[Functional results of treatment of early carcinoma in the glottic region of the larynx].

Early stage glottic cancer can be successfully treated with open surgery, LASER surgery or radiotherapy. During this treatment the physician obviously has to bear in mind principles of oncological radicality, but also, none the less, the preservation of all the functions of the larynx, and especially the preservation of voice quality. The aim of the study is to compare, in a specifically designed prospective study, the method of treatment with the functional results of basic characteristics of spoken voice of patients with early stage cancer of the glottis region. Then, based on the analysis of the results, to try and determine the most successful method of treatment. The first study group consisted of 72 patients operated using transoral laser microsurgery; the second study group consisted of 75 patients operated using open surgery; and the third study group consisted of 74 patients treated with radiotherapy. The voice quality is much better after laser chordectomy compared to open surgery chordectomy with reconstruction. Furthermore, the functional results of voice quality, after a laser chordectomy, are worse when compared to the group of patients treated with radiotherapy. Taking into account all objective and subjective phoniatric parameters, we determined that there is no crucial difference in the voice quality of patients operated using laser chordectomy and patients primarily treated with radiotherapy. From a functional point of view these two methods are superior to open surgery chordectomy.

[Laser surgery of malignant tumors of the glottic region of the larynx].

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.
