RESUMEN
Objectives To evaluate the evolution of obstructive sleep apnea (OSA), comparing data from preoperative, immediate postoperative and late postoperative, in patients undergoing pharyngeal surgery associated with nasal surgery, and to compare the findings of arterial tonometry and type 1 polysomnography in the late postoperative period. Methods Seventeen adults with moderate or severe OSA were included in the study. They underwent clinical evaluation, surgical intervention, and sleep study preoperatively, on the 1 st night after surgery, and after a minimum period of 3 months. The data for the three moments were compared. Results The mean age was 38.1 ± 12.5 years old (22 to 59 years old), and 82.3% were male. Body mass index (BMI) ranged from 25.6 to 45.1 kg/m2 (mean = 33.1 ± 5.8 kg/m 2 ). Fifteen patients (88.2%) were diagnosed with severe OSA. There was a progressive improvement, with a decrease in the indexes (AHI and RDI) and in the percentage of time with peripheral oxyhemoglobin saturation below 90% (tSpO < 90%), and an increase in nadir of SpO2. In the comparison between the 2 methods used in the late postoperative period - arterial tonometry and polysomnography - there was no difference in the indexes and in the tSpO < 90%. Discussion There was a progressive and favorable impact of pharyngeal surgery on the improvement of polysomnographic and clinical respiratory parameters; however, many patients maintained residual OSA, suggesting the need for a new sleep study in the postoperative period. The arterial tonometry showed similar findings to polysomnography, which can be considered as an option in postoperative follow-up of patients.
RESUMEN
ABSTRACT INTRODUCTION: The mandibular advancement device (MAD) is a option to treat patients with Obstructive Sleep Apnea Syndrome (OSAS). OBJECTIVE: To assess the influence of upper airway abnormalities on the success of and adherence to MAD in patients with OSAS. METHODS: Prospective study with 30 patients with mild to moderate OSAS and indications for MAD. The protocol included questionnaires addressing sleep and nasal complaints, polysomnography, and upper airway assessment. The analyzed parameters of patients who showed therapeutic success and failure and those who exhibited good and poor treatment adherence were compared. RESULTS: 28 patients completed the protocol; 64.3% responded successfully to treatment with MAD, and 60.7% exhibited good adherence to treatment. Factors associated with greater success rates were younger age (p = 0.02), smaller cervical circumference (p = 0.05), and lower AHI at baseline (p = 0.05). There was a predominance of patients without nasal abnormalities among patients treated successfully compared to those with treatment failure (p = 0.04), which was not observed in relation to adherence. Neither pharyngeal nor facial skeletal abnormalities were significantly associated with either therapeutic success or adherence. CONCLUSION: MAD treatment success was significantly lower among patients with nasal abnormalities; however, treatment adherence was not influenced by the presence of upper airway or facial skeletal abnormalities.
RESUMO INTRODUÇÃO: O Aparelho Intraoral (AIO) é uma opção para tratamento da Síndrome da Apneia Obstrutiva do Sono (SAOS). OBJETIVOS: Avaliar a influência das alterações da VAS e esqueléticas faciais através de uma avaliação clinica sistematizada no sucesso e adesão ao (AIO) em pacientes com (SAOS). MÉTODO: Estudo prospectivo em que foram avaliados 30 pacientes com SAOS leve a moderada e indicação de AIO. Protocolo incluiu questionários de sono e queixas nasais; polissonografia e avaliação da VAS por rinoscopia anterior e oroscopia. Os parâmetros analisados foram comparados entre pacientes com sucesso e insucesso, e com boa e má adesão à terapia. RESULTADOS: Completaram o protocolo 28 pacientes. O sucesso ao tratamento foi de 64,3% e a adesão 60,7%. Os fatores associados ao sucesso foram menor idade, menor circunferência cervical e menor IAH basal. Quanto à presença de alterações nasais, houve predomínio de pacientes sem alteração nasal entre os pacientes com sucesso comparados àqueles com insucesso (p = 0,04); o que não foi observado em relação à adesão. Quanto às alterações faríngeas e alterações esqueléticas faciais, não houve significância. CONCLUSÃO: O sucesso do tratamento com AIO foi significativamente menor nos pacientes com alterações nasais, porém a adesão não foi influenciada pela presença de alterações de VAS ou esqueléticas faciais.

Sabe-se que o sono não é simplesmente ausência de vigília nem um processo passivo. É um estado ativo e cíclico, vinculado a controles hormonais, metabólicos, bioquímicos e de temperatura, imprescindíveis à vida. Insônia é a dificuldade ou incapacidade para iniciar ou manter o sono, também pode expressar-se por uma duração demasiadamente curta do sono ou por não ser reparador. A deficiência de sono presente pode originar alterações psíquicas, diminuição do aprendizado e da capacidade laboral; maiores riscos de acidentes de trabalho e trânsito; aumento da taxa de mortalidade por doenças isquêmicas e câncer. A apresentação na população idosa deste evento se caracteriza por ser acompanhada nos dias que a seguem por sonolência excessiva diurna, irritabilidade, cefaleias, confusão mental, alterações cognitivo-comportamentais, dores neuromusculares, sonolência patológica, crises convulsivas e coma.
