Spinal accessory nerve neuropathy following neck dissection

Abstract: Tt he most common complication of neck dissection is shoulder dysfunction due to manipulation of spinal accessory nerve, resulting in trapezius muscle atrophy mainly in procedures involving the posterior neck triangle.Aim: This study used electromyography to evaluate the injury to the spinal accessory nerve following neck dissection.Materials and methods: prospective case series of 51 patients submitted to 60 neck dissections followed by physical therapy evaluation of shoulder dysfunction. nerve integrity was … Show more

“…This is similar to our findings of 35 cases observed over 21 years. In contrast, patients with unilateral TM palsy due to surgery, especially selective neck dissection are numerous . Patients with unilateral TM palsy usually complain of some pain and especially major weakness of the upper limb when lifting and when they attempt upper limb elevation.…”

“…Anatomically, this nerve is closely linked to the neck lymphatic drainage, in the lateral cervical region, and the removal of lymph nodes for diagnostic/treatment purposes can cause a lesion or praxis to the SAN . Lima et al assessed SAN neuropathy upon neck dissection, which included an electroneuromyographic examination, and found the upper fibers of the trapezius muscle to be affected with pain and limited abduction of the arm in all patients evaluated after surgery. In this study, we did not perform a functional assessment of the SAN and this can be a limitation on finding the possible association of SAN function and the myofascial pain syndrome.…”
