: In upper (C5-C7) and total (C5-T1) root avulsion brachial plexus injury, a method of double neurotization from a single donor spinal accessory nerve to two target nerves (suprascapular nerve and axillary nerve) may be done, leaving donor nerves available for reconstruction procedures to restore other aspects of upper limb function. A mean range of shoulder abduction of 91° (SD 25°) was achieved through this procedure in our study of 13 cases, of which seven cases were C5-C7 root avulsion and six cases were C5-T1 root avulsion brachial plexus injuries...

The inner thoracic cavity is lined by the parietal pleura, and the lung lobes are covered by the visceral pleura. The parietal and visceral plurae form the pleural cavity that has negative pressure within to enable normal respiration. The lung tissues are bilaterally innervated by vagal and spinal nerves, including sensory and motor components. This complicated innervation pattern has made it difficult to discern the vagal vs. spinal processes in the pulmonary visceral pleura. With and without vagotomy, we identified vagal nerve fibres and endings distributed extensively in the visceral pleura ('P'-type nerve endings) and triangular ligaments ('L'-type nerve endings) by injecting wheat germ agglutinin-horseradish peroxidase as a tracer into the nucleus of solitary tract or nodose ganglion of male Sprague-Dawley rats...

BACKGROUND: Shoulder complaints are frequently reported after surgical treatment for thyroid carcinoma. However, no specific literature on this topic is available for these patients and, hence, its impact on quality of life (QOL) is unknown and there are no known predictors of shoulder complaints in this specific patient population. Therefore, the purpose of this study was to assess the prevalence of shoulder-related complaints and its relation to QOL and clinical characteristics after thyroid carcinoma surgery by means of a cross-sectional case control study in a tertiary referral center...

J-N Goubier, F Teboul
Recovery of shoulder function is a real challenge in cases of partial brachial plexus palsy. Currently, in C5-C6 root injuries, transfer of the long head of the triceps brachii branch is done to revive the deltoid muscle. Spinal accessory nerve transfer is typically used for reanimation of the suprascapular nerve. We propose an alternative technique in which the nerve of the rhomboid muscles is transferred to the suprascapular nerve. A 33-year-old male patient with a C5-C6 brachial plexus injury with shoulder and elbow flexion palsy underwent surgery 7 months after the injury...

PURPOSE: The great auricular point (GAP) marks the exit of the great auricular nerve at the posterior border of the sternocleidomastoid muscle (SCM). It is a key landmark for the identification of the spinal accessory nerve, and its intraoperative localization is vital to avoid neurological sequelae. This study delineates the topography and surface anatomy landmarks that used to localize the GAP. METHODS: Thirty cadaveric heminecks were dissected on a layer-by-layer approach...

INTRODUCTION: Facial reanimation surgery is performed in severe cases of facial palsy to restore facial function. In a 1-stage procedure, the spinal accessory nerve can be used as a donor nerve to power a free gracilis muscle transplant for the reanimation of the mouth. The aim of this study was to describe the surgical anatomy of the spinal accessory nerve, provide a guide for reliable donor nerve dissection, and analyze the available donor axon counts. METHODS: Dissections were performed on 10 nonembalmed cadavers (measurements of 20 nerves)...

INTRODUCTION: Harmonic scalpel is being increasingly used in neck dissection as alternative to conventional electro-cautery for achieving haemostasis. Use of harmonic scalpel has been shown to significantly reduce intra operative blood loss and intra operative time in neck dissection. But how safe is it with regards to nerve injury (spinal accessory nerve and other nerves) during neck dissection. We intended to study the spinal accessory nerve injury during neck dissection by both harmonic scalpel and electro cautery technique and compared postoperative recovery of shoulder function after neck dissection...

Nodal metastases is the most important prognostic marker for oral cavity cancers. Nodal dissection at level IIb risks damage to the spinal accessory nerve. We aim to study positivity of level IIb lymph nodes in oral cancers. In this non-randomized prospective observational study, 65 patients of oral cavity cancers were evaluated. Appropriate surgery for primary tumour and neck dissection were undertaken. All patients underwent level II b dissection. Out of 67 neck dissections (27 elective and 40 therapeutic), 7 patients had level IIb positive for metastases (10...

Spinal accessory nerve (SAN) injury results in loss of motor function of the trapezius muscle and leads to severe shoulder problems. Primary end-to-end or graft repair is usually the standard treatment. The authors present 2 patients who presented late (8 and 10 months) after their SAN injuries, in whom a lateral pectoral nerve transfer to the SAN was performed successfully using a supraclavicular approach.

BACKGROUND: Anatomical variants of the spinal root of the accessory nerve and cervical plexus are well known but other variants are exceptionally rare. METHODS: A prospective study of 160 selective neck dissections was undertaken following an index case, where a presumed C1 nerve (travelling with the hypoglossal nerve) was found to innervate sternocleidomastoid (SCM). A search was subsequently made for this variant while not compromising the neck dissection surgery itself...

Two horses from Saskatchewan were presented with signs of sweating, muscle fasciculations, weight loss, and generalized weakness. The horses were diagnosed with equine motor neuron disease (EMND), by histological assessment of a spinal accessory nerve or sacrocaudalis dorsalis medialis muscle biopsy. This is the first report of EMND in western Canada.

BACKGROUND: For the reconstruction of brachial plexus lesions, restoration of elbow flexion and shoulder function is fundamental and is achieved by dual nerve transfers. Shoulder stabilization and movement are crucial in freedom of motion of the upper extremity. In patients with C5-C6 brachial plexus injury, spinal accessory nerve transfer to the suprascapular nerve and a fascicle of ulnar nerve to musculocutaneous nerve (dual nerve transfer) are carried out for restoration of shoulder abduction and elbow flexion, respectively...
