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

Abstract

Objective:No study has investigated the relationship between maxillary sinus findings and skeletal malocclusion based on conebeam computed tomography (CBCT). The aim of the present study was to determine the relationship between the frequency of sinus findings and patients’ skeletal malocclusion classification.Objective: No study has investigated the relationship between maxillary sinus findings and skeletal malocclusion based on conebeam computed tomography (CBCT). The aim of the present study was to determine the relationship between the frequency of sinus findings and patients’ skeletal malocclusion classification.Methods:A total of 105 CBCT scans were examined and divided into three groups according to skeletal classification. Two experienced observers reviewed the CBCT images and recorded all the maxillary sinus findings. The patients’ skeletal malocclusion, thickness of the Schneiderian membrane, and pathological sinus findings were evaluated.Results:The sinus findings were classified into four groups: 0=no finding, 1=mucosal thickening, 2=partial opacification with liquid accumulation, and 3=total opacification. Statistical analysis showed that there was no correlation between the skeletal malocclusion and pathological sinus findings. However, there were significant differences in the Schneiderian membrane thickness between the groups.Conclusion:The Schneiderian membrane thickness was significantly different in Class II and Class III patients. There was no relationship between pathological sinus findings and skeletal malocclusions.
