翼腭窝是位于颞下窝内侧、眶尖后下方的狭小骨性间隙 ,窝内有重要的血管、神经结构通过 ,并与颅内外多个腔和窝相通。由于其位置特殊 ,解剖结构复杂 ,许多起源于鼻腔、眶、鼻旁窦及鼻咽顶部的病变可累及此窝 ,并可沿其通道向与之联系的腔和窝蔓延。随着以鼻内窥镜为代表的微侵 The pterygopalatine fossa is located in the medial infratemporal fossa, behind the orbital apex of the narrow bony gap, there are important blood vessels within the socket, the nerve structure through, and with multiple intracranial and extracavitary and litter communication. Due to its special location and complex anatomy, many lesions originating in the nasal cavity, orbital, paranasal sinuses and the top of the nasopharynx can affect this nest and spread along the path to the lumens and fossa associated with it.
