RESUMO
INTRODUCTION: The aim of the study is to evaluate major causes of upper airway obstruction in newborns receiving healthcare at our institution, their method of endoscopic assessment and the rate of complications related to these procedures. MATERIALS AND METHODS: This is a case series study of patients from institutional neonatal intensive care unit (NICU) presenting signs of ventilatory dysfunction for whom an endoscopic airway assessment was warranted. Information of interest was collected from medical records according to a Clinical and Endoscopic Assessment Protocol created for the study. The protocol included clinical manifestations needing ENT evaluation, clinical signs of ventilatory dysfunction, comorbidities (pulmonary, cardiac, neurological, and gastrointestinal), examination method (airway endoscopy under general anesthesia or awake), exam complications, and final diagnosis. RESULTS: One hundred sixty-nine newborn patients who underwent airway endoscopy (awake bedside flexible fiberoptic laryngoscopy (FFL) or direct laryngoscopy and bronchoscopy (DLB) in the surgical ward) were included. Thirty-nine patients (23.07%) underwent bedside FFL. For the remaining 130 who underwent DLB under general anesthesia, the median procedure time was 30 min (20-44). Only 9 (5.32%) patients presented complications: desaturation (4), laryngospasm without desaturation with spontaneous resolution (2), apnea with resolution after stimulation (1), seizures (1), nasal bleeding (1). The most frequent diagnoses found were glossoptosis, posterior laryngeal edema, and laryngomalacia. CONCLUSION: This retrospective case series describes the prevalence of different pathologies that cause upper airway obstruction in neonates. Airway endoscopy seems an effective and safe diagnostic tool in neonatal airway obstruction. Glossoptosis was the most prevalent cause of obstruction in our center.

OBJECTIVES/HYPOTHESIS: Robin sequence (RS) consists of associated micrognathia, glossoptosis, and respiratory dysfunction, with or without cleft palate. Studies on how different patient characteristics impact the severity of respiratory dysfunction are scarce and contradictory; this study investigates how different features affect respiratory obstruction severity at diagnosis of RS in controlled analysis. STUDY DESIGN: Retrospective cohort study that enrolled 71 RS patients under 90 days old who received care in our institution from 2009 to 2020. METHODS: The primary outcome, respiratory dysfunction, was categorized into four severity groups and analyzed using a multinomial logistic regression model that considered age, sex, mandible length, cleft palate, syndromic diagnosis, other airway anomalies, and degree of glossoptosis. RESULTS: Mandible length, syndromic diagnosis, and Yellon grade 3 glossoptosis were related to poorer respiratory outcomes (need for respiratory support). In univariate analysis, for each additional 1 mm of mandible length at diagnosis, a mean reduction of 28% in the risk of needing respiratory support was observed (OR = 0.72; 0.58-0.89); syndromic diagnosis and grade 3 glossoptosis also raised the risk (OR = 6.50; 1.59-26.51 and OR = 12.75; 1.03-157.14, respectively). In multivariate analysis, only mandible length significantly maintained its effects (OR = 0.73; 0.56-0.96), a 27% reduction. CONCLUSIONS: Mandible length was an independent predictor for more severe respiratory dysfunction in RS patients, with larger mandibles showing protective effects. Syndromic diagnosis and Yellon grade 3 glossoptosis are also likely to be associated with poorer respiratory outcomes, although this was not demonstrated in multivariate analysis.

La secuencia de Pierre Robin (SPR) es una enfermedad rara, caracterizada por una tríada de malformaciones orofaciales como retrognatia, glosoptosis y fisura velopalatina media (paladar hendido); las cuales, generalmente provocan obstrucción de la vía aérea (OVA). La corrección de los defectos palatinos requiere en ocasiones varias intervenciones quirúrgicas, por esta razón el cuidado anestésico y abordaje de la vía aérea en forma adecuada, evita complica-ciones asociadas a esta enfermedad. Se presenta el caso de un paciente de 1 año y 20 días de edad, con antecedentes de vía aérea difícil, intentos fallidos de intubaciones preliminares e intervenido quirúrgicamente para corrección de paladar hendido, luego de una técnica combinada de intubación nasal con fibrobroncoscopio, desplazamiento de glosoptosis con ayuda de pala número 2 de videolaringoscopio (Glidescope®); manejo transoperatorio anestésico y proceso de extubación con excelentes resultados. Destacamos la importancia de realizar una adecuada planificación multidisciplinaria prequirúrgica con valoración exhaustiva de la vía aérea (VA) por laringoscopía directa o fibrobroncospia flexible para conocer el sitio exacto de la obstrucción y evitar desen-laces adversos.
Pierre Robin Sequence (PRS) is a rare disease characterized by a triad of orofacial malformations such as retrognathia, glossoptosis and velopalatine fissure (cleft palate). The malformations in PRS can lead into airway obstruction. The correction of the palatal defects sometimes requires several surgical interven-tions. Proper anesthetic care and a carefully planned approach to the airway can avoid complications associated with this disease. We present the case of a 1 year and 20 days old patient, with history of difficult airway, unsuccessful prior attempts of intubation, who underwent surgery to correct a cleft palate. We used a combined approach that included nasal intubation technique with a fiberoptic bronchoscope aided with a number 2 video laryngoscope blade (Gli-descope®) for displacement of the glossoptosys. Details of the intraoperative anesthetic management and subsequent successful extubation are provided. We highlight the importance of developing an adequate preoperative multidisciplinary plan of action, after a careful and detailed evaluation of the airway with direct laryngoscopy or fiberoptic bronchoscopy in order to identify the exact location of the obstruction and avoid adverse outcomes.

Introdução: Muitos pacientes portadores de sequência de Pierre Robin (micrognatia, glossoptose e obstrução de via aérea) apresentam o músculo genioglosso alterado, encurtado e retrátil, que impede a protração lingual, mantendo a parte anterior da língua verticalizada e seu volume deslocado em direção posterior. Isso pode corroborar para obstrução supraglótica, dificuldade alimentar e inversão das forças de estímulo do crescimento do corpo mandibular. Métodos: Estudo retrospectivo de pacientes com Pierre Robin tratados entre 2012 e 2017 pela equipe, com descrição da "ortoglossopelveplastia", que propõe uma modificação na glossopexia, soltando o genioglosso anômalo da sua inserção, liberando a língua para elevar seu terço anterior e avançar o volume de sua base, sendo auxiliada por ponto de tração da base lingual à sínfise mandibular. Apresentamos um algoritmo de tratamento proposto que prioriza a necessidade desta cirurgia, associada ou não à distração mandibular, de acordo com a gravidade da dificuldade respiratória e/ou alimentar. Resultados: São apresentados 12 casos de obstrução da orofaringe atendidos de 2012 a 2017, discutem-se suas prioridades, a ortoglossopelveplastia e se aplica o algoritmo proposto. Conclusão: A reorganização anatômica da musculatura em uma posição anteriorizada correta proporciona protração e funcionalidade à língua, com desobstrução da via aérea na orofaringe, melhora da função alimentar e do desenvolvimento mandibular, com baixa morbidade cirúrgica e poucas complicações.
Introduction: Several patients with the Pierre Robin sequence (micrognathia, glossoptosis, and airway obstruction) have an altered, shortened, and retractable genioglossus muscle that prevents protraction of the tongue and keeps the anterior part of the tongue vertical and its volume posteriorly displaced. This can contribute to supraglottic obstruction, feeding difficulty, and inversion of the growth stimulation forces of the mandibular body. Methods: A retrospective study of patients with the Pierre Robin sequence treated between 2012 and 2017 with "orthoglossopelveplasty," which includes modification of glossopexy, releasing the anomalous genioglossus of its insertion and releasing the tongue to raise its anterior third and advance the volume of its base using a traction suture of the tongue base to the mandible symphysis. We present a treatment algorithm that prioritizes the need for surgery associated, or not, with mandibular distraction in accordance with respiratory and/or feeding difficulty severity. Results: Twelve cases of oropharyngeal obstruction treated from 2012 to 2017 are presented, their priorities and orthoglossopleoplasty are discussed, and the proposed algorithm is applied. Conclusion: Anatomical reorganization of the musculature in a correct anterior position provides protraction and functionality to the tongue, clears the airway in the oropharynx, and improves the feeding function and mandibular development, with low surgical morbidity rates and few complications.

BACKGROUND: The Pierre Robin sequence (PRS) has been defined as the presence of micrognathia, glossoptosis, and respiratory obstruction in the neonatal period. Since its original description, different therapeutic approaches have been proposed obtaining different success rates, but there is no consensus about its management. METHODS: A literature review was conducted in PubMed, Embase, and Cochrane databases, for the period of January,1985 to November, 2016. A number of 23 articles resulting from clinical studies, discussing diagnostic tests or therapeutic approaches, and directly or indirectly comparing diagnostic or treatment modalities were selected and assessed using the GRADE methodology. RESULTS: After reviewing and analyzing the selected articles, an evidence-based algorithm for diagnosis and integral management of PRS patients was designed. CONCLUSION: Based on the anatomical principles and natural evolution of PRS, the clinical scenario must be evaluated thoroughly as a dynamic event to develop a management sequence that minimizes morbidity and mortality and accelerates patients' reinsertion to normal life.

OBJECTIVES/HYPOTHESIS: To assess the performance of endoscopic grading systems of glossoptosis in identifying severe clinical manifestations in children with Robin sequence (RS). STUDY DESIGN: Nested cohort cross-sectional study. METHODS: All RS patients diagnosed at Hospital Clinics of Porto Alegre from October 2012 to June 2016 were enrolled in this cohort. Patients underwent sleep endoscopy and were classified according to Yellon (Y) and de Sousa et al. (S) scales. Symptom severity evaluation was performed as defined by Cole et al. The outcome of interest was Cole's clinical classification grade 3. RESULTS: Eighty patients were eligible for analysis. Sensitivity (Y: 56.2%, S: 28.1%, P < .001) and specificity (Y: 85.4%, S: 93.8%, P = .038) in identifying severe clinical symptoms patients (i.e., Cole grade 3) were statistically different between Y and S classifications. A low but significant overall correlation was observed for both Y (rho = 0.372, P < .001) and S (rho = 0.439, P < .001) classifications when compared with Cole classification. Diagnostic odds ratio (DOR) for Y (DOR: 7.53, 95% confidence interval [CI]: 4.15-10.90) and S (DOR: 5.87, 95% CI: 1.86-9.87) were equivalent (P = .92). Also, receiver operating characteristic curves area under the curve were not significantly different between them. The positive likelihood ratio was 3.86 (95% CI: 1.82-8.16) and 4.50 (95% CI: 1.32-15.36) for Y and S, respectively. CONCLUSIONS: Y and S grading systems showed a low sensitivity and moderate to high specificity in detecting patients with severe clinical manifestations. Correlation between Y/S and Cole et al. grading were also considered low. Development of a more discriminative anatomic grading system is still needed for this specific disorder.

Abstract Introduction: Children may require tracheostomy due to many different health conditions. Over the last 40 years, indications of tracheostomy have endorsed substantial modifications. Objective: To evaluate pediatric patients warranted tracheostomy at our Hospital, in regard to their indications, associated comorbidities, complications and decannulation rates. Methods: Retrospective study concerning patients under 18 years of age undergoing tracheostomy in a tertiary health care center, from January 2006 to November 2015. Results: 123 children required a tracheostomy after ENT evaluation during the study period. A proportion of 63% was male, and 56% was under one year of age. Glossoptosis was the most common indication (30%), followed by subglottic stenosis (16%) and pharyngomalacia (11%). The mortality rate was 31%. By the end of this review, 35 children (28.4%) had been decannulated, and the fewer the number of comorbidities, the greater the decannulation rate (0.77 ± 0.84 vs. 1.7 ± 1.00 comorbidities; p < 0.001). Conclusion: Tracheostomy in children is a relatively frequent procedure at our hospital. The most common indications are glossoptosis and subglottic stenosis. A high mortality rate was found, potentially substantiated by the high number of critical care patients with chronic neurological conditions in this cohort. Our decannulation rate is slightly below other series, probably because of the greater amount of patients with comorbidities.
Resumo Introdução: As crianças podem necessitar de traqueostomia devido a diferentes problemas de saúde. Ao longo dos últimos 40 anos, as indicações de traqueostomia passaram por mudanças substanciais. Objetivo: Avaliar pacientes pediátricos com traqueostomia no nosso hospital, no que diz respeito às suas indicações, comorbidades associadas, complicações e taxas de decanulação. Método: Estudo retrospectivo de pacientes com menos de 18 anos submetidos a traqueostomia em um centro de saúde terciário, de janeiro de 2006 a novembro de 2015. Resultados: 123 crianças precisaram de uma traqueostomia após avaliação otorrinolaringológica durante o período do estudo. Do total, 63% eram do sexo masculino e 56% menores de um ano. Glossoptose foi a indicação mais comum (30%), seguida por estenose subglótica (16%) e faringomalácia (11%). A taxa de mortalidade foi de 31%. Até o fim deste artigo, 35 crianças (28,4%) haviam sido decanuladas e quanto menor o número de comorbidades, maior foi a taxa de decanulação (0,77 ± 0,84 vs. 1,7 ± 1,00 comorbidades; p < 0,001). Conclusão: A traqueostomia em crianças é um procedimento relativamente frequente em nosso hospital. As indicações mais comuns são glossoptose e estenose subglótica. Uma alta taxa de mortalidade foi encontrada, potencialmente comprovada pelo elevado número de pacientes críticos com condições neurológicas crônicas nessa coorte. Nossa taxa de decanulação está ligeiramente abaixo de outras séries, provavelmente por causa da maior quantidade de pacientes com comorbidades.

OBJECTIVE: To investigate the accuracy of clinical evaluation of swallowing in a sample of children with laryngomalacia or glossoptosis and describe the prevalence of dysphagia in each of these diseases, as well as characterize the swallow response to speech and language therapy interventions. STUDY DESIGN: Children aged 1 month to 11 years receiving care at the Department of Otolaryngology, Hospital de Clínicas de Porto Alegre, Brazil, were evaluated in a cross-sectional design. Evaluation of swallowing was performed at two time points by two blinded speech-language pathologists, one responsible for clinical evaluation and the other for videofluoroscopic study. The protocols employed were based on the instruments proposed by DeMatteo et al. (DeMatteo C, Matovich D, Hjartarson A. Comparison of clinical and videofluoroscopic evaluation of children with feeding and swallowing difficulties. Dev Med Child Neurol 2005;47:149-157.). RESULTS: The study sample consisted of 29 patients: 10 patients with laryngomalacia and 19 patients with glossoptosis. The sensitivity of clinical evaluation did not exceed 50% in any of the evaluations, but specificity reached 100% in some cases, using thickened liquids. The prevalence of dysphagia was 100%, and the use of thickened liquids significantly reduced tracheal aspiration. CONCLUSIONS: Dysphagia was highly prevalent in this sample. The sensitivity of clinical evaluation to detect laryngeal penetration and tracheal aspiration was low, as the majority of aspiration events were silent. The videofluoroscopic study is important in order to determine a safest method to feed the patient. Pediatr Pulmonol. 2017;52:41-47. © 2016 Wiley Periodicals, Inc.

PURPOSE: Genial tubercles (GTs) are bony protuberances on the lingual aspect of the mandible symphysis, where genioglossus and geniohyoid muscles are inserted. In the literature, few papers report their real dimensions. Cleft lip and palate are craniofacial anomalies involving the maxilla, but the anatomical structures of the mandible can be altered when these have associated with the cleft, some syndrome. This study aimed to evaluate the GTs of 30 individuals and to make their measurements in cone beam computed tomography examinations. METHODS: A sample of 30 individuals, 19 of them with cleft lip and palate, 6 individuals with Treacher Collins syndrome (TCS), and 5 individuals with Pierre Robin sequence, was used. The GTs were evaluated about the amount and the following measurements were performed: A--distance from the apex of the central incisors to GT, B--mandibular thickness in the region of GT, C-GT height, D-GT width, and E--distance from inferior border of mandible to GT. RESULTS: The individuals presented since the absence of GTs to 3. The TCS group had the highest average of the measurements A, D, and E with statistical difference (P = 0.006) (P = 0.011) and (P = 0.017), respectively. The Pierre Robin sequence group had the highest average measurement of B and C, but there was no statistical difference. CONCLUSIONS: The difference in the measurements can be explained perhaps because individuals with TCS have glossoptosis and changes on retrognathic mandible, which would affect the position of the GT.
