The types and ratio of anterior clinoid process (ACP) pneumatization in paranasal sinus Multidetector Computerized Tomography (MDCT) were investigated the importance of ACP in neurosurgical approaches discussed.
Paranasal MDCT images of 499 subjects (259 male, 240 female), between 17 and 65 years of age, were included in the study. Presence and types of pneumatization of the ACP and pneumatization types (I, II or III) were evaluated.
ACP pneumatization was detected in 37.5% of the males and 33.3% of the females. Right, left and bilateral ACP pneumatizations were detected in 12.7%, 9.3% and 15.4% of males and 9.2%, 8.3% and 15.8% of the females, respectively. The most commonly detected types of pneumatization were Type I (49.1%) for right pneumatizations and Type II pneumatization for left (40.9%) and bilateral (37.2%) pneumatizations. In males, Type I (37.1%) and in females, Type II (40.0%) pneumatizations were detected more frequently. Type III pneumatization was detected in 29.9% of the males and 22.5% of the females. ACP pneumatization ratios were higher in younger subjects and lower in older subjects.
Sclerosis process related to aging may be responsible for the lower pneumatization ratios in older subjects. When Type III ACP pneumatization is present, clinoidectomy should not be performed: in this type of ACP pneumatization, cerebrospinal fluid fistula develops in all cases.
研究鼻窦多排螺旋计算机断层扫描（MDCT）中前床突（ACP）气化的类型及比例，并探讨ACP在神经外科手术入路中的重要性。
本研究纳入了499名年龄在17至65岁之间的受试者（男性259名，女性240名）的鼻窦MDCT图像。评估了ACP气化的存在情况、类型以及气化类型（I、II或III）。
男性中37.5%检测到ACP气化，女性中33.3%检测到。男性中右侧、左侧及双侧ACP气化分别在12.7%、9.3%和15.4%中检测到，女性中分别在9.2%、8.3%和15.8%中检测到。最常检测到的气化类型，右侧为I型（49.1%），左侧（40.9%）和双侧（37.2%）为II型。男性中I型（37.1%）和女性中II型（40.0%）气化检测更为频繁。男性中29.9%和女性中22.5%检测到III型气化。年轻受试者的ACP气化比例较高，老年受试者较低。
与衰老相关的硬化过程可能是老年受试者气化比例较低的原因。当存在III型ACP气化时，不应进行前床突切除术：在这种类型的ACP气化中，所有病例都会发生脑脊液漏。
