Abstract

Introduction: Both maxillofacial surgery and orthodontic procedures must take the maxillary sinus extension into consideration. Several software imaging packages have reported the ability to calculate the maxillary sinus's volume. This work aim was to compare two software imaging packages for measuring the maxillary sinus volume in different sagittal skeletal position of the maxilla. Material and Methods: A total of 90 CBCT scans were examined. Patients were divided into 3 groups according to their maxilla sagittal skeletal position into: normal maxilla group, prognathic maxilla group, and retrognathic maxilla group. The volume of the maxillary sinus on both the right and left sides were measured in each group using two different software programs: thePlanmeca Romexis and OnDemand 3D software. The imaging exams were imported to the software after being converted to DICOM files. After two weeks, the same operator repeated the measurements, and the reliability tests employed the intraclass correlation coefficient. Results: For the two programs, the intraclass correlation coefficients showed high repeatability. The software used to calculate the maxillary sinus volume on the left and right sides did not show any appreciable changes. There was no statistically significant difference between the maxillary sinus volumes of the various skeletal groups. Conclusion: Upon measuring the volume of both the right and left maxillary sinus using the Planmeca Romexis and OnDemand3D software programs no significant differences were found.
