Glossopharyngeal and vagoglossopharyngeal neuralgia: Long-term surgical outcomes in a single institution.

Background: Glossopharyngeal neuralgia (GPN) and vagoglossopharyngeal neuralgia (VGPN) are infrequent syndromes that can have great negative impact on a patient's quality of life. The objective of this study is to describe the characteristics and long-term results of patients with GPN-VGPN who are treated surgically with microvascular decompression (MVD) in one institution. Methods: This is a retrospective series of 20 patients with the diagnosis of GPN-VGPN who underwent MVD. Demographic characteristics, surgical results, complications, and long-term follow-up were analyzed. Results: The mean age of symptom onset was 51.25 years and the majority of patients were women (60%). The posterior inferior cerebellar artery was the main offending vessel (75%). The immediate MVD success rate was 100%, but during follow-up, two patients (10%) were diagnosed with VGPN and both cases presented pain recurrence. The mean follow-up was 120.4 (25-333) months. VGPN (P = 0.005) and a ≥5 day hospital stay (P = 0.032) were associated with unsuccessful outcomes. Two complications were documented, which resolved without sequelae. There was no surgical mortality. Conclusion: MVD is an effective and safe treatment for long-term pain relief of GPN-VGPN. VGPN and a prolonged hospital stay were associated with poor outcomes. More studies are required to confirm these findings.

Actualización sobre el síndrome de Eagle y sus complicaciones neurocardiológicas: casos clínicos / An update on Eagle´s syndrome and its neuro-cardiological complications: clinical cases

El síndrome de Eagle o síndrome estilohioideo o sín-drome de la arteria carótida es un trastorno que se origina por la mineralización y elongación del pro-ceso estiloides. Factores traumáticos agudos y cró-nicos, así como otras teorías, han sido propuestos para explicar la etiología y patogenia de esta altera-ción. El conjunto de síntomas puede incluir: dolor fa-ríngeo, odinofagia, disfagia, cefalea, con irradiación a oreja y zona cervical. Si bien existen varias clasifi-caciones, de manera universal se acepta que existen principalmente dos formas de presentación de esta patología: el tipo I o clásico, generalmente asociado a un trauma faríngeo y acompañado de dolor en la zona faríngea y cervical, y el tipo II o carotídeo, que sue-le presentar molestia cervical, cefalea y alteración de la presión arterial, con riesgo de daño de la ac-tividad cardíaca. La identificación de este síndrome suele ser confusa dada la similitud de los síntomas con otras afecciones. El diagnóstico debe realizarse en base a los síntomas y a los estudios por imágenes específicos. El tratamiento puede ser conservador y actuar simplemente sobre los síntomas, o bien, qui-rúrgico. El objetivo del presente trabajo es realizar una revisión actualizada de la literatura sobre el sín-drome de Eagle y presentar tres casos clínicos con distintas manifestaciones (AU)

Eagle's syndrome or styloid syndrome or stylo-carotid artery syndrome is a disease caused by mineralization and elongation of the styloid process. Acute and chronic traumatic factors, along with other hypothesis, have been proposed to explain the aetiology and pathogenesis of this condition. Symptoms can include: pharynx pain, odynophagia, dysphagia, headache, with radiating pain to the ear and neck. Despite there are several classifications, it is universally accepted that this pathology can present in two forms: the type I or classic, generally associated to tonsillar trauma and characterized by pharyngeal and neck pain, and the type II or carotid artery type, which frequently presents with neck pain, headache, blood pressure variation, with risk of damage to cardiac function. Identifying of Eagle's syndrome is often confusing because some symptoms are shared with other pathologies. Diagnosis must be made on the basis of symptoms and imaging studies. Treatment can be conservative, acting only on symptoms, or surgical. The aim of this paper is to provide an updated review of the literature on Eagle syndrome and to present three clinical cases with different manifestations (AU)

Neuralgia del Trigémino, del Glosofaríngeo y Post-herpética en Pacientes del Hospital Universitario San Ignacio (HUSI) Bogota, Colombia / Trigeminal, Glossopharyngeal and Post-Herpetic Neuralgia in Patients of the San Ignacio University Hospital (HUSI) Bogota, Colombia

Determinar las características clínicas, pautas para el diagnóstico, tratamiento y evolución de la neuralgia del trigémino, postherpética y del nervio glosofaríngeo. Se realizó un estudio descriptivo de 119 historias clínicas de pacientes diagnosticados con neuralgia del trigémino, glosofaríngeo y postherpética tratados en el Hospital Universitario San Ignacio, registrando datos de sexo, edad, antecedentes médicos, exámenes complementarios, características clínicas, tratamientos y evolución. Se revisaron 119 historias clínicas, de las cuales 86 pertenecían a mujeres y 33 a hombres, el 84 % correspondían a neuralgias del trigémino, el 11,7 º% a post- herpética, y el 2,5% en el glosofaríngeo. El lado afectado más común fue el lado izquierdo con un 54%, las ramas más afectadas en la neuralgia del trigémino fue la maxilar y mandibular (V2- V3), en la postherpética la oftálmica (V1), la patología concomitante más frecuente hallada en el grupo fue la HTA, el tipo de dolor más frecuente fue el lancinante con un 82,4%. Los medicamentos más utilizados fueron la carbamazepina (60,5%) seguida de pregabalina (29,4%), en tratamientos quirúrgicos la radiofrecuencia fue la más empleada en un 32 %. 30 pacientes presentaron recaídas que en general fueron manejadas con aumento de las dosis de los medicamentos. Este estudio muestra una similitud con la literatura reportada, presentando más casos de neuralgia de trigémino, seguida de la post herpética y por último del glosofaríngeo. Más frecuente en mujeres, con un promedio de edad de 60 años, afectando en mayor proporción la rama mandibular y maxilar en la neuralgia de trigémino y en la postherpética la oftálmica.

To determine the clinical characteristics, guidelines for the diagnosis, treatment and evolution of trigeminal neuralgia, postherpetic neuralgia and glossopharyngeal neu- ralgia. A descriptive study of 119 clinical histories of patients diagnosed with Trigeminal Neoplasia, glossopharyngeal and postherpetic treated at the Hospital Universitario San Ignacio, recording data such as: gender, age, medical history, diagnostic exams, clinical features, branches and side of the face affected, treatments and evolution. 86 clinical records of women and 33 of men were evaluated, 100 with trigeminal neuralgia, 14 postherpetic, 3 glossopharyngeal, the most common affected side was the left side with 51%, the most affected branches in trigeminal neuralgia was the V2-V3, postherpetic V1, the most frequent antecedent of the neuralgias was the AHT, the type of pain that was more frequent was the lancinanting with 82.4%. The most commonly used medication was carbamazepine (60.5%) and pregabalin (29.4%); in surgical treatments radiofrequency was the most used in 32%; 30 patients had relapses that were generally managed with increased doses. This study shows a similarity with the reported literature, presenting more cases of trigeminal neuralgia, followed by the herpetic and finally the glossopharyngeal neuralgia, finding more cases in women than in men, with an average age of 60 years, affecting in Greater proportion the mandibular and maxillary branch in the trigeminal neuralgia and in the postherpetic ophthalmic.

Pediatric glossopharyngeal neuralgia: a comprehensive review.

INTRODUCTION: Debilitating facial pain can seriously affect an individual's daily living. Given that the pathophysiology behind neuropathic and myofascial pain is not fully understood, when chronic facial pain goes undiagnosed, it has been proposed that one of the two is the likely cause. Since their discovery, glossopharyngeal neuralgia (GN) and Eagle's syndrome have been considered mostly conditions afflicting the adult population. However, when pediatric patients present with symptoms resembling GN or Eagle's syndrome, physicians are less apt to include these as a differential diagnosis simply due to the low prevalence and incidence in the pediatric population. MATERIALS AND METHODS: A literature review was performed with the aim to better understand the history of reported cases and to provide a comprehensive report of the anatomical variations that lead to these two conditions as well as the way these variations dictated medical and surgical management. Articles were obtained through Google Scholar and PubMed. Search criteria included key phrases such as pediatric glossopharyngeal neuralgia and pediatric Eagle syndrome. These key phrases were searched independently. PubMed was searched primarily then cross-referenced articles were found via Google Scholar. Results from non-English articles were excluded. RESULTS: A total of 58 articles were reviewed. Most of the articles focused on adult glossopharyngeal neuralgia, and the majority was comprised of case reports. When searched via PubMed, a total of 16 articles and 2 articles returned for glossopharyngeal neuralgia and Eagle's syndrome, respectively. After criteria selection and cross-referencing, a total of seven articles were found with respect to pediatric glossopharyngeal neuralgia. CONCLUSIONS: While they are rare conditions, there are multiple etiologies that lead to the debilitating symptoms of GN and Eagle's syndrome. The clinical anatomy proved notable as multiple causes of GN and Eagle's syndrome are due to variation in the anatomy of the neurovascular structures surrounding the glossopharyngeal nerve, an elongated styloid process, a calcified stylohyoid ligament as well as a calcified stylomandibular ligament. Due to the success of different treatment modalities, the treatment of choice is dependent on clinical judgment.

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.(AU)

Glossopharyngeal neuralgia with syncope as a sign of neck cancer recurrence

Glossopharyngeal neuralgia with syncope as a sign of neck cancer is a very rare condition. A review of the literature revealed only 29 cases formerly reported. We present the first Brazilian case of such association. A 68-year-old man presented with paroxysmal excruciating pain over the right side of the neck, sometimes followed by syncope. Given the suspicion of recurrent tumor from a previously treated neck malignancy, a computed tomography scan was performed and a right parapharyngeal tumor was shown. Pain and syncope were successfully controlled with carbamazepine and the patient underwent palliative radiotherapy.

Neuralgia glossofaríngea com síncope como um sinal de câncer do pescoço é uma condição muito rara. Uma revisão da literatura revelou apenas 29 casos relatados anteriormente. Apresentamos o primeiro caso brasileiro de tal associação. Um homem de 68 anos se apresentou com dores paroxísticas insuportáveis no lado direito do pescoço, algumas vezes seguidas de síncope. Dada a suspeita de recidiva tumoral derivada de uma malignidade cervical tratada previamente, realizou-se um exame de tomografia computadorizada que evidenciou um tumor parafaríngeo direito. As dores e as síncopes foram controladas satisfatoriamente com carbamazepina e o paciente foi submetido à radioterapia paliativa.
