Abstract

AIM

To compare the morphometric characteristics of the foramen ovale (FO) and foramen rotundum (FR), and their localization in the middle cranial fossa on the head and neck computed tomography images of patients with trigeminal neuralgia (TN) and asymptomatic individuals.

MATERIAL AND METHODS

The FO and FR length, width, and area parameters were examined in 158 asymptomatic individuals and 19 patients with TN. Their localization in the middle cranial fossa was determined according to the sagittal (y) axis passing through the middle of the dorsum sella and connecting the foremost point and the rearmost point of the skull and the transverse (x) axis passing through the middle of this axis. In the comparison with asymptomatic individuals, data on the painful side of patients with trigeminal neuralgia were used.

RESULTS

The mean width of the FO and its distance from the transverse axis were determined to be 3.36 ± 0.79 mm and 1.44 ± 0.39 mm in asymptomatic individuals and 2.88 ± 0.83 mm and 1.23 ± 0.45 in TN patients, respectively. These FO parameters were statistically significantly smaller in patients with TN. In asymptomatic individuals, while the mean width of the FR was determined to be 2.05 ± 0.48 mm, the mean length was 2.14 ± 0.47 mm, and its distances to the transverse axis and sagittal axis were found to be 2.65 ± 0.35 mm and 1.96 ± 0.25 mm, respectively. In patients with TN, while the mean width of the FR was revealed to be 1.77 ± 0.46 mm, the mean length was 1.78 ± 0.42 mm, and its distances to the transverse axis and sagittal axis were found to be 2.33 ± 0.40 mm and 1.87 ± 0.16 mm, respectively. These FR parameters were statistically significantly smaller in patients with TN.

CONCLUSION

Statistically significantly smaller dimensions of the FO and FR and their distances to the sagittal and transverse axes in patients with TN suggested that they might be among the causes of TN.

摘要

目的

比较三叉神经痛（TN）患者和无症状个体头颅和颈部 CT 图像中卵圆孔（FO）和圆孔（FR）的形态特征及其在中颅窝的定位。

材料与方法

在 158 名无症状个体和 19 名 TN 患者中检查了 FO 和 FR 的长度、宽度和面积参数。根据矢状（y）轴穿过鞍背中部并连接颅骨最前点和最后点，以及穿过该轴中部的横（x）轴确定其在中颅窝的定位。在与无症状个体的比较中，使用了 TN 患者患侧的数据。

结果

在无症状个体中，FO 的平均宽度及其与横轴的距离分别为 3.36 ± 0.79mm 和 1.44 ± 0.39mm，而在 TN 患者中分别为 2.88 ± 0.83mm 和 1.23 ± 0.45mm。这些 FO 参数在 TN 患者中统计学上显著较小。在无症状个体中，FR 的平均宽度为 2.05 ± 0.48mm，平均长度为 2.14 ± 0.47mm，其到横轴和矢状轴的距离分别为 2.65 ± 0.35mm 和 1.96 ± 0.25mm。在 TN 患者中，FR 的平均宽度为 1.77 ± 0.46mm，平均长度为 1.78 ± 0.42mm，其到横轴和矢状轴的距离分别为 2.33 ± 0.40mm 和 1.87 ± 0.16mm。这些 FR 参数在 TN 患者中统计学上显著较小。
