Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Cone Beam Computed Tomography (CBCT) has been used to assess the volume of the maxillary sinus using the manual and semi-automatic segmentation. The majority of researches stressed on the reduced accuracy of the automatic segmentation when compared to the real volume. Regarding the semi-automatic segmentation, there are researches assessed the volumetric measurement of the maxillary sinus and they reported that there is no significant difference between semi- automatic and the manual segmentation in CT.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Automatic segmentation is believed to be less time consuming and more accurate in assessment of structures with regular border but fairly assessed the structures with irregular border like paranasal sinuses. The semi-automatic software is efficient and accurate as manual tracing with significant reduction in inter-observer variability and time . On the other hand, all neighboring contacting voxels located within a defined range (threshold) of similar HU values of different adjacent tissues may be measured so over calculation or under calculation could be suspected
