Pharyngeal and pharyngolaryngeal bands: report of an unusual combination of congenital anomalies.

Multiple abnormal pharyngeal and pharyngolaryngeal bands were present in a child presenting with diffuse interstitial pulmonary fibrosis. The soft palate was fused to the posterior pharyngeal wall. Instead of there being facial pillars, a muscular band on either side extended from the base of the tongue to the lateral pharyngeal walls. There was neither tonsil nor adenoid tissue present. The epiglottis was tethered to the posterior pharyngeal wall by bands from its lateral aspects. The right arytenoid mound was tethered to the posterior wall of the hypopharynx. It is postulated that these arose from a failure of development of the second branchial pouch.
