Anatomical Record, 2016 The spinal accessory nerve is often identified as a purely motor nerve innervating the trapezius and sternocleidomastoid muscles. Although it may contain proprioceptive neurons found in cervical spinal levels C2-C4, limited research has focused on the ...

The glossopharyngeal, vagus and spinal accessory nerves
European Journal of Radiology, 2010The glossopharyngeal, vagus and spinal accessory nerves are closely related anatomically, and to a certain extent, functionally. We present an overview of their anatomy, highlighting the important clinical and imaging implications. The main pathologic lesions arising from these nerves are also discussed and the imaging features reviewed.

Postirradiation neuromyotonia of spinal accessory nerves
Neurology, 2011Neuromyotonia is a rare complication of radiation therapy.1 Most reported cases involve oculomotor muscles1,2 and occur months to decades after radiation therapy. Neuromyotonia is characterized by transient involuntary tonic contractions, which occur either spontaneously or are triggered by movements, with delayed relaxation of affected muscles.3,–,5 ...

Intracranial neurilemoma of the spinal accessory nerve
Surgical Neurology, 1982Abstract The fourth example of an intracranial neurilemoma arising on the eleventh cranial nerve is reported. Review of the literature shows that cranial nerve tumors often present as mass lesions with multiple nerve involvement. Only those of the eighth and fifth cranial nerves and those arising at the jugular foramen are of numerical significance.

Spinal Accessory Nerve Lesions
Seminars in Neurology, 2009The spinal accessory nerve, primarily a motor nerve, innervates the sternocleidomastoid and trapezius muscles. Proximally, lesions can occur intracranially at the skull base or just outside the jugular foramen producing ipsilateral weakness of trapezius and sternocleidomastoid muscles; or distally, in the posterior neck triangle causing trapezius ...

Spinal accessory nerve cavernous malformation
Journal of Clinical Neuroscience, 2010We present the first reported case of a spinal accessory nerve cavernous malformation. A 54-year-old Caucasian male presented with a several-year history of progressive, vague bilateral upper and lower extremity paresthesias and pain. MRI of the spine revealed a heterogenously enhancing mass in the dorsal aspect of the spinal canal at the level of the ...

A Novel Approach to Identifying the Spinal Accessory Nerve in Surgical Neck Dissection
Otolaryngology - Head and Neck Surgery, 2018 Intraoperative identification of the spinal accessory nerve (SAN) is key in reducing nerve injury. This study aims to explore the surgical anatomy of the SAN and 2 landmarks for its identification—the sternocleidomastoid branch of the occipital artery ...

Clinical Orthopaedics and Related Research, 1975
In 7 cases of peripheral lesion of the spinal accessory nerve 4 were produced by malignancy, two by iatrogenical resection of lymph nodes, one by an en bloc dissection of the neck for arteriovenous malformation. Incapacity following the injury is quite marked and includes weakness of the sternomastoid and trapezius muscles, as well as pain presumably ...

Extracranial Spinal Accessory Nerve Injury
Neurosurgery, 1993Eighty-three consecutive patients with extracranial accessory nerve injury seen over a 12-year period are reviewed. The most common etiology was iatrogenic injury to the nerve at the time of previous surgery. Such operations were usually minor in nature and often related to lymph node or benign tumor removal.

Journal of Hand Surgery: European Volume, 2018 Spinal accessory nerve grafting requires identification of both nerve stumps in the scar tissue, which is sometimes difficult. We propose a direct nerve transfer using a fascicle from the posterior division of the upper trunk.
