Abstract
Objectives/Hypothesis: To determine the prevalence and the morphometric characteristics of Killian's triangle and to examine their relationship with the anthropometric features of the person. Study Design: Prospective. Methods: The hypopharyngeal wall was examined on 47 human cadavers. After a standardized method of dissection, the muscular structures of the hypopharyngeal wall were demonstrated and the existence or absence of Killian's triangle was determined. The triangle was examined in regard to its morphometric characteristics. In addition, anthropometric examinations of the whole body and of the head and neck regions on these cadavers were done, and the results were compared with the features of Killian's dehiscence. Results: A triangle of Killian was present on 60% (9/15) of the males and on 34% (11/32) of the females. The mean height for the males was 7 mm and for the females 4 mm, and the width was on average 16 mm and 12 mm, respectively. The dimensions of the triangle were correlated significantly with the dimensions of the body and with the length and the descensus of the larynx. Conclusions: The frequency and the dimensions of Killian's triangle appear to be greater in males than in females. Furthermore, the morphometric characteristics of the dehiscence show a correlation with the anthropometric features of the person. These findings can be an explanation for the higher incidence of Zenker's diverticulum with men and for the geographical differences of the diverticulum's frequency. Laryngoscope, 2010Keywords
