This study aimed to measure the amount of maxillary sinus pneumatization (MSP) extended into alveolar processes in different age groups via cone-beam computed tomography (CBCT) and its association with age.
The data of 293 adult patients (533 maxillary sinuses) who underwent CBCT at our hospital from January 2020 to October 2020 were analyzed and divided into the following age groups: group I (18-34 years old, youth group), group II (35-59 years old, middle-aged group) and group III (≥ 60 years old, elderly group). The distance between the lowest point of the maxillary sinus floor and nasal cavity floor in the central area of the maxillary posterior teeth was measured and recorded as the amount of MSP. Further, according to the positional relation between the maxillary posterior teeth and maxillary sinus floor, MSP was divided into type I (normal pneumatization) and type II (extensive pneumatization). The distribution of pneumatization types and degree and change of pneumatization for the different age groups were also analyzed. P < 0.05 was used as the threshold for statistical significance.
The amount of MSP of group I [(3.75 ± 3.77) mm] was significantly higher than that of group II [(2.30 ± 4.48) mm] and group III [(2.09 ± 4.70) mm], but there was no significant difference between group II and group III. We also found that the amount decreased gradually with increasing age (r = - 0.2), with the youth group showing a higher prevalence of extensive pneumatization (youth vs. middle-age vs. elderly: 66.44% vs. 36.81% vs. 22.28%, respectively). There was no statistically significant difference in the amount of MSP between males and females and between left and right maxillary sinus in each group (P > 0.05).
The amount of MSP was significantly higher in the 18-34 years old group compared to older age groups, showed a decreasing trend with age and was not associated with sex and maxillary sinus sides.
本研究旨在通过锥形束 CT（CBCT）测量不同年龄组上颌窦气腔向牙槽突延伸的程度（MSP），并分析其与年龄的相关性。
分析 2020 年 1 月至 10 月在我院行 CBCT 的 293 例成年患者（533 侧上颌窦）的资料，按年龄分为 3 组：I 组（18-34 岁，青年组）、II 组（35-59 岁，中年组）和 III 组（≥60 岁，老年组）。测量上颌后牙区中央区上颌窦底至鼻腔底的最低点之间的距离，并记录为 MSP 量。根据上颌后牙与上颌窦底的位置关系，将 MSP 分为 I 型（正常气腔化）和 II 型（广泛气腔化）。分析不同年龄组的气腔化类型、程度分布及气腔化变化。P＜0.05 为差异有统计学意义。
I 组 MSP 量[（3.75±3.77）mm]明显高于 II 组[（2.30±4.48）mm]和 III 组[（2.09±4.70）mm]，但 II 组与 III 组间差异无统计学意义。我们还发现，MSP 量随年龄增长逐渐减少（r=-0.2），青年组广泛气腔化的发生率较高（青年组、中年组、老年组分别为 66.44%、36.81%、22.28%）。各组间男性与女性、左右上颌窦 MSP 量差异均无统计学意义（P＞0.05）。
18-34 岁组 MSP 量明显高于其他年龄组，呈随年龄增长而减少的趋势，与性别和上颌窦侧别无关。
