Abstract

This study aimed to investigate the incidence of infraorbital canal (IOC) protrusion into the maxillary sinus via computed tomography (CT) and classify its variations. Additionally, it sought to identify nearby sinonasal variations that might elevate the risk of iatrogenic injury. Paranasal sinus CT of 500 patients was evaluated retrospectively. The IOC types were categorized. The length of the IOC, septum, the distance between the maxillary ostium and IOC (dOI), the presence of Haller cells, IOC-related intra-sinus opacity, and IOC dehiscence were investigated. The prevalence of type 3 IOC was 12%, of which 9.2% were type 3c. The maximum length of the IOC was positively correlated with type 3 IOC. A significant difference was found between IOC types in terms of dOI only on the left side. On both sides, the incidence of Haller cells was greater in patients with type 2 IOC than in those with type 1 and in patients with type 3 IOC than in those with type 2. IOC-related opacity and IOC dehiscence were more common in types 2 and 3 IOCs. The assessment of preoperative IOC types and neighboring anatomical structures by CT imaging is of great significance in preventing iatrogenic damage.

眶下管和邻近解剖结构的计算机断层扫描分析。

本研究旨在通过计算机断层扫描（CT）调查眶下管（IOC）突入上颌窦的发生率，并对其变异进行分类。此外，研究还试图找出可能会增加先天性损伤风险的附近鼻窦变异。对 500 名患者的副鼻窦 CT 进行了回顾性评估。对 IOC 类型进行了分类。对 IOC 的长度、鼻中隔、上颌骨骨膜与 IOC 之间的距离（dOI）、Haller 细胞的存在、与 IOC 相关的窦内混浊以及 IOC 开裂进行了调查。3型IOC的发病率为12%，其中9.2%为3c型。IOC 的最大长度与 3 型 IOC 呈正相关。不同类型的 IOC 仅在左侧的 dOI 上存在明显差异。在两侧，2 型 IOC 患者的霍勒细胞发生率高于 1 型患者，3 型 IOC 患者的霍勒细胞发生率高于 2 型患者。与 IOC 相关的不透明和 IOC 开裂在 2 型和 3 型 IOC 中更为常见。通过 CT 成像评估术前 IOC 类型和邻近的解剖结构对预防先天性损伤具有重要意义。

期刊介绍： Journal of Anatomy is an international peer-reviewed journal sponsored by the Anatomical Society. The journal publishes original papers, invited review articles and book reviews. Its main focus is to understand anatomy through an analysis of structure, function, development and evolution. Priority will be given to studies of that clearly articulate their relevance to the anatomical community. Focal areas include: experimental studies, contributions based on molecular and cell biology and on the application of modern imaging techniques and papers with novel methods or synthetic perspective on an anatomical system. Studies that are essentially descriptive anatomy are appropriate only if they communicate clearly a broader functional or evolutionary significance. You must clearly state the broader implications of your work in the abstract. We particularly welcome submissions in the following areas: Cell biology and tissue architecture Comparative functional morphology Developmental biology Evolutionary developmental biology Evolutionary morphology Functional human anatomy Integrative vertebrate paleontology Methodological innovations in anatomical research Musculoskeletal system Neuroanatomy and neurodegeneration Significant advances in anatomical education.
