The clinical findings implicated choanal stenosis as the immediate cause of obstruction in one infant, obstructive lymphoid tissue in the second, and a laryngeal web in the third.

Readers of the above report should be reminded of another entity in which there is midfacial hypoplasia and which may be complicated by upper airway obstruction, namely, Down's syndrome. Rowland et al² reported a case of cor pulmonale due to chronic upper airway obstruction in a 5-year-old child with Down's syndrome.
