Craniofacial morphology in children with cystic fibrosis.
Cystic fibrosis (CF) is a hereditary metabolic disorder with clinical symptoms of abnormal mucus production. This blocks the airways, gives pancreatic insufficiency, and increases sweat electrolytes. The progressive respiratory disease often leads to respiratory insufficiency and cor pulmonale. The aim of the present investigation was to examine the facial morphology in children with cystic fibrosis. The sample comprised 11 children with cystic fibrosis, who were divided in two groups, one with gastrointestinal disorders and the other with predominantly respiratory insufficiency. Eleven healthy children with normal occlusions were selected as controls. Lateral skull radiographs obtained in natural head posture were digitized, and linear and angular variables for the different groups calculated and compared statistically. The cystic fibrosis group showed open bite, decreased posterior facial height, increased mandibular and craniocervical inclination. Additionally, within the CF-group, the children with respiratory insufficiency differed more from the controls than the children with gastrointestinal disorders. Despite the small number of subjects, the facial morphology of the CF children showed a similar pattern to that of children with nasal respiratory obstruction due to enlarged adenoids or tonsils.
