Desviación septal nasal en relación con las deformidades nasales externas: un estudio observacional / Nasal septal deviation in relation to external nasal deformities: an observational study

La nariz es estructuralmente compleja, y esta complejidad da como resultado variaciones de forma nasal. El estudio tuvo como objetivo determinar las desviaciones septales nasales que ocurren en relación con las deformidades nasales externas. Se realizó un estudio transversal en el departamento de oído, nariz y garganta, en nuestro hospital. Todos los individuos que tienen desviación septal con deformidad nasal externa de noviembre de 2017 a noviembre de 2018. Esos pacientes serán evaluados mediante un examen clínico integral de la oreja, la nariz y la garganta. Los síntomas del paciente se clasifican con el cuestionario de prueba china nasal -22. Las deformidades septales se clasificaron utilizando la clasificación Mladina modificada. Las deformidades nasales externas se clasificaron empleando la clasificación de Yong Jo Jang. Aproximadamente, el 43% eran hombres y el 57% eran mujeres. Alrededor del 90% de los pacientes de 21 años a 50 años. Alrededor del 58% de los pacientes eran sintomáticos, mientras que el resto del 42% no tenía síntomas. Al correlacionar los síntomas con el tipo de desviación, se encontró significativamente asociación (P = 0.05). La mayoría de las personas se encuentran en el grupo de mediana edad. Tipo II y IV son los tipos más comunes de NSD, mientras que el tipo I es un final común. El encuentro notable de nuestro estudio es que los pacientes no tenían deformidad

The nose is structurally complex, and this complexity results in nasal shape variations. The study aimed to determine the nasal septal deviations occurrence in relation to external nasal deformities. A crosssectional study was conducted in Department of Ear, Nose and Throat, in our hospital. All the individuals having septal deviation with external nasal deformity from November 2017 to November 2018. Those patients be evaluated by comprehensive clinical examination of ear, nose and throat. Patient's symptoms are rated with Sino-Nasal Test -22 questionnaire. Septal deformities were classified using Mladina classification modified. External nasal deformities were classified employing Yong Jo Jang's classification. Approximately, 43% were males and 57% were females. About 90% of patients aged from 21 years to 50 years. About 58% of patients were symptomatic while the rest 42% were without symptoms.

Diagnostic and therapeutic endonasal rhinologic procedures generating aerosol during COVID-19 pandemic: a systematized review / Procedimentos endonasais de rinologia diagnósticos e terapêuticos geradores de aerossóis durante a pandemia de Covid-19: uma revisão sistematizada,

Abstract Introduction Most rhinologic procedures, particularly endoscopic sinonasal procedures, are liable to produce aerosols. The severe acute respiratory syndrome coronavirus 2 (SARS-Co V-2) transmits via respiratory droplets, but the degree of its spread through airborne routes by aerosol is unclear. Objective The aim of this article is to counsel rhinologists on how to modify their conventional practice during the COVID-19 pandemic by prioritising the need of procedures, identifying aerosol- generating procedures and using precise personal protection equipment for various endonasal procedures. Methods We did a review of articles indexed for MEDLINE on PubMed, ENT Cochrane, DOAJ and Web of Science databases using the keywords nasal endoscopy, SARS-CoV-2, COVID-19, aerosol generating medical procedures and rhinology to formulate guidelines for the safety of healthcare workers. Results The review included evidence from 28 articles from the otorhinolaryngology, surgery, infectious disease, head and neck surgery and cancer biology literature. We have provided recommendations and relevant information for rhinologists during the COVID-19 pandemic, based on the available studies and data, to warrant high-quality patient care and requisite levels of infection prevention during rhinology procedures. Conclusion In rhinology, marked care is advised during nasal packing, electrocauterisation and use of high-speed rotating devices in potentially infected tissue as they are considerable aerosol- producing procedures. The choice of personal protective equipment is based on the risk of exposure and possible modes of aerosol generation.

Conclusões Em rinologia, recomenda-se cuidado acentuado durante o tamponamento nasal, eletrocauterização e uso de dispositivos rotativos de alta velocidade em tecidos potencialmente infectados, pois esses procedimentos são consideráveis produtores de aerossóis. A escolha do equipamento de proteção individual é baseada no risco de exposição e nos possíveis modos de geração de aerossol.

Mucocele de cavidades paranasales / Sinus mucocele

Los mucoceles son quistes expansivos e indolentes de las cavidades paranasales. A pesar de ser lesiones benignas, tienen potencial destructivo local por su expansión crónica y cambios óseos. Su ubicación más frecuente es frontoetmoidal. Se postula que su origen es por alteración de la vía de drenaje de los senos. La clínica es dependiente de su ubicación: los mucoceles frontoetmoidales presentan aumento de volumen, cefalea o proptosis. Las imágenes juegan un rol importante en el diagnóstico, siendo la tomografía computarizada y la resonancia magnética los exámenes que detectan patrones sugerentes de mucoceles. El tratamiento es quirúrgico, donde el abordaje endoscópico ha desplazado al abierto por ser mínimamente invasivo, presentar menos comorbilidades y tener menor tasa de recurrencia.

Mucoceles are expansive and indolent cyst of the paranasal cavities. Despite being benign lesions, they have local destructive potential because of its chronic expansion and bony changes. Its most common location is frontoethmoidal. Alterations in the drainage pathway of sinus is thought to be the origin of mucoceles. The clinical features depend on the location. Frontoethmoidal often presents frontal swelling, headache or proptosis. Imaging plays an important part of diagnosis. Tomography and magnetic resonance have patterns that can suggest the presence of a mucocele. Paranasal sinus mucoceles are primarily treated surgically. The endoscopic surgical management has replaced the open resection because of its minimally invasive treatment, less morbidity and low recurrence rates.

Avaliação da radiografia cefalométrica lateral como meio de diagnóstico da hipertrofia de adenoide / Evaluation of lateral cephalometric radiography as a mean of diagnosing adenoids hypertrophy

INTRODUÇÃO: a hipertrofia de adenoide é uma das principais causas da respiração bucal. Entre os métodos utilizados para o diagnóstico dessa condição, os mais precisos são a endoscopia nasal e a ressonância magnética. No entanto, o método mais utilizado, em Odontologia, é a radiografia cefalométrica lateral. OBJETIVO: determinar a eficácia dessa radiografia no diagnóstico da hipertrofia de adenoide, pela sua comparação com a endoscopia nasal. MÉTODOS: foram avaliados 30 indivíduos (7 a 12 anos). Todos fizeram exame de endoscopia nasal e radiografia cefalométrica lateral. Nas endoscopias, foi registrada a porcentagem de obstrução da nasofaringe e, nas radiografias, a menor dimensão anteroposterior livre da nasofaringe. RESULTADOS: os exames se mostraram fortemente correlacionados (r = - 0,793, p-valor < 0,01). Considerou-se portadores de hipertrofia severa de adenoide os pacientes que apresentaram, na endoscopia, obstrução da nasofaringe igual ou superior a 75 por cento e, nas radiografias, o menor diâmetro anteroposterior da nasofaringe igual ou inferior a 5mm; o exame radiográfico teve uma sensibilidade de 75 por cento, especificidade de 86,3 por cento, valor preditivo positivo de 66,7 por cento, valor preditivo negativo de 90,4 por cento e exatidão de 83,3 por cento. CONCLUSÃO: a radiografia cefalométrica lateral se mostrou um exame eficiente para o diagnóstico da hipertrofia de adenoide.

INTRODUCTION: One of the most usual causes of mouth breathing is adenoids hypertrophy with reduction of the nasopharyngeal space. The most precise diagnostic methods are magnetic resonance and nasal endoscopy, because they make possible a three dimension image of the nasopharynx. However, in Dentistry, cephalometric radiography is the method used in the majority of cases. That is why it is so important the evaluation of the efficacy of this diagnostic method. AIM: The aim of this paper is to determine the efficacy of the lateral cephalometric radiography in diagnosing adenoids hypertrophy, comparing this method to the nasal endoscopy. METHODS: Thirty patients (7 to 12 years), with no history of otolaryngological surgery, were evaluated. All of them were submitted to a nasal endoscopy and a lateral cephalometric radiography. In the endoscopic exams it was registered the percentage of nasopharyngeal obstruction and in the radiographic exams it was registered the minor nasopharyngeal dimension. RESULTS: The results of the exams showed a strong correlation with each other (r = - 0.793, p-value < 0.01). After that, reliability tests to the radiographic diagnose were performed, assuming that 75 percent (endoscopic exams) and 5mm (radiographic exams) were the limit values to the determination of the diagnose of severe adenoids hypertrophy. The radiographic exam showed a sensibility of 75 percent, specificity of 86.3 percent, positive predictive value of 66.7 percent, negative predictive value of 90.4 percent and an exactness of 83.3 percent. Therefore, lateral cephalometric radiography is an efficient method of adenoids hypertrophy diagnose. It was proved by the strong correlation of its results with the results of the nasal endoscopy, that is considered a method of excellence for diagnosing this condition.
