Objective  To compare the efficacy of single-stage, multilevel, temperature-controlled radiofrequency tissue volume reduction (TCRFTVR) for the soft palate and base of the tongue with that of nasal continuous positive airway pressure (CPAP) in primary treatment of mild to moderate obstructive sleep apnea.

Design  A prospective nonrandomized clinical study.

Setting  Tertiary care referral center.

Patients  Data from 47 patients with mild to moderate obstructive sleep apnea treated between January 1, 2003, and October 31, 2006, were reviewed.

Interventions  Twenty-six patients underwent TCRFTVR and 21 underwent nasal CPAP as a primary treatment modality.

Main Outcome Measures  Baseline and 12-month posttreatment measurements using the Epworth Sleepiness Scale and polysomnography were compared.

Results  The baseline characteristics of the groups were not significantly different. Both methods showed meaningful results for the Epworth Sleepiness Scale and polysomnography variables 12 months after treatment compared with baseline measurements. The results were not significantly different in the posttreatment intergroup comparisons. Treatment success rates were 52.4% for nasal CPAP and 53.8% for TCRFTVR (P = .92).

Conclusion  Similar comparison results with nasal CPAP in objective and subjective variables make single-stage, multilevel TCRFTVR a good alternative in primary treatment of mild to moderate obstructive sleep apnea.
