What is the procedure that an incision is made through the anterior tracheal wall and a tube is inserted?

The procedure you are referring to is called a tracheostomy. It involves making an incision through the anterior wall of the trachea to create an opening, allowing for direct access to the airway. A tube is then inserted into this opening to facilitate breathing, particularly in patients with obstructed airways or those requiring long-term ventilation support. This procedure can be performed as an emergency intervention or as a planned surgical operation.
