Imaging study of maxillary sinus in normal adults using cone-beam CT / 中国耳鼻咽喉头颈外科

ABSTRACT

[ABSTRACT]OBJECTIVETo estimate different dimensions of maxillary sinus measured on cone-beam computerized tomography (cone-beam CT), and determine the differences in side and gender.METHODScone-beam CT image data from 200 normal adults was selected and analyzed by Invivo Dental software. The craniocaudal diameter, anteroposterior diameter, width and volume of maxillary sinus were measured as well as the thickness of the orbital floor. Statistical analysis was performed with SPSS 11.5.RESULTSThere were no statistically significant differences in the craniocaudal diameter, anteroposterior diameter, width and volume of maxillary sinus between sides (P>0.05, respectively). Significant differences were noted in the craniocaudal diameter and volume of bilateral maxillary sinus and the width of right maxillary sinus based on gender (P0.05, respectively).CONCLUSIONOur findings indicate that cone-beam CT can be used to measure different dimensions of maxillary sinus and provide imaging anatomical data for clinical treatment.
