ABSTRACT

Objective To explore the effects of supraglottic laryngeal carcinoma and hypopharyngeal carcino-ma on swallowing functions .Methods The data of 32 patients with supraglottic laryngeal carcinoma (laryngeal car-cinoma group) ,20 patients with hypopharyngeal carcinoma (hypopharyngeal carcinoma group) and 81 cases of nor-mal persons of the same age (50～79) as a control (normal control group) who were diagnosed and treated in our department from 2015 December to 2017 February were evaluated by repeated saliva swallowing test ,watian drink-ing water test ,and endoscopic examination of swallowing .Results In the laryngeal carcinoma group ,we found swallowing dysfunctions in 17 cases(53 .13％ ,17/32) .In the hypopharyngeal carcinoma group ,we found swallo-wing dysfunctions in 15 cases(75 .00％ ,15/20) .For 81 cases of normal persons (normal control group) ,there were swallowing dysfunctions in 11 cases(13 .58％ ,11/81) .The statistical analysis of the laryngeal carcinoma and hypo-pharyngeal carcinoma groups with abnormal swallowing functions were significantly higher than the normal control group (P<0 .001) .In the laryngeal carcinoma group ,according to the anatomic site ,the tumors were divided into two groupsfrom 21 cases of epiglottis and fringe group ,we found swallowing dysfunctions in 14 cases (66 .67％ , 14/21);out of 11 cases of ventricular bands + laryngeal ventricle group , swallowing dysfunctions in 3 cases(27 .27％ ,3/11) .The differences between the two groups were significant (P<0 .05) .In the hypopharyngeal carci-noma group ,out of 14 cases of pyriform sinus ,swallowing dysfunctions were in 10 cases(71 .43％ ,10/14);out of 6 cases of posterior hypopharyngeal wall carcinoma ,swallowing dysfunctions in 5 cases(83 .33％ ,5/6) .The differ-ences between the two groups were insignificant (P>0 .05) .Conclusion Supraglottic laryngeal carcinoma and hypo-pharyngeal carcinoma all have effects on swallowing functions and increase the incidence of dysphagia .In the supra-glottic laryngeal carcinoma ,the primary tumor location has influence on the swallowing functions .
