An understanding of the age-related changes in the volume of the normal maxillary sinus will help to identify sinus abnormalities. Normal maxillary sinus volume was measured on axial CT scans in 115 cases, and analysed in relation to age, the presence of premolar and molar teeth, size of the midfacial skeleton and body height and weight. The volume ranged from 4.56-35.21 cm3 (mean: 14.71 +/- s.d. 6.33 cm3) in patients aged over 20 years. There was no significant sex difference and a close correlation between the two sides was found. The volume increased up to the age of 20 years, but then decreased. There was no significant difference in patients with and without maxillary premolars and molars between the ages of 50 and 79 years. The difference in right and left dentitions had no influence on the maxillary sinus volume over the age of 20 years. Adult maxillary sinus volume correlated with the interzygomatic buttress distance. In adult females, there was a significant correlation between the volume and the zygomatic-occipital distance. In adult males, the volume correlated with body height and weight. It appears that volume changes with age might be related to skeletal size and physique.
了解正常上颌窦容积随年龄的变化有助于识别鼻窦异常情况。对115例患者的轴向CT扫描测量了正常上颌窦容积，并分析了其与年龄、前磨牙和磨牙的存在情况、面中部骨骼大小以及身高和体重的关系。20岁以上患者的容积范围为4.56 - 35.21立方厘米（平均：14.71±标准差6.33立方厘米）。未发现显著的性别差异，且两侧之间存在密切相关性。容积在20岁之前增加，但之后下降。50至79岁有和无上颌前磨牙及磨牙的患者之间无显著差异。20岁以上左右牙列差异对上颌窦容积无影响。成人上颌窦容积与颧弓支柱间距离相关。在成年女性中，容积与颧枕距离之间存在显著相关性。在成年男性中，容积与身高和体重相关。似乎容积随年龄的变化可能与骨骼大小和体格有关。
