Abstract
Abstract A method for debulking the tongue provides an ablation apparatus including a source of electromagnetic energy and one or more electromagnetic energy delivery electrodes coupled to the electromagnetic energy source. At least one electrode is advanced into an interior of the tongue. Electromagnetic energy is delivered from the electrode to debulk an interior section of the tongue without damaging a hypoglossal nerve. The electrode is then retracted from the interior of the tongue.
