What Is Cervical Lymphadenectomy?

Cervical lymphadenectomy is surgery that removes lymph nodes from one or more regions of the neck for cancer treatment or staging. It is also commonly called neck dissection. The extent can range from selective removal of specific nodal levels to more extensive modified radical or radical dissections. The operation is tailored to the primary cancer, pattern of lymphatic spread, imaging findings, and whether lymph nodes are clinically involved.

Why Is Cervical Lymphadenectomy Performed?

The procedure is used when cancer has spread to cervical lymph nodes or when the risk of microscopic nodal disease is high enough to justify surgical removal. It is commonly associated with cancers of the oral cavity, pharynx, larynx, thyroid, salivary glands, and skin of the head and neck. Surgeons choose which nodal levels to remove according to the expected lymphatic drainage pattern of the primary tumor. Pathologic examination of the removed nodes also helps determine cancer stage and the need for additional treatment.

How Is Cervical Lymphadenectomy Performed?

The surgeon makes a neck incision and removes lymphatic tissue from the planned cervical nodal levels while protecting major nerves, muscles, and blood vessels whenever oncologically safe. Selective neck dissection removes only the nodal groups at greatest risk, while more extensive operations remove additional levels and can sacrifice involved non-lymphatic structures. Drains are commonly placed to remove blood and lymphatic fluid during early healing. The procedure can be performed on one or both sides of the neck depending on the disease pattern.

What Is Recovery Like After Cervical Lymphadenectomy?

Recovery includes incision care, drain management, pain control, neck movement, and monitoring for bleeding, infection, or lymphatic leakage. Shoulder stiffness or weakness can occur when the spinal accessory nerve is dissected, stretched, or removed. Physical therapy can help restore shoulder range, strength, posture, and neck mobility. Further radiation therapy, systemic therapy, radioactive iodine, or surveillance can be recommended according to the primary cancer and lymph-node pathology.

What Are the Risks and Complications?

Possible complications include bleeding, hematoma, infection, seroma, chyle leak, numbness, neck stiffness, and shoulder dysfunction. Nerves at risk can include the spinal accessory, marginal mandibular, vagus, hypoglossal, phrenic, sympathetic, and sensory cervical nerves depending on the dissection. Injury to the internal jugular vein, carotid artery, thoracic duct, or other major structures can cause serious complications. Lymphedema, chronic tightness, or altered sensation can persist after extensive neck-node surgery or radiation.

Frequently Asked Questions About Cervical Lymphadenectomy

Is cervical lymphadenectomy the same as neck dissection?

Yes. Cervical lymphadenectomy is a general medical term for surgical removal of neck lymph nodes and is commonly referred to as neck dissection.

What are cervical lymph-node levels?

The neck is divided into numbered nodal levels that correspond to defined anatomical regions. These levels help surgeons plan which lymph-node groups need removal.

Does every neck dissection remove the same lymph nodes?

No. Selective, modified radical, and radical dissections remove different nodal groups and non-lymphatic structures according to cancer location and extent.

Can shoulder weakness occur after cervical lymphadenectomy?

Yes. The spinal accessory nerve can be stretched, manipulated, or removed during some dissections, which can weaken the trapezius and limit shoulder movement.
