RESUMO

Uvulopalatofaringoplastia (UPFP) foi realizada em 12 pacientes com apnéia do sono tipo obstrutiva. Comparamos aqui dados clínicos e traçados polissonográficos pré-operatórios aos realizados de um a três meses após a cirurgia. Sonolência excessiva diurna foi reduzida parcialmente em 4 casos e totalmente em 8. Tempo total de sono, eficiência do sono, número de despertares e latência do sono mantiveram-se constantes. A latência REM foi acentuadamente maior após a cirurgia. A distribuição dos estágios de sono foi semelhante nas duas avaliações exceto pela ausência de estágio 4 verificada em menor número de casos no pós-operatório. Houve melhora da SaO2, encontrando-se valores abaixo de 80% em 10 pacientes no pré e em 4 no pós-operatório. Os índices de apnéia reduziram-se em todos os casos, mas em apenas 4 atingiram valores normais.

SUMMARY

Uvulopalatopharyngoplasty (UPPP) was performed in 12 patients with obstructive sleep apnea. Pre-surgical clinical and polysomnographic data were compared with those one to three months after surgery. Excessive daytime sleepiness was partially improved in 4 cases and completely abolished in 8. Total sleep time, sleep efficiency, number of arousals and sleep latency were similar in both evaluations. REM latency to stage 2 markedly increased on the follow-up. Stage distributions were similar in both nights except for stage 4 which was more frequently absent on the first recording. Sa02 levels below 80% were seen in 10 cases before UPPP and in 4 after it. Apnea index decreased in all cases but it reached normal levels only in 4.
