Primitive pharyngeal dyskinesia associated with upper airway collapse in an infant.

We report a case of total collapse of the upper pharyngeal airway in a slightly premature baby, resulting in a noisy breathing disorder. Primary immaturity of the central nervous system contributing to pharyngeal muscle hypotonia has been implicated in association with the increase in nasal pressure. The infant experienced complete resolution of symptoms a few weeks after the placement of a nasopharyngeal tube. This case report demonstrates the difficulty in diagnosis and management. The developmental spectrum and exploration are reviewed.
