Surgical tracheostomy
Why are we operating?
A controlled front door into the trachea below an obstruction the mouth cannot bypass, or for the ventilated patient whose tube has outstayed the larynx's welcome.
Indication: Upper airway obstruction, prolonged ventilation, airway protection; elective and controlled wherever possible.
Read the imaging first
Practice before you scrub
The airway reads first
Three days of sore throat, now fever, trismus and a muffled voice. CT neck with contrast. (Fictional educational case.)
- Deep neck sepsis is drained in theatre with the airway secured first: the drainage is the easy half of the operation.
- Stridor, voice change and trismus grade the threat better than the scan alone: trajectory, not appearance, sets the tempo.
The operation in 4 steps
01Position and landmarks
Neck extended, and the midline landmarks are drawn: thyroid notch, cricoid, sternal notch; the incision sits between cricoid and sternal notch.
02Dissection and the thyroid isthmus
Strap muscles are separated in the midline raphe; the thyroid isthmus crossing the trachea is retracted or divided between ties.
03The tracheal window
The trachea is opened at the second to fourth rings, as a window or flap, with stay sutures placed either side.
04Tube insertion and confirmation
The tube is inserted under vision, the cuff inflated, ventilation confirmed with capnography, and the tube secured; the first change is deferred until the track matures.
Anatomy you need
The larynx and the tracheal rings below it: the operation enters between the second and fourth.
