摘　　要：目的利用锥形束CT(cone-beam computed tomography,CBCT)观察正常上颌窦的解剖形态,评价其与年龄和性别的变化关系,有助于临床医生认识正常上颌窦的解剖结构,在治疗方案的选择上有所预判。方法选择480例患者的CBCT数据,根据年龄分为4组:18~24岁组、25~39岁组、40~54岁组和≥55岁组。将CBCT数据导入Mimics软件中,测量双侧上颌窦体积(maxillary sinus volume,MSV)、表面积,观察上颌窦底(maxillary sinus floor,MSF)的形态,使用SPSS软件分析与年龄和性别的相关性。结果左右侧MSV、表面积差异无统计学意义(P>0.05),男性MSV和表面积均大于女性(P<0.05)。18~24岁组和25~39岁组MSV大于其他两组,且18~24岁组表面积的测量值最大(P<0.05)。性别与MSF形态无显著相关性(P>0.05),而年龄与MSF形态有显著相关性(P<0.05)。结论正常上颌窦的体积及表面积受年龄及性别影响,随着年龄的增长而减少,但左右侧上颌窦的形态对称。Objective To observe the anatomic morphology of the normal maxillary sinus using cone-beam computed tomography(CBCT)and evaluate its variation to age and gender, helping clinicians to understand the anatomy of the normal maxillary sinus and to anticipate the selection of treatment plans. Methods CBCT data of 480 patients were selected and divided into 4 groups according to age: 18-24 years old group, 25-39 years old group, 40-54 years old group and ≥55 years old group. The CBCT data were imported into Mimics software to measure maxillary sinus volume(MSV), surface area, and the morphology of the maxillary sinus floor(MSF) bilaterally. The correlation with age and gender was analyzed using SPSS software. Results There was no significant difference in MSV and surface area between the left and right sides(P>0.05), and the MSV and surface area of males were higher than those of females(P<0.05). MSV was greater in the 18-24 and 25-39 age groups than in the other two groups, and the measurement of surface area was the greatest in the 18-24 age group(P<0.05). There was no significant correlation between gender and MSF morphology(P>0.05), but there was a significant correlation between age and MSF morphology(P<0.05). Conclusion The volume and surface area of the normal maxillary sinus are affected by age and gender and decrease with age, but the maxillary sinus morphology is symmetrical on the left and right side.
