|Abstract ||:||We found few studies on the association between maxillary sinus size and malocclusion in an electronic search using PubMed. The purpose of this study was to investigate maxillary sinus size in different malocclusion groups and the association between maxillary sinus size and dentofacial morphology by the use of lateral cephalometric radiographs. A total of 120 lateral cephalograms were used. These radiographs were derived from subjects with skeletal class I, class II, and class III malocclusions, classified on the basis of the A-N-B angle. Each malocclusion group consisted of 20 boys and 20 girls ranging in age from 12 to 16 years. Two linear measurements and three area measurements were made to evaluate maxillary sinus size, and four angular and eigh linear measurements were made to evaluate dentofacial morphology. Analysis of variance and Pearson’s correlation analysis were performed for statistical comparison. The maxillary sinuses showed no significant differences in size between the different classes of skeletal malocclusion or between sexes. However, the maxillary sinus measurements were significantly correlated with several dentofacial morphological measurements. When formulating an orthodontic treatment plan, orthodontists should take into consideration the fact that the patients 12 to 16 years old with large cranial bases and nasomaxillary complexes tend to have larger maxillary sinuses, but there is no significant association between maxillary sinus size and the A-N-B angle denoting the sagittal skeletal jaw relationship.|
