title: Congenital fistula of the apex of the pyriform sinus: an overlooked phenomenon of debatable origin.
abstract: Fistula of the pyriform sinus apex is an often overlooked entity which generally manifests itself as acute suppurative thyroiditis or recurrent deep neck abscesses in children or young adults. Two cases are reported. Arguments in favor of a fourth pharyngeal pouch origin are stressed and the surgical management is described.
