SUMMARY: Subjects with maxillary skeletal classes II and III not only express alterations in the hard and soft maxillofacial tissues, but also in the morphology and dimensions of the upper airway. A small space in the upper airway has been associated with sleep disorders, such as snoring and mainly obstructive sleep apnea/hypopnea syndrome (OSAHS). Consequently, interest has increased due to the influence of orthognathic surgery in the airway space. Although there are studies in the literature that have compared upper airway spaces, most have evaluated the changes using two-dimensional images, mainly lateral skull X-rays. The present study aimed to determine the airway volume in subjects with skeletal classes II and III who underwent bimaxillary orthognathic surgery. 80 CBCT exams from 40 subjects obtained before and 6 months after surgery were used. There were 20 class II and 20 class III subjects. For the volumetric analysis, a 3D rendering of the upper airway was made in previously established segments, and then the airway volume was calculated using the 3D Slicer® software version 4.11 (Slicer, USA). The statistical analysis by t-test of related samples revealed statistically significant volumetric increases in the nasopharynx, laryngopharynx, and total volume in class II patients. However, in class III patients, there were significant increases in the nasopharynx and total volume, while the volume was maintained in the oropharynx and laryngopharynx.
Sujetos con clases esqueletales II y III maxilares, no solamente expresan alteraciones en los tejidos duros y blandos maxilofaciales, sino también en la morfología y dimensiones de la vía aérea superior. Un espacio reducido a nivel de la vía aérea superior se asocia a trastornos del sueño como ronquidos y principalmente el síndrome de apnea/hipoapnea obstructiva del sueño (AOS); debido a esto, ha aumentado el interés por la influencia de la cirugía ortognática en el espacio de la vía aérea. Si bien existen en la literatura estudios que han comparado los espacios de la vía aérea superior, la mayoría de los estudios han evaluado los cambios utilizando imágenes bidimensionales, principalmente radiografías laterales de cráneo. El objetivo del presente estudio fue determinar el volumen de la vía aérea en sujetos con clases esqueletales II y III sometidos a cirugía ortognática bimaxilar. Se utilizaron 80 exámenes CBCT pertenecientes a 40 sujetos obtenidos previo a la cirugía y 6 meses después de realizada. Veinte sujetos clase II y 20 clase III. Para el análisis volumétrico se realizó un renderizado 3D de la vía área superior en segmentos previamente establecidos y posteriormente se calculó el volumen de dicha vía aérea con la utilización del software 3D Slicer ®versión 4.11 (Slicer, USA). El análisis estadístico realizado por t-test de muestras relacionadas, arrojó en pacientes clase II aumentos volumétricos estadísticamente significativos en nasofaringe, laringofaringe y volumen total. Mientras que en pacientes clase III, se observó aumentos significativos en Nasofaringe y volumen total y mantención de volumen en orofaringe y laringofaringe.

OBJECTIVE@#To observe the clinical efficacy on post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation.@*METHODS@#Sixty patients with post-stroke dysphagia were randomly divided into an observation group and a control group, with 30 cases in each group. The neuromuscular electrical stimulation was adopted in the control group. Besides the treatment as the control group, in the observation group, the four-step acupuncture therapy for opening orifices and benefiting throat was supplemented. Step 1: the three areas of scalp acupuncture on the affected side were stimulated. Step 2: pricking method was operated on the posterior pharyngeal wall. Step 3: bleeding technique was operated at Jinjin (EX-HN 12) and Yuye (EX-HN 13). Step 4: deep insertion of needle was operated at three-pharynx points. The needles were retained for 30 min at the three areas of scalp acupuncture and the three-pharynx points. The intervention of each group was delivered once daily, 6 times a week, at the interval of 1 day. One course of treatment was 1 week and 4 successive courses were required. The rating of Kubota water swallow test, the score of standardized swallowing assessment (SSA) and the rating of Rosenbek penetration- aspiration scale (PAS) were observed before and after treatment in patients of the two groups. The incidence of clinical complications and clinical efficacy were compared between the two groups.@*RESULTS@#Compared with those before treatment, the rating of Kubota water swallow test, the scores of SSA and the rating of PAS of patients in the two groups were decreased after treatment (P<0.01), and the values of the observation group were lower than those of the control group after treatment (P<0.05). The incidence of clinical complications in the observation group was 13.3% (4/30), lower than 36.7% (11/30) in the control group (P<0.05). The total effective rate in the observation group was 93.3% (28/30), which was better than 70.0% (21/30) in the control group (P<0.05).@*CONCLUSION@#The four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation can improve the swallowing function of patients with post-stroke dysphagia and reduce the incidence of clinical complications.

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)

Objective:To compare the changes of morphology of pharynx in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and healthy individuals during oral or nasal breathing, and explore the relevant influencing factors. Methods:Twenty-nine adult patients with OSAHS and 20 non-snoring controls underwent MRI to obtain upper airway structural measurements while the subjects were awake and during mouth breathing with a nasal clip.The following were analyzed. ①The changes of upper airway structure of oral and nasal respiration in non-snoring control/OSAHS patients were observed; ②The differences and influencing factors of upper airway structure changes between OSAHS patients and controls were compared during breathing. Results:The control group consisted of 15 males and 5 females, with an apnea-hypopnea index (AHI)<5 events/h, while the OSAHS group comprised 26 males and 3 females with an AHI of 40.4±23.1 events/h and the mean lowest arterial oxygen saturation (LSaO2) was 79.5% ±10.0%. In the both groups, the vertical distance between the mandible and the posterior pharyngeal wall decreased (P<0.05); The long axis of tongue body decreased (P<0.05), and the contact area between tongue and palate decreased. There was no significant change in the total volume of the retropalatine(RP) and retroglossal(RG) airway in the control group (P>0.05). However, the minimum cross-sectional area and volume of the RP airway in OSAHS decreased (P<0.001). The lateral diameters of uvula plane in OSAHS decreased during mouth breathing, which was contrary to the trend in the control group (P=0.017). The AHI of patients was positively correlated with the reduction of the volume of the RP airway during oral breathing (P=0.001); The reduction of the distance between the mandible and the posterior pharyngeal wall was positively correlated with the length of the airway (P<0.001). Conclusion:Mouth breathing leads to the shortening of the long axis of the tongue, the reduction of the contact area between the soft palate and the tongue, vertical distance between the mandible and the posterior pharyngeal wall, and the cross-sectional area of the epiglottis plane. These changes vary between OSAHS patients and controls. During mouth breathing, the diameters, areas and volumes of the RP area decreased, and were more significant in severe cases.

Objective:To study the application value of narrow-band imaging in the diagnosis of laryngopharyngeal reflux. Methods:A total of 275 patients admitted to the inpatient department or laryngoscopy room of the Otolaryngology Head and Neck Surgery Department of the First Affiliated Hospital of Harbin Medical University from September 2022 to April 2023 due to throat discomfort were selected as the research subjects. All of them completed RSI, RFS scoring scales and electronic laryngoscopy(including ordinary white light and NBI). According to the expert consensus of LPRD in 2022, RSI and RFS scoring scale were used as diagnostic criteria to divide them into LPR group and non-LPR group. Chi-square test was used to analyze the differences of positive rates of characteristic manifestations under NBI among different groups. The consistency of NBI and scale diagnostic methods was analyzed by Kappa, and RSI and RFS scoring were used as diagnostic criteria, The diagnostic efficiency of NBI method was analyzed. Results:There were 190 people in the LPR group, 157 of whom showed characteristic performance under the NBI mode, with a positive rate of 82.6%(157/190); there were 85 people in the non-LPR group, with a positive rate of 18.8%(16/85). There was a statistically significant difference in the positive rate between the two groups(χ²=102.47, P<0.05). The consistency rate between RSI, RFS and NBI was 82.2%(226/275). Kappa consistency analysis was used, and Kappa=0.605(P<0.05), indicating good consistency between the two diagnostic methods. Using RSI and RFS as diagnostic criteria for LPR, the sensitivity of NBI diagnostic method was 82.6%(157/190), specificity 81.2%(69/85), positive predictive value 90.8%(157/173) and negative predictive value 67.6%(69/102). Conclusion:Narrow-band imaging, as a new endoscopic imaging technique, can show small changes in mucosal surface micro vessels and play an important role in the diagnosis of laryngopharyngeal reflux.

OBJECTIVES@#To investigate the positive rate of enterovirus (EV) nucleic acid in throat swabs of term late neonates hospitalized during the coronavirus disease 2019 (COVID-19) epidemic and the clinical characteristics of the neonates.@*METHODS@#A single-center cross-sectional study was performed on 611 term late infants who were hospitalized in the neonatal center from October 2020 to September 2021. Throat swabs were collected on admission for coxsackie A16 virus/EV71/EV universal nucleic acid testing. According to the results of EV nucleic acid test, the infants were divided into a positive EV nucleic acid group (8 infants) and a negative EV nucleic acid group (603 infants). Clinical features were compared between the two groups.@*RESULTS@#Among the 611 neonates, 8 tested positive for EV nucleic acid, with a positive rate of 13.1‰, among whom 7 were admitted from May to October. There was a significant difference in the proportion of infants contacting family members with respiratory infection symptoms before disease onset between the positive and negative EV nucleic acid groups (75.0% vs 10.9%, P<0.001). There were no significant differences between the two groups in demographic data, clinical symptoms, and laboratory test results (P>0.05).@*CONCLUSIONS@#There is a certain proportion of term late infants testing positive for EV nucleic acid in throat swabs during the COVID-19 epidemic, but the proportion is low. The clinical manifestations and laboratory test results of these infants are non-specific. Transmission among family members might be an important cause of neonatal EV infection.

OBJECTIVES@#To investigate the distribution characteristics and correlation of intestinal and pharyngeal microbiota in early neonates.@*METHODS@#Full-term healthy neonates who were born in Shanghai Pudong New Area Maternal and Child Health Hospital from September 2021 to January 2022 and were given mixed feeding were enrolled. The 16S rRNA sequencing technique was used to analyze the stool and pharyngeal swab samples collected on the day of birth and days 5-7 after birth, and the composition and function of intestinal and pharyngeal microbiota were analyzed and compared.@*RESULTS@#The diversity analysis showed that the diversity of pharyngeal microbiota was higher than that of intestinal microbiota in early neonates, but the difference was not statistically significant (P>0.05). On the day of birth, the relative abundance of Proteobacteria in the intestine was significantly higher than that in the pharynx (P<0.05). On days 5-7 after birth, the relative abundance of Actinobacteria and Proteobacteria in the intestine was significantly higher than that in the pharynx (P<0.05), and the relative abundance of Firmicutes in the intestine was significantly lower than that in the pharynx (P<0.05). At the genus level, there was no significant difference in the composition of dominant bacteria between the intestine and the pharynx on the day of birth (P>0.05), while on days 5-7 after birth, there were significant differences in the symbiotic bacteria of Streptococcus, Staphylococcus, Rothia, Bifidobacterium, and Escherichia-Shigella between the intestine and the pharynx (P<0.05). The analysis based on the database of Clusters of Orthologous Groups of proteins showed that pharyngeal microbiota was more concentrated on chromatin structure and dynamics and cytoskeleton, while intestinal microbiota was more abundant in RNA processing and modification, energy production and conversion, amino acid transport and metabolism, carbohydrate transport and metabolism, coenzyme transport and metabolism, and others (P<0.05). The Kyoto Encyclopedia of Genes and Genomes analysis showed that compared with pharyngeal microbiota, intestinal microbiota was more predictive of cell motility, cellular processes and signal transduction, endocrine system, excretory system, immune system, metabolic diseases, nervous system, and transcription parameters (P<0.05).@*CONCLUSIONS@#The composition and diversity of intestinal and pharyngeal microbiota of neonates are not significantly different at birth. The microbiota of these two ecological niches begin to differentiate and gradually exhibit distinct functions over time.

Resumen La insuficiencia velofaríngea (IVF) es una de las principales secuelas estructurales tras la palatoplastía primaria en casos de fisura de paladar. La IVF se caracteriza por la ausencia de tejido suficiente para lograr un cierre adecuado del mecanismo velofaríngeo durante el habla, lo que conlleva a una resonancia hipernasal y la emisión nasal de aire durante la producción de sonidos orales. Al respecto, el tratamiento ideal para corregir la IVF es quirúrgico, dentro de los cuales el colgajo faríngeo de pedículo superior es uno de los procedimientos más utilizados en nuestro país. Para su realización es fundamental determinar el ancho necesario, lo cual puede ser determinado mediante una videofluoroscopía multiplano (VFMP). Por esto, con el objetivo de potenciar el trabajo multidisciplinario en la corrección quirúrgica de la IVF, a continuación, se presentan los procedimientos de evaluación fonoaudiológica, videonasofaríngoscopía flexible y videofluoroscopía multiplano utilizados para la planificación quirúrgica de un colgajo faríngeo en un adolescente chileno diagnosticado con IVF secundaria a fisura palatina operada. Además, se describe el uso de la VFMP en la planificación quirúrgica del colgajo faríngeo mediante una revisión de literatura.
Abstract Velopharyngeal insufficiency (VPI) is one of the main structural sequelae after primary palatoplasty in cases of cleft palate. VPI is characterized by the absence of sufficient tissue to achieve adequate closure of the velopharyngeal mechanism (VFM) generating hyper-nasal resonance and nasal emission during the production of oral sounds. In cases of cleft palate, the ideal treatment to correct VPI is surgery. The upper pedicle pharyngeal flap is one of the most widely used procedures. To plan it, is essential to determine the appropriate width, which can be determined by means of multiplane videofluoroscopy (MPVF). For this reason, and with the aim of promoting multidisciplinary approach in the surgical correction of VPI, the following procedures such as speech and language evaluation, flexible videonasopharyngoscopy and multiplane videofluoroscopy used for the surgical planning of a pharyngeal flap, in a Chilean adolescent diagnosed with VPI secondary to operated cleft palate, will be presented. In addition, the use of MPVF in pharyngeal flap surgical planning is described through a literature review.

Métodos: Trata-se de um estudo observacional, transversal, de abordagem quantitativa, aprovado em janeiro pelo CEP/UFSCPA (número 1.389.050). Todos os participantes do estudo assinaram o termo de consentimento livre e esclarecido. A fase faríngea da deglutição foi avaliada por meio de ausculta cervical e eletromiografia de superfície. Os indivíduos ingeriram 90 ml de água. Os dados da ausculta foram transferidos para o DeglutiSom® software, a duração e amplitude da atividade eletromiográfica foram mensuradas durante a deglutição com aparelho de eletromiografia de superfície Miotec®. O nível de significância adotado foi de 5%. Resultados:Cinquenta e sete mulheres participaram deste estudo. A média de idade foi de 23,4 anos. Ressalta-se que quanto maior a frequência média do pico da ausculta, menor é a média do pico do músculo supra-hióideo e quanto maior a intensidade, maior é o pico, assim como a média dos picos supra-hióideos. Foi possível demonstrar que o pico de atividade do músculo supra-hióideo foi significativamente maior do que o pico de atividade do músculo infra-hióideo para a deglutição de 90 ml de água. Conclusão:Os parâmetros acústicos da deglutição em indivíduos saudáveis estão correlacionados com a atividade elétrica dos músculos envolvidos na fase faríngea da deglutição.
Objective: Correlate the acoustic data of cervical auscultation to the electrical activity of the muscles involved in the pharyngeal phase of swallowing. Methods: This is an observational, cross-sectional study involving a quantitative approach and was approved on January by CEP/UFSCPA (number 1.389.050). All participants of the study signed an informed consent form. The pharyngeal phase of swallowing was assessed by employing auscultation and surface electromyography. Individuals ingested 90 ml of water. The auscultation data were transferred to DeglutiSom® software, the duration and amplitude of electromyographic activity was measured during swallowing using a Miotec® surface electromyography device. The level of significance adopted was 5%. Results: Fifty-seven women participated in this study. The average age was 23.4 years on average. It must be highlighted that the greater the average peak frequency of auscultation, lower was the average peak of the suprahyoid muscle and the greater the intensity, the greater was the peak, as well as the average of the suprahyoid peaks. It was possible to demonstrate that the peak of suprahyoid muscle activity was significantly higher than the peak of infra hyoid muscle activity for swallowing 90 ml of water. Conclusion: The acoustic swallowing parameters in healthy individuals are correlated with the electrical activity of muscles involved in the pharyngeal phase of swallowing.

Objectives: To analyze the clinical characteristics and outcomes of neonates with upper airway obstruction (UAO) who were admitted via transportation, hence to provide more evidence-based information for the clinical management of UAO. Methods: This was a single center retrospective study. Patients were hospitalized in Beijing Children's Hospital from January 1, 2016 to May 31, 2021 with age <28 days or postmenstrual age (PMA) ≤44 weeks, and UAO as the first diagnosis. The general information of patients, obstructed sites in the upper airway, treatment, complications and prognosis were analyzed. The outcomes of surgical UAO vs. non-surgical UAO were analyzed by 2 by 2 χ2 test. Results: A total of 111 cases were analyzed (2.3% of the total NICU hospitalized 4 826 infants in the same period), in which 62 (55.9%) were boys and 101 (91.0%) were term infants, and their gestational age was (38.7±2.0) weeks, birth weight (3 207±585) g, PMA on admission (40.8±2.5) weeks and weight on admission was (3 221±478) g. There were 92 cases (82.9%) with symptoms of UAO presenting on postnatal day 1, and 35 cases (31.5%) had extra-uterine growth retardation on admission. The diagnosis of UAO and the obstructive site was confirmed in 25 cases (22.5%) before transportation. There were 24 cases (21.6%), 71 cases (64.0%), and 16 cases (14.4%) who had UAO due to nasal, throat, and neck problems, respectively. The top 5 diagnosis of UAO were vocal cord paralysis (28 cases), bilateral choanal atresia (20 cases), laryngomalacia (15 cases), pharynx and larynx cysts (7 cases), and subglottic hemangioma (6 cases). The diagnosis and treatment of all the patients followed a multidisciplinary approach consisted of neonatal intensive care unit, ear-nose-throat department and medical image departments. A total of 102 cases (91.9%) underwent both bronchofiberscope and fiber nasopharyngoscope investigation. Seventy cases (63.1%) required ventilation. Among the 58 cases (52.3%) who required surgical intervention, 16 had tracheotomy. For cases with vs. without surgical intervention, the rate of cure and (or) improvement were 94.8% (55/58) vs. 54.7% (29/53), and the rate of being discharged against medical arrangement were 1.7% (1/58) vs. 45.3% (24/53) (χ²=24.21 and 30.11, both P<0.01). Conclusions: Neonatal UAO may locate at various sites of the upper airway. The overall prognosis of neonatal UAO is favorable. A multidisciplinary approach is necessary for efficient evaluation and appropriate surgical intervention.

Objective: To explore the surgical methods and effects of transoral endoscopic resection of benign tumors in parapharyngeal space via medial pterygomandibular raphe approach. Methods: The clinical data of 23 patients who underwent resection of benign tumors in parapharyngeal space by endoscopic medial pterygomandibular raphe approach from January 2016 to July 2020 in the Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University were analyzed retrospectively. There were 14 males and 9 females with a median age of 43 years. The tumors were located in the anterior space of the styloid process in 13 cases and in the posterior space in 10 cases. The smallest tumor volume was 7.3 ml and the largest was 80.2 ml. The preoperative imaging features, the characteristics and risks of this approach in the operation were analyzed, and the feasible mode of operation was explored. Results: All patients completed the operation successfully. The intraoperative blood loss was 20 to 50 ml, with an average of 28.3 ml. The operation time was 40 to 110 min, with an average of 75.4 min. The incision length was 2 to 4 cm, with an average of 3.0 cm. The postoperative pain score was 2 to 4, with an average of 3.2. The postoperative hospital stay was 4 to 9 d, with an average of 6.7 d. Postoperative pathological diagnosis included pleomorphic adenoma (n=12), neurilemmoma (n=10) and basal cell adenoma (n=1). The patients were followed up for 6 to 60 months. There was no postoperative complication such as infection or serious bleeding, and there was no tumor recurrence after operation. Conclusion: Endoscopic resection of benign tumor in parapharyngeal space via medial pterygomandibular raphe approach is a safe, effective, and minimally invasive surgical method for the treatment of tumors in parapharyngeal space.

SUMMARY: The aim of this research was to evaluate the changes obtained with the mentoplasty technique in the increase of the airway imaging. A systemic review was performed using the parameters of the prism matrix, in the PubMed, Science Direct, Redalyc database, covering the years 1984 to 2019 with the use of defined inclusion criteria. The authors independently applied the selected parameter of data extraction, study selection and risk-to-bias assessment. A total of 1,251 articles were obtained among the 3 databases, of which 10 met the inclusion criteria. The variables studied were: type of research, sample size, sex, age, dento-skeletal diagnosis, airway classification, diagnosis of obstructive sleep apnea syndrome (OSAS), type of imaging evaluation, variables evaluated in the image, pre and post-operative values, surgical technique and type of fixation used, other surgical procedures applied, and complications. In the cases of linear evaluation with cephalometric analysis (9 articles) they used PAS (posterior airspace), MP-H (mandibular plane to the hyoid) and SNB (saddle-nasion-point B), and SCSA (section area as the most relevant points, smallest cross section) and VT (total volume) in the volumetric evaluations (2 articles). The average change in posterior airspace achieved by the cited authors is 4.2 mm with standard deviation of 1.4 mm with the use of advancement mentoplasty. The most widely used technique was mentoplasty with a horizontal osteotomy by 5 authors. Based on the research there is a positive relationship between the increase in the airway and the advancement mentoplasty procedure, however, more standardized studies associated with the way of measuring and evaluating the relationship between advancement and the airway are necessary.
RESUMEN: El objetivo de esta investigación fue evaluar los cambios obtenidos con la técnica de mentoplastia en el incremento de la via aérea. Una revisión sistemática fue realizada utilizando parámetros de la matriz prisma, en PubMed, Science Direct, Redalyc database, cubriendo los años 1984 a 2019 con criterios de inclusión definidos. Los autores aplicaron de forma independiente los parámetros de selección y extracción de datos, selección de estudios y riesgos de sesgo. Un total de 1251 artículos fueron obtenidos de las 3 bases de dato, donde 10 artículos cumplieron los criterios de inclusión. Las variables estudiadas fueron: tipo de investigación, tamaño de la muestra, genero, edad, diagnóstico dento esqueletal, clasificación de la vía aérea, diagnostico de síndrome de apnea del sueño (SAOS), tipo de evaluación de la imagen, variables evaluadas en la imagen en pre y postoperatorio, técnica quirúrgica y tipo de fijación utilizada, otros procedimientos quirúrgicos y complicaciones. En el caso de la evaluación linear con cefalometria (9 artículos), usaron PAS (posterior airspace), MP-H (plano mandibular hacia el hueso hioide) y SNB (silla turca-nasion- punto B) y SCSA (sección de puntos mas relevantes, menores transfversales) y el VT (volumen total) en las evaluaciones volumétricas (2 artículos). El promedio de cambio posterior de la vía aérea citado por autores fue de 4,2 mm con una desviación estándar de 1,4 mm con el uso de la mentoplastia de avance. La técnica mas habitual fue la mentoplastia con osteotomía horizontal (5 autores). Basados en esta investigación existe una relación positiva entre el incremento de la vía aérea y el avance con genioplastia; sin embargo, mas estudios estandarizados junto con medidas definidas y la evaluación correcta del avance y la vía área son necesarios.

Introducción. El divertículo de Zenker es una evaginación sacular ciega que puede presentarse a nivel faringoesofágico. No se conoce exactamente su incidencia en la edad pediátrica, constituyendo una patología muy infrecuente. La sintomatología es inespecífica, lo que dificulta el diagnóstico precoz y determina un mayor riesgo de complicaciones asociadas. Caso clínico. Paciente preescolar femenina con cuadro recurrente de emesis con deshidratación, posteriormente asociado a disfagia, a quien se le diagnosticó un divertículo de Zenker. Se realizó tratamiento quirúrgico con hallazgo intraoperatorio de dilatación esofágica, un área de estenosis secundaria al hallazgo incidental de un cuerpo extraño y divertículo de Zenker en la región lateral del esófago dilatado. Discusión. Esta patología es extremadamente rara, pero se debe tener en cuenta dentro de los diagnósticos diferenciales en pacientes con sintomatología faringo-esofágica. Conclusión. Se presenta una preescolar sin antecedente de procedimientos esofágicos o malformaciones congénitas asociadas con diagnóstico de un divertículo de Zenker y dilatación esofágica por un cuerpo extraño, tratada quirúrgicamente de forma exitosa.
Introduction. Zenker's diverticulum is a blind saccular evagination that can present at the pharyngoesophageal level. Its incidence in pediatric age is not exactly known, constituting a very infrequent pathology. The symptoms are nonspecific, which makes early diagnosis difficult and determines a higher risk of associated complications.Clinical case. Female preschool patient with recurrent dehydration due to emesis, later associated with dysphagia, who was diagnosed with Zenker's diverticulum. Surgical treatment was performed with intraoperative finding of esophageal dilation, an area of stenosis secondary to the incidental finding of a foreign body, and a Zenker's diverticulum in the lateral region of the dilated esophagus. Discussion. This pathology is extremely rare, but it should be taken into account within the differential diagnoses in patients with pharyngo-esophageal symptoms. Conclusion: We present a preschool female patient with no history of esophageal procedures or congenital malformations associated with a diagnosis of Zenker's diverticulum and esophageal dilation due to a foreign body, successfully treated surgically.

Introduction. Due to the COVID-19 pandemic, teaching conditions changed around the world from in-person classes to online classes, which also determined changes on teachers' working conditions. Method: Exploratory cross-sectional study with the aim of determining the association between two voice symptoms (vocal fatigue and throat pain) with home working conditions during online classes in times of COVID-19 pandemic. Professors answered an online survey including 27 questions about four components: sociodemographic factors, characteristics of home working, quarantine characteristics, and health conditions (including voice functioning). Results: 177 college professors from Argentina, Colombia, and Chile participated in this study. First, incidence of vocal fatigue, during online classes in times of COVID-19 pandemic, represented around 50%. Although throat pain had a smaller incidence, it was also important (35%). Second, days in quarantine, number of classes per week, people living with during quarantine, and history of vocal fatigue before quarantine were important associated factors of vocal fatigue. Third, important associated factors of throat pain were number of classes per week, level of stress, years of experience, and history of throat pain before quarantine. Conclusion: Similar to pre-COVID-19, vocal fatigue and throat pain were frequently reported voice symptoms among college professors. Associated factors of these symptoms included years of experience, number of classes per week, stress, people living with during quarantine due to COVID-19, and history of voice symptoms. Workplace Health Promotion programs should include activities that facilitate a healthy occupational voice use during and post-COVID-19 pandemic, considering the implications of online teaching on teachers' health and safety
Introducción: Debido a la pandemia del COVID-19, las condiciones de ense-ñanza-aprendizaje cambiaron alrededor del mundo, pasando de clases presen-ciales a clases virtuales, lo que también determinó cambios en las condiciones de trabajo docente. Métodos: Estudio transversal exploratorio que tuvo como propósito determinar la asociación entre dos síntomas de voz (fatiga vocal y dolor de garganta) con las con-diciones de trabajo docente durante las clases virtuales en tiempos de COVID-19. Los profesores diligenciaron una encuesta virtual que incluyó 27 preguntas sobre los siguientes cuatro componentes: factores sociodemográficos, características del tra-bajo en casa, características de la cuarentena, y condiciones de salud (incluyendo funcionamiento vocal). Resultados: 177 profesores universitarios de Argentina, Colombia y Chile parti-ciparon en este estudio. Primero, la incidencia de la fatiga vocal durante las clases virtuales en tiempos de COVID-19 representó alrededor del 50%. Aunque el dolor de garganta tuvo una menor incidencia, también fue importante (35%). Segundo, los días en cuarentena, número de clases por semana, personas con las que vivió durante la cuarentena, y los antecedentes de fatiga vocal antes de la cuarentena estuvieron estadísticamente asociados a la fatiga vocal. Tercero, los factores asociados al dolor de garganta fueron el número de clases semanales, los niveles de estrés, los años de experiencia y los antecedentes de dolor de garganta antes de la cuarentena.Conclusión: Similar a hallazgos previos al COVID-19, la fatiga vocal y el dolor de garganta son síntomas vocales frecuentemente reportados en docentes universitarios. Factores asociados de estos síntomas incluyen años de experiencia, número de clases semanales, estrés, personas con las que vivió durante la cuarentena y antecedentes de estos síntomas vocales antes del trabajo en casa. Los Programas de Promoción de la Salud en los Lugares de Trabajo deben incluir actividades que faciliten el uso ocupacional saludable de la voz durante y después del COVID-19, considerando las implicaciones de la enseñanza virtual en la salud y seguridad de los profesores.

El ronquido es un problema altamente prevalente, que afecta a millones de personas a nivel mundial. Impacta negativamente en la calidad de vida al afectar la relación de pareja y la calidad de sueño, además de constituir un factor de riesgo cardiovascular. El objetivo de esta revisión es analizar y discutir los aspectos más relevantes de esta condición, desde su etiopatogenia hasta las diferentes alternativas terapéuticas disponibles. En la evaluación del paciente roncador se debe realizar un minucioso examen de nariz, boca, faringe, cuello y esqueleto facial, además de estimar el riesgo de que exista una apnea obstructiva del sueño asociada. Son de utilidad una serie de cuestionarios que permiten asignar puntaje a la sintomatología del paciente y evaluar su impacto en la vida diaria. En general, el estudio deberá incluir exámenes radiológicos, endoscopías de la vía aérea superior (con el paciente despierto y bajo sueño inducido por medicamentos) y estudios del sueño, que se pueden realizar tanto en forma ambulatoria como hospitalizado. Existe una amplia gama de tratamientos disponibles para el ronquido, los que han demostrado una alta efectividad en diferentes subgrupos de pacientes: bajar de peso, dejar de fumar, medicamentos antialérgicos, terapia postural, ejercicios faríngeos, dispositivos de avance mandibular y procedimientos quirúrgicos que van desde intervenciones mínimamente invasivas hasta procedimientos avanzados como cirugía robótica, avances máxilo-mandibulares y la estimulación del nervio hipogloso. Es clave para manejar exitosamente el ronquido el realizar una evaluación detallada del paciente y establecer un plan terapéutico personalizado.
Snoring is a highly prevalent problem, affecting millions of people worldwide. It negatively impacts quality of life by affecting couple relationships and sleep quality, as well as being a cardiovascular risk factor. The aim of this review article is to analyze and discuss the most relevant aspects of this condition, ranging from its etiology and pathogenesis to the different available therapeutic options. When evaluating a snoring patient, a thorough examination of the nose, mouth, pharynx, neck and facial skeleton should be performed, and the risk of having an associated obstructive sleep apnea must be estimated. A series of questionnaires are useful to assign scores to the patient's symptoms and assess their impact on daily life. In general terms, patient evaluation should include radiological examinations, upper airway endoscopies (awake and under drug-induced sleep) and sleep studies, which can be performed both on an outpatient or inpatient basis. There is a wide range of treatments available for snoring, which have shown high effectiveness in different patient subgroups: weight loss, quitting smoking, anti-allergic medications, postural therapy, pharyngeal exercises, mandibular-advancement devices and surgical procedures ranging from minimally invasive interventions to advanced procedures such as robotic surgery, maxillomandibular advancement and hypoglossal nerve stimulation. The cornerstone for a successful snoring management is to perform a detailed patient evaluation and to establish a personalized therapeutic plan.

ABSTRACT BACKGROUND: High-resolution manometry (HRM) represents a potential tool for measuring pharyngoesophageal phonation pressures. OBJECTIVE: This study aims to evaluate pharyngeal, esophageal upper sphincteric and esophageal pressures during different phonation tasks. METHODS: 12 (six males, mean age 27 years) professional singers underwent HRM and produced four different vocal tasks at low, medium and high vocal loudness: vowel /ae/, ascending five note scale, word /hey/ and word /go/. Pressures were measured at pharynx, upper esophageal sphincter (UES) and esophagus. Visual analysis of the HRM topographic plots were performed. RESULTS: Esophageal pressures are higher during vocalization than at rest. Pharyngeal and UES phonation pressures does not differ significantly from rest pressures. Visual analysis of the topographic plots showed an important UES pressure increasement during phonation. CONCLUSION: HRM is a valuable tool for measuring pharyngoesophageal pressures during phonation. Esophageal pressures are higher during phonation than at rest and tend to increase with vocal loudness increment. The topographic plot provides additional data about phonatory mechanism physiology, especially at the UES region.
RESUMO CONTEXTO: A manometria de alta resolução (MAR) é uma ferramenta de grande potencial para mensuração das pressões faringoesofágicas durante a fonação. OBJETIVO: O estudo visa avaliar pressões faringianas, do esfíncter esofagiano superior e do esôfago durante manobras fonatórias. MÉTODOS: Doze (seis homens, idade média 27 anos) cantores profissionais foram submetidos à MAR e produziram quatro tarefas vocais em intensidade baixa, média e alta: vogal / ae /, escala ascendente de cinco notas, palavras /hey/ e /go/. Pressões aos níveis da faringe, esfíncter esofagiano superior e esôfago foram aferidas além de análise visual dos traçados. RESULTADOS: Pressões esofágicas foram maiores na vocalização que no repouso. Pressões da faringe e esfíncter esofagiano superior durante a fonação não foram diferentes que no repouso. Análise visual dos traçados mostrou importante incremento da pressão do esfíncter durante a fonação. CONCLUSÃO: MAR é uma ferramenta valiosa para mensurar as pressões faringoesofágicas durante a fonação. Pressões esofágicas são maiores durante a fonação que no repouso e tendem a aumentar com maior intensidade sonora. Análise visual dos traçados mostram dados adicionais sobre a fisiologia do mecanismo da fonação, especialmente na região do esfíncter esofagiano superior.

Introduction: The SARS-CoV-2 virus is a positive-strand RNA virus. The virus can also be detected in many different specimens as throat swabs, nasal swabs, sputum, saliva, blood, etc. Objective: The aim of this paper is to compare the reliability of different types of specimen collection, saliva and swabs samples for the detection of SARS-CoV-2. Material and Methods: A sample of 22 COVID-19 positive patients was selected. Paired samples from saliva, nasopharyngeal, oropharyngeal and nasopharyngeal + oropharyngeal swabs were collected on the 7th day after diagnosis. The hyssops and medium employed was IMPROSWAB and IMPROVIRAL NAT Medium, Germany. The sample evaluation was conducted through RT-PCR. The results were compared using Fisher's exact test and ROC curve. The gold standard proposed in this paper was the nasopharyngeal + oropharyngeal swabs specimen. Results: The gold standard method detected 10 true positive cases, of which oropharyngeal swabs, nasopharyngeal swabs and saliva only detected three positive cases. Significant differences (Fisher's exact test p = 0.003) were detected in the comparison between saliva and the gold standart proposed. The ROC curve analysis showed that saliva had an area under the curve of 0.650, with a 30 percent of sensibility. However, the nasopharyngeal and nasopharyngeal + oropharyngeal samples had an area under curve of 0.950 and 1.000, respectively, with a sensibility of 90 percent and 100 percent, respectively. Conclusion: Saliva samples are not a reliable specimen for SARS-CoV-2 RNA detection. In turn, the most reliable specimens are nasopharyngeal and nasopharyngeal + oropharyngeal samples collected by swabbing(AU)
Introducción: El SARS-CoV-2 es un virus ARN positivo. Este virus puede ser detectado en diferentes tipos de secreción como hisopada bucal, nasal, esputo, saliva, sangre, etc. Objetivo: El objetivo de este estudio es comparar la confiabilidad de diferentes tipos de muestras, saliva y exudado, en la detección de SARS-CoV-2. Material y Métodos: Una muestra de 22 pacientes con diagnóstico de Covid-19 fue estudiada. Se tomaron muestras pareadas de saliva y exudado nasofaríngeo y orofaríngeo en cada paciente. Se emplearon los hisopos y medios de la firma alemana IMPROVE®. Los resultados de las determinaciones por RT-PCR se compararon mediante test de Fisher (test de la probabilidad exacta de Fisher) y cada sets de muestras fue evaluada individualmente y luego comparadas por curvas ROC. El estándar de oro propuesto fue el doble hisopado nasofaríngeo/orofaríngeo. Resultados: El método de oro propuesto detectó 10 casos positivos. La coincidencia de detección entre todos los sets de muestras fue de 3 casos (30 por ciento). Se obtuvieron diferencias significativas (Fisher p = 0.003) en la comparación de los casos detectados en saliva vs el estándar de oro. El análisis de curvas ROC mostró un área bajo la curva de 0.650 (30 por ciento de sensibilidad) para la saliva. En el caso del hisopado nasofaríngeo y el estándar de oro mostraron un área bajo la curva de 0.95 y 1.00, respectivamente, con una sensibilidad del 90 (AU) por ciento y 100 por ciento, respectivamente. Conclusiones: La saliva no es una muestra confiable para la detección de SARS-CoV-2. La muestra más confiable para el diagnóstico fue el hisopado nasofaríngeo y el doble hisopado(AU)
