To determine which analysis is suitable to examine the dentofacial skeletal pattern characteristics of the obstructive sleep apnea syndrome (OSAS), we took lateral cephalograms of 44 Japanese OSAS patients and 34 Japanese non-OSAS controls. By Ricketts analysis, we found significant differences between OSAS patients and non-OSAS controls on facial axis, lower facial height and total facial height, which showed that Japanese OSAS patients have dolico facial patterns. However, by Downs-Northwestern analysis, we did not find any significant difference between OSAS patients and non-OSAS controls using the same cephalograms as the Ricketts analysis.

“…Em relação à hipertensão pulmonar, vários estudos apontam para o benefício do tratamento da SAOS pela diminuição da hipóxia e sua ação na vasorreatividade pulmonar e na melhora da disfunção endotelial 42,43 . Avaliação de 12 semanas de terapia efetiva com CPAP demonstrou redução de 4,9 + 3,9mmHg (IC 95% 3,04-6,67 mmHg) [15,1 + 11,2% (IC 95% 10,[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]3%)] nos níveis da pressão sistólica da artéria pulmonar, passando de 28,9 + 8,6 mmHg para 24 + 5,8 mmHg (p<0,0001). Assim, admite-se que o tratamento adequado em longo prazo com o CPAP poderia evitar o desenvolvimento de alterações estruturais pulmonares e do ventrículo direito, mudando o prognóstico desses pacientes 43 .…”

RESUMOIntrodução. A Síndrome da Apneia Obstrutiva do Sono (SAOS) é caracterizada por obstrução parcial ou completa da via aérea superior, de forma intermitente e recorrente durante o sono. As principais manifestações durante o sono incluem roncos, pausas respiratórias, fragmentação do sono, levando a prejuízos diurnos incapacitantes, como sonolência excessiva diurna, alterações cognitivas e cefaléia matinal. Além das manifestações respiratórias clássicas, resulta em alterações metabólicas e hemodinâmicas que predispõem ao desenvolvimento e agravamento de doenças cardiovasculares, tais como hipertensão arterial sistêmica, insuficiência cardíaca congestiva, doença arterial coronariana e arritmias. Objetivo. Abordar aspectos clínicos, fisiopatológicos e diagnósticos da SAOS, bem como seus efeitos deletérios no sistema cardiovascular. Método. Revisão da literatura acerca da SAOS e suas consequências cardiovasculares através de artigos selecionados no PubMed. Conclusão. A apneia obstrutiva do sono e as doenças cardiovasculares têm origem multifatorial e alta prevalência na população mundial. Considerando que as doenças cardiovasculares são a maior causa atual de morbidade e mortalidade no mundo, a determinação de fatores de risco possíveis de controle e tratamento, como a SAOS, torna-se fundamental para prevenção e tratamento das doenças cardiovasculares.Unitermos.

Obstructive Sleep Apnea Syndrome (OSAS) is characterized by partial or complete obstruction of the upper airway, intermittently and recurrently during sleep. The main manifestations during sleep include snoring, pauses in breathing, sleep fragmentation, resulting in excessive daytime sleepiness, cognitive dysfunction and morning headaches. Besides the classic respiratory symptoms, OSAS results in metabolic and hemodynamic alterations that predispose to the development and worsening of cardiovascular diseases such as hypertension, congestive heart failure, coronary artery disease and arrhythmias. Objective. Reporting clinical, pathophysiological and diagnostic aspects of OSAS and its deleterious effects on the cardiovascular system. Method. Review of literature about OSAS and its cardiovascular consequences through selected articles in PubMed. Conclusion. Obstructive sleep apnea and cardiovascular diseases have multifactorial origin and high prevalence in the global population. Because cardiovascular diseases are the main cause of the current morbidity and mortality worldwide, determining possible treatable risk factors, such as OSAS, it is fundamental to prevention and treatment of cardiovascular diseases.

Abstract:Purpose: Obstructive sleep apnea (OSA) is a common disease that is estimated to affect 2% of middle-aged women and 4% of middle-aged men. Reported risk factors include obesity, increased neck circumference, male sex and anatomical abnormalities of the face. Although edentulism is reported to change the anatomy and also impair the function of the upper airway, it has not been typically recognized as a risk factor for sleep-related breathing disorders. Methods:The subject of this report is a 55 years old man with a body mass index (BMI) of 33 kg/m 2 . Cephalometric assessments of head radiographs taken in the lateral plane with and without dentures were performed; mandible planehyoid (MP-H) distance and the posterior airway space (PAS) were measured. Oxygen saturation (SaO 2 ) and apnea/hypopnea index (AHI) were evaluated.Results: A comparison of the polysomnographies taken with and without wearing the dentures during the night showed that AHI was reduced (from 20.0/h to 5.7/h) and mean SaO 2 increased (from 94.0% to 96.0%). Cephalometric analysis showed that the removal of dentures led to a striking increase in the anteroposterior oropharyngeal wall distance from 5 mm to 10 mm, while the mandible plane-hyoid distance does not change. Conclusions:These findings were consistent with the hypothesis that edentulism not always worse OSA by an oropharyngeal collapse. Given the common occurrence of both conditions among the elderly, such as the reduction of obstructive sleep apneas with or without dentures, the observed relationship requires further investigations on the mechanisms through which the loss of teeth could help upper airway collapse during the night. In the present paper a case of reduction of OSA without dentures during sleep is shown.
