[Disturbances in development of the maxilla following interstitial radium therapy for a facial rhabdomyosarcoma at the age of 3 years (author's transl)].

Radium therapy at the age of 3 years for an embryonic rhabdomyosarcoma of the paranasal fold resulted in severe cutaneous lesions but also relatively limited disturbances of growth of the corresponding maxilla: inclusion of the underlying canine and version of neighbouring teeth, very incomplete development of the nearest dental roots, absence of air filling of the maxillary sinus. The relatively slight nature of these developmental disturbances is certainly related to the techniques of interstitial radium therapy developed and used at the Gustave Roussy Institute. Routine orthodontic study of the cases of children surviving after treatment of a malignant tumor of the face would undoubtedly offer even more precise information concerning therapeutic indications.
