The glossopharyngeal nerve (IX cranial nerve pair): anatomical considerations and neuralgia: literature review / O nervo glossofaringeo (IX par de nervo craniano): considerações anatômicas e neuralgia: revisão da literatura

The glossopharyngeal nerve (IX cranial nerve) is a mixed nerve, with both motor and sensory function. This relates to the tongue and pharynx. Glossopharyngeal neuralgia is a rare nervous neuropathy, with poristic, lancinating and paritary crises, usually unilateral. The aim of the study was to review the literature on glossopharyngeal neuralgia of the nerve (IX cranial nerve), highlighting the anatomical aspects of this nerve and the possible causes and complications of neuralgia as well as forms of treatment. A literature review was carried out in the international Pubmed database. The literature review included 72 articles from 2015 to 2021. The keywords used were: "anatomy of glossopharyngeal neuralgia". Of the 72 articles, 7 were used for this literature review. Uncommon as nervous/glossophingeal etiologies and pathologies are neurological abnormalities/neurovarises and pathologies are neurovascular/neurovariseal lesions. Pharmacological treatment approaches mentioned in the literature were therapy with antiepileptics and antidepressants such as carbamazepine and gabapentin; a microvascular decompression; and gamma knife radiosurgery(AU)

Neuralgia del nervio glosofaríngeo posamigdalectomía: reporte de dos casos / Post-tonsillectomy glossopharyngeal nerve neuralgia: report of two cases

Resumen La amigdalectomía es uno de los procedimientos quirúrgicos más frecuentes que realiza el otorrinolaringólogo. Dentro de las complicaciones posoperatorias, la neuralgia del nervio glosofaríngeo es extremadamente poco frecuente. En este artículo se presentan dos casos clínicos pediátricos con neuralgia del glosofaríngeo posamigdalectomía que fueron resueltos con tratamiento médico.

Abstract Tonsillectomy is one of the most common procedures done by the otolaryngologist. Among post-operative complications, the glossopharyngeal neuralgia is extremely uncommon. This article presents two pediatric clinical cases with post-tonsillectomy glossopharyngeal neuralgia that were resolved with medical treatment.

"Ortoglossopelveplastia" e o algoritmo de sua utilização na sequência de Pierre-Robin / "Orthoglossopelveplasty" and the algorithm for its use in the Pierre Robin sequence

Introdução: Muitos pacientes portadores de sequência de Pierre Robin (micrognatia, glossoptose e obstrução de via aérea) apresentam o músculo genioglosso alterado, encurtado e retrátil, que impede a protração lingual, mantendo a parte anterior da língua verticalizada e seu volume deslocado em direção posterior. Isso pode corroborar para obstrução supraglótica, dificuldade alimentar e inversão das forças de estímulo do crescimento do corpo mandibular. Métodos: Estudo retrospectivo de pacientes com Pierre Robin tratados entre 2012 e 2017 pela equipe, com descrição da "ortoglossopelveplastia", que propõe uma modificação na glossopexia, soltando o genioglosso anômalo da sua inserção, liberando a língua para elevar seu terço anterior e avançar o volume de sua base, sendo auxiliada por ponto de tração da base lingual à sínfise mandibular. Apresentamos um algoritmo de tratamento proposto que prioriza a necessidade desta cirurgia, associada ou não à distração mandibular, de acordo com a gravidade da dificuldade respiratória e/ou alimentar. Resultados: São apresentados 12 casos de obstrução da orofaringe atendidos de 2012 a 2017, discutem-se suas prioridades, a ortoglossopelveplastia e se aplica o algoritmo proposto. Conclusão: A reorganização anatômica da musculatura em uma posição anteriorizada correta proporciona protração e funcionalidade à língua, com desobstrução da via aérea na orofaringe, melhora da função alimentar e do desenvolvimento mandibular, com baixa morbidade cirúrgica e poucas complicações.

Introduction: Several patients with the Pierre Robin sequence (micrognathia, glossoptosis, and airway obstruction) have an altered, shortened, and retractable genioglossus muscle that prevents protraction of the tongue and keeps the anterior part of the tongue vertical and its volume posteriorly displaced. This can contribute to supraglottic obstruction, feeding difficulty, and inversion of the growth stimulation forces of the mandibular body. Methods: A retrospective study of patients with the Pierre Robin sequence treated between 2012 and 2017 with "orthoglossopelveplasty," which includes modification of glossopexy, releasing the anomalous genioglossus of its insertion and releasing the tongue to raise its anterior third and advance the volume of its base using a traction suture of the tongue base to the mandible symphysis. We present a treatment algorithm that prioritizes the need for surgery associated, or not, with mandibular distraction in accordance with respiratory and/or feeding difficulty severity. Results: Twelve cases of oropharyngeal obstruction treated from 2012 to 2017 are presented, their priorities and orthoglossopleoplasty are discussed, and the proposed algorithm is applied. Conclusion: Anatomical reorganization of the musculature in a correct anterior position provides protraction and functionality to the tongue, clears the airway in the oropharynx, and improves the feeding function and mandibular development, with low surgical morbidity rates and few complications.

Revisión morfológica, clínica y quirúrgica sobre el nervio glosofaríngeo / Morphological, clinical and surgical review on the glosopharyngeal nerve

En 1910, Weisenberg describió por primera vez la neuralgia del nervio glosofaríngeo (NGF), en un joven con diagnóstico de neuralgia del trigémino y sometido a múltiples intervenciones quirúrigcas, llegando a la sección del ganglio del trigémino. Algunas investigaciones han abordado la relación entre el nervio glosofaríngeo y las estructuras circundantes, desde su origen en el tronco encefálico y su trayecto a través de la base de cráneo. La examinación imagenológica de la interface entre la base de cráneo y los tejidos blandos de la región es compleja, ya que esas estructuras en la base del cráneo presentan características radiológicas de gran penetrancia y además pueden ser fácilmente dañadas o alteradas durante la disección anatómica o la cirugía. Si bien la NGF es un sindrome facial infrecuente, constituye una enfermedad neurológica de importancia por el gran sufrimiento que ocasiona, y en algunos casos, por los serios problemas que pueden amenazar la vida del paciente, debido a la posibilidad de aparición de sincopes y arritmias cardíacas. El objetivo de este trabajo consiste en realizar una revisión biobliográfica de la morfología del nervio glosofaríngeo, sus relaciones vasculares, y la importancia de su conocimiento en la clínica y la cirugía.

In 1910, Weisenberg first described nephropathy of the glossopharyngeal nerve (NGF) in a young man diagnosed with trigeminal neuralgia and undergoing multiple surgical interventions, reaching the trigeminal ganglion section. Some research has addressed the relationship between the glossopharyngeal nerve and the surrounding structures, from its origin in the brainstem and its path through the skull base. Imaging of the interface between the skull base and the soft tissues of the region is complex, since these structures at the base of the skull exhibit radiological characteristics of great penetrance and can be easily damaged or altered during anatomical dissection or surgery. Although NGF is an uncommon facial syndrome, it is a major neurological disease due to the great suffering it causes, and in some cases, serious problems that may threaten the patient's life, due to the possibility of syncopes and arrhythmias Cardiac disorders. The objective of this work is to perform a biobliographic review of the glossopharyngeal nerve morphology, its vascular relationships, and the importance of its knowledge in clinical and surgery.

Microvascular Decompression for Glossopharyngeal Neuralgia: Clinical Analyses of 30 Cases

OBJECTIVE: We present our experience of microvascular decompression (MVD) for glossopharyngeal neuralgia (GPN) and evaluate the postoperative outcomes in accordance with four different operative techniques during MVD. METHODS: In total, 30 patients with intractable primary typical GPN who underwent MVD without rhizotomy and were followed for more than 2 years were included in the analysis. Each MVD was performed using one of four different surgical techniques: interposition of Teflon pieces, transposition of offending vessels using Teflon pieces, transposition of offending vessels using a fibrin-glue-coated Teflon sling, and removal of offending veins. RESULTS: The posterior inferior cerebellar artery was responsible for neurovascular compression in 27 of 30 (90%) patients, either by itself or in combination with other vessels. The location of compression on the glossopharyngeal nerve varied; the root entry zone (REZ) only (63.3%) was most common, followed by both the REZ and distal portion (26.7%) and the distal portion alone (10.0%). In terms of detailed surgical techniques during MVD, the offending vessels were transposed in 24 (80%) patients, either using additional insulation, offered by Teflon pieces (15 patients), or using a fibrin glue-coated Teflon sling (9 patients). Simple insertion of Teflon pieces and removal of a small vein were also performed in five and one patient, respectively. During the 2 years following MVD, 29 of 30 (96.7%) patients were asymptomatic or experienced only occasional pain that did not require medication. Temporary hemodynamic instability occurred in two patients during MVD, and seven patients experienced transient postoperative complications. Neither persistent morbidity nor mortality was reported. CONCLUSION: This study demonstrates that MVD without rhizotomy is a safe and effective treatment option for GPN.

Lipoma Causing Glossopharyngeal Neuralgia: A Case Report and Review of Literature

The cerebello-pontine angle lipomas causing trigeminal neuralgia or hemifacial spasm are rare. A lipoma causing glossopharyngel neuralgia is also very rare. A 46-year-old woman complained of 2-year history of severe right throat pain, with ipsilateral episodic otalgic pain. The throat pain was described as an episodic lancinating character confined to the throat. Computed tomography and magnetic resonance imaging revealed a suspicious offending posterior inferior cerebellar artery (PICA) compressing lower cranial nerves including glossopharyngeal nerve. At surgery, a soft, yellowish mass (2x3x3 mm in size) was found incorporating the lateral aspect of proximal portion of 9th and 10th cranial nerves. Only microvascular decompression of the offending PICA was performed. Additional procedure was not performed. Her severe lancinating pain remained unchanged, immediate postoperatively. The neuralgic pain disappeared over a period of several weeks. In this particular patient with a fatty neurovascular lump causing glossopharyngeal neuralgia, microvascular decompression of offending vessel alone was enough to control the neuralgic pain.

Soporte respiratorio muscular para evitar el fallo respiratorio y la traqueotomía: ventilación no invasiva y técnicas de tos asistida / Respiratory muscle aids to prevent respiratory failure and tracheotomy: Noninvasive mechanical ventilation and mechanically assisted coughing

El propósito de este artículo es describir el uso de técnicas de soporte respiratorio muscular no invasivo con el fin de prevenir la insuficiencia respiratoria y el fallo ventilatorio, permitiendo la extubación y decanulación de pacientes considerados "imposibles de destetar''. La aplicación de presión en la vía aérea de forma no invasiva durante la inspiración puede proporcionar un soporte ventilatorio continuo en pacientes con poca o inexistente capacidad vital. Así mismo, podrá alcanzarse un pico flujo espiratorio efectivo en pacientes con una disfunción severa de los músculos espiratorios. En abril de 2010 un consenso clínico de 19 centros en 18 países describió 1623 pacientes neuromusculares con atrofia muscular espinal tipo 1, distrofia muscular de Duchenne (DMD) y esclerosis lateral amiotrófica que sobrevivieron utilizando soporte ventilatorio continuo sin necesidad de traqueotomía. De esta serie de pacientes, 76 (47%) precisaron ventilación no invasiva continua en un periodo de seguimiento de 15 años. De estos 76.22 (30.1%) de los enfermos fueron extubados y 35 (4.6%) decanulados en cuatro centros especializados. En estos centros se extuban rutinariamente pacientes con distrofia muscular de Duchenne considerados "imposibles de destetar", de forma que ninguno de sus más de 250 enfermos ha requerido traqueotomía. Esta aproximación en el tratamiento se está abriendo camino en varios centros de España, México y América45.

The purpose of this article is to describe the use of noninvasive inspiratory and expiratory muscle aids to prevent ventilatory insufficiency and failure, and to permit the extubation and tracheostomy tube decannulation in "unweanable" patients. Noninvasive airway pressure aids can provide a continuous support to respiratory ventilation for patients with little or no vital capacity and can provide effective cough flows in patients with severely dysfunctional expiratory muscles. In April 2010, a consensus of clinicians from 19 centers in 18 countries reported the experience of noninvasive ventilation in 1623 patients with spinal muscular atrophy type 1 (SMA1), Duchenne muscular dystrophy (DMD), and amyotrophic lateral sclerosis (ALS), who survived without tracheotomy. The survival was for more than 15 years in 76 patients. Among these 76 patients, 22 (30.1%) were extubated and 35 (4.6%) were decannulated in four specialized centers. In these centers, unweanable DMD patients are routinely extubated; none of over 250 such patients has undergone tracheotomy. This approach is now being introduced into different centers in Spain, Mexico and the United States.

Duration of remission phase of 36 Korean patients with glossopharyngeal neuralgia / 대한마취과학회지

BACKGROUND: Glossopharyngeal neuralgia has the characteristic of a long remission phase between the pain attack phases. Although the concept of remission is very important for the treatment of patients with glossopharyngeal neuralgia, due to the rarity of the disease, clear statistical studies on the remission phase for glossopharyngeal neuralgia are almost non-existent. METHODS: Previous chart reviews and phone interviews were conducted on a total of 38 patients. Among these study subjects, two patients were excluded because of their known secondary glossopharyngeal neuralgia from their brain tumors. Hence, the average duration of remission was investigated on 36 patients with idiopathic glossopharyngeal neuralgia. RESULTS: For the 27 patients who experienced their first remission, the average duration of the remission was 3.1 years. Among them, the average duration of the second remission of the 17 patients was 2.5 years, and for 4 patients who experienced a third remission, the average duration of the remission phase was 1.9 years. CONCLUSIONS: The difference in the mean duration of the remission phase of the 1st, 2nd, and 3rd are not statistically significant, and the occurrence rate of the left or right side and of the gender, male or female, are also statistically insignificant. However, it is possible to infer that a patient might face a pain attack phase when his or her remission phase has lapsed for about three years. This prediction may be applied when developing treatment plans for patients with glossopharyngeal neuralgia.

Permanent Pacemaker Implantation in a Patient with Cardiac Syncope Associated with Glossopharyngeal Neuralgia / 대한내과학회지

Glossopharyngeal neuralgia is a rare disease that is characterized by sharp pain in the posterior pharynx, tonsils, and larynx, triggered by swallowing. Glossopharyngeal neuralgia can trigger bradycardia or asystole, which can induce life-threatening cardiac syncope. A 55-year-old male was admitted with severe paroxysmal pain in his left jaw and ear, followed by asystole and syncope. We report a patient with cardiac syncope associated with glossopharyngeal neuralgia treated with a permanent pacemaker.

Glossopharyngeal Neuralgia Caused by Arachnoid Cyst in the Cerebellopontine Angle

Glossopharyngeal neuralgia is a relatively rare condition characterized by severe, paroxysmal episodes of lancinating pain in the tongue, throat, ear, and tonsil. This disorder is assumed to be due to compression of the glossopharyngeal nerve by vascular structures. A 47-year-old woman complaining of sharp and lancinating pain in the right periauricular and submandibular areas visited our hospital. Swallowing, chewing, and lying on her right side triggered the pain. Her neurologic examination revealed no specific abnormalities. The results of routine hematologic and blood chemistry studies were all within normal limits. Carbamazepine and gabapentin were given, but her symptoms persisted. Her pain was temporarily relieved only by narcotic pain medication. MRI showed an arachnoid cyst located in the right cerebellomedullary cistern extending to the cerebellopontine cistern. Cyst removal was performed via a right retrosigmoid approach. Lateral suboccipital craniotomy was performed using the right park-bench position. After opening the dura and cerebellopontine angle, the arachnoid cyst was exposed. The arachnoid cyst was compressing the flattened lower cranial nerves at the right jugular fossa. Her symptoms resolved postoperatively. Two months after the operation, she was completely free from her previous symptoms.

Severe Pain Attack Associated with Neurocardiogenic Syncope Induced by Glossopharyngeal Neuralgia: Successful Treatment with Carbamazepine and a Permanent Pacemaker: A Case Report

Glossopharyneal neuralgia (GPN) is generally considered to be a pain disease. However, it can be also be a life-threatening cardiac cause of syncope. Neuralgia in the throat and neck can trigger severe bradycardia up to the point of asystole, which can progress to cardiac syncope with or without seizures. A 65 year-old male patient diagnosed with glossopharyngeal neuralgia complained of severe paroxysmal pain in his right chin and ear followed by bradycardia, aystole and syncope. We report a case successfully treated with a permanent pacemaker and carbamazepine in a patient with GPN who had syncopal attacks preceded by paroxysms of pain.

Síndromes de compression neurovascular descompresión microvascular: nuestra experiencia (2003-2009) / Neurovascular compression syndroms microvascular decompression: our experience (2003-2009)

Objective. To present and evaluate the surgical results of microvascular decompression in the treatment of trigeminal neuralgia, glossopharyngeal neuralgia and hemifacial spasm. Material and Method. We present 15 patients with compressive syndrome of cranial nerve during a period of 6 years: 11 patients with trigeminal neuralgia, 2 patients with glossopharyngeal neuralgia and 2 patients with hemifacial spasm. Results. We achieved total improvement in 8 patients and partial in 4. The most frequent symptom after surgery was hypoesthesia in V2 in patients with trigeminal neuralgia. 3 patients presented temporary facial paresis. Conclusion. Microvascular decompression is an effective treatment with low morbidity in patients with compressive syndrome of cranial nerves. The goal of treatment should be complete disappearance of symptoms.

Neuralgía del glosofaríngeo: presentación de dos casos / Glosspharyngeal neuralgia: report of two cases

Objective. To present 2 cases of glossopharyngeal neuralgia treated by microvascular decompression. Description. Case one. 37-year- old male suffering pain in the posterior region of the left half of the tongue for 3 years. The diagnosis was left glossopharyngeal neuralgia. We performed microvascular decompression with Teflon felt. The patient has improved however he is still under medication. Case two. 59-year-old female suffering pain in the posterior third of the left half of the tongue. The diagnosis was left glossopharyngeal neuralgia. We performed microvascular decompression with Teflon. Symptoms completely disappeared. Conclusion. Glossopharyngeal neuralgia is infrequent. It can be treated with microvascular decompression with good results.

Combined Hyperactive Dysfunction Syndrome of the Cranial Nerves

OBJECTIVE: Combined hyperative dysfunction syndrome (HDS) defined as the combination of HDSs such as trigeminal neuralgia (TN), hemifacial spasm (HFS) and glossopharyngeal neuralgia (GPN), which may or may not occur simultaneously on one or both sides. We reviewed patients with combined HDS and demonstrated their demographic characteristics by comparing them with those of patients with a single HDS. METHODS: Between October 1994 and February 2006, we retrospectively studied a series of 1,720 patients who suffered from HDS and found 51 patients with combined HDSs. We analyzed several independent variables in order to evaluate the prevalence and etiologic factors of combined HDS. RESULTS: The combined HDS group accounted for 51 of 1,720 (2.97%) patients with HDS; 27 cases of bilateral HFS, 10 cases of bilateral TN and 14 cases of HFS with TN. Their mean age was 52.1 years (range, 26-79 years). There were 5 men and 46 women. Seven patients had synchronous and 44 patients metachronous onset of HDSs. By comparison of combined and single HDS groups, we found that age and hypertension were closely associated with the prevalence of combined HDS (p < 0.05). CONCLUSION: This study revealed that combined HDS was very rare. Hypertension and age might be the most important causative factors to evoke combined HDS.
