Abstract

Aim: The anatomic measurements of the thyroid cartilage, which is an important part of the laryngeal roof, were calculated using computed tomography (CT) and the data obtained were compared in two groups of male and female.
Material and Methods: A total of 148 adult patients were examined in this retrospective, cross-sectional study. All the patients were aged over18 year and presented to emergency ward between 2015 and 2016 due to trauma. Cervical vertebra CT was taken and the reformatted two-dimensional images were examined. Measurements were taken on the images at two separate levels of the interlaminar angle (ILA), thyroid prominence angle and the distance of the vocal cords from the lower edge of the thyroid.
Results: The ILA in the glottis region was measured as 74.02°±17.23° for males and as 98.00°±12.78° for females. The difference between the genders was statistically significant (p
