Videorentgenocinematographic examinations of swallowing were conducted on 81 patients after partial laryngectomy and on 35 subjects being a control group. Resection of piriform recess, a part of base of the tongue, the hyoid bone or its part is the factor that causes intensified difficulty during swallowing and increase in the frequency of the occurrence of aspiration. The results of videorentgenocinematographic examinations indicate that the shape and mobility of the tongue and the mobility of remaining after the surgery parts of the larynx have the greatest influence on the efficient swallowing in patients who have undergone partial laryngectomy due to cancer initially located in the supraglottic area. The larynx mobility is closely related to the remaining of the hyoid bone. The importance of remaining the possibly non-deformed structure and mobility of the tongue during partial laryngectomy involves the issue of reconstruction of defects occurred during the surgery. Videorentgenocinematographic examinations confirm the effectiveness of the method involving reconstruction of defects in a part of the base of the tongue with a vascular pedicle flap of the submandibular gland.
