The objective of this study is to clearly and precisely describe the topography and contents of the infratemporal fossa. Ten formalin-fixed, adult cadaveric specimens were studied. Twenty infratemporal fossa were dissected and examined using micro-operative techniques with magnifications of 3-40×. Information was obtained about the inter-relationships of the contents of the infratemporal fossa. The infratemporal fossa lies at the boundary of the head and neck, and the intracranial cavity. It is surrounded by the maxillary sinus anteriorly, the mandible laterally, the pterygoid process anteromedially, and the parapharyngeal space posteromedially. It contains the maxillary artery and its branches, the pterygoid muscles, the mandibular nerve, and the pterygoid venous plexus. The course and the anatomic variation of the maxillary artery and the branches of the mandibular nerve were demonstrated. The three-dimensional (3D) relationships between the important bony landmarks and the neurovascular bundles of the infratemporal fossa were also shown. The skull base anatomy of the infratemporal fossa is complex, requiring neurosurgeons and head and neck surgeons to have a precise knowledge of 3D details of the topography and contents of the region. A detailed 3D anatomic knowledge is mandatory to manage benign or malignant lesions involving the infratemporal fossa without significant postoperative complications.
本研究旨在清晰、准确地描述颞下窝的解剖结构和内容物。使用 3-40 倍的显微手术技术对 10 例福尔马林固定的成人尸体标本进行研究。共解剖和检查了 20 个颞下窝，以获取关于颞下窝内容物相互关系的信息。颞下窝位于头颈部和颅腔的交界处，其前界为上颌窦，外侧为下颌骨，前内侧为翼状突，后内侧为咽旁间隙。它包含上颌动脉及其分支、翼内肌、下颌神经和翼状静脉丛。本文展示了上颌动脉及其分支的走行和解剖变异，以及颞下窝重要骨性标志与神经血管束之间的三维（3D）关系。颞下窝颅底解剖结构复杂，要求神经外科医生和头颈部外科医生对该区域的解剖结构和内容物的 3D 细节有精确的了解。详细的 3D 解剖学知识对于管理涉及颞下窝的良性或恶性病变，避免出现严重的术后并发症是必需的。
