This study aimed to investigate the effect of anatomical variations in the sphenopalatine foramen and the lateral nasal wall on sphenopalatine foramen-related morphometric measurements.
Paranasal sinus multidetector computed tomography records of 153 patients were evaluated. Morphometric measurements were made between the fixed bony landmarks and the sphenopalatine foramen. Number, shape, localization variations of the sphenopalatine foramen, concha bullosa, and septum deviation were noted and the results were compared with respect to sex, age, and laterality.
No significant difference was detected with respect to laterality, whereas most of the measured distances were higher in males than females. There was a significant difference between the obtained morphometric data according to age groups. In our study, 91.2% single, 7.8% double, and 1% triple sphenopalatine foramen were detected and the most common irregularly shaped (37.3%). The location of sphenopalatine foramen was reported as the most common type II. Septum deviation types have no potential influence on the location of the foramen, but most of the measured parameters were found to be significantly smaller in the presence of concha bullosa, whereas the angle was found to be higher.
This study revealed a significant relationship between the morphometric measurements of the sphenopalatine foramen and concha bullosa, while septum deviation types did not affect these results. For a safer and more effective surgery with prevention of iatrogenic complications, a surgeon should be aware of this correlation, especially in endoscopic transnasal approaches.
本研究旨在探讨蝶腭孔和外侧鼻壁的解剖变异对蝶腭孔相关形态测量的影响。
评估了 153 例患者的鼻窦多层 CT 记录。在固定的骨性标志和蝶腭孔之间进行形态测量。记录蝶腭孔、泡状鼻甲和鼻中隔偏曲的数量、形状、位置变化，并根据性别、年龄和侧别比较结果。
侧别无显著差异，而大多数测量距离男性高于女性。根据年龄组获得的形态测量数据存在显著差异。在我们的研究中，91.2%为单蝶腭孔，7.8%为双蝶腭孔，1%为三蝶腭孔，最常见的形状为不规则形（37.3%）。蝶腭孔的位置报告为最常见的 II 型。鼻中隔偏曲类型对孔的位置没有潜在影响，但大多数测量参数在存在泡状鼻甲时明显较小，而角度较高。
本研究表明蝶腭孔的形态测量与泡状鼻甲之间存在显著关系，而鼻中隔偏曲类型对这些结果没有影响。为了更安全、更有效地进行手术并预防医源性并发症，外科医生应该意识到这种相关性，特别是在经鼻内镜入路时。
