Frame 1: Submucosal Delivery of RF Energy

The patient is fully awake throughout the treatment. The physician first applies a local anesthetic to the uvula and palate, similar to that used in a dental procedure. A few minutes later the Somnus device, which is connected to a radiofrequency generator, is placed into the mouth. A small electrode located at the end of the device is inserted into the soft palate. Radiofrequency is applied through the electrode. Part of the electrode is insulated to protect the delicate surface of the tissue. Through controlled delivery of radiofrequency energy, the tissue is heated in a limited area around the electrode. The patient does not feel discomfort during the procedure.

Frame 2: Creation of Coagulative Lesion

The procedure creates a submucosal lesion in the soft palate. Patients typically experience some swelling and have a mild sore throat. Following the Somnoplasty procedure, most patients take an over-the-counter analgesic for one to three days.

Frame 3: Tissue Volume Reduction

Over a period of three to six weeks the lesion is naturally resorbed by the body, leading to tissue volume reduction. In addition, the collagen in the treated area tends to contract, lifting the uvula, stiffening the tissue and reducing its propensity to vibrate. With the reduction and tightening of the obstructive tissue, snoring is reduced in many patients.
