and a special needle-like electrode with an insulating sleeve covering all but the tip, that delivers RF energy under the surface of the tissue. The electrode is used to administer controlled, low-power RF energy to create coagulative (clotting) lesions, where tissue is denatured, beneath the mucosa (lining) of the targeted areas:

and other airway structures are targeted
''Note: the actual areas targeted depends on each individual's specific anatomy, so the above are just general associations.''
After 6–8 weeks, the lesions are naturally resorbed as the necrotic tissue is swept away and the surface sinks to fill the void, which reduces the volume of the tissue while stiffening what remains. When this occurs the airway is enlarged, allowing a less-restricted flow of air. In addition, the scar tissue at the margins of the lesion is relatively firm and less inclined to contribute to snoring. Several follow-up treatments are usually required to obtain the desired results. Most insurance companies do not cover somnoplasty since it is not a widely accepted treatment for sleep apnea.
