Changes in the Craniomaxillofacial Growth and Development of Sprague Dawley Rats Subjected to Permanent Experimental Unilateral Nasal Obstruction / Cambios en el Crecimiento y Desarrollo Cráneo Maxilo Facial de Ratas Sprague Dawley Sometidas a Obstrucción Nasal Unilateral Experimental Permanente

SUMMARY: Breathing is considered a vital function dependent on factors such as adequate permeability of the nasal route, which is linked to physiological functions, intellectual processes, and craniofacial growth. The aim of this study was to determine the changes in the craniomaxillofacial growth and bone development of Sprague Dawley rats subjected to permanent experimental unilateral nasal obstruction. Twenty-four newborn rats were used, randomized, and divided into experimental and control groups. The right nostril was obstructed, and weight, length, and Lee's index measurements were recorded at 8 and 16 weeks. Craniomandibular x-rays were taken of each animal, obtaining linear neuro- and viscerocranial measurements. Then, a biochemical analysis was performed to measure the alkaline phosphatase concentration. The results were analyzed in the SPSS software, performing a descriptive analysis, using a t-test for independent samples, comparing basal, cephalometric, and biochemical characteristics between the control and experimental groups, considering a significance range of 5%. When comparing the experimental and control groups, the variables length, weight, and Lee's index presented no significant differences. In the x-ray analysis, at 8 weeks, the Co-L1 and Co-Mn measurements were reduced, whereas the Ba-So increased, with significant differences. At 16 weeks, the L1-O, Po-Ba, and E-Mu measurements decreased; however, Co-Gn registered a greater value with significant differences. The alkaline phosphatase levels fell significantly at week 16 in the experimental group. In conclusion, the reduction of permanent nasal respiratory flow is related to modifications in facial growth at 8 and 16 weeks and to the reduction of alkaline phosphatases at 16 weeks.

La respiración se considera una función vital, dependiente de factores como la permeabilidad adecuada de la vía nasal, vinculada con funciones fisiológicas, procesos intelectuales y crecimiento cráneofacial. El objetivo de este estudio fue determinar los cambios en el crecimiento y desarrollo óseo cráneo maxilo facial de ratas Sprague Dawley sometidas a obstrucción nasal unilateral experimental permanente. Se utilizaron 24 ratas macho neonatas, randomizadas y divididas en grupo control y experimental. Fue realizada obstrucción nasal de la narina derecha y realizadas mediciones de peso, longitud e índice de Lee a las 8 y 16 semanas. Se efectuaron radiografías cráneomandibulares a cada animal, obteniendo medidas lineales de neuro y viscerocráneo. Posteriormente se realizó análisis bioquímico, para medir la concentración de fosfatasa alcalina. Los resultados fueron analizados en el software SPSS, realizándose análisis descriptivo, empleando prueba T para muestras independientes comparando características basales, cefalométricas y bioquímicas entre los grupos control y experimental, considerando un umbral de significancia de 5 %. Al comparar los grupos control y experimental, las variables longitud, peso e índice de Lee no presentaron diferencias significativas. En el análisis radiográfico, a las 8 semanas, las medidas Co-L1 y Co-Mn presentaron reducción, mientras que Ba-So aumentó, con diferencias significativas. A las 16 semanas, las medidas L1-O, Po-Ba y E-Mu disminuyeron, sin embargo, Co-Gn registró un mayor valor, con diferencias significativas. Los niveles de fosfatasa alcalina disminuyeron significativamente en la semana 16 en el grupo experimental. En conclusión, la reducción de flujo respiratorio nasal permanente se relaciona con modificaciones del crecimiento facial a las 8 y 16 semanas y con la reducción de ALK en análisis a las 16 semanas.

Improvement in Nasal Obstruction and Quality of Life after Nasal Septoplasty with Turbinoplasty: A Pre- and Post-study

Abstract Introduction Septoplasty and turbinoplasty are common surgical interventions used to relieve nasal obstructive symptoms. Since it is difficult to measure the degree of nasal blockage, current literature wonders about the frequent performance of these procedures. Objective To evaluate the perceived change in the nasal obstruction and the quality of life (QoL) of patients that underwent a septoplasty along with a turbinoplasty by applying subjective scales, to describe the correlation between those scales, and to study the impact of clinical factors in the postoperative outcomes. Methods Prospective observational study. The Nasal Obstruction Symptom Evaluation (NOSE), the Visual Analog Scale (VAS), and the Glasgow Benefit Inventory (GBI) were assessed. The paired sample Wilcoxon test was used to evaluate the difference between the pre- and postoperative surveys. The correlation coefficient between the subjective scales was calculated. A quantile regression was performed to evaluate the effect of surgery on the results adjusted for clinical and demographic variables. Results A total of 115 patients were interviewed. Postoperative NOSE scores were 45 points lower (95% confidence interval [CI]: - 53.53-- 35.46; p < 0.001) in comparison with the NOSE preoperative scores. Obesity was the only statistically significant factor associated with worse outcomes. Additionally, we found a high correlation between the NOSE and VAS scores and a negative correlation between the GBI and postoperative VAS scores. Conclusion Nasal septoplasty, when paired with a turbinoplasty, decreases nasal obstruction and improves QoL. Obesity was associated with worse results. There was a strong correlation between the NOSE and the VAS results and between the GBI and postoperative VAS results.

Cirugía de cornetes inferiores en población pediátrica: ¿Cómo, cuándo y por qué?

La hipertrofia de cornetes inferiores representa una de las principales causas de obstrucción nasal en pacientes pediátricos. En estudios recientes se ha observado un aumento significativo de esta patología en niños que no responden a terapia médica. La evidencia disponible recomienda la cirugía como tratamiento de elección en la obstrucción nasal refractaria en niños con cornetes hipertróficos. Sin embargo, hasta la fecha no existen criterios formales de derivación a cirugía en la población pediátrica y los estudios en infantes son limitados. Al mismo tiempo, la falta de consenso no ha permitido recomendar una técnica quirúrgica en estos pacientes por sobre otras. Por lo tanto, se hace necesario profundizar las diferentes alternativas disponibles, considerando y optando por aquellas que presenten mayores beneficios y menor riesgo de complicaciones. En la presente revisión se estudió la evidencia disponible hasta el momento sobre este tema en la población pediátrica y además se realizó un análisis de la efectividad y complicaciones de las diferentes técnicas disponibles.

Inferior turbinate hypertrophy represents one of the leading causes of nasal obstruction in pediatric patients. Recent studies have observed a significant increase in turbinate hypertrophy in children that does not respond to medical treatment. The latest evidence recommends inferior turbinoplasty for treating nasal obstruction in children with hypertrophic turbinates. However, until today there are no formal criteria for referral to surgery in the pediatric population, and studies in children are limited. At the same time, the absence of consensus has not allowed the recommendation of one surgical technique over others in these patients. This is why it is necessary to deepen the available alternatives and choose those with more significant benefits and a lower risk of complications. In this review, we study available evidence about this topic in the pediatric population and analyze the effectiveness and complications of different known techniques.

Influence des facteurs épidémio-cliniques dans le résultat fonctionnel de la septoplastie: étude de 250 cas / Epidemiological and clinical predictive factors of success in septoplasty: Study of 250 patients

to describe the epidemiological and clinical aspects, to evaluate the surgical result and to identify the prognostic factors for the success of septoplasty. Methods: It was a retrospective study including 250 patients operated on for a septoplasty collected over a 6-yearperiod. The evaluation of our results was made using 2 tools: NOSE scale and the visual satisfaction scale. Results: In our series, there was a male predominance with a sex ratio of 1.4. The mean age of the patients was 32.7 years. The medical history was dominated by allergic rhinitis in 38.4% of cases. Nasal trauma was noted in 45.2% of cases. A subjective quantification of respiratory discomfort by the NOSE score made it possible to divide them into 3 groups:Group 1: Severe ON: 65.2% of cases; Group 2: Moderate ON: 31.6% of cases; Group 3: Mild ON: 3.2% of cases. Our analytical study of the epidemiological and clinical factors that may influence the functional results showed that: Severe or moderate overall discomfort, severe ON (NOSE scale> 50) or moderate (NOSE scale between 26 and 50), DS classified zone I, II, III according to the Cottle classification, a quasi-obstructive deviation were considered as a predictor of the success of septoplasty. Conclusion: Several factors can influence the results of a septoplasty that must be considered before any surgical indication.

Relationship between nasal septum morphology and nasal obstruction symptom severity: computed tomography study / Relação entre a morfologia do septo nasal e a gravidade dos sintomas de obstrução nasal: estudo de tomografia computadorizada

Abstract Introduction The impact of the nasal septum morphology on the severity of obstruction symptoms has not been fully explored. Objective This study aimed to investigate whether the morphology of the deviated nasal septum assessed by computed tomography may explain nasal obstruction severity. Methods The study included 386 patients who were referred to the computed tomography examination of the paranasal sinuses. Patient selection criteria were the absence of facial anomalies, facial trauma, nasal surgery, and sinonasal tumors. Computed tomography images were used to estimate deviated nasal septum prevalence, the prevalence of Mladina's seven types of deviated nasal septum, and to measure the deviated nasal septum angle. Nasal obstruction severity was assessed by the nasal obstruction symptom evaluation, NOSE scale. The relationship between NOSE score, deviated nasal septum morphology, and deviated nasal septum angle was performed by a statistical regression model on the reduced sample of 225 patients. Results The prevalence of deviated nasal septum was 92.7%. Type 7 deviated nasal septum was the most frequent (34.2%) followed by type 5 (26.2%) and type 3 (23.6%). The worst NOSE scores were recorded in the type 2 deviated nasal septum (45.00 ± 28.28). The mean deviated nasal septum angle in patients with nasal obstruction was 8.5° ± 3.24. NOSE scores were not significantly associated with deviated nasal septum types and angles. Conclusion Patients with different types of deviated nasal septum have different NOSE scores. Computed tomography morphology of the deviated nasal septum could not fully explain the severity of nasal obstruction.

Resumo Introdução O impacto da morfologia do septo nasal na gravidade dos sintomas obstrutivos nasais ainda não foi totalmente explorado. Objetivo Investigar se a morfologia do desvio do septo nasal avaliada pela tomografia computadorizada pode explicar a gravidade da obstrução nasal. Método O estudo incluiu 386 pacientes encaminhados para exame tomográfico de seios paranasais. Os critérios de seleção dos pacientes foram: ausência de anomalias faciais, trauma facial, cirurgia nasal e tumores nasossinusais. Imagens de tomografia computadorizada foram usadas para estimar a prevalência de desvios do septo nasal, a prevalência dos sete tipos de desvios do septo nasal de Mladina e para medir o ângulo do desvio septal. A gravidade da obstrução nasal foi avaliada pela escala Nasal Obstruction Symptom Evaluation, NOSE. A relação entre o escore da NOSE, a morfologia e o ângulo do desvio septal foi verificada por um modelo de regressão estatística em uma amostra reduzida de 225 pacientes. Resultados A prevalência de desvios do septo nasal foi de 92,7%. O desvio septal do tipo 7 foi o mais frequente (34,2%), seguido do tipo 5 (26,2%) e do tipo 3 (23,6%). Os piores escores da escala NOSE foram registrados nos desvios septais tipo 2 (45,00 ± 28,28). O ângulo médio do desvio em pacientes com obstrução nasal foi de 8,5° ± 3,24. Os escores da escala NOSE não foram significativamente associados aos tipos e ângulos do desvio septal. Conclusão Pacientes com tipos diferentes de desvios do septo nasal apresentam diferentes escores na escala NOSE. A morfologia do desvio septal à tomografia computadorizada não conseguiu explicar totalmente a gravidade da obstrução nasal.

Avaliação da Obstrução Nasal em Pacientes Submetidos à Septoplastia com Cirurgia das Conchas Nasais Inferiores Utilizando o Questionário NOSE / Evaluation of Nasal Obstruction in Patients Undergoing Septoplasty with Inferior Nasal Turbinate Surgery Using the NOSE Questionnaire

Introdução: O desvio septal e a hipertrofia das conchas nasais inferiores são as principais causas de obstrução nasal. Uma forma de avaliarmos o grau de obstrução nasal é através do questionário NOSE, o qual é baseado em cinco perguntas com nota de 0 a 04, podendo alcançar 100 pontos. Esse pode ser aplicado no pré-operatório e pós-operatório, servindo para comparação do grau de melhora do paciente em relação à obstrução nasal. Objetivo: O trabalho teve como objetivo aplicar o questionário NOSE para avaliação de grau de satisfação dos pacientes no pós-operatório de cirurgia de septoplastia, associado à técnica cirúrgica das conchas nasais inferiores. Métodos: Os pacientes eletivos para septoplastia e cirurgia das conchas nasais inferiores foram avaliados com o questionário NOSE no pré-operatório e no pós-operatório (07 e 30 dias, 3 e 06 meses e 01 ano). Para análise estatística, foi utilizado o teste de Friedman e de Mann-Whitney. Foram excluídos os pacientes menores de idade e presença de alterações sinusais. Resultados: Um total de 64 pacientes preencheu os critérios de inclusão, sendo excluídos 13 pacientes por perda de seguimento, permanecendo com 51 pacientes. A média de idade foi de 31,33 anos. A maioria dos pacientes era do gênero masculino, 72,5%, e 27,5% do gênero feminino. Houve diferença estatística entre o pré-operatório e o seguimento de 06 meses e 01 ano. Conclusão: O questionário NOSE mostrou que a septoplastia associada à cirurgia das conchas nasais inferiores demonstrou melhora do sintoma de obstrução nasal no pós-operatório, tendo como parâmetro o próprio paciente.

Introduction: Septal deviation and inferior nasal turbinate hypertrophy are the primary causes of nasal obstruction. One way to assess the degree of nasal obstruction is through the NOSE questionnaire, which bases itself on five questions with a score from 0 to 04, and may reach 100 points. Its application can be preoperatively and postoperatively to compare the degree of patient improvement regarding nasal obstruction. Objective: This study aimed to apply the NOSE questionnaire to evaluate the degree of patient satisfaction in the post-operative period of septoplasty associated with the surgical technique of inferior nasal concha. Methods: Elective patients for septoplasty and inferior nasal concha surgery were evaluated with the NOSE questionnaire preoperatively and postoperatively (7 and 30 days, 3 and 6 months, and one year). The Friedman and Mann-Whitney tests were used for statistical analysis. Exclusion of underage patients and the presence of sinus changes. Results: A total of 64 patients met the inclusion criteria, eliminating 13 patients due to loss of follow-up, remaining only 51 cases. The mean age was 31.33 years. Most patients were male, 72.5% and 27.5% were female. There was a statistical difference between the preoperative and the follow-up of 6 months and one year. Conclusion: The NOSE questionnaire showed that septoplasty associated with inferior nasal concha surgery showed improvement of nasal obstruction symptoms postoperatively, using the patient's parameters.

Overall quality of life impact on candidates for septorhinoplasty according to the World Health Organization quality of life brief questionnaire (WHOQOL-Brief) / Impacto geral na qualidade de vida em candidatos à septorrinoplastia de acordo com o World Health Organization Quality of Life Brief Questionnaire (WHOQOL-Brief)

Abstract Introduction: Quality of life has been an increasingly reference measure in whole health impact of diseases and in septorhinoplasty evaluation as well. It is known that the decision for this elective surgical procedure requires the subjective perception of patients' complaints about their own health and life stage in association with the surgeon's aesthetic and functional perspective of each case. Objective: To define the quality of life of candidates for septorhinoplasty using the World Health Organization quality of life questionnaire, WHOQOL-Brief, and the prevalence of other independent variables for this population. Methods: A cross-sectional study using a sample of candidates for septorhinoplasty was performed. All patients responded to the WHOQOL-Brief during the pre-operative period. A normative population quality of life study was the reference for the sample size and means. Results: A total of 302 patients were included among the 322 eligible patients. Twenty patients did not complete the questionnaire correctly and were excluded from the study. The sample consisted of patients aged between 15 and 78 years (34.7±14 years): the most majority were Caucasian and female. Among this group, 88.1% declared symptoms of nasal obstruction and 77.4% complained of sleeping problems. It was seen that 10.9% patients chose the surgery primarily for aesthetic improvement; 37.1% chose it mainly because of functional symptoms and 52% chose it for both functional and aesthetic reasons. The physical health domain's mean was 62.2 ± 17), which is a higher mean compared to the references' standard one (Μ = 58.9± 10.5, p = 0.002). The social relationship domain mean was 70.8±18.1; that is a lower mean then general population's one (Μ = 76.2± 18.8, p < 0.001). The psychological and the environment domain means revealed no difference when comparing the sample to the norm (μ = 65.3 ±15.1 vs. μ = 65.9 ±10.8, p = 0.530 and μ = 60.3 ±13.1 vs. μ = 59.9 ± 14.9, p = 0.667). Conclusion: The WHOQOL-Brief questionnaire proved an accurate instrument to cross-check different populations in quality of life outcomes. The study provides good evidence of lower quality of life in social relations domain and high prevalence of nasal obstruction and sleeping symptoms in candidates for septorhinoplasty. This study contributes to recent literature with relevant data supporting a more integrative evaluation in this population in the preoperative period. The results may also encourage a multidisciplinary approach for chronic symptoms when associated with nasal obstruction, sleep disorders and aesthetic complaints.

Resumo Introdução: A qualidade de vida tem sido cada vez mais uma medida de referência no impacto total das doenças na saúde e também na avaliação da septorrinoplastia. Sabe-se que a decisão por esse procedimento médico eletivo requer a percepção subjetiva da queixa do paciente sobre sua própria saúde e estágio de vida em associação com a perspectiva estética e funcional do cirurgião de cada caso. Objetivo: Definir a qualidade de vida de pacientes candidatos à septorrinoplastia por meio do questionário de qualidade de vida da OMS, WHOQOL-Brief e a prevalência de outras variáveis independentes para essa população. Método: Foi feito um estudo transversal com uma amostra de candidatos à septorrinoplastia. Todos os pacientes responderam ao WHOQOL-Brief no momento pré-operatório. Um estudo normativo de qualidade de vida populacional foi a referência para o tamanho e as médias da amostra. Resultados: Foram incluídos 302 pacientes entre os 322 elegíveis. Vinte pacientes não preencheram o questionário corretamente e foram excluídos do estudo. A amostra foi composta por pacientes entre 15 e 78 anos (34,7 ± 14 anos) e a maioria era branca e do sexo feminino. Entre todos, 88,1% declararam sintomas de obstrução nasal e 77,4% declararam ter sintomas durante o sono. Observou-se que 10,9% dos pacientes optaram pela cirurgia principalmente para melhoria estética; 37,1% optaram principalmente devido a sintomas funcionais e 52% optaram por queixa funcional e estética. A média do domínio saúde física foi de 62,2 ± 17, uma média mais alta em comparação com o padrão de referências (μ = 58,9 ± 10,5, p = 0,002). A média do domínio do relacionamento social foi de 70,8 ±18,1, uma média inferior à da população geral (μ = 76,2 ± 18,8, p < 0,001). As médias dos domínios psicológico e meio ambiente não diferiram na comparação da amostra com o normativo (μ = 65,3 ±15,1 vs. μ = 65,9 ± 10,8, p = 0,530 e μ = 60,3 ±13,1 vs. μ = 59,9 ± 14,9, p = 0,667). Conclusão: O questionário WHOQOL-Brief demonstrou servir como um instrumento preciso para cruzar diferentes populações nos desfechos de qualidade de vida. O estudo fornece boas evidências de menor qualidade de vida no domínio relações sociais e alta prevalência de obstrução nasal e sintomas durante o sono em candidatos à septorrinoplastia. Este estudo contribui para a literatura recente com dados relevantes que subsidiam uma avaliação mais integrativa nessa população no momento pré-operatório. Os resultados também podem incentivar uma abordagem multidisciplinar para os sintomas crônicos quando associados, como ocorre na obstrução nasal, distúrbios do sono e queixas estéticas.

The Effect of Turbinate Injection of Botulinum Toxin A on the Symptoms of Idiopathic Rhinitis

Abstract Introduction Idiopathic rhinitis is a nonallergic and noninfectious rhinitis characterized mainly by nasal obstruction and rhinorrhea, resulting from an autonomic imbalance. Botulinum toxin type A (BTX-A) demonstrated its action in reducing rhinorrhea and nasal obstruction when injected into the nasal turbinates or septum. Objective To analyze the effects of intranasal BTX-A injection to control the symptoms of idiopathic rhinitis and its possible adverse effects. Method Patients with idiopathic rhinitis were divided into two groups. Group A had 15 participants (8 female and 6 male), of ages from 47 to 84 years (mean 66.57 years), and these received 60 U of Dysport (Ipsen Ltd, Maidenhead, Berkshire, UK) in each inferior nasal turbinate; group B had 12 participants (1 male and 11 female), of ages from 50 to 76 years (mean 60 years), and they received 1 ml of 0.9% saline. The individuals were reevaluated in the 1st, 2nd, 4th, 8th, and 12th weeks after injection by a questionnaire, accompanied by nasal inspiratory peak flow and acoustic rhinometry. Results Group A showed significant improvement, mainly regarding the symptoms of sneezing/itching and nasal obstruction, over time and when compared to group B. Acoustic rhinometry confirmed the improvement in nasal obstruction. There was no relationship between the nasal peak flow data and the nasal obstruction score. No major adverse effects have been reported. Conclusion The injection of botulinum toxin in the inferior nasal turbinates of patients with idiopathic rhinitis reduces the symptoms of sneezing, itching, nasal obstruction, and runny nose without significant adverse effects, suggesting that it is an option in the treatment of these patients.

Posicionamento ideal das cartilagens laterais inferiores associado à otimização da válvula nasal externa / Ideal positioning of the lower lateral cartilages associated with the optimization of the external nasal valve

Introdução: O posicionamento das Cartilagens Laterais Inferiores (CLI) está diretamente relacionado à boa funcionalidade nasal. Quando essas cartilagens apresentam um mau posicionamento cefálico, a parede lateral da válvula nasal externa fica sem suporte adequado, podendo levar à insuficiência valvular. O objetivo é definir qual o posicionamento anatômico ideal das CLI associado à otimização da válvula nasal externa. Métodos: Revisão de literatura narrativa nas seguintes bases de dados: SciELO, LILACS e Medline. Os descritores utilizados foram: "cartilagens nasais"; "obstrução nasal" e "rinoplastia", sendo selecionados 15 artigos essenciais para o entendimento do assunto. Revisão de literatura: O posicionamento do ramo lateral das CLI forma o contorno da ponta nasal e dá estabilidade à parede lateral da válvula nasal externa. Constantian definiu que o posicionamento ideal do ramo lateral das CLI à margem da asa nasal deve ser 45° ou menos. Para Toriumi, o ângulo é mensurado a partir do ramo lateral das CLI em relação ao plano sagital mediano e o valor adequado é de aproximadamente 45°. Para Silva, o posicionamento das CLI é mensurado pelo ângulo de divergência entre as CLI e tem como valor apropriado aproximadamente 90°. Conclusão: A válvula nasal externa apresenta melhor funcionamento quando as CLI estão bem posicionadas, a saber: o ângulo formado entre a borda lateral das CLI e a margem alar é próximo de 45° ou menos; o ângulo formado entre as CLI e o plano sagital mediano é próximo de 45°; o ângulo de divergência formado entre as CLI é próximo a 90°.

Introduction: The Lower Lateral Cartilages (LLC) positioning is directly related to good nasal functionality. When these cartilages have cephalic malpositioning, the lateral wall of the external nasal valve is not adequately supported, which can lead to valvular insufficiency. The objective is to define the ideal anatomical positioning of the LLC associated with optimizing the external nasal valve. Methods: Review narrative literature in the following databases: SciELO, LILACS and Medline. The descriptors used were: "nasal cartilages,"; "nasal obstruction," and "rhinoplasty," being selected 15 essential articles for the understanding of the subject. Literature review: Positioning the lateral crura of the LLC forms the contour of the nasal tip and provides stability to the lateral wall of the external nasal valve. Constantian defined the ideal positioning of the lateral crura of the LLC at the margin of the nasal alae should be 45° or less. For Toriumi, the angle is measured from the lateral crura of the LLC concerning the midsagittal plane, and the appropriate value is approximately 45°. For Silva, the positioning of the LLC is measured by the angle of divergence between the LLCs, and its appropriate value is approximately 90°. Conclusion: The external nasal valve works better when the LLCs are well-positioned, namely: the angle formed between the lateral edge of the LLCs and the alar margin is close to 45° or less; the angle formed between the LLC and the midsagittal plane is close to 45°; the divergence angle formed between the LLC is close to 90°.

How obesity affects nasal function in obstructive sleep apnea: anatomic and volumetric parameters / Como a obesidade afeta a função nasal na apneia obstrutiva do sono: parâmetros anatômicos e volumétricos,

Abstract Introduction Obstructive sleep apnea is a consequence of upper airway collapse. Any obstructive sector in the upper airway can contribute to pharyngeal collapse. Obesity and obesity-related disorders play an important role in obstructive sleep apnea and its relationship with increased upper airway resistance. Objective This study was designed to evaluate the relationship between obesity and properties of the nasal cavity in patients with obstructive sleep apnea. Methods The study was conducted retrospectively by review of medical records of adult patients. The nasal obstruction symptom evaluation, NOSE instrument, was used to measure nasal obstruction. Sleep breathing disorders were evaluated by polysomnography exams. Nasal volume was obtained by computed tomography scans and volumetric reconstruction of nasal airway. Nasal anatomic alterations were assessed by nasal endoscopy. Results Analysis of 83 patient records, among whom 54 were male and 29 females, found the mean body mass index of 28.69 kg/m2. Obese and non-obese groups were determined by using cut-off 30 kg/m2. In the comparison between groups, the obese group had a positive and significant correlation with apnea/hypopnea index (p= 0.02), NOSE instrument (p= 0.033) and inferior turbinate hypertrophy (p= 0.036), with odds ratio 1.983 (95% IC 1.048 − 3.753). nasal septum deviation (p= 0.126) and nasal airway volume evaluation (p= 0.177) showed no significant results. Conclusion Obesity was significantly correlated with subjective nasal obstruction, NOSE scale, and inferior turbinate hypertrophy in patients with obstructive sleep apnea. There was no correlation with the nasal volume evaluation. Level of Evidence 3b - Individual case-control study.

Resumo Introdução A apneia obstrutiva do sono é consequência do colapso das vias aéreas superiores Qualquer região de obstrução nas vias aéreas superiores pode contribuir para o colapso da faringe. A obesidade e os distúrbios relacionados à obesidade desempenham um papel importante na apneia obstrutiva do sono e sua relação com o aumento da resistência das vias aéreas superiores. Objetivo Avaliar a relação entre a obesidade e as propriedades da cavidade nasal em pacientes com apneia obstrutiva do sono. Método O estudo foi feito retrospectivamente através da revisão de prontuários médicos de pacientes adultos. O instrumento de avaliação NOSE, do inglês nasal obstruction symptom evaluation, foi usado para avaliar a obstrução nasal. Os distúrbios respiratórios do sono foram avaliados através de exames polissonográficos. O volume nasal foi obtido por tomografia computadorizada e a reconstrução volumétrica das vias aéreas nasais. As alterações anatômicas nasais foram avaliadas por endoscopia nasal. Resultados A análise dos prontuários de 83 pacientes, entre os quais 54 eram do sexo masculino e 29 do feminino, encontrou um índice de massa corporal médio de 28,69 kg/m2. Os grupos obeso e não obeso foram determinados com o ponto de corte de 30 kg/m2. Na comparação entre os grupos, o grupo obeso apresentou correlação positiva e significante com o índice de apneia/hipopneia (p = 0,02), instrumento NOSE (p = 0,033) e hipertrofia da concha inferior (p = 0,036), com uma odds ratio de 1,983 (IC95%: 1,048 a 3,753). A avaliação do desvio do septo nasal (p = 0,126) e do volume das vias aéreas nasais (p = 0,177) não mostrou resultados significantes. Conclusão A obesidade correlacionou-se significantemente com a obstrução nasal subjetiva pela escala NOSE e hipertrofia de concha inferior em pacientes com apneia obstrutiva do sono. Não houve correlação com a avaliação do volume nasal. Nível de evidência 3b. Estudo de caso-controle individual.

Are reduced internal nasal dimensions a risk factor for obstructive sleep apnea syndrome? / Dimensões internas nasais reduzidas constituem fator de risco para síndrome da apneia obstrutiva do sono?

Abstract Introduction Obstructive sleep apnea syndrome is a high-prevalence disorder found in the population. Studies have shown a possible association between nasal obstruction and obstructive sleep apnea syndrome, but the existence of a association between the degree of nasal obstruction and obstructive sleep apnea syndrome severity has not yet been proven. Objective To evaluate the internal nasal dimensions of adults with primary snoring and obstructive sleep apnea syndrome by acoustic rhinometry and to correlate the findings with obstructive sleep apnea severity. Methods Twenty-one male Caucasian subjects with complaints of snoring and/or respiratory pauses during sleep, aged between 18 and 60 years of age, were evaluated. After clinical evaluation, otorhinolaryngological examination and flexible nasopharyngolaryngoscopy, all patients underwent type III polysomnography. The participants were divided into two groups according to symptom severity: group 1, primary snoring and/or mild obstructive sleep apnea syndrome(n = 9) and group 2, moderate/severe obstructive sleep apnea syndrome (n = 12). Internal nasal dimensions were measured by acoustic rhinometry, analyzing minimum cross sectional area (CSA) and three nasal segment volumes. Results The respiratory event index corresponded to 8.1 ± 4.0 in group 1 and 47.5 ± 19.1 in group 2. In group 1, the cross-sectional areas values, in cm2, corresponded to: CSA 1 = 1.1 ± 0.4; CSA 2 = 2.1 ± 0.9; CSA 3 = 3.5 ± 1.8 and, in group 2: CSA 1 = 1.2 ± 0.3, CSA 2 = 2.0 ± 0.5; CSA 3 = 2.8 ± 0.7. In group 1, volumes (V), in cm3, corresponded to: V1 = 3.5 ± 1.0; V2 = 9.3 ± 5.0; V3 = 40.2 ± 21.5 and in group 2 a: V1 = 3.6 ± 0.5; V2 = 7.6 ± 1.5; V3 = 31.5 ± 6.7. Cross-sectional area and volume ​​did not differ between groups. Conclusion There were no significant differences in the cross-sectional areas and nasal volumes between individuals with primary snoring-mild obstructive sleep apnea syndrome and moderate-severe obstructive sleep apnea syndrome. Differently to the raised hypothesis, our results suggest that there is no association between internal nasal dimensions and severity of obstructive sleep apnea syndrome.

Resumo Introdução A síndrome da apneia obstrutiva do sono é uma desordem de elevada prevalência na população. Estudos constataram possível associação entre obstrução nasal e síndrome da apneia obstrutiva do sono, porém a existência de uma relação entre a intensidade da obstrução nasal e a gravidade da síndrome da apneia obstrutiva do sono ainda não foi comprovada. Objetivo Avaliar as dimensões internas nasais de adultos com ronco primário e síndrome da apneia obstrutiva do sono por meio de rinometria acústica e correlacionar os achados com a gravidade da síndrome da apneia obstrutiva do sono. Método Foram avaliados 21 indivíduos com queixas de ronco e/ou pausas respiratórias durante o sono, gênero masculino, entre 18 e 60 anos, brancos. Após avaliação clínica, exame físico otorrinolaringológico e nasofaringolaringoscopia flexível, todos foram submetidos à polissonografia tipo III. Os participantes foram divididos em dois grupos de acordo com a gravidade dos sintomas: grupo 1, ronco primário e/ou síndrome da apneia obstrutiva do sono leve (n = 9) e grupo 2, síndrome da apneia obstrutiva do sono moderada/grave (n = 12). Dimensões internas nasais foram aferidas por rinometria acústica, foram consideradas para análise as áreas de secção transversa mínima e os volumes de três diferentes segmentos nasais. Resultados O índice de eventos respiratórios correspondeu a 8,1 ± 4,0 no grupo 1 e 47,5 ± 19,1 no grupo 2. No grupo 1, os valores de área de secção transversa, em cm2, corresponderam a: área de secção transversa 1 = 1,1 ± 0,4; área de secção transversa 2 = 2,1 ± 0,9; área de secção transversa 3 = 3,5 ± 1,8. No grupo 2: área de secção transversa 1 = 1,2 ± 0,3, área de secção transversa 2 = 2,0 ± 0,5; áre de secção transversa 3 = 2,8 ± 0,7. No grupo 1 os valores do volume, em cm3, corresponderam a: volume 1 = 3,5 ± 1,0; volume 2 = 9,3 ± 5,0; volume 3 = 40,2 ± 21,5 e no grupo 2 a: volume 1 = 3,6 ± 0,5; V2 = 7,6 ± 1,5; volume 3 = 31,5 ± 6,7. Os valores de área de secção transversa e volume não diferiram entre os grupos. Conclusão Não foram demonstradas diferenças significantes quanto às áreas seccionais transversas e os volumes nasais entre indivíduos com ronco primário e síndrome da apneia obstrutiva do sono leve e síndrome da apneia obstrutiva do sono moderada-grave. Contrariamente à hipótese levantada, os resultados sugerem não existir relação entre as dimensões internas nasais e o nível de gravidade da síndrome da apneia obstrutiva do sono.

Rinoplastia de preservación dorsal, una nueva filosofía: Experiencia en el Hospital Naval Almirante Nef / Dorsal preservation rhynoplasty, a new philosophy: Experience in the Almirante Nef Naval Hospital

Resumen Introducción: La rinoplastia de preservación dorsal es una técnica innovadora en rinoplastias de reducción primaria, logrando una adecuada ventilación nasal y resultados estéticos naturales. Objetivo: Describir los resultados estéticos y funcionales en pacientes sometidos a rinoplastias de preservación dorsal. Material y Método: Se realiza un estudio de intervención no aleatorio "antes-después", donde se evaluaron las variables estética y funcional previo a la cirugía y luego a los seis meses. La variable estética se evaluó mediante el cuestionario de Utrecht (CU), escala visual análoga de apariencia nasal (EVA) y set de fotos clínicas. La variable funcional mediante el cuestionario de NOSE (Nasal Obstruction Symptoms Evaluation). Resultados: Un total de 15 pacientes fueron sometidos a rinoplastia de preservación dorsal. No hubo complicaciones tanto intra como posoperatorias. Ningún paciente intervenido presentó irregularidades dorsales, asimetrías, ni deformidades en "V" invertidas. Se observó una mejoría estadísticamente significativa (p < 0,01) en los resultados del CU, EVA y NOSE. Conclusión: La rinoplastia de preservación dorsal ofrece como resultado una nariz funcional, con líneas dorsales posoperatorias naturales. Esta técnica no presenta estigmas quirúrgicos, por lo que no es necesario la utilización de injertos para reparación del dorso nasal. Es rápida y fácil de realizar por cualquier cirujano especialista en rinoplastias.

Abstract Introduction: Dorsal preservation rhinoplasty is an innovative technique in primary reduction rhinoplasty, achieving adequate nasal ventilation and natural aesthetic results. Aim: To describe the aesthetic and functional results in patients undergoing dorsal preservation rhinoplasties. Material and Method: A non-randomized "before-after" intervention study was carried out, where the aesthetic and functional variables were evaluated before surgery and then at six months. The aesthetic variable was evaluated using the Utrecht questionnaire (CU), the visual analog scale of nasal appearance (VAS), and a set of clinical photos. The functional variable using the Nasal Obstruction Symptoms Evaluation (NOSE) questionnaire. Results: A total of 15 patients underwent dorsal preservation rhinoplasty. There were no intraoperative and postoperative complications. No patient who underwent surgery presented dorsal irregularities, asymmetries, or inverted "V" deformities. A statistically significant improvement (p < 0.01) was observed in the UC, VAS, and NOSE results. Conclusion: Dorsal preservation rhinoplasty results in a functional nose, with natural postoperative dorsal lines. This technique does not present surgical stigmata, so it is not necessary to use grafts to repair the nasal dorsum. It is quick and easy to perform by any rhinoplasty surgeon.

Enfermedad de Rosai-Dorfman nasosinusal: actualización a propósito de un caso de obstrucción nasal progresiva / Nasosinusal Rosai-Dorfman disease: update on a case of progressive nasal obstruction

Resumen La histiocitosis sinusal con linfadenopatías masivas, conocida como enfermedad de Rosai-Dorfman (ERD), es una patología poco frecuente cuya presentación clásica consiste en el desarrollo de grandes adenopatías cervicales bilaterales indoloras. La manifestación extranodal puede involucrar compromiso cutáneo, del sistema nervioso central, hematológico, óseo, de la vía aérea, entre otros. Su diagnóstico es un desafío y requiere una evaluación completa del paciente incluyendo historia clínica, examen físico, exámenes de laboratorio, imágenes y estudio histopatológico que confirme el diagnóstico. El tratamiento debe ser individualizado para cada paciente. Las alternativas incluyen la observación, corticoides sistémicos, radioterapia, quimioterapia, inmunomoduladores y cirugía. Se presenta el caso de una paciente de 65 años con antecedente de enfermedad de Rosai-Dorfman localizada en glándulas lagrimales y linfoma no Hodgkin, que comienza con obstrucción nasal bilateral progresiva refractaria a tratamiento médico, por lo que se decide realizar cirugía, cuyo estudio histopatológico confirmó enfermedad de Rosai-Dorfman.

Abstract Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare pathology, with a classic clinical presentation of painless bilateral massive cervical lymphadenopathy. The extranodal manifestations may involve skin, central nervous system, hematological, bones, and airway compromise, among others. Its diagnosis is challenging and requires a complete evaluation of the patient including medical history, physical examination, laboratory testing, imaging and histopathological study to confirm the diagnosis. Treatment should be individualized for each patient, including follow-up, systemic corticosteroids, radiotherapy, chemotherapy, immunomodulators and surgery. We present the case of a 65-year-old patient with a history of RDD located in the lacrimal glands and lymphoma, which begins with progressive bilateral obstruction refractory to medical treatment, for which it is decided to perform surgery, whose histopathological study confirmed RDD.
