What is crycothyroid membrane?

The cricothyroid membrane is a small, thin and elastic membrane that lies between the cricoid and thyroid cartilages of the larynx. It is located at the top of the trachea and can be easily felt with your fingers. The cricothyroid membrane plays a crucial role in airway management as it is the site for emergency airway access during a surgical or medical emergency.

In emergency situations where the upper airway is obstructed, the cricothyroid membrane provides an alternative airway for ventilation by performing a cricothyrotomy (or cricothyroidotomy). This is a procedure whereby a small incision is made through the cricothyroid membrane and an airway tube is inserted to facilitate breathing.

The cricothyroid membrane is also important during endotracheal intubation procedures in which a tube is inserted through the mouth into the trachea to provide an airway. If the tube does not pass through the vocal cords correctly, the cricothyroid membrane can be used as an alternative intubation site.

Overall, the cricothyroid membrane is a vital part of the airway anatomy that can be lifesaving in emergency situations.
