Parálisis facial alternobárica: a propósito de un caso y revisión de la literatura / Alternobaric facial palsy: case report and literature review

La parálisis o paresia facial alternobárica es una neuropraxia del séptimo nervio cra-neal debido a cambios de presión. Se produce en el contexto de una disfunción de la trompa de Eustaquio, una dehiscencia canal del nervio facial y cambios en la presión atmosférica. Se considera una rara complicación de barotrauma. Su prevalencia es difícil de estimar y, probablemente, se encuentre subreportada. La forma de presentación más habitual incluye paresia facial, plenitud aural, hipoacusia, otalgia, parestesias faciales y linguales. La mayoría de los episodios son transitorios, con una duración entre minutos y algunas horas, con recuperación posterior completa. Entre los diagnósticos diferenciales se encuentran causas periféricas y centrales de paresia facial, las cuales hay que sospechar ante la persistencia de los síntomas en el tiempo o ante la presencia de otros signos o síntomas neurológicos. La evaluación inicial debe incluir un examen otoneurológico completo. La tomografía computarizada de hueso temporal favorece la visualización de posibles dehiscencias del canal del facial. La prevención de nuevos episodios incluye la práctica de ecualización efectiva, la resolución de la disfunción de la trompa de Eustaquio y en algunos casos específicos, métodos alternativos de ventilación del oído medio como la colocación de tubos de ventilación. Una vez instalada la parálisis facial, si no se produce recuperación espontánea, el uso de corticoides es una opción. Se presenta un caso de paresia facial alternobárica recurrente y una revisión de literatura.

Alternobaric facial palsy or paralysis is a neuropraxia of the seventh cranial nerve due to pressure changes. It occurs in the context of Eustachian tube dysfunction, facial nerve canal dehiscence, and changes in atmospheric pressure. It is considered a rare complication of barotrauma. Its prevalence is difficult to estimated, and this condition is probably underreported. The most common form of presentation includes facial weakness, ear fullness or pressure, hearing loss, otalgia, facial and lingual paresthesias. Most episodes are transient, lasting from minutes to a few hours, with a subsequent complete recovery. Among the possible differential diagnoses are peripheral and central causes of facial paralysis, which must be suspected due to the persistence of symptoms over time or the presence of other neurological signs or symptoms. The initial evaluation should include a complete otoneurological examination. Computed tomography of the temporal bone is useful for the visualization of facial canal dehiscence. Prevention of further episodes includes practicing effective equalization, Eustachian tube dysfunction treatment, and in certain specific cases, alternative middle ear ventilation methods such as tympanostomy tubes. Once facial paralysis is established, if spontaneous recovery does not occur, the use of corticosteroids is considered an option. A case of recurrent alternobaric facial paresis and a review of the literature are presented.

Differential diagnosis and surgical management in chondrosarcoma of the jugular foramen / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the diagnosis, surgical management and outcome of jugular foramen chondrosarcoma (CSA). Methods: Fifteen patients with jugular foramen CSA hospitalized in the Department of Otorhinolaryngology Head and Neck Surgery of Chinese PLA General Hospital from December 2002 to February 2020 were retrospectively collected,of whom 2 were male and 13 were female, aging from 22 to 61 years old. The clinical symptoms and signs, imaging features, differential diagnosis, surgical approaches, function of facial nerve and cranial nerves IX to XII, and surgical outcomes were analyzed. Results: Patients with jugular foramen CSA mainly presented with facial paralysis, hearing loss, hoarseness, cough, tinnitus and local mass. Computed tomography (CT) and magnetic resonance (MR) could provide important information for diagnosis. CT showed irregular destruction on bone margin of the jugular foramen. MR demonstrated iso or hypointense on T1WI, hyperintense on T2WI and heterogeneous contrast-enhancement. Surgical approaches were chosen upon the sizes and scopes of the tumors. Inferior temporal fossa A approach was adopted in 12 cases, inferior temporal fossa B approach in 2 cases and mastoid combined parotid approach in 1 case. Five patients with facial nerve involved received great auricular nerve graft. The House Brackmann (H-B) grading scale was used to evaluate the facial nerve function. Preoperative facial nerve function ranked grade Ⅴ in 4 cases and grade Ⅵ in 1 case. Postoperative facial nerve function improved to grade Ⅲ in 2 cases and grade Ⅵ in 3 cases. Five patients presented with cranial nerves Ⅸ and Ⅹ palsies. Hoarseness and cough of 2 cases improved after operation, while the other 3 cases did not. All the patients were diagnosed CSA by histopathology and immunohistochemistry, with immunohistochemical staining showing vimentin and S-100 positive, but cytokeratin negative in tumor cells. All patients survived during 28 to 234 months' follow-up. Two patients suffered from tumor recurrence 7 years after surgery and received revision surgery. No complications such as cerebrospinal fluid leakage and intracranial infection occurred after operation. Conclusions: Jugular foramen CSA lacks characteristic symptoms or signs. Imaging is helpful to differential diagnosis. Surgery is the primary treatment of jugular foramen CSA. Patients with facial paralysis should receive surgery in time as to restore the facial nerve. Long-term follow-up is necessary after surgery in case of recurrence.

Application status and analysis of Fu's subcutaneous needling in the treatment of peripheral facial paralysis / 中国针灸

This paper summarizes the status of application and research of Fu's subcutaneous needling for peripheral facial paralysis, and the characteristics of different stages of peripheral facial paralysis treated with Fu's subcutaneous needling are analyzed from the aspects of intervention timing, protocol design, needle insertion point, sweeping and reperfusion activity, tube retaining time and acupuncture frequency. It is found that there are no norms and standards in sweeping and reperfusion, tube retention and acupuncture frequency in clinical application，and the exploration of staged treatment is insufficient in the research. In the future, it is necessary to form standardized operation to promote clinical promotion, and improve the research on treatment rules and mechanism according to the characteristics of disease stage.

Parálisis facial periférica bilateral postraumática / Bilateral post-traumatic facial palsy

La parálisis del VII par craneal o nervio facial, es una de las neuropatías más frecuentes. Sin embargo, la bilateral ocurre solo en el 0,3 a 2% de los casos. Se describe el caso de un paciente con parálisis facial periférica bilateral progresiva, secundaria a traumatismo craneoencefálico con fractura de ambos temporales, a quien se le realizó tratamiento médico con esteroides y fisioterapia con mejoría, por lo que se decidió expectar la conducta quirúrgica del nervio facial

Facial nerve palsy is one of the most common neuropathies. However, bilateral occurs only in 0.3 to 2% of cases. The case of a patient with progressive bilateral facial nerve palsy, secondary to cranioencephalic trauma with fracture of both temporal was treated with steroids and physiotherapy with subsequent resolution of symptoms, so it was decided dedicated wait for surgery

Directrices para el diagnóstico y tratamiento de Molares Retenidos / Guidelines for diagnosis and treatment of impacted molars

Los terceros molares son piezas dentarias correspondientes a la dentición permanente y se encuentran por detrás de los segundos molares. Erupcionan entre los 18 y 27 años aproximadamente, tienen variedad de formas, anomalías y disposición diversa. Normalmente se encuentran total o parcialmente retenidos en el hueso maxilar. La retención es muy frecuente y afecta aproximadamente al 75% de la población. La causa principal es por la falta de espacio dentro de la boca. La patología derivada de la retención de un tercer molar puede generar diferentes alteraciones: abscesos, sinusitis, reabsorción de las raíces de los dientes adyacentes, caries del molar retenido y/o del segundo molar, úlceras en la mucosa contigua, podrían generar quistes, ameloblastomas y ulceraciones leucoqueratósicas que pueden degenerar en carcinomas, alteraciones nerviosas o vasomotoras: dolores faciales, trismus, y parálisis facial ipsilateral. Las extracciones profilácticas de terceros molares asintomáticos están justificadas cuando los terceros molares se encuentran bajo prótesis removible que puede estimular su erupción, molares semierupcionados que pueden generar pericoronitis, caries o problemas periodontales; pacientes que van a ser sometidos a radioterapia; cuando el diente incluido interfiera en una cirugía ortognática. Si el molar retenido presenta sintomatología por parte del paciente está aconsejada su extracción quirúrgica.

The third molars are dental pieces corresponding to the permanent dentition and are located behind the second molars. They erupt between the ages of 18 and 27 approximately, have a variety of shapes, anomalies, and diverse dispositions. They are normally fully or partially retained in the maxillary bone. Retention is very frequent and affects approximately 75% of the population. The main cause is due to the lack of space inside the mouth. The pathology derived from the retention of a third molar can generate different alterations: abscesses, sinusitis, resorption of the roots of adjacent teeth, caries of the retained molar and/or second molar, ulcers in the contiguous mucosa, could generate cysts, ameloblastomas and leukokeratotic ulcerations that can degenerate into carcinomas, nervous or vasomotor disorders: facial pain, trismus, and ipsilateral facial paralysis. Prophylactic extractions of asymptomatic third molars are justified when the third molars are under removable prosthesis that can stimulate their eruption, semi-erupted molars that can generate pericoronitis, caries or periodontal problems; patients who are going to undergo radiotherapy; when the included tooth interferes with orthognathic surgery. If the retained molar presents symptoms on the part of the patient, its surgical extraction is recommended.

Parálisis facial aislada posterior a infección por virus de chikunguña: un nuevo diagnóstico diferencial / Isolated facial palsy after Chikungunya infection: A novel differential diagnosis

En las últimas décadas, se ha incrementado el reporte de manifestaciones neurológicas asociadas con la infección por el virus de chikunguña. Se informa el caso de un adulto joven previamente sano que presentó parálisis facial izquierda aislada después de una infección reciente por el virus de chikunguña en el trópico colombiano. Se describen aspectos importantes de la fisiopatología del virus y su tropismo por el sistema nervioso central y periférico, y se sugiere considerar este virus en el diagnóstico diferencial de la parálisis facial en pacientes con infección confirmada por el virus de chikunguña en regiones tropicales endémicas o en aquellos con antecedente de viajes recientes a dichas regiones.

A significant raise in the reports of neurological manifestations due to Chikungunya virus has been described worldwide. Here, we describe a case report of a previously healthy young adult who developed isolated left facial palsy after a confirmed Chikungunya virus infection in the Colombian tropics. We suggest considering this virus as a differential diagnosis for facial palsy in patients with confirmed Chikungunya virus infection who live in endemic regions or report a history of recent travel to these regions.

Autopercepção da paralisia facial e condições sociodemográficas clínicas de pacientes pós-AVC agudo: uma análise de associação / Self-perception of facial paralysis and sociodemographic-clinical conditions of postacute stroke patients: association analysis / Autopercepción de pacientes agudos faciales y condiciones sociodemográficas-clínicas posteriores post-accidente cerebrovascular en la fase aguda un análisis de asociación de pacientes

Introdução: A Paralisia Facial é uma das sequelas mais comuns em pacientes pós- Acidente Vascular Cerebral, podendo ocasionar uma série de consequências negativas para autopercepção. Objetivos: Avaliar autopercepção dos pacientes quanto à paralisia facial pós-Acidente Vascular Cerebral na fase aguda e verificar se está relacionada às condições sociodemográficas e clínicas. Método: Trata-se de estudo descritivo observacional com 86 pacientes com paralisia facial pós-Acidente Vascular Cerebral. Os critérios de inclusão foram idade acima de 18 anos, escala de Glasgow maior que 13 e compreensão preservada. Dados sócio-demográficos e clínicos foram extraídos do prontuário. A mímica facial foi avaliada com protocolo House & Brackmann (1985) e a autopercepção quanto aos incômodos físicos e psicossociais pelo questionário de auto-avaliação da condição facial. Foram realizadas análises descritiva e de associação com significância estatística de 5%. Resultados: O grau de comprometimento da paralisia facial variou entre moderado a paralisia total. A maioria dos pacientes avaliou a face em repouso como boa, movimento da face como péssima e ruim, sendo os lábios com pior classificação. Os pacientes relataram muito prejuízo nas atividades sociais, muita insatisfação com a face e médio prejuízo da alimentação. A análise de associação revelou que a autopercepção da face em repouso está associada ao sexo e ao comprometimento neurológico. Conclusão: Os pacientes na fase aguda do Acidente Vascular Cerebral possuem autopercepção de que a paralisia facial impacta no movimento dos lábios e atividades psicossociais, sendo pior para as mulheres e naqueles com o nível de comprometimento neurológico moderado e grave.

Introduction: Facial palsy is one of the most common sequelae in post-stroke patients, bringing a series of negative consequences for self-perception. Objective: To evaluate patients' self-perception regarding facial palsy after acute stroke and verify if it is related to sociodemographic and clinical conditions. Method: This is a descriptive observational study with 86 patients with facial paralysis after acute stroke admitted to a public hospital. The inclusion criteria were age over 18 years, Glasgow scale above 13 and preserved understanding. Socio-demographic and clinical data were extracted from the medical records. Facial mimicry was assessed using the House & Brackmann protocol (1985) and self-perception of physical and psychosocial discomfort using the facial condition self-assessment questionnaire. Descriptive and association analyses were performed with statistical significance of 5%. Results: The degree of impairment of facial paralysis varied from moderate to total paralysis. Most patients rated the resting face as good, face movement as very bad and bad, with the lips being the worst rated. The patients reported a lot of damage in social activities, a lot of dissatisfaction with the face and medium impairment on eating. The association analysis revealed that self-perception of the face at rest is associated with sex and neurological impairment. Conclusion: Patients in the acute phase of stroke have a self-perception that facial paralysis impacts on lip movement and psychosocial activities, being worse for women and those with moderate and severe neurological impairment.

Anatomical description of the extratemporal facial nerve under high-definition system: a microsurgical study in rats

Purpose: To describe the microsurgical anatomical aspects of the extratemporal facial nerve of Wistar rats under a high-definition video system. Methods: Ten male Wistar rats (12­15 weeks old), without veterinary diseases, weighing 220­280 g, were used in this study. All animals in this study were submitted to the same protocol and by the same surgeon. A 10-mm incision was made below the bony prominence of the right or left ear, and extended towards the angle of the mandible. The dissection was performed and the main branches of the facial nerve were dissected. Results: The main trunk of the facial nerve has a length of 0.88 ± 0.10 mm and a length of 3.81 ± 1.03 mm, measured from its emergence from the stylomastoid foramen to its bifurcation. Seven branches originating from the facial nerve were identified: posterior auricular, posterior cervical, cervical, mandibular, buccal, temporal, and zygomatic. Conclusions: The anatomy of the facial nerve is comparable to that of humans, with some variations. The most observed anatomical division was the distribution in posterior auricular, posterior cervical, cervical, mandibular, buccal, temporal, and zygomatic branches. There is no statistical difference between the thickness and distance of the structures compared to the contralateral side.

Late peripheral facial paralysis after COVID-19: a rapid systematic review and two case reports

Peripheral facial paralysis (PFP) has been shown to be a neurological manifestation of COVID-19. The current study presents two cases of PFP after COVID-19, along with a rapid review of known cases in the literature. Both case reports were conducted following CARE guidelines. We also performed a systematic review of PFP cases temporally related to COVID-19 using PubMed, Embase, and Cochrane Library databases on August 30, 2021, using a rapid review methodology. The two patients experienced PFP 102 and 110 days after COVID-19 symptom onset. SARS-CoV-2 RNA was detected in nasal samples through reverse-transcription real-time polymerase chain reaction (RT-qPCR) testing. Anosmia was the only other neurological manifestation. PFP was treated with steroids in both cases, with complete subsequent recovery. In the rapid review, we identified 764 articles and included 43 studies. From those, 128 patients with PFP were analyzed, of whom 42.1% (54/128) were male, 39.06% (50/128) female, and in 23 cases the gender was not reported. The age range was 18 to 59 (54.68%). The median time between COVID-19 and PFP was three days (ranging from the first symptom of COVID-19 to 40 days after the acute phase of infection). Late PFP associated with COVID-19 presents mild symptoms and improves with time, with no identified predictors. Late PFP should be added to the spectrum of neurological manifestations associated with the long-term effects of SARS-CoV-2 infection as a post COVID-19 condition.

Facial Palsy with Tongue Ulcer: A Rare Initial Presentation of Granulomatosis with Polyangiitis

ABSTRACT@#Granulomatosis with polyangiitis (GPA) is a rare multisystem disease. Although GPA is rare, it commonly presents in a localised stage where its manifestation involves the upper or lower respiratory tract before progressing to a generalised stage. Therefore, most patients with GPA will visit an oral surgeon or an otolaryngologist to seek treatment. However, the diagnosis of GPA is often delayed as GPA is not frequently considered as a differential diagnosis in common oral and facial diseases. The lack of gold standard investigation for the diagnosis of GPA makes management of this case, a diagnostic conundrum. We herein report a patient who was diagnosed with bilateral acute otitis media and left mastoiditis complicated with facial nerve palsy, and later developed tongue ulceration one month after his initial presentation. The ear, facial and oral symptoms represent a diagnostic red herring to a full-blown generalised stage of GPA.

Application of Artificial Intelligence in Recognition and Evaluation of Facial Paralysis / 中国医疗器械杂志

This paper reviews some recent studies on the recognition and evaluation of facial paralysis based on artificial intelligence. The research methods can be divided into two categories: facial paralysis evaluation based on artificial selection of patients' facial image eigenvalues and facial paralysis evaluation based on neural network and patients' facial images. The analysis shows that the method of manual selection of eigenvalues is suitable for small sample size, but the classification effect of adjacent ratings of facial paralysis needs to be further optimized. The neural network method can distinguish the neighboring grades of facial paralysis relatively well, but it has a higher requirement for sample size. Both of the two methods have good prospects. The features that are more closely related to the evaluation scale are selected manually, and the common development direction may be to extract the time-domain features, so as to achieve the purpose of improving the evaluation accuracy of facial paralysis.

WU Xu's experience of sequential therapy for peripheral facial paralysis / 中国针灸

The paper introduces professor WU Xu 's experience of sequential therapy for peripheral facial paralysis. The sequential therapy refers to a staging treatment, but not rigidly adheres to it. With this therapy, the acupuncture- moxibustion regimen is modified flexibly in line with the specific symptoms of illness. At the acute phase of peripheral facial paralysis, warm acupuncture at Wangu (GB 12) is predominated and electroacupuncture is not recommended at the acupoints on the face. At the recovery phase, warm acupuncture at Zusanli (ST 36) is the main therapy and electroacupuncture is applied to the acupoints on the face appropriately. Besides, for the intractable case, the tapping technique with plum-blossom needle or skin needle should be combined and exerted in the local affected region. At the sequelae phase, in order to shorten the duration of illness, depending on the different types of facial paralysis, i.e. stiffness type, spasmodic type and flaccid type, the corresponding needling techniques are provided, i.e. bloodletting and moxibustion, strong stimulation with contralateral acupuncture and the technique for promoting the governor vessel and warming up yang.

Masseteric-Facial Anastomosis: A Report of Three Cases

Intoduction The pathways of the facial nerve are variable, and knowledge of that is essential. The worst impact caused by facial paralysis is related to quality of life, especially regarding the self-esteem and social acceptance on the part of the patients, leading to social isolation and disruption on their mental health. Case Report A 33-year-old female patient, with a stage-T3 acoustic neurinoma, presented with a moderate dysfunction (grades II to III) according to the House- Brackmann (HB) Facial Nerve Grading System. A 43-year-old male patient, with a stage- T4B trigeminal schwannoma, underwent a resective surgery and presented grade-VI dysfunction according to the HB scale. And a female patient with a stage-T4A acoustic neurinoma presented grade-IV dysfunction according to the HB scale. Discussion We performed a literature review of papers related to surgeries for masseteric-facial nerve anastomosis and compiled the results in table; then, we compared these data with those obtained from our cases. Conclusion The masseteric nerve is the one that shows the best prognosis among all the cranial nerves that could be used, but it is also necessary to perform well the surgical technique to access the facial branch and consequently achieve a better masseteric-facial nerve anastomosis.

Síndrome de Ramsay-Hunt: a propósito de dos casos en que se identificó el genoma del virus de la varicela-zóster en líquido cefalorraquídeo / Ramsay-Hunt syndrome: Report of two cases with identification of the varicella zoster virus genome in cerebrospinal fluid

Resumen | Como los otros herpesvirus alfa, el virus de la varicela-zóster (VZV) permanece en estado de latencia en los ganglios neurales después de la infección primaria (varicela). La reactivación de una infección latente por VZV en los ganglios de la raíz dorsal, produce el herpes zóster. La erupción que este provoca se caracteriza por lesiones cutáneas metaméricas que se acompañan de dolor neurítico y comprometen con mayor frecuencia a ancianos y sujetos inmunocomprometidos, en especial, aquellos infectados con el virus de la inmunodeficiencia humana (HIV). Las complicaciones que se observan en esta población de pacientes incluyen neumonía, hepatitis y compromiso del sistema nervioso central (meningitis y encefalitis). Varios síndromes clínicos se asocian con el herpes zóster de localización craneal, incluida la parálisis facial periférica y el síndrome de Ramsay-Hunt, el cual constituye la segunda causa de parálisis facial periférica y tiene una gran variedad de presentaciones clínicas. La parálisis facial se presenta en 60 a 90 % de los casos de síndrome de Ramsay-Hunt, puede preceder o aparecer después de las lesiones cutáneas y tiene peor pronóstico que la parálisis de Bell. Se describen aquí dos casos de herpes zóster del ganglio geniculado, con parálisis facial periférica que coincidió con la aparición de las lesiones cutáneas vesiculosas en el conducto auditivo externo y el pabellón auricular (síndrome de Ramsay-Hunt multimetamérico). En ambos casos, se identificó el genoma del VZV mediante PCR en el líquido cefalorraquídeo (LCR).

Abstract | Like other alpha-herpesviruses, the varicella-zoster virus (VZV) remains latent in the neural ganglia following the primary varicella infection. The reactivation of the VZV in the dorsal root ganglia results in herpes zoster. Herpes zoster eruption is characterized by localized cutaneous lesions and neuralgic pain mostly in older and immunocompromised persons, especially those living with the human immunodeficiency virus (HIV). The most commonly reported complications include VZV pneumonia, meningitis, encephalitis, and hepatitis. Several neurologic syndromes have been described associated with herpes zoster localized in cranial areas including peripheral nerve palsies and the Ramsay-Hunt syndrome, which has a varied clinical presentation and is the second most common cause of peripheral facial paralysis. Facial paralysis in this syndrome occurs in 60 to 90% of cases and it may precede or appear after the cutaneous lesions with a worse prognosis than idiopathic Bell paralysis. Here we present two cases of herpes zoster from the geniculate ganglia with peripheral facial paralysis that appeared simultaneously with vesicular herpetic otic lesions (multimetameric Ramsay-Hunt syndrome). In the two cases, amplifiable varicella-zoster viral DNA was found in the cerebrospinal fluid by RT-PCR Multiplex.

Manejo terapéutico kinésico en pacientes pediátricos con parálisis facial sometidos a cirugía reconstructiva / Kinesic therapeutic management in pediatric patients with facial palsy undergoing reconstructive surgery

La Parálisis Facial (PF) es una condición infrecuente en pacientes pediátricos, representa un problema clínico relevante y conlleva diversas implicaciones. Tanto el curso natural como el tratamiento y pronóstico no se encuentran bien documentados en la literatura, más aún en sujetos sometidos a cirugía. Se presentan 2 casos de PF sometidos a cirugía reconstructiva, niño de 9 años y niña de 8, ambos casos revisados de forma retrospectiva. Se planteó un bordaje y evaluación kinésica estructurado como tratamiento para estos pacientes. El sistema de graduación facial Sunnybrook (SGFS) fue usado para evaluar resultados funcionales. Durante el seguimiento los sujetos mostraron mejoras continuas con una ganancia promedio de 30 puntos en el SGFS. En nuestra experiencia, la rehabilitación kinésica estructurada con el enfoque presentado, parece ser un coadyuvante efectivo en potenciar el proceso de recuperación de la función muscular y simetría facial en sujetos con PF sometidos a cirugía reconstructiva.

Facial Palsy (FP) is an uncommon condition in pediatric patients, it represents a serious linical problem and carries various implications. Both the natural course, as well as the treatment and prognosis are not well documented in the literature especially in subjects undergoing surgery. Two cases of FP undergoing reconstructive surgery are presented, a 9-year-old boy and an 8-year-old girl, both cases reviewed retrospectively. A structured kinesic approach and valuation was proposed as a treatment for these patients. The Sunnybrook Facial Grading System (SGFS) was applied to evaluate functional outcomes. During follow-up the subjects showed continuous improvement with an average increment of 30 points in the SGFS. In our experience, structured kinesic rehabilitation with the approach presented, seems to be an effective adjunct in enhancing the process of recovery of muscle function and facial symmetry in subjects with FP undergoing reconstructive surgery.

Hypoglossal-Facial Anastomosis for Facial Nerve Reconstruction: Outcomes using the Side-to-End Surgical Technique

Introduction The side-to-end hypoglossal-facial anastomosis (HFA) technique is an excellent alternative technique to the classic end-terminal anastomosis, because itmay decrease the symptoms resulting from hypoglossal-nerve transection. Methods Patients with facial nerve palsy (House-Brackmann [HB] grade VI) requiring facial reconstruction from 2014 to 2017were retrospectively included in the study. Results In total, 12 cases were identified, with a mean follow-up of 3 years. The causes of facial paralysis were due to resection of posterior-fossa tumors and trauma. There was improvement in 91.6% of the patients (11/12) after the HFA. The rate of improvement according to the HB grade was as follows: HB III - 58.3%; HB IV - 16.6%; and HB II - 16.6%. The first signs of improvement were observed in the patients with the shortest time between the paralysis and the anastomosis surgery (3.5months versus 8.5 months; p » 0.011). The patients with HB II and III had a shorter time between the diagnosis and the anastomosis surgery (mean: 5.22 months), while the patients with HB IV and VI had a longer time of paresis (mean: 9.5 months; p » 0.099). We did not observe lingual atrophy or changes in swallowing. Discussion and Conclusion Hypoglossal-facial anastomosis with the terminolateral technique has good results and low morbidity in relation to tongue motility and swallowing problems. The HB grade and recovery appear to be better in patients operated on with a shorter paralysis time.

Síndrome de Ramsay Hunt: reporte de un caso clínico / Ramsay Hunt Syndrome: clinical case report

El virus varicela zoster produce cuadros clínicos por reactivación del mismo en años posteriores a la primoinfección, en sujetos con condiciones particulares, como situaciones de estrés, inmunodepresión, radioterapia, estados infecciosos que cursen con fiebre, entre otros.

Craniofacial and neurological manifestations in patients with Guillain-Barré syndrome / Manifestaciones neurológicas craneofaciales en pacientes con síndrome de Guillain-Barré

Introducción: Among the broad range of symptoms of the Guillain-Barré Syndrome (GBS), patients can present craniofacial manifestations. Consequently, the participation of the dental surgeon in the evaluation of the stomatognathic system using a multidisciplinary approach model is very important. Objective: To identify the craniofacial and neurological manifestations of the Guillain-Barré Syndrome in patients from three hospitals in the district of Lambayeque, Peru, in 2019. Material and Methods: A descriptive, prospective, and cross-sectional study was carried out in 59 patients diagnosed with GBS by means of a clinical evaluation carried out by previously calibrated neurologists (k=0.911). Additionally, an oral evaluation of the oral hygiene index, the periodontal status, and the oral pH was carried out. Data were processed using frequency distribution tables. Results: 4 4.07% of the patients presented at least one functional alteration, such as unilateral limitation for facial expressions (25.42%), dysphagia (18.64%), alteration in phonation (11.86%), and loss of the sense of taste (6.78%), showing involvement of the corresponding cranial nerves. In addition, unfavorable conditions of oral hygiene and acid pH were observed in some cases, which proved adverse for the periodontal structures of the patients. Conclusion: The study found craniofacial manifestations of GBS, such as cases of unilateral facial palsy, dysphagia, difficulty in phonation, and loss of the sense of taste, due to the alteration of the cranial nerves that command these functions. In addition, poor oral hygiene, and the presence of acidic pH in some patients created an adverse environment for the integrity of the periodontal structures

Introducción: El Síndrome de Guillain-Barré (SGB) dentro de su amplia sintomatología puede presentar manifestaciones craneofaciales, por lo que resulta importante la participación del cirujano dentista en la evaluación del sistema estomatognático desde un modelo de abordaje multidisciplinario. Objetivo: Identificar las manifestaciones neurológicas craneofaciales del Síndrome de Guillain-Barré en pacientes de tres establecimientos de salud de Lambayeque, Perú en el año 2019. Materiales y Metodos: Se realizó un estudio descriptivo, prospectivo y transversal, con 59 pacientes diagnosticados con SGB, mediante una evaluación clínica realizada por médicos neurólogos previamente calibrados (k=0,911). Adicionalmente se realizó una evaluación bucodental del índice de higiene oral, del estado periodontal y del pH bucal, siendo procesados los datos mediante tablas de distribución de frecuencias. Resultados: El 44,07% de pacientes presentaron por lo menos una alteración funcional, identificando limitación unilateral para expresiones faciales (25.42%), disfagia (18.64%), alteración en la fonación (11.86%) y pérdida del sentido del gusto (6.78%), evidenciando compromiso de los pares craneales correspondientes. Además se observaron condiciones desfavorables de higiene oral y de pH ácido en algunos casos, que resultaron adversas para las estructuras periodontales de los pacientes. Conclusión: Fueron encontradas manifestaciones craneofaciales del SGB, identificando casos con parálisis facial unilateral, disfagia, dificultad para la fonación y pérdida del sentido del gusto, debido a la alteración de los pares craneales que comandan esas funciones. Además las condiciones desfavorables de higiene oral y la presencia de pH ácido en algunos casos, propiciaron un ambiente adverso para la integridad de las estructuras periodontales.
