Diagram of glands in neck. Comprehensive Guide to Neck Lymph Node Surgery: Types, Procedures, and Side Effects

What are lymph nodes and why are they important in cancer treatment. How does neck dissection surgery work and what are its different types. What are the potential side effects of neck lymph node removal and how can they be managed.

Understanding Lymph Nodes and Their Role in Cancer

Lymph nodes are small, bean-shaped glands distributed throughout the body, including the head and neck region. These structures play a crucial role in our immune system and are often the first site where cancer cells spread when they break away from a primary tumor. This characteristic makes lymph nodes a key focus in cancer treatment and staging.

In the context of salivary gland cancer, surgeons may recommend the removal of lymph nodes in the neck, a procedure known as neck dissection. However, this surgery is not routinely performed on all patients due to potential long-term side effects. Careful consideration is given to determine who will benefit most from this procedure.

When is Neck Dissection Recommended?

Neck dissection may be recommended in the following scenarios:

  • The salivary gland cancer is high grade
  • Lymph nodes are visibly swollen
  • Scans indicate the possibility of cancer cells in the lymph nodes

Types of Neck Dissection Procedures

There are three main types of neck dissection surgeries, each varying in the extent of tissue removal and potential impact on the patient’s anatomy and function.

Selective Neck Dissection

In a selective neck dissection, the surgeon removes lymph nodes from specific areas of the neck, typically those closest to the cancer site. This approach is less extensive than other types of neck dissection and aims to preserve as much healthy tissue as possible while addressing the cancer threat.

Modified Radical Neck Dissection

Modified radical neck dissection is a more comprehensive procedure with three subtypes. In its basic form, this surgery involves the removal of most lymph nodes between the jawbone and collarbone on one side of the neck. Depending on the extent of cancer spread, the surgeon may also need to remove one or more of the following structures:

  • The sternocleidomastoid muscle (a muscle on the side of the neck)
  • The accessory nerve (responsible for shoulder movement)
  • The internal jugular vein

This type of neck dissection is typically performed when cancer affects multiple lymph nodes in the neck.

Radical Neck Dissection

Radical neck dissection is the most extensive form of the surgery. It involves the removal of nearly all lymph nodes on one side of the neck, along with:

  • The sternocleidomastoid muscle
  • The accessory nerve
  • The internal jugular vein

This procedure is usually reserved for cases where cancer has spread to other nearby structures beyond the lymph nodes.

Potential Side Effects of Neck Dissection

The side effects of neck dissection can vary depending on the type of surgery performed and the structures affected or removed during the procedure. Understanding these potential complications is crucial for patients and healthcare providers alike.

Shoulder Stiffness and Arm Weakness

One of the most common side effects of neck dissection is shoulder stiffness and arm weakness. This occurs because the accessory nerve, which controls shoulder movement, may be affected during surgery. The severity and duration of this issue depend on the type of neck dissection performed:

  • In partial or modified neck dissection, weakness typically lasts for a few months
  • If the accessory nerve is removed, the damage may be permanent

To address this issue, patients are usually referred to a physiotherapist who can provide exercises to improve neck and shoulder movement. In some cases, where problems persist for a year after surgery, doctors may consider muscle reconstruction, although this option is not suitable for all patients.

Post-Operative Pain Management

Pain is a common side effect following neck dissection. How can patients manage post-operative pain effectively? Pain management typically involves a combination of approaches:

  • Use of appropriate painkillers
  • Engaging in prescribed physiotherapy exercises
  • Referral to a pain clinic for persistent or severe pain

Changes in Neck Appearance and Function

Neck dissection can result in changes to the appearance and function of the neck, particularly if the sternocleidomastoid muscle is removed. Patients may notice:

  • A thinner and shrunken appearance of the neck
  • Increased neck stiffness

Physiotherapy is often recommended to address neck stiffness and improve overall function.

Understanding and Managing Lymphoedema

Lymphoedema is a potential complication of neck dissection that requires careful attention and management. But what exactly is lymphoedema, and how does it manifest after neck surgery?

Lymphoedema refers to the buildup of lymph fluid that causes swelling. It can develop when surgery interferes with the normal flow of lymph in the lymphatic system. In the context of neck dissection, lymphoedema can affect not only the external neck area but also internal structures.

Symptoms of Lymphoedema

Patients should be aware of the following symptoms that may indicate lymphoedema:

  • Swelling or a feeling of fullness or pressure in the neck area
  • Difficulty swallowing
  • Changes in voice
  • Swelling of the tongue or other parts of the mouth

Early detection and treatment of lymphoedema are crucial to prevent the condition from worsening. Patients experiencing these symptoms should promptly inform their healthcare provider, who may refer them to a lymphoedema specialist for appropriate management.

Rare Complications: Chyle Leak and Haematoma

While less common, there are other potential complications that patients and healthcare providers should be aware of following neck dissection surgery.

Chyle Leak

A chyle leak is a rare but potentially serious complication that can occur after neck dissection. But what is chyle, and how does a leak occur?

Chyle is a type of lymph fluid that contains fat absorbed from the small intestine. It’s transported through lymphatic channels to the bloodstream. During neck dissection, the thoracic duct (a major lymphatic channel) may be damaged, leading to a leak. When this happens, chyle can collect under the skin, causing swelling and potentially interfering with healing.

Management of a chyle leak may require:

  • Extended hospital stay
  • Possible return to the operating room for surgical repair
  • Dietary modifications to reduce chyle production

Haematoma Formation

Another potential complication is the formation of a haematoma, or blood clot, under the skin. This can occur if the drainage tubes placed during surgery become blocked, preventing proper fluid evacuation. What are the signs of a haematoma, and how is it managed?

Signs of a haematoma may include:

  • Sudden swelling at the surgical site
  • Increased pain or pressure
  • Discoloration of the skin

If a haematoma forms, patients may need to return to the operating room for evacuation of the blood clot and to address the underlying cause.

Long-Term Follow-Up and Rehabilitation

Recovery from neck dissection surgery is a process that extends well beyond the immediate post-operative period. Long-term follow-up and rehabilitation are crucial components of the overall treatment plan.

Importance of Ongoing Physiotherapy

Physiotherapy plays a vital role in recovery from neck dissection. How can ongoing physiotherapy benefit patients?

  • Improves range of motion in the neck and shoulder
  • Helps manage and reduce pain
  • Addresses muscle weakness and imbalances
  • Facilitates return to normal daily activities

Patients are typically provided with a set of exercises to perform at home, in addition to regular sessions with a physiotherapist. Consistency and patience are key, as improvements may be gradual but significant over time.

Monitoring for Late-Onset Complications

While many side effects of neck dissection manifest shortly after surgery, some complications can develop or persist long-term. Regular follow-up appointments allow healthcare providers to monitor for and address issues such as:

  • Chronic pain
  • Persistent lymphoedema
  • Delayed onset of shoulder dysfunction
  • Neuroma formation (painful nerve growths)

Early detection and intervention for these issues can significantly improve outcomes and quality of life for patients.

Psychological Support and Quality of Life Considerations

The impact of neck dissection surgery extends beyond physical symptoms, often affecting patients’ emotional well-being and overall quality of life. Addressing these aspects is an integral part of comprehensive care.

Coping with Body Image Changes

Changes in neck appearance following surgery can be distressing for some patients. How can healthcare providers support patients in adapting to these changes?

  • Providing access to counseling services
  • Offering information on camouflage techniques and adaptive clothing
  • Connecting patients with support groups or peer mentors
  • Encouraging open communication about body image concerns

Addressing Functional Challenges

Functional changes, such as difficulty with shoulder movement or swallowing, can impact various aspects of a patient’s life. A multidisciplinary approach is often beneficial, involving:

  • Occupational therapy to assist with daily living activities
  • Speech and language therapy for swallowing and voice issues
  • Nutritional counseling to address dietary challenges
  • Vocational rehabilitation for those returning to work

By addressing both the physical and psychological aspects of recovery, healthcare providers can help patients achieve the best possible outcomes and maintain a good quality of life following neck dissection surgery.

Surgery to remove the lymph nodes in your neck | Salivary gland cancer

Lymph nodes are small bean shaped glands found throughout the body, including the head and neck area. They are often the first place cancer cells spread to when they break away from a tumour.

Surgery to remove the lymph nodes in the neck is called a neck dissection. Surgeons don’t routinely do a neck dissection on everyone because it can have long term side effects. They have to consider carefully who will benefit from it. 

You may have a neck dissection if your:

  • salivary gland cancer is high grade
  • lymph nodes are swollen
  • scans show that the lymph nodes might have cancer cells in them

There are different types of neck dissection:  

  • selective neck dissection
  • modified radical neck dissection
  • radical neck dissection

Partial or selective neck dissection

Your surgeon removes lymph nodes from some areas of your neck. It is usually the areas closest to the cancer. 

Modified radical neck dissection

There are 3 types of modified radical neck dissection.

With one type your surgeon removes most of the lymph nodes between your jawbone and collarbone on one side of your neck.

With the other 2 types your surgeon also needs to remove one or more of the following structures:

  • a muscle on the side of your neck called the sternocleidomastoid muscle
  • a nerve called the accessory nerve
  • a vein called the internal jugular vein

You might have a modified radical neck dissection if the cancer is affecting more than one of the lymph nodes on your neck.

Radical neck dissection

You have nearly all the nodes on one side of your neck removed. Your surgeon will also remove:

  • the sternocleidomastoid muscle
  • a nerve called the accessory nerve
  • the internal jugular vein

You might have a radical neck dissection if the cancer has spread to other nearby structures.

Side effects of neck dissection

The side effects depend on which structures have been removed or disturbed during surgery.

Shoulder stiffness and arm weakness

The accessory nerve controls shoulder movement. So if you have this removed, your shoulder will be stiffer and more difficult to move. If you have a partial or modified neck dissection, the weakness in your arm usually lasts only a few months. But if you have your accessory nerve removed, the damage is permanent.

Your doctor will refer you to a physiotherapist. They will show you some exercises to help improve the movement in your neck and shoulder. It is important that you do them.

Some people have problems with pain and movement a year after surgery. In this situation, your doctor may suggest a reconstruction of some of the muscles. But this isn’t suitable for everyone.

Pain

You may also have some pain. Taking painkillers can help. Physiotherapy exercises can also reduce pain. Your doctor can refer you to a pain clinic if the pain continues or is not controlled with painkillers.

A thinner, shrunken and stiff neck

Your neck will look thinner and shrunken if you have had the sternocleidomastoid muscle removed.

Your neck might be stiff after the operation and you might need physiotherapy.

Swelling (lymphoedema)

After surgery to remove some or all of the lymph nodes in your neck, the area can be swollen. This can be due to general swelling around the surgical wound. This usually goes down within a couple of weeks. But it can also be a sign of lymphoedema, this swelling doesn’t go away.

Lymphoedema means a build up of lymph fluid that causes swelling. It can develop because surgery interferes with the normal flow of lymph in the lymphatics.

Lymphoedema in the head or neck can also cause symptoms inside your mouth and throat. This may include swelling of your tongue and other parts of your mouth.

Tell your doctor or nurse straight away if you have:

  • any swelling or a feeling of fullness or pressure
  • find it difficult to swallow
  • have changes in your voice

They will refer you to a lymphoedema specialist if they think you might have lymphoedema. It’s important to start treatment early to stop the swelling from getting worse.

Chyle leak

Chyle is tissue fluid (lymph) that contains fat after it has been absorbed from the small bowel (intestine). It gets transported through the lymphatic channels to the bloodstream.

Sometimes one of these channels, called the thoracic duct, leaks after the operation. When this happens, lymph fluid or chyle can collect under the skin.

You may need to stay longer in hospital and go back to the operating theatre to repair the leak.

Blood clot

Sometimes the tubes of the drain that the surgeon puts in during surgery can become blocked. This can cause blood to collect under the skin and form a clot (haematoma). If this happens, you might need to go back to the operating theatre to have the clot removed and the drain replaced.

Other possible effects

You might have other effects due to damage to some of the nerves that supply the head and neck area.

They include:

  • numbness of the skin and the ear on the same side as the operation
  • loss of movement in the lower lip
  • loss of feeling or movement on one side of the tongue

Let your doctor or specialist nurse know about any side effects that you have so they can help you to cope with them.

Exercises for lymphoedema

Using your head, neck and shoulder muscles may help to reduce swelling. Your physiotherapist or specialist nurse will usually go through these exercises with you. 

These exercises shouldn’t be painful. You might have a feeling of stretching as you do them, this is normal. Stop doing the exercises if you have any pain and, if doesn’t get better contact your doctor.

Do the exercises slowly and gently, don’t rush them. You can rest between exercises. It might help to do them in front of the mirror so you can check that your shoulders are back and relaxed. 

Transcript

Hi, I’m Carla. I’m going to show you how to do head and neck exercises. Remember to do your deep abdominal breathing exercises before and after. Each exercise you will do 5 to 10 times and very important , pain free.

Neck exercises

We’ll start with the head and neck. We’ll do looking to the side, back to the middle and to the other side. It’s normal to feel a bit of stretch sensation.

Next one will be ear to the shoulder, not shoulder to the ear. Go back to the middle and to the other side. If you’re not sure you’re doing it right, sometimes it’s helpful to do it in front of a mirror.

Next one will be chin to the chest and back to start position.

Shoulder exercises

Next one will be shoulders. We’ll go up, relax and down and relax.

Next one will be circles. And we go backwards and then forward.

Mouth exercises

We’ll do as well mouth exercises. We’ll start with open and close. Blowing kisses, blowing candles, exaggerated smile. And then you say the vowels in an exaggerate way

Jaw exercises

And we’ll do as well the jaw exercises. We’ll do side to side first.

And then moving the jaw forward and the back to normal.

Remember to do the deep abdominal breathing at the end, repeat them once a day minimum and if you have any concerns just call your doctor or lymphoedema specialist.
