**Core Concept:** Tracheal stenosis is a narrowing of the trachea, leading to airway obstruction and respiratory distress. It can be caused by trauma, infection, or scar tissue. Tracheal stenosis management involves addressing the underlying cause and ensuring adequate airways patency.

**Why the Correct Answer is Right:**

The correct answer, **C. Tracheostomy and stent placement**, is chosen due to the severe tracheal stenosis causing significant respiratory distress despite previous hospitalization and mechanical ventilation. Tracheostomy involves creating a surgical opening in the neck, providing an alternative airway route. A stent is then placed in the trachea to maintain the airway patency and prevent further narrowing.

**Why Each Wrong Option is Incorrect:**

A. **Orotracheal intubation:** Although intubation is a life-saving procedure, in this case, it has been done for 2 weeks and has not resolved the severe tracheal stenosis.

B. **Medical management:** Tracheal stenosis does not improve with medical interventions alone, and surgical intervention is necessary for severe cases.

D. **Symptomatic management only:** This option does not address the severe tracheal stenosis causing respiratory distress and would not be a suitable management approach.

**Clinical Pearl:**

In cases of severe tracheal stenosis, timely surgical intervention (tracheostomy and stent placement) is crucial to prevent respiratory compromise and ensure successful long-term airway management. This approach addresses both the airway obstruction and maintains airway patency. Tracheostomy and stent placement should be considered when conservative measures fail, as in this case, to prevent further respiratory deterioration and ensure adequate ventilation.
