Abstract
Objective:This study aims to examine the prevalence and the diameter of the bony canal structure of the posterior superior alveolar artery(PSAA)and its relationship to the alveolar ridge by using cone beam computed tomography(CBCT).Methods:CBCT image data of 300 cases with bilateral clear maxillary sinus,that the diameter of the bony canal structure of PSAA and its relationship to the alveolar ridge were observed.Data were presented using descriptive statistics.Results:One hundred and seventy-four patients met the inclusion criteria with 93 male and 81 female,that 276 sides of the maxillary sinus in total.The PSAA was observed in 55.43％(153/276).On the screen of the artery which was first seen,the mean diameter of the posterior superior alveolar foramina was 1.03±0.26 mm,and the mean distance from the artery to the alveolar crest was 19.85±2.18 mm.On the screen of the artery which was last seen,the mean diameter of the posterior superior alveolar foramina was 0.81±0.23 mm,and the mean distance from the artery to the alveolar crest was 17.86±2.25 mm.There was no statistically significant difference in the effect of gender on the detection rate of the bone canal.The mean diameter of the bony canal was significantly smaller in females than that in males,and the difference in the diameters of two points was statistically significant(P＜0.05).Conclusion:The precise information of PSAA could be obtained by CBCT observation before maxillary sinus surgery.关键词
