Factors Associated with Successful Treatment by Radiofrequency Treatment of the Soft Palate in Obstructive Sleep Apnea as the First-Line Treatment

Background. Radiofrequency ablation (RFA) is recommended as the second-line treatment for obstructive sleep apnea (OSA). This study aims to study the factors associated with successful treatment by RFA in OSA patients as the first-line treatment. Methods. All patients diagnosed as mild to moderate O...

description Background. Radiofrequency ablation (RFA) is recommended as the second-line treatment for obstructive sleep apnea (OSA). This study aims to study the factors associated with successful treatment by RFA in OSA patients as the first-line treatment. Methods. All patients diagnosed as mild to moderate OSA were enrolled prospectively and treated with RFA. Three points of soft palate were ablated: midline, left, and right paramedian sites. Baseline characteristics and clinical factors including snoring score (SS), Epworth Sleepiness Scale (ESS), and apnea-hypopnea index (AHI), with minimal oxygen saturation, were recorded at baseline and three months after treatment. Results. During the study period, there were 51 patients who met the study criteria and received RFA treatment. At three months, the SS, ESS, and AHI were significantly lower than baseline values, while the minimal oxygenation was significantly increased from the baseline values. There were 16 patients (31.37%) who had an AHI of < 5 times/h. Only baseline AHI was significantly associated with an AHI of < 5 times/h at three months after RFA treatment. The adjusted odds ratio was 0.804 (95% CI: 0.699, 0.924). Conclusion. Transoral RFA treatment may be effective in mild to moderate OSA as the first-line treatment. Baseline AHI is associated with preferable outcome by RFA treatment.
