Tracheostomy Procedure

# In tracheostomy, the entry into the trachea is through the:
A. Cricoid cartilage
B. First tracheal ring
C. Second and third tracheal ring
D. Fourth and fifth tracheal ring

The correct answer is C. Second and third tracheal ring

In tracheostomy, the entry into the trachea is through 2nd - 4th tracheal rings. Entry through 1st ring results in tracheal stenosis and entry through 5th - 7th rings is very difficult. 

Entry through cricothyroid membrane is called cricothyroidotomy which ia a life saving procedure when endotracheal intubation is not possible.
