Dwight Baldoman, Ron Vandenbrink
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...

BACKGROUND: Injury to long thoracic and the spinal accessory nerves can cause winging scapula as a result of weakness and paralysis of the trapezius and serratus anterior muscles. Although these nerve and muscle operations have been reported to correct winging scapula due to various causes, there is no report on comparing the outcomes of these procedures in peer-reviewed Pubmed-indexed literature. In this article, we compared the improvements in the restoration of shoulder functions in winging scapula patients after long thoracic nerve decompression (LTND) in our present study with outcomes of muscle and tendon transfer operations published in the literature (Aetna cited articles)...

OBJECTIVE The dura mater is made of 2 layers: the endosteal layer (outer layer), which is firmly attached to the bone, and the meningeal layer (inner layer), which directly covers the brain and spinal cord. These 2 dural layers join together in most parts of the skull base and cranial convexity, and separate into the orbital and perisellar compartments or into the spinal epidural space to form the extradural neural axis compartment (EDNAC). The EDNAC contains fat and/or venous blood. The aim of this dissection study was to anatomically verify the concept of the EDNAC by focusing on the dural layers surrounding the jugular foramen area...

The shoulder pain syndrome is the most frequent complication of lateral cervical neck dissection and may be caused by iatrogenic injury to the spinal accessory nerve, causing pain and functional limitation of the upper limb and of the cervical spine. Interdisciplinary collaboration and early rehabilitation can reduce the consequences of disability and the possible issues that can arise due to inadequate management of the problem.

OBJECTIVE Pan-brachial plexus injury (PBPI), involving C5-T1, disproportionately affects young males, causing lifelong disability and decreased quality of life. The restoration of elbow flexion remains a surgical priority for these patients. Within the first 6 months of injury, transfer of spinal accessory nerve (SAN) fascicles via a sural nerve graft or intercostal nerve (ICN) fascicles to the musculocutaneous nerve can restore elbow flexion. Beyond 1 year, free-functioning muscle transplantation (FFMT) of the gracilis muscle can be used to restore elbow flexion...

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...
