Quantitative anatomy of the posterior cricoid region
Folia Morphol 2005;64(4):237-239.
Abstract
The anatomy of the posterior cricoid cartilage region was examined to obtain
a better quantitative understanding of this region. The mean height and width
of the posterior cricoid cartilage in the midline measured 24.5 mm and 25 mm
respectively. The mean distance between the fibres for the left and right posterior
cricoarytenoid muscles was 5 mm at the midpoint of the posterior cricoid
cartilage. The height of these muscles averaged 19 mm for left sides and 20 mm
for right sides. The mean distances from the midpoint and superior midline of
the posterior cricoid cartilage to the inferior laryngeal nerve were 14 mm and
15 mm respectively for left sides and 17 mm and 18 mm respectively for right
sides. It is hoped that these data will be of use to clinicians performing invasive
procedures in this area.
