摘要
目的:应用CBCT测量青海地区成人上颌窦外侧骨壁的厚度,为与上颌窦外侧骨壁相关的手术提供指导方案和风险因素评估,避免手术并发症的发生。方法:选取300例成人研究对象的CBCT影像资料,测量分析上颌窦外侧骨壁厚度。采用SPSS 17.0软件进行统计学分析。结果:300例研究对象中,上颌窦外侧骨壁平均厚度在上颌第二前磨牙区(P2)、上颌第一磨牙区(M1)和上颌第二磨牙区(M2)分别为(1.48±0.59)mm,(2.14±1.19)mm和(1.65±1.10)mm;左右侧上颌窦外侧骨壁厚度在P2、M2区存在显著性差异(P<0.05);不同性别间上颌窦外侧骨壁厚度在P2和M1区存在统计学差异(P<0.05),男性厚度大于女性;不同年龄组之间,M2区上颌窦外侧骨壁厚度有显著性差异(P<0.05);缺牙情况与上颌窦外侧骨壁厚度无相关性。结论:青海成人上颌窦外侧骨壁的厚度在上颌第二前磨牙区最薄,左右侧及不同性别、年龄之间存在差异。
Objective:The purpose of this study is to analyze maxillary sinus lateral wall thickness(LWT)by using cone-beam computed tomography(CBCT)in order to provide the importance of evaluating the LWT for the operation guidance and preoperative risk assessment,avoiding the complications during surgery.Methods:The cone-beam CT scans of 300 adult subjects were evaluated to measure the maxillary sinus lateral wall thickness.The data was analyzed by SPSS 17.0 software.Results:Among the 300 subjects,the mean thickness of maxillary sinus lateral wall lay at the second premolar(P2)and the first molar(M1)and the second molar(M2)were(1.48±0.59)mm,(2.14±1.19)mm and(1.65±1.10)mm.The thickness of maxillary sinus lateral wall was significantly different from each side at P2 and M2(P<0.05).Significant differences of gender were indicated at P2 and M1(P<0.05),while the thickness in men were thicker than that in women.The thickness of maxillary sinus lateral wall at M2 were significantly different between different age groups(P<0.05).There was no significant association between maxillary sinus lateral wall thickness and presence or absence of teeth.Conclusion:There are differences of the thickness of maxillary sinus lateral wall in population of Qinghai region with respect to position,sex,age and different subjects,among whom the thinnest region is at the P2 region.
