Sample Questions

Question 1
A newborn in the NICU has episodic cyanosis relieved by crying. Flexible fiberoptic examination cannot pass a 6-French catheter through either nasal cavity. Which is the diagnosis and which syndrome should be considered?
Bilateral choanal atresia; evaluate for CHARGE syndrome (CHD7 mutation)
Laryngomalacia; isolated finding
Subglottic stenosis; acquired
Tracheoesophageal fistula; isolated esophageal issue
Question 2
A 3-month-old presents with inspiratory stridor worse when supine and during feeding, present since 2 weeks of life but without cyanosis or failure to thrive. Flexible laryngoscopy shows short aryepiglottic folds, omega-shaped epiglottis, and supraglottic collapse on inspiration. Diagnosis?
Laryngomalacia — most common cause of congenital stridor; usually resolves by 12-18 months
Vocal cord paralysis
Subglottic stenosis
Laryngeal cyst
Question 3
An ex-premature infant previously intubated for 3 weeks presents with biphasic stridor. Airway endoscopy confirms subglottic stenosis with 60% luminal narrowing. Per the Myer-Cotton grading system, this is:
Grade II (51-70%)
Grade I (≤50%)
Grade III (71-99%)
Grade IV (no detectable lumen)
Question 4
A 4-year-old with severe Myer-Cotton Grade III subglottic stenosis presents for definitive airway reconstruction. Which surgical option is most appropriate for complete circumferential severe SGS?
Cricotracheal resection (CTR) — en bloc resection of the stenotic cricoid segment with primary thyrotracheal anastomosis
Tracheostomy without reconstruction
Balloon dilation alone
Observation
Question 5
A 2-year-old with complete tracheal rings and pulmonary artery sling has long-segment tracheal stenosis (>30% of trachea). Which procedure is preferred for this anomaly?
Slide tracheoplasty — reduces tracheal length but doubles the diameter; preserves airway continuity and provides mature airway without foreign material
Total tracheal resection with end-to-end anastomosis only
Tracheal transplantation
Indefinite tracheostomy
