Is There a Relationship Between Maxillary Sinus Findings and Skeletal Malocclusion?

Objective: No study has investigated the relationship between maxillary sinus findings and skeletal malocclusion based on cone-beam computed tomography (CBCT). The objectives of this study were to determine the relationship between the frequency of sinus findings and patients' skeletal malocclusion classification. Materials and Method: A total of 105 CBCT scans were examined and divided into 3 groups according to skeletal classification. Two experienced observers reviewed the CBCT images and recorded all maxillary sinus findings. The patients' skeletal malocclusion, the thickness of the Schneiderian membrane, and the pathologic sinus findings were evaluated. Results: The sinus findings were classified into 4 groups: 0 = no finding, 1 = mucosal thickening, 2 = partial opacification with liquid accumulation, and 3 = total opacification. The statistical analysis showed that there was no correlation between the skeletal malocclusion and pathological sinus findings. However, there were significant dif...
