PAEA Surgery End Of Rotation (EOR) Practice Exam

Where is the cricothyroidotomy typically performed?

1. Below the cricoid cartilage

2. At the midline of the thyroid cartilage

3. Between the cricoid and thyroid cartilage

4. Above the hyoid bone

The correct answer is: Between the cricoid and thyroid cartilage

Cricothyroidotomy is a surgical procedure performed to create an emergency airway in cases where intubation is not possible. The correct location for this procedure is between the cricoid and thyroid cartilages. This anatomical location is preferred because it allows for quick access to the airway while minimizing damage to surrounding structures such as the vocal cords and major blood vessels. Performing the incision in this space provides a direct route to the airway, which is critical in emergencies when rapid intervention is required. The cricothyroid membrane, found between the cricoid and thyroid cartilages, is relatively superficial and easy to access, making it the ideal site for this procedure. Other options, such as below the cricoid cartilage or above the hyoid bone, would not provide access to the airway and could potentially cause significant trauma or complications. The midline of the thyroid cartilage is also not the correct location, as it is a part of the airway that contains the vocal cords, making it unsuitable for the procedure meant for emergency airway access.
