Congenital pharyngolaryngeal band: report of an unusual case of respiratory distress.
Congenital pharyngolaryngeal band (PLB) is an extremely rare congenital abnormality, characterized by a fibrous web extending from the nasopharynx to the epiglottis. We report a case of unilateral pharyngolaryngeal band in a new-born who presented severe airway obstruction and feeding difficulties. The band extended from the right postero-inferior part of the nasopharynx to the right lateral margin of the larynx. Faucial pillars and tonsil were absent on this side. Endoscopic and radiological assessments excluded associated cervicofacial abnormality. Two endoscopic laser resection procedures were necessary to liberate the larynx from PLB. Clinical and radiological assessment advocated a second pharyngeal pouch development failure as the origin to PLB.
