Neck Dissection

Neck dissection is an operation to remove lymph nodes from one side or both sides of the neck. It may be planned when scans or examination suggest cancer has reached neck nodes, or when nodes need careful examination after removal. The surgeon chooses the extent according to the tumour location and findings.

The operation is performed under general anaesthesia. Some nearby structures may be preserved, while tissue that is involved or at risk may need removal. A pathology team examines the specimens and the result helps guide further care for Head and Neck Cancer or Mouth Cancer.

Before surgery, your team reviews imaging, examines your neck, discusses medicines, and explains the planned incision and possible changes to the operation. During surgery, lymph nodes are removed through an incision in the neck; a drain is commonly placed to collect fluid while the wound begins to heal. The tissue is sent for pathology.

Expected effects include neck soreness, swelling, numbness around the scar, tightness, and reduced shoulder movement. A nerve near the shoulder may be bruised or deliberately sacrificed depending on disease involvement, causing shoulder weakness. Ask about physiotherapy and wound care before leaving hospital.

Contact the surgical team promptly for increasing redness, wound opening, persistent drainage, fever, breathing difficulty, sudden swelling, or new weakness. These symptoms can signal infection, bleeding, a fluid collection, or nerve-related problems and need assessment.

The operation provides tissue that can show whether lymph nodes contain cancer and how extensively they are involved. That information helps the team decide whether observation, Radiotherapy, or another treatment is appropriate. The outlook depends on the original cancer, node findings, overall health, and treatment plan; surgery alone cannot predict an individual result.

Neck dissection can be selective, modified, or more extensive. The name describes how much tissue is removed, not a promise about the final pathology result. A drain and a temporary change in neck sensation are common parts of recovery.

A neck dissection may be offered to people with head and neck cancers when a neck node is enlarged, imaging raises concern, or the cancer has a meaningful risk of hidden node involvement. The decision considers tumour site, stage, scan findings, prior treatment, and whether surgery is part of the wider plan.

The team marks the surgical side, gives anaesthesia, makes the planned neck incision, identifies and protects important structures where possible, removes the selected nodal levels, checks bleeding, and closes the wound with a drain when needed. The specimen then goes to pathology.

Hospital recovery varies with the extent of surgery and any combined procedure. Eating, drinking, pain control, drain output, and shoulder movement are checked before discharge. At home, keep the incision clean as instructed, avoid strenuous activity until cleared, and attend review when pathology and wound progress are discussed. Sensation and shoulder function can improve gradually, with exercises supporting movement.

Possible risks include bleeding, infection, a fluid collection, visible scarring, numbness, reduced neck or shoulder movement, and injury to nerves or blood vessels. The risk profile changes when nearby tissue is involved or when neck dissection is combined with another operation.

Depending on the cancer and scan findings, options may include careful monitoring, a different surgical extent, Radiotherapy, systemic treatment, or a combination. Your team weighs control of cancer against effects on movement, swallowing, appearance, and daily function.

Look for a head and neck cancer team that includes an experienced surgeon, radiologist, pathologist, oncology specialists, and rehabilitation support. At consultation, ask which nodal levels are planned, which nerves or muscles are at risk, how shoulder function will be supported, and when pathology results will be reviewed.
