Title: Radiographic Assessment of Foramen Rotundum by CBCT Imaging Technique
Abstract: Objective: To assess the anatomical features of foramen rotundum(FR) in normal adult persons.Methods: Data of anatomy relating the FR was examined and obtained by CBCT scans of 200 normal Chinese persons.Results: Three types of position related to the FR and the sphenoid sinus were discovered: ① FR obviously within the sphenoid sinus;②FR partly within the sphenoid sinus;③FR outside the sphenoid sinus.In the sagittal plane,three pathways were observed: ①FR travelled in an anterior-inferior direction;②FR travelled in an anterior-posterior direction,parallel to the axial plane;③FR travelled in an behind-inferior direction.In the oblique axial plane or the axial plane,three pathways were observed: ① FR travelled from anterior-external to behind-inside;② FR travelled in an anterior-poster direction,parallel to level plane;③FR travelled from anterior-inside to behind-external.In the sagittal plane,the length of FR was(6.91 ±1.51) mm,while the diameters of its anterior and posterior opening were(3.35 ±0.61) mm and(3.28 ±0.60) mm respectively.In the cross-sectional plane,the length of FR was(6.83 ±1.76) mm,while the diameters of its anterior and posterior opening were(3.50 ±0.76) mm and(3.25 ±0.45) mm respectively.The distance between the greater palatine foramen and the FR was(34.91±2.31) mm.Conclusion:CBCT provides high quality images if we use small field of view,and may play an important role to improve the clinical performance.
