A<unk>  is the surgical removal of all or part of the tongue. It is performed in order to curtail malignant growth such as oral cancer. Often only a portion of the tongue needs to be removed, in which case the procedure is called a partial removal, or hemiglossectomy. A midline<unk>  is a surgical reduction of the size of the base of the tongue (posterior tongue), sometimes used to treat sleep apnea.
