The volume of the air cavities in the paranasal sinuses is not only the simplest, but also the most important index for paranasal sinus evaluation. However, few volumetric studies have been performed in all age groups. The purpose of the current study was to outline the normal development of paranasal sinuses in all age groups, and to determine normal adult volumetric values by means of computed tomographic (CT) scan of paranasal sinus using volumetric procedures.
A prospective volumetric CT study was conducted with 260 patients (520 sides) <25 years of age by means of three-dimensional reconstruction.
The frontal sinuses began to pneumatize at 2 years of age, exhibited a faster growth pattern between 6 and 19 years of age, and the mean volume after full growth was 3.46±0.78 cm(3). The maxillary sinuses were pneumatized at birth in all cases, exhibited a monomodal growth pattern increasing until 15 years of age, and the mean volume after full growth was 14.83±1.36 cm(3). The floor of the sinus was the same level as the floor of the nasal cavity was between 7 and 15 years of age. The ethmoid sinuses exhibited a faster initial tendency to increase until 7 years of age, were completed by 15-16 years of age, and the mean volume after full growth was 4.51±0.92 cm(3). The sphenoid sinuses exhibited a growth spurt between 6 and 10 years of age, were completed by 15 years of age, and the mean volume after full growth was 3.47±0.93 cm(3).
The results of this study are presented to provide the basis for an objective normal volume of sinus development and for studies involving diseases of the sinuses.
鼻窦气腔容积不仅是评估鼻窦最简单的指标，也是最重要的指标。然而，针对所有年龄组进行的鼻窦容积研究较少。本研究的目的是概述所有年龄组鼻窦的正常发育情况，并通过鼻窦容积测量的计算机断层扫描（CT）来确定正常成人的容积值。
通过三维重建对260例25岁以下患者（520侧）进行前瞻性鼻窦容积CT研究。
额窦在2岁开始气化，在6至19岁之间呈现较快的生长模式，完全发育后的平均容积为3.46±0.78 cm³。所有病例中上颌窦在出生时即已气化，呈现单峰生长模式，至15岁时增大，完全发育后的平均容积为14.83±1.36 cm³。鼻窦底部在7至15岁时与鼻腔底部处于同一水平。筛窦在7岁前呈现较快的初始增长趋势，在15 - 16岁时发育完成，完全发育后的平均容积为4.51±0.92 cm³。蝶窦在6至10岁时出现生长高峰，在15岁时发育完成，完全发育后的平均容积为3.47±0.93 cm³。
本研究结果为鼻窦发育客观正常容积及鼻窦疾病研究提供了依据。
