An awake nasal laryngoscopy was performed in clinic without the nasal trumpet that showed redundant pharyngeal tissue with significant nasopharyngeal and oropharyngeal crowding (Figure 2(a)). Repeat laryngoscopy with the trumpet showed open hypopharynx with the trumpet tip just above the epiglottis, completely bypassing the obstructed segment (Figure 2(b)).
