Descompresión microvascular para el manejo de la neuralgia del trigemino: presentación de caso clínico y revisión de la literatura / Microvascular decompression for the handling of trigeminal neuralgia: clinical case report and literature review

La neuralgia del trigémino es un trastorno neuropático paroxístico que afecta a una o varias de las ramas sensoriales del nervio trigémino cuya etiología es variada, la más aceptada es por compresiones vasculares a nivel del ángulo ponto cerebeloso que generan conflicto de espacio. Dentro de las posibilidades de tratamiento, la descompresión microvascular permite la cura fisiopatológica de la neuralgia del trigémino, teniendo resultados satisfactorios a corto/largo plazo, y bastantes ventajas en comparación a otras técnicas de mínima invasión. Se presenta el caso de una paciente con tratamiento médico máximo no efectivo, a la cual se realizó descompresión microvascular evidenciando conflicto arterial y venoso con el nervio.

Trigeminal neuralgia is a paroxysmal neuropathic disorder that affects one or more of the sensory branches of the trigeminal nerve, the etiology of which is varied, the most accepted being due to vascular compressions at the level of the brainstem that generate conflict of space. Within the treatment possibilities, microvascular decompression allows the pathophysiological cure of trigeminal neuralgia, having satisfactory results in the short / long term, and many advantages compared to other minimally invasive techniques. We present the case of a patient with maximum ineffective medical treatment, who underwent microvascular decompression, showing arterial and venous conflict with the nerve.

Los accesos al ángulo pontocerebeloso, a la región petro-clival y al cavum de Meckel son un verdadero desafío mi-croquirúrgico. El tubérculo suprameatal (TSM) es una prominencia ósea localizada por arriba del conducto audi-tivo interno. En algunos casos, donde es prominente, puede obstaculizar la visión completa del nervio trigémino en su segmento cisternal y su ingreso al cavum. En determinados casos para descompresión neurovascular en neuralgia trige-minal es necesario fresar el TSM para exponer la zona de contacto vasculonerviosa

Nervios olfatorio, trigémino, facial, glosofaríngeo y vago: vínculos con sars-cov-2 y prospectivas neurosemiológicas / Olfactory, trigeminal, facial, glossopharyngeal and vagus nerves: links with sars-cov-2 and neurosemiological prospects

Se presenta una breve revisión los nervios olfatorio, trigémino, facial, glosofaríngeo y vago, el primero funcionalmente relacionado con la inervación quimiosensitiva olfativa en la mucosa nasal, los siguientes para el registro de dolor endocraneal y para la mucosa orofaríngea, a efectos de transducción sensitiva gustativa. Estos nervios se vinculan con los síntomas en pacientes positivos para Covid-19, que manifiestan como dolor de cabeza, disosmia, anosmia, disgeusia, ageusia entre otras características neurosemiológicas. Se concluye que estas características semiológicas se puedan deber a mecanismos neurotrópicos y transinápticos por lo que se debe realizar un examen neurológico más riguroso sobre síntomas y signos de pacientes con Covid-19.

A brief review of olfactory, facial, glossopharyngeal and vagus nerves is presented, the first one functionally related to odoriferous chemosensory innervation in the nasal mucosa, the following four cranial nerves to endocranial headache and oropharyngeal mucosa for purposes of gustatory sensory transduction. These nerves are associated with symptoms in Covid-19 positive patients, which dysosmia, anosmia, dysgeusia, ageusia manifestation, among other neurosemiological characteristics. It is concluded that these semiological characteristics may be due to neurotropic and transynaptic mechanisms, therefore a more rigorous neurological examination should be performed on symptoms and signs of Covid-19 patients.

Background: Trigeminocardiac reflex is a sudden parasympathetic physiological response causing significant cardiovascular disturbances during nerve stimulation in the path of the fifth cranial nerve, generally during surgical procedures in oral and maxillofacial surgery, neurosurgery, ophthalmology, and dermatology. Arthroscopy of the temporomandibular joint has traditionally been considered a safe, minimally invasive surgical procedure, yet this technique is not without neuro and cardiovascular complications. Objective: To present a clinical case that during an arthroscopy of the temporomandibular joint in the instrumentation phase of the superior joint space, and under continuous monitoring by the anesthetist, report sudden bradycardia Conclusion: The intraoperative diagnosis of trigeminocardiac reflex was described by the anesthesiology service, receiving early pharmacological treatment of this condition, allowing an adequate trans and postoperative evolution.

Síndrome da fissura orbital superior associada a traumatismos craniomaxilofaciais / Superior orbital fissure syndrome associated with craniomaxillofacial traumatism

Introdução: A Síndrome da Fissura Orbital Superior (SFOS) é uma condição de ocorrência rara, inicialmente descrita por Hirchfield em 1858. Caracterizada pela presença de oftalmoplegia, ptose da pálpebra superior e midríase, podendo ocorrer parestesia da pálpebra superior e da região frontal, associada à lesão dos pares de nervos cranianos: oculomotor, troclear, abducente (III, IV e VI) e, por vezes, o nervo trigêmeo (V). A identificação da SFOS é importante, visto que sua incidência é rara no trauma, e sua identificação pode ajudar a direcionar o tratamento de forma mais adequada. Relato de caso: O presente trabalho descreve dois casos da SFOS associados a traumas craniofaciais, cita as possíveis etiologias relacionadas a essa síndrome e descreve a situação de trauma agudo. Considerações Finais: A avaliação das condições sistêmicas do paciente e de exames complementares, como tomografias computadorizadas, auxilia o diagnóstico diferencial entre patologias que acometem a região orbital e a base de crânio, fraturas e traumas craniofaciais. A identificação da SFOS no trauma agudo orienta a abordagem imediata ou precoce quando indicada, como nos casos de hematomas retrobulbares ou em grandes deslocamentos ósseos maxilofaciais com necessidade de redução cirúrgica. Nos casos com indicação de abordagem tardia, as fraturas craniofaciais são tratadas de forma conservadora, e o paciente é encaminhado para atendimento especializado... (AU)

Introduction: The superior orbital fissure syndrome (SOFS) is a rare condition and initially described by Hirchfield in 1858. Characterized by the presence of ophthalmoplegia, upper eyelid ptosis and mydriasis, and there may be paresthesia of the upper eyelid and forehead associated by the injury of the cranial nerves like: oculomotor, trochlear, abducens (III, IV and VI) and sometimes the trigeminal nerve (V). The identification of SOFS is important, since its incidence is rare in trauma, and its identification may help to target the treatment more adequately. Case report: The present study describes two cases of SFOS associated with craniofacial trauma, cites the possible etiologies related to this syndrome and describes the situation of acute trauma. Final considerations: The evaluation of the patient's systemic conditions and complementary exams, such as computed tomography, help the differential diagnosis between pathologies that affect the orbital region and the skull base, and fractures and traumatic head injuries. The identification of SFOS in acute trauma guides the immediate or early approach when indicated, as in cases of retrobulbar hematomas or large maxillofacial bone dislocations requiring surgical reduction. In cases with indication for late approach, craniofacial fractures are treated conservatively and the patient is referred for specialized care... (AU)

Role of neuron and non-neuronal cell communication in persistent orofacial pain

It is well known that trigeminal nerve injury causes hyperexcitability in trigeminal ganglion neurons, which become sensitized. Long after trigeminal nerve damage, trigeminal spinal subnucleus caudalis and upper cervical spinal cord (C1/C2) nociceptive neurons become hyperactive and are sensitized, resulting in persistent orofacial pain. Communication between neurons and non-neuronal cells is believed to be involved in these mechanisms. In this article, the authors highlight several lines of evidence that neuron-glial cell and neuron macrophage communication have essential roles in persistent orofacial pain mechanisms associated with trigeminal nerve injury and/or orofacial inflammation.

Management and prevention of third molar surgery-related trigeminal nerve injury: time for a rethink

Trigeminal nerve injury as a consequence of lower third molar surgery is a notorious complication and may affect the patient in long term. Inferior alveolar nerve (IAN) and lingual nerve (LN) injury result in different degree of neurosensory deficit and also other neurological symptoms. The long term effects may include persistent sensory loss, chronic pain and depression. It is crucial to understand the pathophysiology of the nerve injury from lower third molar surgery. Surgery remains the most promising treatment in moderate-to-severe nerve injuries. There are limitations in the current treatment methods and full recovery is not commonly achievable. It is better to prevent nerve injury than to treat with unpredictable results. Coronectomy has been proved to be effective in reducing IAN injury and carries minimal long-term morbidity. New technologies, like the roles of erythropoietin and stem cell therapy, are being investigated for neuroprotection and neural regeneration. Breakthroughs in basic and translational research are required to improve the clinical outcomes of the current treatment modalities of third molar surgery-related nerve injury.

Gamma Knife Radiosurgery in Recurrent Trigeminal Neuralgia after Other Procedures / 고신대학교의과대학학술지

OBJECTIVES: Trigeminal neuralgia (TN) is undurable paroxysmal pain in the distribution of the fifth cranial nerve. Invasive treatment modalities for TN include microvascular decompression (MVD) and percutaneous procedures, such as, radiofrequency rhizotomy (RFR). Gamma Knife radiosurgery (GKRS) is a considerable option for patients with pain recurrence after an initial procedure. This study was undertaken to analyze the effects of gamma knife radiosurgery in recurrent TN after other procedures. METHODS: Eleven recurrent TN patients after other procedures underwent GKRS in our hospital from September 2004 to August 2016. Seven patients had previously undergone MVD alone, two underwent MVD with partial sensory rhizotomy (PSR), and two underwent RFR. Mean patient age was 60.5 years. We retrospectively analyzed patient's characteristics, clinical results, sites, and divisions of pain. Outcomes were evaluated using the Visual Analog Scales (VAS) score. RESULTS: Right sides were more prevalent than left sides (7:4). The most common distribution of pain was V1 + V2 division (n = 5) following V2 + V3 (n = 3), V2 (n = 2), and V1 + V2 + V3 (n = 1) division. Median GKRS dose was 80 Gy and the mean interval between the prior treatment and GKRS was 74.45 months. The final outcomes of subsequent GKRS were satisfactory in most cases, and at 12 months postoperatively ten patients (90.0%) had a VAS score of ≤ 3. CONCLUSIONS: In this study, the clinical result of GKRS was satisfactory. Invasive procedures, such as, MVD, RFR are initially effective in TN patients, but GKRS provides a safe and satisfactory treatment modality for those who recurred after prior invasive treatments.

Trigeminal Neuralgia Resulting from Delayed Cervical Cord Compression after Acute Traumatic Fracture of Odontoid Process / 대한신경손상학회지

Trigeminal neuralgia is caused by compression of trigeminal nerve root and it leads to demyelination gradually. It was almost idiopathic and occurred unexpected. The upper cervical spinal cord contains the spinal trigeminal tract and nucleus. Fibers with cell bodies in the trigeminal ganglion enter in the upper pons and descend caudally to C2 level. We experienced a rare patient with facial pain, which was paroxysmal attack with severe pain after a clear event, cervical spinal injury (C2). So, this case reminds us of a possible cause of trigeminal neuralgia after a trauma of the head and neck.

Facial Herpes Zoster: A 15-year Retrospective Single-Center Study / 대한피부과학회지

BACKGROUND: Many studies about herpes zoster exist in the Korean dermatologic literature. However, few studies have reported about facial herpes zoster and its complications. OBJECTIVE: The purpose of this study was to investigate the epidemiology, clinical features, and complications of facial herpes zoster. METHODS: We analyzed the medical records of 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized patients into 8 groups based on the dermatomal distribution of herpetic lesions. We investigated the correlations between clinical features, prognosis, and complications. RESULTS: We analyzed the medical records of 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized patients into 8 groups based on the dermatomal distribution of herpetic lesions. We investigated the correlations between clinical features, prognosis, and complications. Results: The most common site of involvement of facial herpes zoster was the ophthalmic branch of the trigeminal nerve (59.2%). Herpes zoster involving the ophthalmic and the maxillary branches of the trigeminal nerves showed a significantly higher incidence rate of herpes zoster ophthalmicus than that observed with herpes zoster involving only the ophthalmic branch (odds ratio 7.373). Age and periorbital swelling were significantly correlated with herpes zoster ophthalmicus (p<0.001). Facial palsy was significantly correlated with otalgia and cutaneous ear involvement (p<0.001). Postherpetic neuralgia (PHN) occurred in 41% of patients with facial herpes zoster. Patients who received antiviral treatment within 3 days showed lower rates of PHN (35.8%) than patients who received treatment after 4 days (45.4%) (p=0.002). CONCLUSION: Facial herpes zoster is associated with several neurological complications. Variables including age, periorbital swelling, otalgia, and cutaneous ear involvement are useful predictors of complications and prognosis. Early institution of antiviral treatment and appropriate interdepartmental consultations are required for better treatment outcomes.

Trigeminocardiac reflex: sudden severe bradycardia during open reduction for temporomandibular joint dislocation: A case report

BACKGROUND: The trigeminocardiac reflex (TCR), which occurs after stimulation of the territory of the trigeminal nerve, is very rarely reported to be caused by stimulation of the mandibular branch. We report a case of TCR in open reduction for temporomandibular joint (TMJ) dislocation. CASE: A 74-year-old female presented for TMJ dislocation. During open reduction of TMJ under general anesthesia, severe bradycardia (15 beats/min) occurred. Immediately 0.5 mg atropine was administered intravenously, and the surgical manipulation was stopped. After 30 seconds, heart rate normalized. During surgery, severe bradycardia occurred one more time. It disappeared spontaneously as soon as surgical manipulation was stopped. The surgery was completed uneventfully. CONCLUSIONS: Because of the possibility of profound bradycardia, asystole, or even death when evoked, it is important to be aware of the trigeminocardiac reflex during manipulation of the mandibular divisions, especially during surgical stimulation of the TMJ.

An anatomical study of the lingual nerve in the lower third molar area / 대한해부학회지

The lingual nerve (LN) is a branch of the mandibular division of the trigeminal nerve, and its injury is one of the major complications during oral surgery. This study aims to investigate the anatomy of the LN in the lower third molar area. Twenty sides from ten fresh-frozen adult cadaveric Caucasian heads were examined to measure the diameter of the LN. The mean diameter of the LN was 2.20±0.37 mm (range, 1.61–2.95 mm). There were no statistically significant differences in the measurements between sexes, sides, or tooth status (dentulous or edentulous). Understanding the anatomical features of the LN is essential for performing any surgical procedure in the oral region.

The effects of cataract surgery on autonomic heart rate control: a prospective cross-sectional and analytical study

OBJECTIVES: We aimed to evaluate the effects of cataract surgery on cardiac autonomic modulation. METHODS: A cross-sectional and analytical study was conducted at the Hospital Maria Braido in the city of São Caetano do Sul, São Paulo, between 2015 and 2016. We investigated 19 patients of both sexes who were all over 50 years old; all patients had a diagnosis of senile or bilateral cataracts and were recommended to undergo implantation of the intraocular lens. Heart rate variability (HRV) was evaluated before, during and after cataract surgery. RESULTS: There were no significant changes in the time and geometric domains of HRV before, during or after surgery. The high-frequency (HF) band in normalized units (nu) on the spectral analysis significantly increased (p=0.02, Cohen's d=0.9, large effect size). However, the low-frequency (LF) band in nu significantly decreased during surgery (p=0.02, Cohen's d=0.9, large effect size). CONCLUSION: Throughout the intraocular lens implantation cataract surgery, there was an increase in parasympathetic modulation and a decrease in the sympathetic component of the heart rate (HR). We propose that this result is attributable to the supine position of the patients during surgery and the trigeminal reflex.

Atypical Cavernous Hemangioma of the Trigeminal Nerve:Report of One Case / 中国医学科学院学报

Trigeminal Cave Brain Metastasis from Prostate Adenocarcinoma: Case Report and Review of the Literature

The present study presents the case of a 66-year-old patient diagnosed with prostate adenocarcinoma 4 years earlier and treated with prostatectomy, radiotherapy, chemotherapy and hormonetherapy but still displaying high prostate-specific antigen (PSA) levels. The patient complaints were double vision and headaches. Upon physical examination, he displayed 6th cranial nerve paresis and 5th cranial nerve paresthesia. Amagnetic resonance imaging (MRI) exam was performed, which revealed a mass on the right trigeminal cave. The patient underwent surgical removal of the tumor, and the pathological analysis of the specimen established metastatic prostate cancer as the diagnosis. Brainmetastases fromprostate cancer are extremely rare and mark advanced disease, with immune system failure and blood-brain barrier breach. Prostate-specific antigen levels do not correlate with the possibility of metastatic disease. Prostate adenocarcinoma is the histologic typemost commonly associated with brainmetastases,with themeninges being more frequently affected, followed by the brain parenchyma. The neurological symptoms more often displayed are non-focal, such as headaches and mental confusion. Surgery associated with radiotherapy is the most validated treatment.

Neurinomas del Trigemino: resección con abordaje endonasal transeptoesfenoidal convencional / Trigeminal neuromas: resection with a conventional transeptosphenoidal endonasal approach

Introducción: Los Neurinomas del nervio trigémino (NNT) son los segundos más comunes después de los neurinomas vestibulares, constituyendo cerca del 10% de los neurinomas intracraneales y menos del 0.5% de los tumores intracraneales. Los NNT pueden ocurrir en cualquier parte del curso del ganglio trigeminal y raíces del nervio trigémino. La mayor incidencia es entre los 30 y 40 años, siendo más frecuentemente en mujeres. Por sus características benignas el objetivo del manejo quirúrgico es con fines curativos, habiéndose propuesto diferentes técnicas quirúrgicas, lo que provoca que la elección de una en particular sea motivo de controversia. El propósito es presentar nuestra experiencia quirúrgica con abordaje endonasal transeptoesfenoidal convencional con el uso de espéculos asimétricos endoscópicamente asistidos en el manejo de NNT. Materiales y métodos: Se hizo el seguimiento de 3 pacientes diagnosticados con NNT en quienes se realizó resección por abordaje endonasal transeptoesfenoidal convencional (RETC), durante el periodo entre 2014 y 2015, en el Instituto Nacional de Cancerología, Bogotá D. C., Colombia. Se describen variables demográficas, clínicas, radiológicas y quirúrgicas. Resultados: Dos de ellos fueron hombres y una mujer, la edad media fue 48.3 años (32-60 a). El principal síntoma fue hipoestesia en hemicara. La localización en los 3 casos fue en la fosa craneal media y posterior derechas. Se realizó la resección quirúrgica siguiendo el abordaje propuesto, obteniendo buena visualización del tumor con resección total del tumor en 2 casos y subtotal en 1 caso, con resolución de sintomatología, menos complicaciones, menor estancia hospitalaria posoperatoria consecuente al abordaje menos invasivo respecto a otros tipos de abordaje, sin recidiva tumoral a 1 año de seguimiento. Conclusiones: Por medio de un abordaje endonasal transeptoesfenoidal convencional se proporciona una adecuada exposición de NNT, siendo posible resecarlos adecuadamente, por lo que este enfoque ofrece una excelente alternativa para el manejo de NNT con una baja morbimortalidad.

Introduction: Ten percent of intracranial neuromas and fewer than 0.5% of intracranial tumors are trigeminal nerve neuromas (TNN), which may occur anywhere along the course of the trigeminal nerve. They are most frequent in women between 30 and 40 years old. Since these tumors are characteristically benign tumors, the aim of surgical treatment is to be curative. Different surgical techniques have been described; however, which choice to employ remains controversial. This paper reports our surgical experience with the conventional trans-septosphenoidal endonasal approach, using endoscopically-assisted asymmetric specula, to resect TNN. Methods and materials: We reviewed three patients with a TNN who underwent tumor resection employing a conventional trans-septosphenoidal endonasal approach between 2014 and 2015 at the National Cancer Institute, Bogotá D.C., Colombia. Demographic, clinical, radiological, and surgical characteristics are described. Results: Two of our three patients were men and one a woman; the mean age was 48,3 (32- 60) years old. The main symptom was facial hypo-aesthesia. In all three patients, the tumor was located in the right mid and posterior cranial fossa. Surgical resection was performed with the proposed approach, obtaining good visualization of the tumor. Total tumor resection was achieved in two patients, and subtotal in one. We observed the complete resolution of symptoms, as well as fewer complications, and shorter postoperative hospital stays with our less-invasive approach relative to other more-invasive approaches described in the literature. No tumor recurrence was noted in the two patients who underwent total resection at one year of follow-up; the other patient remained asymptomatic. Conclusions: Utilizing a conventional trans-septosphenoidal endonasal approach, adequate exposure and resection of trigeminal nerve neuromas can be achieved. As such, this approach offers an excellent alternative to more-invasive techniques for managing TNN, being associated with low morbidity and mortality.
