[The assessment of compensatory mechanisms improving pharyngeal phase of deglutition after partial supra-cricoid laryngectomy. Computer tomography analysis of x-ray images].
Different compensatory mechanisms after supracricoid laryngectomies of CHP and CHEP type have been observed. Wide surgical resection of anatomical structures lead to situation where laryngeal protection of lower respiratory pathway is removed. After such wide resections the lower respiratory pathway is protected against food by so called "upper closure" i.e. high placement of remaining part of the larynx and surgical movement of basis of the tongue or the tongue with epiglottis above the plane of entrance into lower respiratory pathway. Uppermost placement of the remaining laryngo-tracheal complex has been achieved by using a stabilising suture attaching trachea to sternal aponeurosis. Here, the mechanisms that protect the lower respiratory pathway and make easier pharyngeal phase of the deglutition are described.
