Palatoplasty for snoring: a randomized controlled trial of three surgical methods.

In a randomized, controlled trial, 62 patients (47 men and 15 women) with severe antisocial snoring, but no sleep apnea, were allocated to one of three surgical treatments. These were uvulopalatopharyngoplasty, laser palatoplasty, and diathermy palatoplasty. Postoperative morbidity was measured on a visual analogue scale of severity of pain, dysphagia, and nasal regurgitation at 1, 2, and 7 days after the operation. Efficacy of each procedure was measured by asking the sleeping partner to record the severity of snoring before and after the operation, again on a visual analogue scale. Measurements were taken at 1, 3, and 6 months. There were no significant differences in early postoperative morbidity among the treatment groups. Diathermy palatoplasty is a new technique for the relief of snoring that is associated with low morbidity and requires little in the way of expensive equipment.
