Abstract：
OBJECTIVE: This study aimed to perform morphometric measurements of the pterygopalatine fossa (PPF), the transition zone to critical neurovascular structures. The second aim was to investigate the relationship between the volumes of the PPF and the paranasal sinuses and the effect of nasal septum deviation (NSD) types on all these measurements.
METHODS: We performed PPF\'s morphometry and all volume measurements on the CT images of 260 patients (130 male and 130 female, age range 18-79).
RESULTS: All volumetric measurements and the angle between foramen rotundum (FR) and pterygomaxillary fissure (PMF) were significantly higher in males than females. In contrast, the distance between sphenopalatine foramen (SPF) and PMF was considerably higher in females than in males. The PPF volume, the distance between the pterygoid canal (PC) and maxillary sinus, and the angle between FR and PMF were significantly higher on the right side than on the left. In contrast, the angle between PC and SPF and between greater palatine canal and PPF were considerably higher on the left side than on the right. The angle between PC and SPF decreased markedly with age. Only sphenoidal sinus volume was significantly smaller on the same side as the septal deviation. There was no correlation between PPF volume with maxillary and sphenoid sinus volumes from adjacent paranasal sinuses.
CONCLUSIONS: Volumetric and morphometric data obtained from PPF and paranasal sinuses can aid clinicians in diagnosing and treating patients by guiding them in selecting the right surgical approach or tools, especially in endoscopic procedures.

摘要：
目的：本研究旨在对翼腭窝（PPF）进行形态测量，关键神经血管结构的过渡区。第二个目的是研究PPF的体积与鼻旁窦之间的关系以及鼻中隔偏曲（NSD）类型对所有这些测量的影响。
方法：我们对260名患者（130名男性和130名女性，年龄范围18-79）。
结果：男性的所有体积测量值以及圆孔（FR）与翼颌裂（PMF）之间的角度均显着高于女性。相比之下,女性的蝶腭孔（SPF）与PMF之间的距离明显高于男性。PPF卷，翼状体管（PC）和上颌窦之间的距离，右侧FR和PMF之间的角度明显高于左侧。相比之下,左侧PC与SPF之间以及大腭管与PPF之间的角度明显高于右侧。PC和SPF之间的角度随着年龄的增长而明显减小。只有蝶窦体积在与间隔偏差相同的一侧明显较小。PPF体积与邻近鼻旁窦的上颌窦和蝶窦体积之间没有相关性。
结论：从PPF和鼻旁窦获得的体积和形态数据可以通过指导临床医生选择正确的手术方法或工具来帮助临床医生诊断和治疗患者。尤其是在内窥镜手术中。
