Myofunctional assessment for obstructive sleep apnea and the association with patterns of upper airway collapse: a preliminary study.

Objectives: To organize an assessment instrument with questionnaires and myofunctional orofacial/oropharyngeal assessment for OSA patients and correlate it with the upper airway obstructive site detected during drug-induced sleep endoscopy (DISE). Material and Methods: 29 OSA patients aged 22-65 years with an indication to undergo DISE to evaluate an alternative treatment to PAP and signed the consent form. Patients over 65 years old with maxillofacial deficiency and BMI>30 were excluded. The subjects answered the Pittsburgh, Berlin (snore), and Epworth questionnaires. The myofunctional orofacial/oropharyngeal assessment comprised soft palate, palatine pillars, and uvula (structure and mobility), tonsils (size), mandible (bony bases), hard palate (depth and width), tongue (posture, volume, width, and height), floor of mouth (mylohyoid), tongue suction and sustaining (mobility), "lowering of the back of the tongue" (stimulus), which were scored by three speech-language pathologists with expertise. DISE was scored according to VOTE classification. The statistical analysis (t-test) compared groups without and with obstruction in VOTE with questionnaires and myofunctional orofacial/oropharyngeal assessment. Results: The following were significantly different: snoring frequency (p=0.03) with VOTE/velopharynx; intensity (p=0.02) and frequency of snoring (p=0.03) with VOTE/lateral wall of oropharynx; suction the tongue and sustain (p=0.02) with VOTE/velopharynx; hard palate depth (p=0.02) and width (p=0.05) with obstruction VOTE/epiglottis; tonsils volume (p=0.05) with VOTE/epiglottis; tongue posture (p=0.00) with obstruction VOTE/epiglottis; floor of the mouth (p=0.02) with VOTE/epiglottis. Conclusion: Higher snoring frequency and intensity was observed in patients with obstruction at the velopharynx and oropharyngeal lateral wall. Obstruction at the velopharynx was associated with poor tongue ability to suck the tongue against the hard palate. Obstruction at the epiglottis had structural and functional associations, including the oropharyngeal lateral wall, affected by the palatine tonsils size, depth and width of the hard palate, tongue position, and flaccidity of the floor of mouth. Considering that this is a preliminary study, the data should be carefully verified and not generalized.

Obstructive Sleep Apnea: characterization of the obstructive site and type of collapse. / Apneia Obstrutiva do Sono: caracterização do sítio obstrutivo e tipo de colapso.

Obstructive Sleep Apnea is characterized by recurrent episodes of partial or complete collapse of the pharynx, followed by decreased oxyhemoglobin saturation and frequent arousals. It is regarded as a public health issue with important night and day symptoms that impact life quality. Its effects are associated with the areas of competence of Speech and Language Pathologists. To establish efficient diagnosis and treatment methods, professionals must know the pathogenesis of upper airway obstruction during sleep. This study seeks to enlarge the understanding of obstructive sleep apnea pathophysiology, eligibility of individualized therapeutic procedures and guidance for orofacial myofunctional therapy by describing and illustrating the locations and types of upper airway collapse during sleep. We analyzed original records of Drug Induced Sleep Endoscopy exams of a series of cases with polysomnographic diagnosis of obstructive sleep apnea following the proper ethical processes. The images of the exam recordings were analyzed by five professionals with expertise in the sleep area. Obstructive sites and types of collapse were presented according to the current classification. The videos were divided into screenshots, originating figures from each anatomical site: without collapse and collapsed. The results are visualized in the images of the cases showing a predominance of velopharyngeal collapse: anteroposterior, lateral, or concentric; oropharyngeal lateral collapse; tongue anteroposterior collapse and anteroposterior collapse of the epiglottis. Understanding the obstruction sites and types of collapse illustrated in this study may help to predict therapeutic responses and learn the limitations or direct individual proposals patient.

A Apneia Obstrutiva do Sono caracteriza-se por episódios recorrentes de colapso parcial ou completo da faringe, seguidos de diminuição da saturação de oxihemoglobina e despertares frequentes. É considerada problema de saúde pública com importantes sintomas noturnos e diurnos, impactando qualidade de vida. Seus efeitos associam-se as áreas de competência da Fonoaudiologia. Para estabelecer diagnóstico e métodos de tratamento eficientes, profissionais devem conhecer a patogênese da obstrução da via aérea superior durante o sono. Visando contribuir para a compreensão da fisiopatologia da apneia obstrutiva do sono, elegibilidade de procedimentos terapêuticos individualizados e direcionamento para terapêutica miofuncional orofacial, o presente estudo tem como objetivo descrever e ilustrar os locais e tipos de colapso da via aérea superior durante o sono. Após processos éticos, foram analisados registros originais das sonoendoscopias de uma série de casos com diagnóstico polissonográfico de apneia obstrutiva do sono. As imagens das gravações dos exames foram analisadas por cinco profissionais com expertise na área do sono. Os locais obstrutivos e tipos de colapso foram apresentados conforme classificação vigente. Os vídeos foram divididos em capturas de tela, originando figuras de cada sítio anatômico: sem colapso e com colapso. Os resultados foram apresentados por imagens dos casos, que ilustram cada colapso, predominando colapso velofaríngeo: anteroposterior, lateral ou concêntrico; seguido por colapso orofaríngeo lateral; colapso anteroposterior na hipofaringe e colapso anteroposterior da epiglote. O entendimento dos locais de obstrução e tipos de colapso ilustrados nesse estudo pode ser um preditor de respostas terapêuticas, auxiliando a compreensão das limitações ou direcionando propostas para cada paciente.

A comparison of the Fujita classification of awake and drug-induced sleep endoscopy patients.

UNLABELLED: Only a few studies have compared the outcomes of patients kept awake during endoscopic examination and subjects submitted to drug-induced sleep endoscopy. OBJECTIVE: This study aimed to compare the endoscopic findings of patients submitted to outpatient endoscopy and endoscopic examination with sedation by propofol based on the Fujita Classification. METHOD: This cross-sectional cohort study enrolled 34 patients. The subjects underwent ENT examination, nasal endoscopy with Müller's maneuver, and drug-induced sleep endoscopy with propofol. The Fujita Classification was used to compare the two modes of endoscopic examination. The examinations were correlated to patient clinical data such as BMI, age, and OSAS severity. RESULTS: There was no agreement between the two modes of endoscopic examination, whether for the group in general or for the analyzed subgroups. CONCLUSION: There was no agreement between the endoscopic findings of endoscopic examinations done with the patient awake or in drug-induced sleep.

Comparativo da classificação de Fujita no paciente acordado e sob sonoendoscopia / A comparison of the Fujita classification of awake and drug-induced sleep endoscopy patients

São poucos os estudos que comparam resultados endoscópicos no paciente acordado com o mesmo paciente sob sono induzido por drogas. OBJETIVOS: O objetivo do presente estudo é comparar os acha dos endoscópicos num mesmo paciente, em dois momentos diferentes: ambulatorial e sob sedação com propofol, por meio da classificação de Fujita. Desenho do estudo: estudo de coorte transversal. MÉTODO: Trinta e quatro pacientes foram submetido ao exame otorrinolaringológico ambulatorial, incluindo nasoendoscopia com manobra de Müller com o paciente acordado e à sonoendoscopia com propofol. A classificação de Fujita foi adotada para comparar os dois exames endoscópicos. Correlacionamos a concordância entre os exames com dados clínicos dos pacientes, como Índice de Massa Corporal, idade e gravidade da síndrome da apneia obstrutiva do sono. RESULTADOS: Não houve concordância nenhuma entre os dois exames endoscópicos, seja para o grupo no geral, seja para cada um dos subgrupos analisados. CONCLUSÃO: Não existe concordância entre os achados endoscópicos com o paciente acordado e os mesmos com o paciente com sono induzido.

Surgical treatment of nasal packing refractory epistaxis.

UNLABELLED: Epistaxis is the main otorhinolaryngology emergency and, in severe cases, it can lead to hemodynamic instability and be life threatening. AIM: To evaluate factors involved in epistaxis resistant to nasal packing that needed surgical treatment, as well as post-surgical results. MATERIAL AND METHODS: Retrospective study from January 2002 to August 2007. 40 consecutive patients that underwent surgical treatment for refractory epistaxis were analyzed. Predisposing factors, procedures performed, need of blood transfusion, and recurrence were evaluated. RESULTS: Otorhinolaryngology post operative complications (37.5%), high blood pressure (30%), and coagulopathy (15%) were the main factors related to epistaxis. 50% of the patients (n=20) presented with hemodynamic instability and 90% of them (n=18) needed blood transfusion. Eletrocauterization of the bleeding site was enough in 35% of these patients (n=14), while in 65% (n=26) was necessary cauterization and/or arterial ligation. Five patients (12.5%) had bleeding recurrence, which needed re-operation. CONCLUSION: Earlier indications of surgical treatment to control severe and refractory epistaxis to conventional treatment, especially in a population with high risk such as post operative bleeding and coagulopathies, may decrease the need of blood transfusion.

A epistaxe é a principal emergência otorrinolaringológica e, em casos graves, pode comprometer a estabilidade hemodinâmica colocando em risco a vida do paciente. OBJETIVO: Avaliar fatores envolvidos na epistaxe e a evolução de pacientes que necessitaram de tratamento cirúrgico em casos refratários a tratamento com tamponamento nasal. MATERIAL E MÉTODOS: Estudo retrospectivo transversal, sendo avaliados 40 pacientes consecutivos com epistaxe refratária a tratamento clínico convencional que necessitaram de tratamento cirúrgico, entre o período de janeiro de 2002 a agosto de 2007. Foram avaliados fatores relacionados à epistaxe, bem como os resultados pós-operatórios. RESULTADOS: Os principais fatores relacionados foram complicações pós-operatórias de cirurgia otorrinolaringológica (37,5 por cento), hipertensão arterial sistêmica (30 por cento) e coagulopatia (15 por cento). Como complicação da epistaxe, 50 por cento (n=20) apresentaram instabilidade hemodinâmica e 90 por cento desses (n=18) necessitaram de transfusão sanguínea. Em 35 por cento dos pacientes (n=14) foi necessária apenas a cauterização elétrica do sítio sangrante, enquanto que 65 por cento (n=26) necessitaram de cauterização e/ou ligadura vascular. Em cinco casos (12,5 por cento) houve recorrência da epistaxe necessitando de reintervenção cirúrgica. CONCLUSÕES: Em pacientes sob risco de epistaxe grave, como sangramento pós-operatório e coagulopatia, indicações cirúrgicas mais precoces poderiam diminuir a necessidade de transfusões sanguíneas.
