Abstract

Purpose: Detailed assessment of the extrasinusal pneumatization of the superior and middle turbinate (SCB, MCB), olfactory fossa (OFP), and nasal septum (NSP) in coronal and sagittal sphenoid sinus (SS) pneumatization types provides a precise understanding of the surgical corridors used for skull base surgery. We aimed to analyze the relationships among these variations using computed tomography (CT) images.

Methods: CT images of 153 patients were retrospectively analyzed for all types of sinonasal pneumatizations and volumes of SCB and sphenoid sinus, together with the prevalence of mucosal thickening of the sphenoid sinus (MTSS).

Results: The prevalences of cellular, extensive, and complete SCB were 28.6%, 21.1%, and 23.5% in prepterygoid; 38.1%, 42.1%, and 35.3% in prerotundum; and 33.3%, 36.8%, and 41.2% in postrotundum CSSP types, respectively. The frequencies of lamellar, bulbous, and extensive MCB were 29%, 14.3%, and 33.3% in pterygoid, 38.7%, 57.1%, and 25.9% in prerotundum, 32.3%, 8%, and 40.8% in postrotundum CSSP types, respectively. SCB and MCB were observed unilaterally at 24.8% and 30% and bilaterally at 12.8% and 32.7%, respectively. OFP, NSP, and MTSS were detected at 24.2%, 31.4%, and 27.5%, respectively. Increased age was significantly associated with a lower probability of pneumatization in SS and MCB.

Conclusions: The data obtained showed that the degree of SS pneumatization significantly affected the frequencies of the SCB, MCB, OFP, NSP, and MTSS. Also, the SCB volume is significantly related to the CSSP types. Preoperative CT evaluation is crucial for surgeons to be aware of these variations and to avoid iatrogenic injury.

不同蝶窦气化模式中、上鼻甲、嗅窝和鼻中隔的形态学变化。

目的：详细评估冠状和矢状蝶窦（SS）充气型中、上鼻甲（SCB， MCB）、嗅窝（OFP）和鼻中隔（NSP）的鼻外充气，为颅底手术的手术通道提供精确的理解。我们的目的是利用计算机断层扫描（CT）图像分析这些变化之间的关系。方法：回顾性分析153例患者的鼻窦气化、SCB、蝶窦体积及蝶窦黏膜增厚（MTSS）的CT表现。结果：细胞性、广泛性和完全性SCB的患病率分别为28.6%、21.1%和23.5%；占38.1%、42.1%、35.3%；轮后CSSP类型分别为33.3%、36.8%和41.2%。翼状椎板层型、球根型和广泛型MCB的发生率分别为29%、14.3%和33.3%，轮辐前型为38.7%、57.1%和25.9%，轮辐后型为32.3%、8%和40.8%。单侧SCB和MCB分别占24.8%和30%，双侧分别占12.8%和32.7%。OFP、NSP和MTSS的检出率分别为24.2%、31.4%和27.5%。年龄的增加与SS和MCB中较低的气化概率显著相关。结论：SS气化程度显著影响SCB、MCB、OFP、NSP和MTSS的发生频率。此外，SCB体积与CSSP类型显著相关。术前CT评估对于外科医生了解这些变异并避免医源性损伤至关重要。

期刊介绍： Neuroradiology aims to provide state-of-the-art medical and scientific information in the fields of Neuroradiology, Neurosciences, Neurology, Psychiatry, Neurosurgery, and related medical specialities. Neuroradiology as the official Journal of the European Society of Neuroradiology receives submissions from all parts of the world and publishes peer-reviewed original research, comprehensive reviews, educational papers, opinion papers, and short reports on exceptional clinical observations and new technical developments in the field of Neuroimaging and Neurointervention. The journal has subsections for Diagnostic and Interventional Neuroradiology, Advanced Neuroimaging, Paediatric Neuroradiology, Head-Neck-ENT Radiology, Spine Neuroradiology, and for submissions from Japan. Neuroradiology aims to provide new knowledge about and insights into the function and pathology of the human nervous system that may help to better diagnose and treat nervous system diseases. Neuroradiology is a member of the Committee on Publication Ethics (COPE) and follows the COPE core practices. Neuroradiology prefers articles that are free of bias, self-critical regarding limitations, transparent and clear in describing study participants, methods, and statistics, and short in presenting results. Before peer-review all submissions are automatically checked by iThenticate to assess for potential overlap in prior publication.
