Tonsillectomy and Adenoidectomy is simultaneous removal of the tonsils and the adenoids. Tonsillectomy is a procedure in which the tonsils (groups of lymphoid tissue) are removed from the back of the throat. The surgeon will remove the tonsils using one of a variety of methods that can include radiofrequency ablation, harmonic scalpel, traditional scalpels, laser, or any other technique that will remove the tonsils in the most appropriate manner possible. The adenoids are groups of tissue located behind the nasal area. If the adenoids are also inflamed or are interfering with breathing, they will be removed along with the tonsils.
