Abstract
A prospective pilot study was conducted to investigate the efficacy of radiofrequency thermal ablation (RFTA) of the soft palate to treat simple snoring. Ten consecutive, consenting patients were recruited following history, examination, Epworth scoring, sleep nasendoscopy and full polysomnography. All the patients received two treatments of three lesional RFTA of the soft palate under local anaesthesia, using the Somnus S2 generator. Each treatment was separated by 6 weeks. Patients completed a questionnaire which used visual analogue scales to score pain during the procedure as well as the postoperative period. Snoring was also scored on visual analogue scales by both the patient and the partner. Objective assessment was based on full polysomnography 3 months after the second treatment. Sixty per cent of patients subjectively reported improvement in snoring. Objectively, only 30% showed improvement in duration of snoring (38-48% better) with no change in intensity. There was high patient acceptability of the procedure.
