“…In the randomized comparative study by Blumen et al,35 the Somnus generator induced more prolonged pain than the other three generators (Coblator, Select Sutter, and Surgitron). The Surgitron device was better tolerated in terms of severity and duration of discomfort experienced, and induced a lower steroid intake.…”

“…Most of the SP RFA studies published have been performed with Somnus Medical Technologies devices. We found only one randomized controlled trial comparing devices made by various manufacturers,35 with no evidence on differences in treatment efficacy, suggesting that the choice of a generator cannot be guided by variation in efficacy. Although statistically significant differences were observed in terms of adverse effects, levels of discomfort were extremely low for all the generators.…”

“…Only four of the studies reported the duration of snoring before the treatment decision 12, 14–16. The obstruction site was assessed clinically (with or without endoscopy) in 27 studies,7, 12–36 with the use of cephalometry in four,7, 12, 13, 22 and with sleep endoscopy in three studies 15, 20, 30…”

The review provides evidence that SP RFA is an intervention causing less postoperative pain than others, and the risk of adverse effects for the patient seems to be small. It may reduce symptoms of snoring, at least in the short term. However, most of the published SP RFA literature is based on observational studies with a short follow-up time, which precludes solid conclusions about the effectiveness of the procedure.

“…Many cohort studies and a few randomized controlled trials or clinical controlled trials have compared MIS with a placebo [5]–[9], different energy generators [10], different material rigidity [11], or different operative techniques [12], [13]. RF of the soft palate produces volumetric tissue reduction [14] and selective scar tissue [5] to reduce obstruction and induce stiffness.…”

BackgroundMinimally invasive surgeries of the soft palate have emerged as a less-invasive treatment for habitual snoring. To date, there is only limited information available comparing the effects of snoring sound between different minimally invasive surgeries in the treatment of habitual snoring.ObjectiveTo compare the efficacy of palatal implant and radiofrequency surgery, in the reduction of snoring through subjective evaluation of snoring and objective snoring sound analysis.Patients and MethodThirty patients with habitual snoring due to palatal obstruction (apnea-hypopnea index ≤15, body max index ≤30) were prospectively enrolled and randomized to undergo a single session of palatal implant or temperature-controlled radiofrequency surgery of the soft palate under local anesthesia. Snoring was primarily evaluated by the patient with a 10 cm visual analogue scale (VAS) at baseline and at a 3-month follow-up visit and the change in VAS was the primary outcome. Moreover, life qualities, measured by snore outcomes survey, and full-night snoring sounds, analyzed by a sound analytic program (Snore Map), were also investigated at the same time.ResultsTwenty-eight patients completed the study; 14 received palatal implant surgery and 14 underwent radiofrequency surgery. The VAS and snore outcomes survey scores were significantly improved in both groups. However, the good response (postoperative VAS ≤3 or postoperative VAS ≤5 plus snore outcomes survey score ≥60) rate of the palatal implant group was significantly higher than that of the radiofrequency group (79% vs. 29%, P = 0.021). The maximal loudness of low-frequency (40–300 Hz) snores was reduced significantly in the palatal implant group. In addition, the snoring index was significantly reduced in the radiofrequency group.ConclusionsBoth palatal implants and a single-stage radiofrequency surgery improve subjective snoring outcomes, but palatal implants have a greater effect on most measures of subjective and objective snoring. Multi-stage radiofrequency surgery was not tested.Trial RegistrationClinicalTrials.gov NCT01955083

Comparative study of four radiofrequency generators for the treatment of snoring

Abstract: Despite different technical characteristics, the four generators had a comparable efficacy with good safety. The Ellman generator induced the least discomfort.
