在人類解剖學中,翼齶窩(pterygopalatine fossa,或sphenopalatine fossa)為人類顱骨中一個窩狀構造。翼齶窩共有一對,為顳下窩內側的一個圓錐狀凹窩。該窩位於上頜骨後方[1]。翼齶窩位於翼上頜裂內側,通往蝶齶孔,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]。
翼齶窩向外通顳下窩,向前藉眶下裂通眶,向內藉齶骨與蝶骨圍成的蝶齶孔通鼻腔,向後藉圓孔通顱中窩,藉翼管通顱底外面,向下移行至齶大管,繼而經齶大孔通口腔。

解剖
下列為翼齶窩的邊界:
- 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:齶骨垂直板及蝶骨突
- 外界:翼上頜裂
- 下界:part of the floor is formed by the pyramidal process of the palatine bone.

功能
翼齶窩內包含
- 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.
