Cricothyroidotomy is a surgical procedure involving penetration through the skin and cricothyroid membrane to maintain airway patency during life-threatening emergency conditions. Complications such as bleeding and laryngeal stenosis can result from it. Our aim in this study was to identify the anatomical structures located on the membrane and to ascertain whether there is a safe area on the membrane for this procedure. ⋯ Needle puncture or cannulation through the lower right quadrant of the cricothyroid membrane will injure fewer anatomical structures so there should be fewer complications due to degradation of the vascular supply to this region.
