Cricothyroidotomy and the anatomy of the cricothyroid space. An autopsy study.

Airway management is one of the main dictums in anaesthesia, emergency medicine and critical care. Endotracheal intubation, tracheostomy and cricothyroidotomy are all approved methods to secure a patient's airway. Cricothyroidotomy is performed in the space between the anterior inferior border of the thyroid cartilage and the anterior superior border of the cricoid cartilage. We studied 107 autopsies with special interest in the anatomy of the cricothyroid space.
