Not every salivary gland problem requires surgery. Some conditions improve with hydration, medication, treatment of infection, or minimally invasive procedures. However, when a salivary gland develops a persistent blockage, recurrent infection, a troublesome growth, or a tumor that needs to be removed, surgery may become an important part of treatment.
The decision depends on what is affecting the gland, how severe or persistent the symptoms are, whether the problem can be treated without removing the gland, and whether there is any concern about cancer. If you are exploring your treatment options, our Salivary Gland Surgery page provides an overview of the conditions treated and the surgical approaches that may be used.
What Problems Can Lead to Salivary Gland Surgery?
Salivary gland surgery may be considered for several different conditions. The three major pairs of salivary glands are the parotid glands near the ears, the submandibular glands beneath the jaw, and the sublingual glands beneath the tongue. Problems can also develop in the smaller minor salivary glands found throughout the mouth and throat.

Common reasons for considering surgery include:
- Salivary gland tumors or other growths
- Repeated salivary gland infections
- Salivary gland stones that cannot be removed by less-invasive methods
- Persistent blockage or narrowing of a salivary duct
- Chronic inflammation or damage to a gland
- Recurrent swelling and pain that significantly affects daily life
- Some cysts or other structural abnormalities
The appropriate treatment is different for each condition. In many cases, the goal is to treat the underlying problem while preserving as much healthy gland tissue and function as possible.
1. A Salivary Gland Tumor May Need to Be Removed
A lump in a salivary gland does not automatically mean cancer. In fact, many salivary gland tumors are benign. However, a persistent or suspicious mass usually needs proper evaluation because both benign and malignant tumors can occur in the salivary glands.
Surgery may be recommended when a tumor needs to be removed for treatment or when its nature cannot be established reliably without removing tissue. The type and extent of surgery depend on the gland involved, the size and location of the tumor, its characteristics on imaging and biopsy, and whether cancer is suspected or confirmed.
For salivary gland cancer, surgery is commonly an important part of treatment. Depending on the disease, the operation may involve removal of part or all of the affected gland and, in selected cases, nearby lymph nodes. Additional treatment such as radiation therapy may be considered based on the tumor's characteristics and the findings after surgery.
2. Recurrent Salivary Gland Stones May Require Surgery
Salivary gland stones, also called sialoliths, can block the flow of saliva through a gland or its duct. This may cause swelling and pain, particularly around mealtimes, and a blocked gland can sometimes become infected.
Small stones may sometimes pass naturally or can be managed with measures that encourage saliva flow. When a stone remains stuck, however, it may need to be removed.
Importantly, stone removal does not always mean removing the entire gland. Depending on the size and location of the stone, a specialist may be able to remove it through the duct using sialendoscopy, a minimally invasive technique that uses a small endoscope to examine the salivary duct and, in appropriate cases, remove the obstruction.

For larger or deeply positioned stones, a combined endoscopic and surgical approach may sometimes be used. Removal of the entire affected gland may be considered when the gland has significant damage, symptoms continue despite less-invasive treatment, or the obstruction cannot be adequately treated by other methods.
3. Repeated Infections Can Be a Reason for Gland Removal
A salivary gland infection, known as sialadenitis, does not usually mean that surgery is immediately necessary. Treatment may initially focus on addressing the infection and improving saliva flow, depending on its cause.
However, repeated infections can sometimes occur when a gland or its duct remains chronically blocked or damaged. If infections keep returning despite appropriate treatment, surgery may be considered to remove the underlying source of the problem.

This is particularly relevant when recurrent infection is associated with a persistent stone or obstruction that cannot be effectively managed through less-invasive treatment.
4. Persistent Duct Narrowing or Blockage May Need an Operation
Salivary ducts can become narrowed, a condition sometimes referred to as a duct stricture. When saliva cannot flow normally, it may lead to repeated swelling, discomfort, and inflammation.
Depending on the cause and location of the narrowing, treatment may include duct dilation, sialendoscopy, or other gland-preserving techniques. Surgery may be considered when these approaches cannot adequately restore drainage or when the gland has become severely affected.
This is one reason why identifying the exact cause of recurrent salivary gland swelling is important before deciding on gland removal.
5. Chronic Salivary Gland Problems May Eventually Require Surgery
Some people experience repeated episodes of swelling and pain over a long period. These symptoms may occur because of stones, duct narrowing, chronic inflammation, or other structural problems.
If the underlying problem cannot be corrected and the affected gland continues to cause significant symptoms, surgery may become an option. The decision is generally based on the frequency and severity of symptoms, the condition of the gland, previous treatments, and whether a gland-preserving procedure is feasible.
In other words, surgery is not usually considered simply because a salivary gland has been troublesome once. Persistent or recurrent disease that does not respond adequately to appropriate treatment is more likely to prompt consideration of an operation.
When Is Salivary Gland Surgery Not Immediately Necessary?
Surgery is only one part of salivary gland treatment. Depending on the diagnosis, doctors may first recommend observation, medication, treatment of infection, hydration and measures to improve saliva flow, or a minimally invasive procedure.
For example, some salivary gland stones can pass naturally, while selected duct stones can be removed through sialendoscopy without removing the gland. Similarly, an infection may initially be treated without surgery when there is no persistent obstruction or other indication for an operation.
The key question is therefore not simply whether a salivary gland is abnormal, but what is causing the problem and whether the gland can be treated effectively without removing it.
Does Salivary Gland Surgery Always Mean Removing the Whole Gland?
No. The term “salivary gland surgery” covers several different procedures. Some operations remove only a stone or treat a blocked duct. Sialendoscopy may allow certain obstructions to be treated through the natural duct opening. In other situations, part or all of a gland may need to be removed.
For a parotid tumor, for example, the surgical approach depends on the tumor's location and characteristics. For a submandibular gland affected by recurrent obstruction or infection, complete gland removal may sometimes be recommended when other approaches are unsuitable.
The aim is to choose an operation that adequately treats the underlying condition while limiting unnecessary removal of healthy tissue.
What Are the Possible Benefits and Risks of Surgery?
The potential benefit of surgery depends on the reason for the operation. It may remove a tumor, eliminate a persistent obstruction, reduce recurrent infections, or relieve repeated swelling and pain.
Because important nerves and other structures lie close to the salivary glands, surgery can also carry specific risks. These vary according to the gland and type of procedure and may include bleeding, infection, scarring, changes in sensation, or temporary or permanent nerve-related problems.
For parotid surgery, particular attention is paid to the facial nerve because it passes through the gland. Other procedures may involve nerves associated with the tongue or lower lip. Your surgeon should explain the risks that specifically apply to the planned operation rather than assuming that every salivary gland procedure carries the same risks.

The Bottom Line
Salivary gland surgery may be needed when a tumor requires removal, a blockage or stone cannot be adequately treated with less-invasive methods, infections keep returning, or a gland has become persistently damaged and symptomatic. However, surgery is not automatically required for every salivary gland problem.
The most appropriate treatment depends on the underlying diagnosis, the gland involved, the severity and persistence of symptoms, and whether the gland can be safely preserved. A careful evaluation helps determine whether observation, medical treatment, minimally invasive treatment, or surgery is the most appropriate approach.
