Submandibular gland excision is a surgery to remove one of the saliva glands located under the lower jaw. It is usually advised when the gland has repeated infection, stones, persistent swelling or a suspected tumour.

Submandibular gland excision may sound complex, but it is a well-established ENT and head and neck procedure when performed by experienced surgeons. This article explains why the surgery is done, how the procedure works, what risks to understand and what recovery usually looks like.

Before deciding on submandibular gland excision, an ENT specialist will assess your symptoms, scan results and overall health. The goal is always to treat the problem safely while preserving speech, swallowing, facial movement and quality of life.

What Does the Submandibular Gland Do?

The submandibular glands are a pair of salivary glands found beneath the lower jaw, one on each side. They produce saliva that helps with chewing, swallowing and keeping the mouth moist. Saliva from this gland drains into the mouth through a tube called Wharton’s duct.

Problems develop when saliva flow is blocked or the gland becomes inflamed. A stone, infection, scarring or abnormal growth can make the gland painful and swollen, especially during meals. In some patients, these symptoms keep coming back despite medicines and conservative treatment.

When Is Submandibular Gland Excision Recommended?

Doctors usually consider submandibular gland excision when the gland is no longer functioning properly or when there is concern about a lump. It is not the first step for every patient with salivary gland swelling. The decision depends on the cause, severity and recurrence of symptoms.

Common reasons include recurrent sialadenitis, which means repeated infection or inflammation of the salivary gland. Another frequent cause is a salivary stone that blocks the duct and causes swelling during eating. In some cases, the surgery is done to remove a benign or suspicious tumour for diagnosis and treatment.

Submandibular gland excision is more likely to be recommended when:

• Painful swelling keeps returning despite antibiotics or other treatment

• A large or deep stone cannot be removed through the mouth or by endoscopy

• Imaging shows a mass that needs removal and laboratory testing

• Chronic infection has damaged the gland

• Symptoms interfere with eating, speaking or daily comfort

If your doctor suspects a stone-related obstruction, less invasive options may be discussed first. You can also read more about What Is Sialendoscopy?, a technique used in selected cases to diagnose and treat salivary duct stones.

How Doctors Diagnose the Problem Before Surgery

Before submandibular gland excision, the ENT specialist will take a detailed history and examine the mouth, floor of mouth and neck. They may ask whether swelling increases during meals, whether there is pus in the mouth or whether there is numbness, weight loss or persistent pain.

Tests are selected based on the suspected cause. Ultrasound is commonly used to check for stones, swelling and masses. CT or MRI may be needed for deeper stones or tumours. Fine needle aspiration cytology may be advised if there is a lump that needs cell testing before surgery.

Preparing for Submandibular Gland Excision

Preparing for submandibular gland excision begins with a clear discussion with your surgeon. You should understand why surgery is advised, what alternative options exist and what result is expected. Share details about diabetes, blood pressure, bleeding disorders, allergies and medicines such as blood thinners.

Your doctor may ask for blood tests, imaging reports and anaesthesia fitness before the operation. Most patients are advised not to eat or drink for a set number of hours before general anaesthesia. If infection is present, antibiotics may be given before surgery to reduce inflammation.

What Happens During the Procedure?

During submandibular gland excision, the patient is usually given general anaesthesia. The surgeon makes a small incision in the upper neck below the jawline, then carefully identifies and removes the affected gland. The surgical approach is planned to protect nearby nerves, blood vessels and surrounding tissues.

Important nerves near the gland include the marginal mandibular branch of the facial nerve, which helps move the lower lip. The lingual nerve is involved in tongue sensation and taste while the hypoglossal nerve helps tongue movement. Skilled dissection is essential because these structures are close to the gland.

After the gland is removed, bleeding is controlled and the wound is closed with sutures. A small drain may be placed for a short time to prevent fluid collection. The removed gland is usually sent for histopathology, which means laboratory examination under a microscope.

Recovery After Surgery

Recovery after submandibular gland excision varies from person to person, but many patients can return home the same day or after short observation depending on the hospital protocol and medical condition. Mild pain, tightness, swelling and bruising around the incision are common in the first few days.

Your doctor may prescribe pain relief, antibiotics if needed and wound care instructions. Soft foods may feel more comfortable initially. Most patients are advised to avoid heavy lifting, strenuous exercise and rubbing the incision until healing is satisfactory.

Stitches may dissolve on their own or be removed at a follow-up visit. The scar usually fades with time, although the final appearance depends on skin type, wound healing and sun exposure. Any fever, increasing redness, worsening swelling, pus discharge, breathing difficulty or sudden neck swelling should be reported urgently.

Possible Risks and Complications

The main risks of submandibular gland excision are similar to other surgeries, including bleeding, infection, pain and scar formation. Specific risks are related to the nearby nerves and salivary structures.

Temporary lower lip weakness may occur if the marginal mandibular nerve is stretched or irritated. Tongue numbness or altered taste can happen if the lingual nerve is affected. Injury to the hypoglossal nerve is rare, but it can cause tongue movement difficulty. Other possible issues include saliva leakage, fluid collection, wound numbness and persistent discomfort.

These complications are not common in every patient, but they should be discussed before surgery. Choosing an experienced ENT and head and neck surgeon helps reduce risk and supports early management if any issue develops.

Are There Alternatives to Surgery?

Submandibular gland excision is not always the first option. If the problem is a small stone near the duct opening, the doctor may remove it through the mouth. Sialendoscopy may help in selected cases, especially when the duct can be accessed and the stone size is suitable.

For infection, antibiotics, hydration, warm compresses, gland massage and sour candies to stimulate saliva may be used. These treatments are useful when the gland can recover. However, when attacks keep returning or a tumour is suspected, surgery may become the safest long-term option.

Why Choosing the Right ENT Team Matters

Because submandibular gland excision is performed close to important nerves, experience and technology matter. A good ENT team will not only perform the surgery, but also confirm whether surgery is truly needed. This is especially important for patients with repeated swelling, stone disease or a neck lump that needs careful evaluation.

If you are looking for an ENT clinic in Kerala or the best ENT surgeon in Kerala, consider whether the hospital offers diagnostic imaging, head and neck expertise, emergency ENT support and structured follow-up.

Conclusion

Submandibular gland excision can solve repeated infections, painful salivary stones and gland lumps when conservative treatment is not enough. The procedure involves careful removal of the gland under anaesthesia, with attention to nearby nerves and long-term function.

The key message is simple: not every submandibular gland problem needs surgery, but persistent swelling, meal-time pain or a suspicious lump should not be ignored. Early assessment helps your ENT specialist decide whether medicines, sialendoscopy or surgery is the right path.

Frequently Asked Questions

Is submandibular gland excision painful? 

The procedure is done under anaesthesia, so you should not feel pain during surgery. Mild to moderate pain after surgery is common and is usually controlled with prescribed medicines.

Will removing one submandibular gland cause dry mouth? 

Most patients do not develop severe dry mouth because other salivary glands continue to produce saliva. Some temporary dryness may occur, but long-term dryness is uncommon after removal of one gland.

How long does it take to recover?

 Many patients resume light daily activities within one to two weeks. Full healing of the incision and internal tissues takes longer, so follow your surgeon’s advice about exercise, diet and wound care.

Can salivary stones come back after gland removal?

 Once the affected gland is removed, stones cannot form in that gland again. However, other salivary glands can rarely develop stones, so new symptoms should be checked by an ENT specialist.

Is the scar visible? 

The incision is usually placed in a neck crease or under the jawline to make the scar less noticeable. Scar visibility depends on surgical technique, wound healing and individual skin response.
