    Abstract:
    Glottis is a medium level of the larynx, involving the vocal cords, vocal process of arytenoid cartilage, and the anterior and posterior commissures. This region of heterogeneous histomorphological structure has specific characteristics: the internal striated muscles, the outer and inner perichondrium, atypical intra-cartilaginous areas of ossification, and unusual muscular insertion to cartilage. Microtomy of 3 thick successive sections was performed at the level of the upper surface of vocal cords. Standard histological staining methods were used. Microphotographs were taken by light microscope under different magnification along with histomorphometric measurements. Cancer spread is partially restricted by anatomic barriers: vocal ligament and tendon of the anterior commissure, and subsequently by the elastic cone. Easier tumor extension may be due to absence of the internal perichondrium and ossification of thyroid cartilage. Microvascularization of the anterior commissure is significant for tumor spread in glottis and paraglottic space. The role of commissural lymph network in local spread of the cancer is completely vague. It is certain that there are causes, still unrecognized, which have an effect on the pathways and direction of malignant tumor spread.
