          Abstract

          ASAHOS é uma doença importante no cenário médico atual pela sua correlação com doenças cardiovasculares crônicas e suas consequências socioeconômicas. OBJETIVOS: Determinar a correlação entre a classificação de Friedman com a gravidade da doença pelo Índice de Apneia e Hipopneia em pacientes com SAHOS, para a avaliação e indicação cirúrgica. MATERIAIS E MÉTODOS: Estudo transversal. Foram avaliados e classificados 143 pacientes, na escala de Epworth, Friedman e quanto à gravidade da SAHOS pelo IAH. RESULTADOS: 112 pacientes se submeteram ao estudo de polissonografia no laboratório de sono. Uma crostabulação foi feita entre a Classificação de Friedman e o IAH. As variáveis se relacionam com p<0,05. Encontramos uma relação em que os pacientes com SAHOS leve tendem a ter uma menor classificação de Friedman (melhores resultados cirúrgicos). Da mesma forma os pacientes classificados como SAHOS moderada a grave possuem maior prevalência da classificação de Friedman III e IV (menor sucesso com uvulopalatofaringoplastia). p<0.05. CONCLUSÃO: Concluímos que a classificação de Friedman se correlaciona com a gravidade da SAHOS. Quanto maior a classificação de Friedman, maior tende a ser a gravidade da apneia nesse estudo.

          OSAHS is an important disease in current medical settings because of its association with chronic cardiovascular diseases and socioeconomic impacts. AIMS: to establish the correlation between the Friedman Classification and the OSAHS severity through the Apnea-Hypopnea Index) in patients with OSAHS for assessment and surgery purposes. MATERIALS AND METHODS: Cross-sectional study. We evaluated and classified 143 patients, using the Epworth's and Friedman's scale and OSAHS severity according to the AHI. RESULTS: 112 patients were submitted to polysomnography. We compared the Friedman Score and the IAH. The variables were associated with p<0.05. We found that patients with light OSAHS, tended to have a lower Friedman classification (better surgical result). By the same token, patients with moderate to severe OSAHS had a greater prevalence of Friedman's score of III and IV; p< 0.05 (lower success rates from uvulopalatopharyngoplasty). CONCLUSION: We conclude that the Friedman's classification correlates with OSAHS severity - the higher the Friedman's score, the more severe is the OSAHS.

            Four-year follow-up after uvulopalatopharyngoplasty in 50 unselected patients with obstructive sleep apnea syndrome.

            Fifty unselected consecutive patients with obstructive sleep apnea syndrome (OSAS) diagnosed by nocturnal recordings of respiration movements by a static charge sensitive bed (SCSB) and oximetry, alone or combined with polysomnography, were studied. Renewed SCSB-oximetry recordings evaluated treatment. Six months after surgery, 30 of 50 were classified as responders. Twenty-one months after surgery, 19 of 49 were responders. Patients who relapsed showed a significant increase in mean body mass index (BMI). Four years after surgery, 24 of 48 patients were responders. Preoperative BMI was significantly lower in the responder group. Subsequent treatment was required in 15 nonresponders. There was no correlation between patients' subjective improvement and objective results. The study resulted in the following conclusions: 1. The responder rate to UPPP in unselected patients is low. 2. Obesity and high indices of nocturnal respiratory disturbance are negative predictors. 3. The patients' subjective recovery alone must not be used for postoperative evaluation. 4. With regular follow-up and the use of the treatment alternatives available today, the majority of OSAS patients can receive effective treatment.
