
• Genetics that influence gland prominence

As a result, even patients with excellent skin tone may notice a rounded or bulky appearance under the jaw. This is precisely where traditional fat reduction techniques may fall short, making surgical evaluation essential.

The Submandibular Glands and Their Impact on Neck Appearance

The submandibular glands are salivary glands located beneath the jawbone on each side of the neck. While their function is essential, their size and position can influence external contour.

Over time, these glands may become more visible due to age-related tissue changes or natural anatomy. When this occurs, the jawline loses definition, and the neck appears heavier, particularly in profile views. Submandibular gland removal addresses the underlying cause rather than masking it, allowing for a smoother, more sculpted neck contour.

When Submandibular Gland Excision Becomes Part of the Plan

Submandibular gland excision is not recommended for every patient. Instead, it is carefully considered when gland prominence clearly contributes to neck fullness.

This procedure may be appropriate when

• Fullness persists after weight stabilization
• Liposuction alone would not improve contour
• A patient desires sharper jawline definition

Through a detailed consultation, Dr. Miller evaluates anatomy, skin quality, and overall balance before recommending submandibular gland excision as part of a customized surgical approach.

How Submandibular Gland Removal Elevates Neck Contouring Surgery

Neck contouring surgery aims to restore clean lines and natural definition. When enlarged glands are left untreated, even well-performed procedures may appear incomplete.

By incorporating submandibular gland removal, the neck gains

• Improved jawline clarity
• A smoother transition from chin to neck
• Enhanced profile balance

As a result, the neck appears slimmer, more youthful, and better aligned with the lower face. This strategic refinement allows neck rejuvenation surgery to reach its full potential.

Combining Submandibular Gland Excision with Neck Lift Surgery and Micro Lift Techniques

For many patients, optimal results come from combining procedures rather than relying on a single solution. Submandibular gland excision is often performed alongside neck lift surgery or a micro lift to address multiple aging concerns simultaneously.

Common combinations include

• Neck lift surgery to tighten loose skin
• Micro lift techniques for subtle lower face support
• Conservative fat removal when appropriate

When thoughtfully combined, these techniques enhance contour while preserving a natural appearance.

Key Benefits of Submandibular Gland Excision

Patients considering this advanced procedure often appreciate its targeted impact on neck definition.

Benefits include:

• Reduced fullness beneath the jaw
• More defined jawline and neck angle
• Enhanced results from neck contouring surgery
• Natural-looking refinement without exaggerated changes

By addressing the structural cause of fullness, results appear balanced and proportionate.

Recovery and Healing After Submandibular Gland Removal

Recovery following submandibular gland excision is gradual and progressive. Initially, patients may experience swelling and firmness, which steadily improve over time.

Most individuals notice continued refinement over several weeks as tissues settle and contours sharpen. When performed as part of neck rejuvenation surgery, healing timelines are coordinated to ensure a smooth, comfortable recovery. Clear postoperative guidance ensures patients know what to expect at each stage.

Why Surgical Expertise Matters in Advanced Neck Rejuvenation Surgery

Submandibular gland excision requires an advanced understanding of facial and neck anatomy. Precision is essential to avoid overcorrection and to maintain natural contours.

Dr. Miller’s experience in facial plastic surgery allows for:

• Conservative gland reduction
• Meticulous attention to symmetry
• Results that complement the patient’s natural structure

This level of expertise is critical for performing complex neck rejuvenation surgery, which demands both technical skill and aesthetic judgment.

Precision That Redefines the Neck and Jawline

Submandibular gland excision offers a powerful solution for patients frustrated by persistent fullness under the jawline. When thoughtfully integrated into neck lift surgery or comprehensive neck contouring surgery, it delivers refined definition and lasting improvement.

Refined contours begin with expert precision.
