The topographical relationships among the lower cranial nerves, internal carotid artery (ICA), and internal jugular vein (IJV) in the upper parapharyngeal neurovascular bundle remain obscure. Thus, details of the anatomy were examined in human fetus histology. We observed the horizontal histological sections from 20 midterm (9-18 weeks) and 12 near-term (28-40 weeks) fetuses. At the external skull base, the glossopharyngeal nerve crosses the anterior aspect of the IJV to reach the medially located Hyrtl's fissure in the petrous temporal bone...

OBJECTIVE: Glossopharyngeal nerve block is a useful interventional technique for pain management of the head and neck. It is performed with landmark techniques or ultrasound guidance. We propose a novel ultrasound-guided glossopharyngeal nerve block technique. METHODS: This new approach was performed in 3 patients in their twenties and thirties. A needle was inserted deeply under the stylohyoid muscle through the sternocleidomastoid muscle. Subsequently, an ultrasound-guided nerve block was performed with 1 mL of 1% xylocaine...

INTRODUCTION: Microvascular decompression (MVD) surgery is the first choice treatment for refractory cranial neuralgia secondary to vascular compression. Simultaneous neuralgia of two cranial nerves is extremely rare. We describe a case of concomitant refractory trigeminal (TN) and glossopharyngeal (GN) neuralgia secondary to neurovascular crossover, treated surgically at the same time. CASE REPORT: 65-year-old woman with right TN (initially V2-V3) since 2004 with regular control with carboxamides...

The brainstem houses neuronal circuits that control homeostasis of vital functions. These include the depth and rate of breathing1 , 2 and, critically, apnea, a transient cessation of breathing that prevents noxious vapors from entering further into the respiratory tract. Current thinking is that this reflex is mediated by two sensory pathways. One known pathway involves vagal and glossopharyngeal afferents that project to the nucleus of the solitary tract.3 , 4 , 5 Yet, apnea induced by electrical stimulation of the nasal epithelium or delivery of ammonia vapors to the nose persists after brainstem transection at the pontomedullary junction, indicating that the circuitry that mediates this reflex is intrinsic to the medulla...

Ramsay Hunt syndrome is a clinical manifestation of the reactivation of latent varicella zoster virus in the geniculate ganglion after acute infection. It is commonly associated with an acute peripheral facial nerve paralysis, auricular vesicular eruption and acute sensorineural hearing loss. However, in some rare cases the involvement of other cranial nerves, especially the glossopharyngeal and vagal is described. We present a 56-year-old male patient who was diagnosed with acute pharyngitis. Two days later, the patient developed dysarthria, hoarseness, and left side facial weakness...

A complete second branchial fistula is very rare and has an internal opening at the tonsillar fossa and an external opening at the lower third of the sternocleidomastoid (SCM). Patients commonly present with persistent or intermittent mucoid or mucopurulent discharge from an external opening. The diagnosis is most often clinical and radiological investigations are rarely needed. Treatment of choice is complete surgical excision. The aim of this article is to aware young ENT surgeons of the various clinical and intraoperative surgical findings that can be encountered while dealing with these cases...

A 7-year-old castrated male American Shorthair cat presented with left-side Horner's syndrome and voice change. The overall clinical presentation included dysphagia, intermittent coughing, unilateral miosis, and third eyelid protrusion of the left eye. A topical 1% phenylephrine was applied, and miosis and protrusion of the third eyelid disappeared within 20 min which suggested a post-ganglionic lesion. Laryngoscopy showed left-sided laryngeal paralysis. Computed tomography (CT) identified a mass lesion invading outside of the left tympanic bulla with osteolysis...

INTRODUCTION AND IMPORTANCE: Schwannomas are tumors of the nerve sheath that consist of Schwann cells that are often described as slow-growing. Glossopharyngeal schwannomas are rare tumors present in the region of the posterior fossa, with limited case reports present in literature. While patients may present asymptomatically, some present with vestibulocochlear symptoms or lower cranial nerve dysfunction. CLINICAL PRESENTATION: We report an extremely rare case of a left para-pharyngeal carotid space glossopharyngeal schwannoma in a 26-year-old female...

Ramsay Hunt syndrome is a facial nerve palsy that arises from herpes zoster infection. In rare cases, postherpetic neuralgia is a complication following Ramsay Hunt syndrome. Pain management to address postherpetic neuralgia includes facial nerve blocks, medications such as gabapentin, carbamazepine and botulinum toxin injections, and pulsed radiofrequency. Despite the reported benefits for patients with glossopharyngeal nerve pain, neurectomy as a treatment has rarely been described. A 45-year-old patient visited our ENT clinic for chronic right-sided facial, ear, and jaw pain that persisted for 9 years following the development of Ramsay Hunt syndrome...

The upper airway (nasal passages, paranasal sinuses, pharynx, and glottis) provides the sentinel portion of the human respiratory tract, with the combined senses of olfaction (cranial nerve I) and trigeminal sensation (cranial nerve V) signaling the quality of inspired air. Trigeminal function also complements the sense of taste (in turn mediated by cranial nerves VII, IX and X), and participates in the genesis of taste aversions. The ability of trigeminal stimulation in the upper aero-digestive tract to trigger a variety of respiratory and behavioral reflexes has long been recognized...

BACKGROUND: The neck has been implicated as a potential generator of symptoms such as dizziness and headache in individuals with persistent symptoms post concussion. Anatomically, the neck could also be a potential trigger for autonomic or cranial nerve symptoms. The glossopharyngeal nerve which innervates the upper pharynx is one possible autonomic trigger that might be affected by the upper cervical spine. CASE DESCRIPTION: This is a case series of three individuals with persistent post-traumatic headache (PPTH) and symptoms of autonomic dysregulation who also had signs of intermittent glossopharyngeal nerve irritation associated with certain neck positions or movements...

Glossopharyngeal neuralgia (GPN) is an uncommon facial pain syndrome and is characterized by paroxysms of excruciating pain in the distributions of the auricular and pharyngeal branches of cranial nerves IX and X. Glossopharyngeal neuralgia characterized by otalgia alone is rare. Herein, the authors analyzed 2 patients with GPN with otalgia as the main clinical manifestation. The clinical features and prognosis of this rare group of patients with GPN were discussed. They both presented with paroxysmal pain in the external auditory meatus and preoperative magnetic resonance imaging suggested the vertebral artery were closely related to the glossopharyngeal nerves...

BACKGROUND: Glossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome. Although rare, it is occasionally associated with cardiac syncope, as vago-glossopharyngeal neuralgia (VGPN). CASE DESCRIPTION: We present the case of a 73-year-old man with VGPN misdiagnosed as trigeminal neuralgia. The patient was diagnosed with sick sinus syndrome, and a pacemaker was introduced. However, syncope still recurred. Magnetic resonance imaging revealed a branch of the right posterior inferior cerebellar artery contacting the root exit zone of the right glossopharyngeal and vagus nerves...

Schwannomas (neurilemomas) are benign, slow-growing, encapsulated, white, yellow, or pink tumors originating in Schwann cells in the sheaths of cranial nerves or myelinated peripheral nerves. Facial nerve schwannomas (FNS) can form anywhere along the course of the nerve, from the pontocerebellar angle to the terminal branches of the facial nerve. In this article, we propose a review of the specialized literature regarding the diagnostic and therapeutic management of schwannomas of the extracranial segment of the facial nerve, also presenting our experience in this type of rare neurogenic tumor...
