翼腭窝
在人类解剖学中,翼腭窝(pterygopalatine fossa,或sphenopalatine fossa)为人类颅骨中一个窝状构造。翼腭窝共有一对,为颞下窝内侧的一个圆锥状凹窝。该窝位于上颌骨后方[1]。翼腭窝位于翼上颌裂内侧,通往蝶腭孔,可通向鼻腔、口腔、颞下窝、眼眶,及咽,另有8个孔通向中颅窝[2]。

翼腭窝向外通颞下窝,向前藉眶下裂通眶,向内藉腭骨与蝶骨围成的蝶腭孔通鼻腔,向后藉圆孔通颅中窝,藉翼管通颅底外面,向下移行至腭大管,继而经腭大孔通口腔。
解剖
边界
下列为翼腭窝的边界:
- 前界:颞下窝内上部分。
- 后界:翼突根部,必毗邻蝶骨大翼前缘。
- 内界:腭骨垂直板及蝶骨突
- 外界:翼上颌裂
- 下界:part of the floor is formed by the pyramidal process of the palatine bone.

功能
翼腭窝内包含
- the pterygopalatine ganglion suspended by nerve roots from the maxillary nerve
- the terminal third of the maxillary artery
- the maxillary nerve (CN V2, the second division of the trigeminal nerve), with which is the nerve of the pterygoid canal, a combination of the greater petrosal nerve (preganglionic parasympathetic) and the deep petrosal nerve (postganglionic sympathetic). To obtain block anesthesia of the entire second division of the trigeminal nerve, an intraoral injection can be administered into this area.
