Sphenoid bone may be affected by different variants of pneumatisation, which have a relevant importance from a clinical and surgical point of view. The description of such variants in different populations may give useful information. However, few articles describe the variability of sphenoid pneumatised structures and none of them focuses on Northern Italian population. Variants of pneumatisation of sphenoid bone were described in a sample of 300 Northern Italian patients who underwent a CT scan. More than fifty-seven percent of patients showed a form of anatomical variant: the most common form was the pneumatised pterygoid processes (39.6%), followed by dorsum sellae (32.9%) and clinoid processes (20.3%), without statistically significant differences between males and females (p > 0.01). In 26.3% of patients, a combined pneumatisation of these three structures was observed, being the combination pterygoid processes-dorsum sellae the most frequent (11.3%). In 9.3%, all the three sphenoid structures were affected. This article is the first description of the prevalence of different variants of pneumatisation in a Northern Italian population: the occurrence of such forms has to be acknowledged for their possible clinical and surgical consequences.
蝶骨可能会受到不同类型气化的影响，从临床和手术的角度来看，这些类型具有重要意义。在不同人群中描述这些变体可以提供有用的信息。然而，很少有文章描述蝶骨气化结构的可变性，也没有一篇文章专门针对意大利北部人群。在对 300 名接受 CT 扫描的意大利北部患者的样本中描述了蝶骨的气化变体。超过 57%的患者表现出一种解剖变体形式：最常见的形式是翼状突气化（39.6%），其次是鞍背（32.9%）和床突（20.3%），男女之间无统计学差异（p>0.01）。在 26.3%的患者中，观察到这三种结构的联合气化，其中翼状突-鞍背联合气化最为常见（11.3%）。在 9.3%的患者中，所有三种蝶骨结构都受到影响。本文首次描述了意大利北部人群中不同类型气化变体的流行情况：必须认识到这些形式的存在，因为它们可能具有临床和手术方面的后果。
