What is a common complication following a radical neck dissection regarding the trapezius muscle?

A radical neck dissection involves the surgical removal of lymph nodes and surrounding structures, including the sternocleidomastoid muscle, internal jugular vein, and sometimes the spinal accessory nerve, which innervates the trapezius muscle.

Following this procedure, it is common for patients to experience decreased shoulder function due to weakness or paralysis of the trapezius muscle. This can lead to limited shoulder elevation and impaired overall shoulder mechanics. Due to the anatomical changes and potential nerve involvement, the stability and mobility of the shoulder girdle can be significantly affected.

Chronic pain syndrome can also arise as a complication post-surgery. Patients might experience neuropathic pain due to nerve damage or irritation during the dissection. This pain can persist long after the surgical site has healed, impacting the quality of life.

Hematoma formation is another potential complication that could occur following a radical neck dissection, resulting from bleeding in the surgical area. While it is a significant concern, it is one of several complications associated with this extensive surgical procedure.

Given the multifaceted nature of complications that can arise following a radical neck dissection, the correct answer encompasses all these aspects, indicating that decreased shoulder function, chronic pain syndrome, and hematoma formation can each occur
