Submucosal ablation of the tongue base is a medical procedure that utilizes radiofrequency tissue ablation (RFTA) to reshape and reduce the base of the tongue. This technique is particularly relevant for patients suffering from obstructive sleep apnea, a condition that can be exacerbated by hypertrophy, or enlargement, of the tongue base. The procedure is performed at one or more sites within the tongue base, aiming to alleviate airway obstruction caused by the enlarged tissue. During the procedure, a radiofrequency electrode is carefully inserted through the chin and advanced into the base of the tongue, ensuring that the mucosa is not punctured. Once in position, the electrode is activated to generate a thermal lesion that is confined entirely within the muscular layer of the tongue. This method allows for precise control over the size and shape of the lesions created, as the electrode can be repositioned and activated at multiple sites along the tongue base. It is important to note that multiple treatment sessions may be necessary to achieve optimal results, and each session is reported separately for coding and billing purposes.
