title: [Role of sophisticated radiological technics in the diagnosis of lacrimal fistulas].
abstract: Lacrimal fistulae are rare and not well known by radiologists. Four cases are illustrated, two congenital (a skin-canaliculous and a canaliculous-palpebral fistula) and two acquired (a rare case of sac-orbital fistula and a canaliculous-palpebral fistula arisen during dacryography). Fistulae are to be distinguished from pedunculated lacrimal diverticulous of which an interesting and rare case is presented. After a careful examination of the pathogenesis and symptomatology of lacrimal fistulae the authors agree that only macrodacryography carried out by means of sophisticated techniques (seriography, magnification, subtraction) enables a precise demonstration of the originating point, of the course and outlet (cutaneous and internal) and provides therefore indispensable data for surgery.
