Long-term results of radiofrequency volumetric tissue reduction of the palate for snoring.

To assess the long-term efficacy and morbidity of radiofrequency volumetric tissue reduction (RFVTR) of the soft palate for snoring, we examined the medical records of 39 patients who received this treatment at an academic medical center. Telephone interviews were conducted with the patients to evaluate the long-term subjective efficacy and sequelae. The average follow-up was 14 months (range, 3 to 26 months). Twenty-eight patients (72%) responded to treatment, defined as a 4-point decrease on a 10-point scale. The self-reported snoring score decreased an average of 52% (8.8 +/- 1.9 to 4.2 +/- 2.9). Sixty-seven percent of the patients were satisfied. The response to treatment did not always correlate with patient satisfaction. The snoring relapse rate was 11% among responders. No significant differences were identified between responders and nonresponders. No significant complications or long-term sequelae were observed. We conclude that RFVTR of the palate is a relatively safe and effective long-term treatment for snoring. Defining realistic pretreatment expectations is important in maximizing patient satisfaction.
