The larynx is an important part of the respiratory system and has great clinical relevance. While many medical procedures involve manipulation or accessing different areas of the larynx, few studies quantify the distances within and between these cartilaginous structures. Our study investigated the size and distance of the hyoid bone, thyroid cartilage and cricoid cartilage and the distances between these structures on human cadavers (n=37). Surprisingly, a significant difference in the size of the cartilaginous structures was not identified in most parameters between genders (p=0.318). However, the distances of the fibrous gaps that lie between the hyoid bone the cartilaginous structures were higher in females than males (p<0.05). Knowledge of this variability has a significant impact on clinical processes like tracheostomies and cricothyrotomies of different genders.
