Abstract:
This author tried to find if the size of the frontal sinus can be used as a diagnostic aid to predict the mandibular growth pattern in growing patients-in lateral cephalogram utilizing the fact the the frontal sinus completes its growth in earlier stage but the mandible continues to grow until later. At this study, the 228 samples were divided into 3 groups as skeletal Class I , II, III malocclusions and three indicies(ANB, APDI, Wits) were measured which hidicate the mandibular body length and the antero-posterior relationship of maxilla and mandible to evaluate their relations with frontal sinus. And results were obtained as followings. 1. The size of frontal sinus is highly related to ANB, APDI, Wits and mandilar body length(p<0.001) 2. the size of the frontal sinus of the Cl III malocclusion group was on the lateral cephalogram larger than Cl I and C1 II group.
