Cancer has caused airway stenosis in this patient. — Photos: Dr JAMALUL AZIZI ABDUL RAHAMAN
A silicon stent in place for a patient with tracheal stenosis, a condition that can be caused by prolonged intubation from Covid-19.
The placement of a stent will help enlarge a narrowed airway and allow the patient to breathe better.
