[Two cases of laryngotracheal stenosis in children suffering from punctate epiphysis disease (author's transl)].

The authors report two cases of congenital laryngotracheal stenosis in children with punctate epiphysis disease. This rare condition manifests itself clinically by dwarfism of the extremities, saddle-shaped deformity of the nose, cataract and visceral lesions. The specific common feature is the presence of radiological calcifications in bones with chondral ossification. Laryngeal or tracheal localisations are rare. They may be associated with laryngotracheal stenosis. On the basis of these two cases and of eight other found in the recent literature, the authors attempt to define the relationship of such stenosis with the existence of laryngotracheal calcifications and to define their prognostic significance in the course.
