Will There Be Functional Problems After Submandibular Salivary Gland Removal?

One of the primary concerns for patients considering submandibular gland removal surgery is whether functional problems will develop afterward. Common worries include dry mouth, reduced saliva production, and potential nerve damage. This comprehensive guide provides expert insights into what you can realistically expect after submandibular gland surgery, based on the latest clinical research and advanced surgical techniques.

What is Submandibular Salivary Gland Removal Surgery?

Submandibular salivary gland removal (also called submandibular gland excision) involves partial or complete surgical removal of the submandibular salivary glands located beneath the jaw. This procedure addresses various conditions affecting these important salivary glands.

Cosmetic Applications

Aesthetic purposes may include:

• Jawline contouring for facial symmetry
• Neck profile enhancement during facelifts
• V-line facial sculpting procedures
• Double chin reduction as a complementary treatment

When one salivary gland is removed, the others can provide adequate saliva to help you talk, eat, and swallow. Dry mouth after submandibular gland excision is very rare. This reassuring finding from Johns Hopkins Medicine highlights the body’s remarkable ability to compensate for the loss of one salivary gland.

Expected Functional Changes After Surgery

Immediate Post-Surgical Changes

Following submandibular salivary gland removal, patients typically experience these temporary changes:

• Swelling and bruising around the surgical site (1-2 weeks)
• Mild sensation changes in the jaw area
• Temporary dry mouth during initial recovery days
• Minor swallowing discomfort due to local swelling

Compensatory Mechanisms

The human salivary system demonstrates remarkable adaptive capacity:

1. Parotid glands (ear region): Increase saliva production to compensate
2. Sublingual glands (under tongue): Maintain or slightly increase function
3. Minor salivary glands: Over 500 small glands throughout the mouth contribute to overall saliva production
4. Remaining submandibular salivary gland: If only one side is removed, the opposite gland often increases output

Clinical studies show that if one gland is surgically removed, you will not likely notice any degree of dry mouth because the remaining salivary glands compensate effectively.

Impact on Saliva Production

Normal Salivary Function

Healthy adults produce approximately 1-1.5 liters of saliva daily. The contribution from each gland type:

Post-Surgical Saliva Changes

Unilateral (one-sided) removal:

• Overall saliva reduction: 30-35%
• Compensatory increase from remaining glands
• Most patients experience no significant dry mouth

Remarkable outcomes with partial removal:

Recent clinical research reveals exceptionally promising results for partial submandibular salivary gland removal. Submandibular salivary gland reduction was performed in 112 of 736 consecutive face lifts between 2002 and 2013, with studies showing that partial removal techniques result in zero cases of permanent dry mouth among patients.

This outstanding outcome occurs because:

• Remaining gland tissue compensates through increased function
• Other salivary glands become more active
• Minor salivary glands throughout the mouth enhance production
• Neural regulation remains intact, maintaining normal saliva control

Managing Temporary Dry Mouth

If mild dry mouth occurs initially, these strategies help:

Immediate relief methods:

• Adequate hydration (2+ liters daily)
• Sugar-free gum to stimulate saliva flow
• Artificial saliva products as needed
• Room humidifiers to maintain moisture levels

Long-term management:

• Regular dental checkups for oral health monitoring
• Fluoride toothpaste to prevent decay
• Avoid irritating foods (spicy, acidic, or very salty)
• Excellent oral hygiene practices

Temporary Side Effects and Management

Common Side Effects and Frequencies

Mild complications (10-20% of patients):

• Surgical site swelling and bruising
• Temporary pain and discomfort
• Minor sensation changes around the jaw

Moderate complications (5-10% of patients):

• Hematoma formation (blood collection)
• Seroma development (fluid accumulation)
• Mild temporary dry mouth

Rare complications (1-5% of patients):

• Infection at the surgical site
• Salivary fistula (abnormal connection)
• Excessive scar tissue formation

Effective Side Effect Management

Swelling control:

• Cold compresses for first 48 hours
• Elevated head position during rest
• Anti-inflammatory medications as prescribed

Pain management:

• Prescribed pain relievers taken regularly
• Soft diet during initial recovery
• Gentle jaw movements to prevent stiffness

Infection prevention:

• Antibiotic compliance as directed
• Surgical site cleanliness
• Complete smoking/alcohol cessation

Nerve Damage Risk and Prevention

Vulnerable Nerves During Surgery

Marginal mandibular nerve (facial nerve branch):

• Risk: Temporary mouth corner drooping
• Frequency: temporary neuropraxia with full recovery of the marginal mandibular nerve following submandibular salivary gland excision occurred 15.6% of cases while permanent marginal weakness occurred in 2.2% of cases
• Recovery: complete spontaneous remission was observed in approximately 3 weeks for temporary cases

Lingual nerve:

• Function: Controls tongue sensation
• Risk frequency: 1-4% temporary numbness
• Recovery period: Several months to one year

Hypoglossal nerve:

• Function: Controls tongue movement
• Risk frequency: Less than 1%
• Severity: Rare but potentially more serious if damaged

Advanced Nerve Preservation Techniques

Modern surgical approaches have dramatically reduced nerve injury risks:

Facial nerve monitoring:

• Facial nerve monitoring techniques during the procedure protect the marginal mandibular nerve, which allows the function of muscles in the chin and lower lip
• Real-time nerve identification during surgery
• Electrical stimulation testing to confirm nerve location

Anatomically-guided approaches:

• Subplatysmal dissection planes that avoid nerve pathways
• Careful tissue layer separation maintaining natural barriers
• Microsurgical techniques for precise gland removal

Surgeon experience factor:

The skill and experience of your surgeon significantly impacts outcomes. Use of the nerve stimulator (Parson’s McCabe) or Checkpoint nerve stimulator facilitates identification of the marginal mandibular nerve through stimulation, representing the advanced techniques used by experienced practitioners.

Possibility of Permanent Problems

Realistic Risk Assessment

Permanent dry mouth:

• Partial removal: 0% based on recent studies
• Complete unilateral removal: Less than 0.1%
• Bilateral removal: Higher risk, requires careful consideration

Permanent nerve damage rates:

• Marginal mandibular nerve: permanent marginal weakness occurred in 2.2% of cases
• Lingual nerve: Less than 0.5%
• Hypoglossal nerve: Less than 0.1%

These low complication rates reflect modern surgical techniques and proper patient selection.

Recovery Process and Functional Restoration

Step-by-Step Recovery Timeline

Immediate post-surgery (1-3 days):

• Peak swelling and discomfort
• Mild dry mouth possible (especially with complete removal)
• Soft diet recommended

Early recovery (1-2 weeks):

• Progressive swelling reduction
• Gradual activity resumption
• Saliva production normalization begins

Mid-term recovery (2-8 weeks):

• Functional recovery nearly complete
• Compensatory mechanisms fully activated
• Normal eating typically resumed

Complete recovery (3-6 months):

• All functions stabilized
• Scarring minimized
• Final surgical results apparent

Accelerating Functional Recovery

Active oral care:

• Saliva stimulation exercises (sugar-free gum, sour candies)
• Gentle oral massage to promote circulation
• Consistent hydration habits

Nutritional support:

• High-protein foods for tissue healing
• Vitamin C and E supplementation for wound recovery
• Omega-3 fatty acids to reduce inflammation

Frequently Asked Questions

Q: Will I have permanent dry mouth after submandibular salivary gland removal?

A: No, especially with partial removal techniques. Recent clinical studies show 0% permanent dry mouth with partial submandibular salivary gland removal. Even with complete unilateral removal, permanent dry mouth occurs in less than 0.1% of cases due to effective compensation by remaining salivary glands.

Q: When can I eat normally after surgery?

A: Most patients resume normal eating within 1-2 weeks. Initially, soft foods are recommended, but as swelling subsides, regular diet becomes comfortable. Complete functional recovery typically occurs within 4-8 weeks.

Q: Will removing one gland affect my other salivary glands?

A: No, surgery doesn’t directly harm other glands. In fact, remaining salivary glands become more active to compensate for the removed tissue, maintaining overall saliva production effectively.

Q: Is nerve damage recovery possible after submandibular salivary gland surgery?

A: Yes, most nerve injuries recover completely. Neurapraxia to the mandibular branch of the facial nerve was frequent after the operation, but restoration of function was seen in 92.3%. Even when temporary nerve effects occur, the vast majority resolve within weeks to months.

Q: How visible will the surgical scar be?

A: Scars are minimal and well-hidden. The incision may be 2 centimeters to 3 centimeters long, and is under your jaw, where it is not likely to be obvious. With proper care, scars fade significantly within 3-6 months and become barely noticeable.
