Radiofrequency Assisted Uvulopalatoplasty (RAUP) is a highly successful procedure to help your snoring. In RAUP, the vibrations of the soft tissues (palate) which cause snoring are reduced. A device using radiofrequency waves is inserted into the palate in several places. During the healing process, the normal tissue is replaced by a small amount of scar tissue. This new tissue is smaller and firmer; therefore, the vibrations of the palate are lessened and snoring is improved. This technique is called Radio Frequency Tissue Ablation (RFTA).
