[Analysis of pharyngeal phase of swallowing after supracricoid partial laryngectomy with cricohyopexia (CHP) and cricohyoepiglottopexia (CHEP)].

The analysis of efficiency and timing of pharyngeal phase events after supracricoid reconstructive laryngectomy was presented. Material consist of 15 patients after partial laryngectomy with cricohyopexia (CHP) and 19 with cricohyoepiglottopexia (CHEP) in average age of 53 (41-66) years. The video-radiographic examination of swallowing was done in the early period (max. 120, average 72 days) and in the late period (min. 10, average 24 months) after surgery. The larynx closure improved and the wide of upper oesophageal sphincter (UES) increased in the late period comparing to first examination. The duration of UES relaxation and the duration of pharyngeal phase were similar to physiological status but the time of larynx closure was longer in both periods.
