The organization of the motor nuclei of the glossopharyngeal, vagal, occipital, first spinal and second spinal nerves of Typhlonectes natans (Amphibia: Gymnophiona: Caeciliaidae: Typhlonectinae) was studied by using horseradish peroxidase reaction staining. Each nucleus has discrete patterns of cytoarchitecture and of topography. Nuclei are elongate and some overlap anteroposteriorly. The brain...

Greater occipital nerve block (GONB) is a common procedure to diagnose and treat patients with occipital neuralgia and to differentiate headaches of cervical origin from other types of headaches (1,2). Although a relatively safe method and easy to perform, the classical method of blind injection just medial to the palpated occipital artery at the level of the superior nuchal line is not target ...

Chronic migraine is a disabling disorder that is costly to individuals and society. Occipital nerve stimulation has been used to treat refractory cases of primary headache disorders including drug-resistant chronic cluster headaches and chronic migraine. The Food and Drug Administration (FDA) off-labeled application of equipment used for peripheral nerve (occipital) stimulation is borrowed from...

A patient with intractable postherpetic itch lasting for 1 year was reported. The itch was mainly from the left vertex, frontal and ophthalmic regions and extended to the left neck area. The patient had negative response to the ophthalmic nerve block. Under the initial positive response to the great occipital nerve block, pulsed radiofrequency (PRF) was performed on the position of the great oc...

Chronic migraine, which affects approximately 2% of the population, results in substantial costs to individual sufferers and to society (1). Current treatment options for chronic migraine are often inadequate, with a proportion of chronic migraine patients being intractable to conventional therapy. Clearly, better treatment strategies are needed to reduce the burden from this common and disabli...

We report a patient with traumatic atlanto-occipital dislocation who presented with dysphagia as the chief complaint. A 59-year-old man complained of swallowing difficulty for 2 months after trauma to the neck. On physical examination, there was atrophy of the right sternocleidomastoid and upper trapezius muscles, and the tongue was deviated to the right. In a videofluoroscopic swallowing study...

Occipital neuralgia is usually defined as paroxysmal stabbing pain in the greater or lesser occipital nerve (GON or LON) distribution. In occipital neuralgia patients, surgical considerations are carefully taken into account if medical management is ineffective. However, identification of the occipital artery by palpation in patients with thick necks or small occipital arteries can be technical...
