Resulting from the rough flow of air through the nose and throat during sleep, snoring can arise from transitory obstruction at various levels, rendering the sufferer feeling sleep deprived. A relatively new method using radiofrequency technology, called palatoplasty (somnoplasty), can be used to reduce the size of obstructive tissues in the nose and throat. In this study, we assess radiofrequency palatoplasty in the treatment of snoring. Methods: This nonrandomized prospective

Snoring and drowsiness were each subjectively scored using 20-point visual analogue scales before and after treatment. Radiofrequency energy was delivered to the soft palate either at the midline or in the lateral soft palate; 21 patients were treated once and seven patients twice with an interval of at least seven weeks. Results: The mean age of the patients was 47 (SD=10.7) years, with a range of 25-65 years, 57% were men, and the mean body mass index was 29 (SD=4.5). Sleep apnea in these patients was subjectively rated mild to moderate. After seven weeks of treatment, snoring was improved in 71.4% of patients (p<0.005). The tongue versus pharyngeal size was improved in 34.4% (p<0.005). The mean patient snoring score was significantly improved from 17.39 (SD=3.02) to 11.50 (SD=6.46) (p<0.005). The mean drowsiness score was also significantly reduced from 6.8 (SD=6.9) to 3.93 (SD=4.19) (p<0.005). No persistent negative impact was observed in speech or swallowing. Pain and bleeding was limited. Conclusions: Radiofrequency palatoplasty is effective in the treatment of snoring and its consequent drowsiness.
