摘要
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:①FR 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:①FR travelled from anterior-external to behind-inside; ②FR 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.关键词
