[Efficacy of weight management combined with uvulopalatopharyngoplasty for obesityrelated obstructive sleep apnea-hypopnea syndrome].

OBJECTIVE To evaluate the clinical efficacy of weight management combined with pharyngoplasty for treatment of obesity-related obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS Sixty obese patients with OSAHS were randomly assigned into the combined treatment group and control group (n=30) and received treatment with uvulopalatopharyngoplasty (UPPP) combined with cognitive-behavioral-psychological intervention for family weight management and uvulopalatopharyngoplasty with conventional management. At 3 and 6 months of the treatment, the patients were examined for changes in body mass index (BMI), neck circumference, waist circumference, Epworth Sleepiness Scale (ESS) scores, apnea-hypopnea index (AHI), the lowest oxygen saturation (LSaO2) and the percentage of time with oxygen saturation below 90% (CT90). RESULTS After 6 months of treatment, the patients receiving the combined treatment showed significant reductions of BMI, neck circumference and waist circumference as compared with the measurements before treatment and with those in the control group (P 0.05). In the combined treatment group, the ESS score, CT90, AHI, and LSaO2 at 6 months were all superior to those in the control group (P 0.05) but a significantly higher good response (defined as an AHI < 20 h-1 and an AHI reduction by ≥50%) rate (60% vs 35.7%; χ2=8.71, P < 0.01) and a higher overall response (a AHI reduction ≥50%) rate (83.3% vs 53.6%; χ2=10.62, P < 0.01). CONCLUSIONS Weight management combined with uvulopalatopharyngoplasty can produce a good clinical efficacy for treatment of OSAHS with obesity, and the patients should have strengthened continuous family weight management while receiving surgical treatment.
