This study aimed to investigate the utility of three-dimensional reconstructions of paranasal sinus computed tomography data in depicting the anatomy of the frontal sinus drainage pathway.
Twenty-nine patients underwent imaging of the sinuses for various clinical indications. Variations in frontal sinus recess anatomy were determined from 0.75-mm thick coronal, axial and sagittal computed tomography images. Three-dimensional, reformatted images were generated from manually segmented volumes of interest. Observations were made on the variation and usefulness of these reconstructions.
Three-dimensional, reformatted images of segmented volumes aided delineation of the spatial relationships of the frontal sinus, frontal sinus drainage pathway, infundibular and meatal direction of drainage, agger nasi cells, ethmoid bulla cells, supraorbital cells, and suprabullar cells.
Three-dimensional, reformatted images of frontonasal anatomy enable improved understanding of the frontal sinus drainage pathway anatomy and of the spatial relationships between ethmoid air cells in this region. Such images may provide a useful adjunct to surgical planning and education.
本研究旨在探讨鼻窦计算机断层扫描数据的三维重建在描绘额窦引流途径解剖结构方面的效用。
29例患者因各种临床指征接受鼻窦成像检查。从0.75毫米厚的冠状位、轴位和矢状位计算机断层扫描图像确定额窦隐窝解剖结构的变异情况。从手动分割的感兴趣体积生成三维重组图像。对这些重建的变异情况及实用性进行观察。
分割体积的三维重组图像有助于描绘额窦、额窦引流途径、漏斗及鼻道引流方向、鼻丘气房、筛泡气房、眶上气房和筛泡上气房的空间关系。
额鼻解剖结构的三维重组图像能更好地理解额窦引流途径的解剖结构以及该区域筛窦气房之间的空间关系。此类图像可为手术规划和教学提供有用的辅助。
