Airway Pressure,Plasma Radiofrequency Ablation and Modified Uvuopalatopharyngoplasty Treat Severe Obstructive Sleep Apnea Syndrome

Objective To investigate the therapy methods,improve the clinical efficacy and reduce the complications on severe obstructive sleep apnea syndrome(OSAS).Methods 15 patients with polysomnographically proven serious obstructive sleep apnea hypopnea syndrome were given continue positive airway pressure for 1 week before plasma radiofrequency ablation to uvula,tongue base,soft palate and inferior turbinates and modified uvuopalatopharyngoplast enlarged oropharyngeal air duct.The polysomnography examinations were carried out before and 12 weeks after operation respectively.The snoring scale and Epworth sleepiness score(ESS) were also compared.Results Three to six months follow-up showed that Comparison of polysomnography parameters before and 12 weeks after operation showed that Ⅰ+Ⅱ phase sleep time shortened significantly,Ⅲ+Ⅳ phase sleep time prolonged,sleep efficiecy and the lowest pulse oxygen saturation improved signifiantly.In addition,there were significant differences in the decrease of apnea hypopnea index after operation (P0.01).12 weeks after treatment,the lenth of soft palate and uvula shortened,snoring scale and ESS decreased significantly (P0.01).Conclusion Continue positive airway pressure,plasma radiofrequency ablation and modified uvuopalatopharyngoplasty is effective to severe OSAHS at least in a short term.This treatment is convenient,simple safe and minimally invasive procedure without obvious adverse reactions.There are better prospects and it is worth popularizing and applying.
