The Application And Clinical Effect Of Temperature-controlled Radiofrequency Ablation In The Adults With Obstructive Sleep Apnea Hypopnea Syndrome

Objective: To investigate the effect and clinical value evaluation oftemperature-controlled radiofrequency ablation in the adults withobstructive sleep apnea hypopnea syndrome (OSAHS).Methods: The medical records of52patients who underwenttemperature-controlled radiofrequency ablation between January2010andJanuary2012were assessed(20moderate cases,32severe cases).Weoperated on the patients in the different upper airway plane such asinferior turbinate, soft palate, uvula, tonsils, base of the tongue andthe tongue and so on. The patients were followed up for one year, whoreviewed polysomnography (PSG). We evaluate the efficacy of surgerythrough the sleep apnea-hypopnea index (AHI) and lowest oxygen saturation(LSaO2) before and after treatment.Results: Average AHI before and after surgery was46.8±23.5and24.1±19.7. The average LSaO2value was68.5±20.2and79.1±15.5. Thepostoperative AHI and LsaO2were significantly improved (P <0.05). In the52patients,7cases (13.5%) were cured,28cases were significant effect(53.8%),14cases were effective (26.9%) and3cases were invalid(5.8%).The total effective rate amount to94.2%.Conclusion: The temperature-controlled radiofrequency ablation in theadults with OSAHS is simple, safety, minimally invasive treatment and painsmall, fast recovery.Moreover it can be repeated treatment and was easyto accept for patients. Temperature-controlled radiofrequency ablationcan be carried out on in the different upper airway plane,which can significantly improve the quality of patients life.This surgery isworthy of widespread use.
