The aim of this study is to investigate the volumetric measurements of the maxillary sinus among Indonesian population through computed tomography (CT) scan semi-automated segmentation. This project collected 802 retrospective head CT scan archives from Department of Radiology, Hasan Sadikin Hospital, Bandung, Indonesia between 2019-2020. Patients with craniofacial anomalies/pathology fracture in proximity of the maxillary sinuses, and mediocre image quality were excluded from this study resulting only 97 CT scan archives (194 maxillary sinuses; 52 males; 45 females; age range 0-25 years old). Three-dimensional craniofacial structures were reconstructed and volumetric measurements of the maxillary sinus were computed through semi-automated segmentation using ITK-SNAP. This study recorded the initial phase of maxillary sinus pneumatization during infancy. The maxillary sinus developed until reaching the maximum of average maxillary sinus volume at 13,278.73 mm in 16 to 20 years old group in which afterwards fell to 12,325.21 mm. There was no difference found between right and left maxillary sinus volume. This study revealed that the pneumatization of maxillary sinus begin during infancy and climb until reaching the second decade of life, in which after that slowly decrease. Moreover, no difference between right and left maxillary sinus volume was detected. The volumetric dimension of maxillary sinus presented in this study may serve as the basis knowledge surgical intervention of maxillary sinus and its related structures.
本研究的目的是通过计算机断层扫描（CT）扫描半自动分割技术，调查印度尼西亚人群上颌窦的容积测量情况。该项目收集了2019年至2020年间印度尼西亚万隆哈桑·萨迪金医院放射科的802份回顾性头部CT扫描档案。上颌窦附近有颅面异常/病理性骨折以及图像质量一般的患者被排除在本研究之外，最终仅得到97份CT扫描档案（194个上颌窦；52名男性；45名女性；年龄范围0至25岁）。通过使用ITK-SNAP进行半自动分割，重建了三维颅面结构并计算了上颌窦的容积测量值。本研究记录了婴儿期上颌窦气化的初始阶段。上颌窦不断发育，在16至20岁组达到平均上颌窦容积最大值132,78.73立方毫米，之后降至123,25.21立方毫米。左右上颌窦容积之间未发现差异。本研究表明，上颌窦气化始于婴儿期并持续上升，直至生命的第二个十年，之后逐渐下降。此外，未检测到左右上颌窦容积之间存在差异。本研究中呈现的上颌窦容积尺寸可为上颌窦及其相关结构的手术干预提供基础知识。
