The Nomenclature Committee of the European Laryngological Society taken the personal classification used by various members were analyzed and integrated into a common format. Thus, a new classification (Remacle et al., 2000) end next modification (Remacle et al., 2007) in was proposed and accepted by the members. This nomenclature takes into account both the histological and anatomical extent of surgery, and groups it into several categories. Subepithelial cordectomy- excision of the epithelium and the superficial layer of the lamina propria. Subligamentous cordectomy- excision of the epithelium, Reinke's space, and vocal ligament is undertaken. Transmuscular cordectomy- resection consists of the epithelium, lamina propria, and part of the vocal fold muscle, and may extend from the vocal process to the anterior commissure. Total or complete cordectomy-excision extends from the vocal process to the anterior commissure. Anteriorly, the incision is made at the anterior commissure. Type Va extended cordectomy - includes the anterior commissure and contralateral vocal fold, if necessary. In type Vb extended cordectomy, the excision is extended to remove part or all of the arytenoids. The posterior arytenoids mucosa is preserved. In Type Vc extended cordectomy, the whole of the ventricle and the ventricular fold is removed together with the vocal fold. In Type Vd extended cordectomy, surgery is extended inferiorly to include the subglottic mucosa Type VI cordectomy - Anterior billateral cordectomy in this operation surgical intervention is focused on anterior commissure, therefore some authors name it commissurectomy.
