BACKGROUND: Using functioning free muscle transplantation (FFMT) for facial paralysis and postparalysis facial synkinesis reconstruction is our preferred technique. Gracilis was the first choice of muscle. Three motor neurotizers: cross-face nerve graft (CFNG), spinal accessory nerve (XI) and masseter nerve (V3) have been used as neurotizers for different indications. METHODS: A total of 362 cases of facial reanimation with FFMT were performed between 1986 and 2015...

The spinal accessory nerve arises from motor neurons in the upper cervical spinal cord. The axons of these motor neurons exit dorsal to the ligamentum denticulatum and form the spinal accessory nerve. The nerve ascends in the spinal subarachnoid space to enter the posterior cranial fossa through the foramen magnum. The spinal accessory nerve then turns caudally to exit through the jugular foramen alongside the vagus and glossopharyngeal nerves, and then travels to supply the sternomastoid and trapezius muscles in the neck...

PURPOSE: This study attempted to define a reproducible "safe zone" based on extra- and intra-articular knee anatomy for placing one or 2 accessory portals in the lateral tibiofemoral compartment for posterolateral region viewing. METHODS: Standard portals were created in 10 cadaveric knees to enable posterolateral region arthroscopic lateral tibiofemoral joint compartment viewing. After identifying the lateral knee surface tissue "soft spot," an accessory posterolateral portal (A) was created using an 18-gauge spinal needle and 4-mm cannula under direct visualization of a 70° arthroscope through the anteromedial portal...

OBJECTIVE: Spasmodic torticollis (ST) is an idiopathic neurologic disorder affecting the muscles of the neck. Surgery is a preferred treatment, when conservative treatments or Botulinum neurotoxin injections fail to relieve the symptoms. Our objective here is to report the outcome of a new surgical method for treating ST patients in our department. METHODS: The new procedure consists of rhizotomy of the spinal accessory nerve (SAN) and C1-C2 nerve roots, coagulation of the distal end of SAN (Group A)...

In reanimation surgery, effortless smile can be achieved by a nonfacial donor nerve. The underlying mechanisms for this smile development, and which is the best nonfacial neurotizer, need further clarification. The aim of the present study was therefore to further explore the natural coactivation between facial mimic muscles and muscles innervated by the most common donor nerves used in smile reanimation. The study was conducted in 10 healthy adults. Correlation between voluntary facial muscle movements and simultaneous electromyographic activity in muscles innervated by the masseter, hypoglossal, and spinal accessory nerves was assessed...

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 (SBOA) and superior sternocleidomastoid tendon (SST)-to propose a novel method of identifying the SAN during surgical neck dissections. Twelve cadavers underwent bilateral level II-V neck dissection identifying the SAN, SBOA, and SST. Variation was documented and distance between landmarks and the SAN measured...

Painful neurogenic hypertrophy is a rare complication of radiation therapy. We report a 27-year-old woman with a history of adenoid cystic carcinoma of the submandibular gland presented with painful twitching of her left shoulder. Electrodiagnostic studies were consistent with a diagnosis of radiation-induced spinal accessory nerve hyperactivity. The patient failed conventional medical therapy. She was treated with an injection of botulinum toxin A, and within 1 month experienced significant relief of symptoms...

Cervical spondylotic amyotrophy is characterized by severe, proximal upper extremity weakness including an inability to abduct the shoulder and flex the elbow. Treatment using both medical and surgical decompression approaches has produced variable results. This paper reports the use of nerve transfers (spinal accessory to suprascapular, flexor carpi ulnaris fascicle of ulnar to biceps motor branch, radial nerve branch to triceps to axillary) to restore shoulder and elbow function in a case of unilateral cervical spondylotic amyotrophy involving C5 and C6 myotomes...

Treatment sequelae such as trismus, shoulder dysfunction syndrome resulting from spinal accessory nerve palsy, and radiotherapy-induced neck fibrosis are often overlooked when in the management of head and neck cancer patients. This chapter examines these underappreciated issues and their corresponding physical therapy intervention based on current evidence. Head and neck cancer survivors must contend with these disabilities for years after treatment has been concluded. A few quit their jobs which puts a tremendous burden on them and their families with a diminished quality of life...

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. We retrospectively reviewed 11 patients with trapezius palsy due to an iatrogenic injury of the spinal accessory nerve in nine cases. The mean age was 38 years (range 21-59). Preoperatively, patients showed shoulder weakness and limited range of motion. At a mean follow-up of 25 months, active shoulder abduction improvement averaged 57°...

OBJECTIVE Spinal accessory nerve (SAN) injury results in a series of shoulder dysfunctions and continuous pain. However, current treatments are limited by the lack of donor nerves as well as by undesirable nerve regeneration. Here, the authors report a modified nerve transfer technique in which they employ a nerve fascicle from the posterior division (PD) of the ipsilateral C-7 nerve to repair SAN injury. The technique, first performed in cadavers, was then undertaken in 2 patients. METHODS Six fresh cadavers (12 sides of the SAN and ipsilateral C-7) were studied to observe the anatomical relationship between the SAN and C-7 nerve...

BACKGROUND: Schwannoma of the hypoglossal nerve is rare. This case report documents an atypical abnormality of the cervical vestibular evoked myogenic potential (cVEMP) in a patient with schwannoma of the hypoglossal nerve. The observed abnormality was attributed to the proximity of the hypoglossal nerve to the spinal accessory nerve in the medullary cistern and base of the skull. PURPOSE: To report cVEMP abnormality in a patient with hypoglossal nerve schwannoma and provide an anatomical correlation for this abnormality...

BACKGROUND: Shoulder dysfunction is common after neck dissection for head and neck cancer (HNC). Brief electrical stimulation (BES) is a novel technique that has been shown to enhance neuronal regeneration after nerve injury by modulating the brain-derived neurotrophic growth factor (BDNF) pathways. The objective of this study was to evaluate the effect of BES on postoperative shoulder function following oncologic neck dissection. METHODS: Adult participants with a new diagnosis of HNC undergoing Level IIb +/- V neck dissection were recruited...

Multiple techniques have been developed for the electrodiagnostic evaluation of cranial nerves XI and XII. Each of these carries both benefits and limitations, with more techniques and data being available in the literature for spinal accessory than hypoglossal nerve evaluation. Spinal accessory and hypoglossal neuropathy are relatively uncommon cranial mononeuropathies that may be evaluated in the outpatient electrodiagnostic laboratory setting. A review of available literature using PubMed was conducted regarding electrodiagnostic technique in the evaluation of spinal accessory and hypoglossal nerves searching for both routine nerve conduction studies and repetitive nerve conduction studies...

Particularly challenging after complete brachial plexus avulsion is reestablishing effective hand function, due to limited neurological donors to reanimate the arm. Acute repair of avulsion injuries may enable reinnervation strategies for achieving hand function. This patient presented with pan-brachial plexus injury. Given its irreparable nature, the authors recommended multistage reconstruction, including contralateral C-7 transfer for hand function, multiple intercostal nerves for shoulder/triceps function, shoulder fusion, and spinal accessory nerve-to-musculocutaneous nerve transfer for elbow flexion...

CASE: A 37-year-old man with scapular winging, caused by combined palsy of the spinal accessory nerve and the long thoracic nerve, was successfully treated with a pectoralis major transfer to substitute for the serratus anterior muscle, and with levator scapulae and rhomboid muscle transfers to substitute for the trapezius muscle. CONCLUSION: The serratus anterior paralysis was thought to have occurred secondary to traction of the long thoracic nerve by the unsupported scapula following the spinal accessory nerve palsy...

The spinal accessory nerve (SAN) or XI cranial nerve is frequently encountered during neck surgery, and as such is at risk of iatrogenic injury, resulting in "shoulder syndrome". Modified neck dissection (MND) with preservation of the SAN is based on desire to minimise the functional deformity associated with section of the eleventh nerve. The aim of this study was to analyse the intra-operative variations of the spinal accessory nerve pathway and to evaluate shoulder dysfunction postoperatively. The cross-sectional demonstration analysis was created through the medical records retrospectively of 165 consecutive patients who underwent neck dissections at our institution in the past 5 years with attention to ultrasound and MRI preoperative findings, type of neck dissection, type of identification and dissection of SAN, postoperative morbidity and survival rate...
