Correlation Between Maxillary Sinus (Linear and Volumetric Measurements) and Midface Width Using CBCT

The objective of this study will be To assess the correlation of the 2-D and volumetric maxillary sinus dimensions with the linear measurement of the mid-face width in adult Egyptian individuals. The data collection will be obtained from the data base available at the department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Cairo University. CBCT images will be obtained from Egyptian patients who were referred to the CBCT unit in oral and maxillofacial radiology department for different purposes. The following radiographic examination will be done in Oral and Maxillofacial Radiology Department, Faculty Dentistry, Cairo University. semiautomated segmentation will be performed for the maxillary sinus in both side and then linear and volumetric measurements will be assessed for each sinus. Also the width of midface will be assessed.
