| Abstract: | OBJECTIVE: To compare the efficacy and safety of four radiofrequency generators (Ellman, Select Sutter, Coblator, Somnus) for the treatment of simple snoring. MATERIALS AND METHODS: Multicenter, randomized, prospective single-blind study on 120 selected patients with simple snoring (apnea/hypopnea index <10/h of sleep). Snoring sound intensity was measured on a visual analog scale and the partner's short-term satisfaction rate was evaluated after two treatment sessions maximum. Discomfort, pain, and medication intake were compared. RESULTS: Radiofrequency decreased the snoring sound intensity from 7.9 +/- 1.7 to 4.4 +/- 2.7 (P < 0.0001). The four radiofrequency generators had a statistically comparable efficacy. The Ellman generator caused less discomfort and required less anti-inflammatory drugs. CONCLUSION: Despite different technical characteristics, the four generators had a comparable efficacy with good safety. The Ellman generator induced the least discomfort. |
