The pterygopalatine fossa (PPF) is a small anatomic region of particular interest in cranial base surgery. Infectious diseases and malignancy may spread through the PPF to contiguous areas as a result of the low resistance offered by the numerous foramina and fissures that surrounds the fossa. We present an anatomic report on the PPF. Twelve sides of six fixed cadaveric heads were dissected through a LeFort I maxillary osteotomy with transantral exposure of the neurovascular content of the PPF. Arterial vascular patterns of the maxillary artery were observed. The pterygopalatine fossa is a deeply located small anatomic region with a rich neurovascular content. The third portion of the maxillary artery in the PPF may demonstrate a variable vascular morphology. A correct understanding and knowledge of the anatomic structures lodged into the PPF, as well as their relationships and functions, remain crucial to minimizing postsurgical morbidity and intraoperative complications.
翼腭窝（PPF）是颅底手术中一个特别受关注的小解剖区域。由于围绕该窝的众多孔和裂隙提供的阻力较低，传染病和恶性肿瘤可能通过翼腭窝扩散到相邻区域。我们给出一份关于翼腭窝的解剖学报告。通过LeFort I型上颌骨截骨术并经窦暴露翼腭窝的神经血管内容物，对6个固定尸体头部的12侧进行了解剖。观察了上颌动脉的动脉血管模式。翼腭窝是一个位置较深的小解剖区域，神经血管丰富。翼腭窝内上颌动脉的第三部分可能呈现出可变的血管形态。正确理解和了解位于翼腭窝内的解剖结构及其关系和功能，对于将术后发病率和术中并发症降至最低仍然至关重要。
