A morphometric analysis of laryngeal anatomy: A cadaveric study

Objectives: This study aims to describe morphometric measurements of the laryngeal framework and discuss their implications forphonosurgery among Turkish subjects.Patients and Methods: Larynges from 40 male and 20 female fresh cadavers were extracted during autopsy in a forensic scienceinstitution between January 2015 and December 2015. Measurements were taken of the length of membranous and cartilaginousvocal fold (mVF, cVF), width and thickness of VF (wVF, tVF), anterior and posterior subglottic distance (AS, PS), width and height ofthyroid cartilage (wTC, hTC), and distance between projection of anterior commissure to thyroid cartilage inferior border (pAC to TIB).Results: For all parameters, median and mean values were higher in male groups, but the differences were significant only inpAC to TIB, wTC, cVF and mVF groups (p
