在人類解剖學中,翼腭窝(pterygopalatine fossa,或sphenopalatine fossa)為人類顱骨中一個窩狀構造。翼腭窝共有一對,為颞下窝内侧的一個圓錐狀凹窩。該窩位於上颌骨後方[1]。翼腭窩位於翼上頜裂內側,通往蝶腭孔,可通向鼻腔、口腔、顳下窩、眼眶,及咽,另有8個孔通向中顱窩[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
下列為翼腭窝的邊界:
- 前界:顳下窩內上部分。
- 後界:翼突根部,必毗鄰蝶骨大翼前緣。
- 內界:腭骨垂直板及蝶骨突
- 外界:翼上頜裂
- 下界:part of the floor is formed by the pyramidal process of the palatine bone.

功能
翼腭窝內包含
- 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.
