Trigeminal neuralgia, hemifacial spasm, vestibulocochlear neuralgia and glossopharyngeal neuralgia represent the most common neurovascular compression syndromes. Repeated vascular pulsations at the vulnerable transitional zone of the individual cranial nerves lead to focal axonal injury and demyelination. High-resolution 3-D T2-weighted MR imaging is essential in detecting and mapping neurovascular compression for directed therapy. Knowledge of the specific nerve root exit, the transitional zones, and the adjacent vasculature is critical in proper management...

INTRODUCTION: Intracranial malignant peripheral nerve sheath tumors are an extremely rare pathology with a high morbidity and mortality. Epidemiological, clinical and prognostic data are scarce and with little certainty in the literature. The aim of this paper is to report for first time in English literature, the case of a patient with type 1 neurofibromatosis, who presented a malignant peripheral nerve sheath tumor that involved the left glossopharyngeal, vagus and spinal nerves with intracranial and extracranial extension through jugular foramen and systemic metastases...

Remarkable variability between males and females occurs for an array of taste-guided behaviors in both rodents and humans. Sex differences have been noted for taste preference, detection thresholds, and reactivity to taste stimuli. Manipulating sex hormones during early postnatal development or altering the amount of circulating estrogen in adulthood can dramatically alter the pattern of these behaviors. Receptors for sex hormones appear to be prominent in several nuclei associated with central gustatory pathways, indicating that steroid hormones may modulate central taste processing...

The authors present the case of a 53-year-old man who was referred with disabling retching provoked by left arm abduction. At the time of his initial evaluation, a cervical MRI study was available for review and revealed an anatomical variation of the ipsilateral juxtamedullary vertebrobasilar junction. After brain imaging revealed contact of the medulla by a dolichoectatic vertebral artery at the dorsal root entry zone of the glossopharyngeal and vagus nerves, the patient was successfully treated by microvascular decompression of the brainstem and cranial nerves...

: Glossopharyngeal, nervus intermedius and vagus neuralgias can all present with ear pain. However, to our knowledge, there have been no reports of otalgia as the only symptom of vagus neuralgia. The seventh, ninth and tenth cranial nerves have many interneural connections and the exact anatomy and pathophysiology of these neuralgias is often not clear. Moreover, symptoms due to involvement of any of these nerves can be difficult to attribute solely to one of them. The overlapping sensory innervation of the external auditory canal can lead to misdiagnosis in patients suffering from otalgia...

Neuropathic pain encompasses a spectrum of conditions that can arise from a lesion or dysfunction of the central or the peripheral nervous system, and it may develop at variable intervals after nerve injury or inflammation. Nerve injuries arising from surgical procedures commonly occur secondary to the surgical trauma, and in rare instances they are a complication of intubation during general anesthesia or endoscopic procedures. A series of 2 cases of bilateral glossopharyngeal neuropathic pain subsequent to endoscopic procedures is presented with a review of the literature concerning the mechanisms of development of neuropathic pain after these procedures...

Acoustic neuroma resection is an example of a neurosurgical procedure where the brainstem and multiple cranial nerves are at risk for injury. Electrode placement for monitoring of the glossopharyngeal and hypoglossal nerves during acoustic neuroma resection can be challenging. The purpose of this report is to illustrate the use of a device for intra-oral electrode placement for intraoperative monitoring of the glossopharyngeal and hypoglossal nerves. A 60-year-old male presented for acoustic neuroma resection...

A 23-year-old male patient with occipitocervical fixator was scheduled for surgery due to injury to the right forearm. The patient's thyromental distance was 5 cm, mouth opening grade II, sternomental distance 10 cm and Mallampati score 4. Loss of extension and rotation movements of the head was assessed as difficult intubation criteria. Anaesthetic procedures are almost always difficult in patients with occipitocervical fixation; the limited cervical extension complicated both intubation and ventilation. In this report, application of general anaesthesia using awake fibreoptic bronchoscopic intubation (FOB) is described...

Sensory inputs from the oropharynx terminate in both the trigeminal brainstem complex and the rostral part of the nucleus of the solitary tract (nTS). Taste information is conveyed via the facial and glossopharyngeal nerves, while general mucosal innervation is carried by the trigeminal and glossopharyngeal nerves. In contrast, the caudal nTS receives general visceral information largely from the vagus nerve. Although the caudal nTS shows clear morphological and molecularly delimited subdivisions, the rostral part does not...

Airway anesthesia is pivotal for successful awake intubation provided either topically or by blocks. Airway blocks are considered technically more difficult to perform and carry a higher risk of complications. However, in experienced hands, they can be useful as they provide excellent intubating conditions. For complete upper airway anesthesia, bilateral glossopharyngeal and superior laryngeal nerve blocks with translaryngeal injection are required. Superior laryngeal nerve block and translaryngeal injection can be performed easily, safely and with a high success rate in patients with normal anatomy...

OBJECTIVE: To investigate frequencies of adverse events occurring within 30 days after microvascular decompression (MVD) surgery using a standardized report form of adverse events. METHODS: We conducted a retrospective review of 98 adult patients (≥16 years) treated with MVD between 1 January 1994 and 1 June 2013. Adverse events occurring within 30 days were classified according to the Landriel Ibanez classification for neurosurgical complications: grade I represents any non-life threatening complication treated without invasive procedures; grade II is complications requiring invasive management; grade III is life-threatening adverse events requiring treatment in an intensive care unit (ICU); grade IV is death as a result of complications...

BACKGROUND: Glossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome. It is characterized by a sudden onset lancinating pain usually localized in the sensory distribution of the IX cranial nerve associated with excessive vagal outflow, which leads to bradycardia, hypotension, syncope, or cardiac arrest. This study aims to review our surgical experience performing microvascular decompression (MVD) in patients with GPN. METHODS: Over the last 20 years, 14 consecutive cases were diagnosed with GPN...

OK-432 is an immunomodulator that has been reported to be efficacious as an injection therapy for cervical lymphomas and ranulas. We performed OK-432 injection therapy to treat a cystadenocarcinoma of the parotid gland in a 72-year-old man. The 50 × 46-mm tumor was located in the deep lobe of the gland. The tumor had compressed the glossopharyngeal, vagus, and hypoglossal nerves, causing neurally mediated syncope, hoarseness, dysphagia, and dysarthria. A concentration of 5 KE/2 ml of OK-432 was injected. Within 2 months, the cyst had disappeared; no recurrence was apparent during 59 months of follow-up...

Glossopharyngeal neuralgia is a rare pain syndrome presenting with paroxysms of pain in the region of the glossopharyngeal nerve. Even more uncommon is the association between glossopharyngeal neuralgia and cardiac syncope. In these patients, the cardiovascular consequences may include bradycardia, hypotension and cardiac arrest. We describe the case of a 40-year-old patient who presented with this rare association of glossopharyngeal neuralgia and syncope. Multiple pauses including one lasting 14 s were noted on ambulatory ECG monitoring...
