To investigate the morphometric characteristics of the lateral bone window (LBW) of the sella turica.
A descriptive anatomical study of LBW was performed in 530 cases of dry skull base specimens with relatively complete sella turcica. Detailed morphometric characteristics such as dimensions and classification of the LBW was studied. All data analysis was performed using SPSS 17.0 statistical software.
LBW is located in the lateral bony structures of sella turcica. The mean area sizes of the LBW were 75.99 ± 25.81 mm(2) (left) and 76.00 ± 25.53 mm(2) (right). There was no significant difference and there was a good positive correlation between bilateral areas of the LBWs. The area size of the LBWs is graded as follows: Grade A (< 60 mm(2)), B (60~90 mm(2)) and C (> 90 mm(2)). LBW morphology was typed as follows: Type I, II, III, IV. And Tpye III includes Type IIIa and IIIb; Type IV includes Type IVa, IVb, IVc, IVd.
The lateral bone window of sella turcica is an important structure located between pituiary fossa and parasellar region. The morphological measurements and variations of LBW in this study will provide preliminary data for further anatomical study of sella turcica. Moreover, knowing detailed anatomy of this region is essential for neurosurgeons who make surgery on cranial base or for teaching about the sella turcica in the neuroanatomy lab.
研究鞍旁侧骨窗（LBW）的形态学特征。
对 530 例干颅骨底标本进行了鞍旁侧骨窗的描述性解剖研究，这些标本的鞍区相对完整。研究了 LBW 的详细形态学特征，如尺寸和分类。所有数据分析均使用 SPSS 17.0 统计软件进行。
LBW 位于鞍区的侧骨结构中。LBW 的平均面积分别为左侧 75.99 ± 25.81mm²和右侧 76.00 ± 25.53mm²。左右侧面积之间无显著差异，且呈良好的正相关。LBW 的面积大小分为以下几类：A 级（<60mm²）、B 级（60~90mm²）和 C 级（>90mm²）。LBW 形态分为以下几类：I 型、II 型、III 型、IV 型。其中，III 型包括 IIIa 和 IIIb 型；IV 型包括 IVa、IVb、IVc、IVd 型。
鞍旁侧骨窗是位于垂体窝和鞍旁区之间的重要结构。本研究中 LBW 的形态学测量和变异将为进一步研究鞍区提供初步数据。此外，了解该区域的详细解剖结构对于在颅底进行手术的神经外科医生或在神经解剖实验室教授鞍区的教学都非常重要。
