The mandibular canal (MC) contains vessels and nerves in the mandible of the Japanese macaque (JM). The inferior alveolar nerves and vessels of the mandible insert from the mandibular foramen and then run through the MC, the mental foramen and spinal foramen to the outside of the mandible. However, the detailed morphological properties of multiple canals, such as the accessory canal (AC) of the mandible, are unknown in JMs. The purpose of this study was to describe the multiple canals of JMs and to determine the location and analyse the measurements of the JM mandible...

Oral cavity carcinoma is the most common cancer in Indian population. Metastatic nodal disease is the most important prognostic factor for oral cancers. In head and neck cancers with clinically N0 neck, standard selective neck dissection is performed by protecting the spinal accessory nerve to remove level IIA & IIB lymph nodes. The purpose of this study was to analyze the significance of level IIB dissection in patients of oral cavity cancer who underwent primary surgery with functional neck dissection. Two hundred ten patients with clinically N0 neck underwent neck dissection, where level IIB lymph nodes were dissected, labelled and processed separately...

We compared outcomes of primary vascularized ulnar nerve grafts from the C5 root neurotizing biceps and brachialis muscles, and gracilis functioning free muscle transfer neurotized by the distal spinal accessory nerve, as a primary or salvage procedure after complete brachial plexus injury. At 45 months, three of eight primary vascularized ulnar nerve graft patients regained grade 4 elbow flexion, while one regained grade 3. All 13 primary gracilis transfer patients regained grade 4 elbow flexion. Four patients with vascularized ulnar nerve grafts failed and subsequently had salvage functioning free muscle transfer procedures resulting in delayed recovery...

BACKGROUND: Botulinum is a potent neurotoxin with increasing indications for neurologic disorders. While clinical benefit manifests primarily due to local actions at the neuromuscular junction, regional and systemic effects do occur. Rarely, systemic symptoms including weakness, dysarthria, dysphagia and other side effects occur as a result of iatrogenic botulinum neurotoxicity. CASE: A 72 year-old female with right leg dystonia developed head drop, bulbar and systemic weakness following right lower extremity botulinum toxin injection...

PURPOSE: After complete 5-level root avulsion brachial plexus injury, the free-functioning muscle transfer (FFMT) and the intercostal nerve (ICN) to musculocutaneous nerve (MCN) transfer are 2 potential reconstructive options for restoration of elbow flexion. The aim of this study was to determine if the combination of the gracilis FFMT and the ICN to MCN transfer provides stronger elbow flexion compared with the gracilis FFMT alone. METHODS: Sixty-five patients who underwent the gracilis FFMT only (32 patients) or the gracilis FFMT in addition to the ICN to MCN transfer (33 patients) for elbow flexion after a pan-plexus injury were included...

Leigh syndrome (LS) is an early-onset progressive neurodegenerative disorder, characterized by a wide clinical and genetic heterogeneity, and is the most frequent disorder of mitochondrial energy production in children. Beside its great variability in clinical, biochemical, and genetic features, LS is pathologically uniformly characterized by multifocal bilateral and symmetric spongiform degeneration of the basal ganglia, brainstem, thalamus, cerebellum, spinal cord, and optic nerves. Isolated complex I deficiency is the most common defect identified in Leigh syndrome...

BACKGROUND: Posterior inferior cerebellar artery (PICA) aneurysms are often located in the ventral craniocervical junction. Such deep-seated aneurysms are usually treated with coil embolization. However, recurred and/or very small PICA aneurysms are hardly treated with an endovascular approach. METHOD: We present a modification of the transcondylar fossa approach with intradural and extradural removal of the jugular tubercle. An adequate preaccessory surgical corridor was created with this novel technique...

Background: Conventional wisdom and the available literature demonstrate compromised outcomes following nerve reconstruction for traumatic brachial plexus palsy in the elderly. We present a 74-year-old male who was reconstructed with multiple nerve transfers for brachial plexus palsy after a ski accident. Methods: Triceps to axillary nerve transfer, spinal accessory to suprascapular nerve transfer, and ulnar to musculocutaneous nerve transfer were performed 16 weeks post injury. Results: At 11 years post-op, the patient could abduct to 65° and forward flex at M4 strength, limited only by painful glenohumeral arthritis...

Scapular winging represents a rare phenomenon that most commonly results from nerve damage to either the long thoracic nerve, spinal accessory nerve, or, less commonly, the dorsal scapular nerve. This injury results in an abnormal scapulohumeral interaction during kinetic motion known as scapular dyskinesis. In this case report, the patient presented with scapular dyskinesis and medial scapular winging caused by overhead weight-lifting exercises, and a long thoracic nerve injury was diagnosed. Physicians are encouraged to consider long thoracic nerve damage in a patient with a history of repetitive overhead movements who presents with scapular dyskinesis and the corresponding restriction of overhead arm motions...

PURPOSE OF REVIEW: Despite nerve-sparing surgery, postoperative shoulder morbidity remains high and significantly impacts patient's quality of life. This review will focus on recent findings of anatomical nuances of the cranial nerve XI (CN XI) along its course in the neck and possible reasons for postoperative morbidity. RECENT FINDINGS: The most recent studies identified three different branching patterns of the CN XI in the neck. In type 1 (66%), the branch for trapezius muscle exits at the posterior border of the sternocleidomastoid muscle (mSCM)...

The aim of surgery for pterygium colli (PC) is to correct the contour deformity, redistribute or remove the horizontal excess of skin, address the abnormal posterior hairline, avoid excessive scarring, and prevent recurrence. The purpose of this study is to review the available methods to correct the deformity and highlight a recent patient performed by the senior author. A modified bilateral Z-plasty technique was used for correcting PC on a 5-year-old African American girl diagnosed with Turner syndrome. The patient had an uneventful postoperative period and satisfactory functional and esthetic results were demonstrated at 1 year follow-up...

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...

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...
