Abstract

OBJECTIVE

The aim of this study is to assess the distance between the anterior nasal spine and the sphenoidal rostrum related to the LeFort I surgery in a Turkish population sample.

MATERIAL AND METHODS

We retrospectively reviewed multidetector computerized tomography (MDCT) scans of 209 patients (134 males and 75 females). The images were obtained on a 64-MDCT scanner. The imaging parameters were 0.5 × 64 mm slice thickness, 0.5/0.3 mm increment, 120 kV, 250 mAs, 0.5 sn rotation time, 0.641 pitch, and 512 matrix. The distance between the anterior nasal spine and the sphenoidal rostrum was assessed with the Vitrea 2 software program.

RESULTS

The study group consisted of 134 male (mean age 57.90 ± 5.86) and 75 female (mean age 54.84 ± 4.31) patients. The distance between the anterior nasal spine and the sphenoidal rostrum was ranging between 40.4 and 70.9 mm (average 58.3 ± 5.9) in males and 45.0 and 63.2 mm in (average 55.2 ± 4.3) females. In addition, no statistically significant differences were found between genders.

CONCLUSION

The results of the current study showed that after 40 mm proceeding of the ball end nasal osteotome, the surgeons must be aware of penetrating the sphenoidal rostrum.

摘要

目的

本研究旨在评估土耳其人群样本中与LeFort I手术相关的前鼻棘与蝶骨 Rostrum 之间的距离。

材料与方法

我们回顾性分析了209例患者（134例男性和75例女性）的多排螺旋计算机断层扫描（MDCT）图像。图像在64排MDCT扫描仪上获取。成像参数为层厚0.5×64mm、层间距0.5/0.3mm、管电压120kV、管电流250mAs、旋转时间0.5秒、螺距0.641、矩阵512。使用Vitrea 2软件程序评估前鼻棘与蝶骨 Rostrum 之间的距离。

结果

研究组包括134例男性（平均年龄57.90±5.86岁）和75例女性（平均年龄54.84±4.31岁）患者。男性前鼻棘与蝶骨 Rostrum 之间的距离在40.4至70.9mm之间（平均58.3±5.9mm），女性在45.0至63.2mm之间（平均55.2±4.3mm）。此外，性别之间未发现统计学上的显著差异。
