Kaynak: MastoiditisThe structure of the squama is like that of the other cranial bones: the
mastoid portion is spongy, and the petrous portion dense and hard.

mastoid antrum (tympanic antrum, antrum mastoideum, Valsalva's antrum) is an air space in the petrous portion of the temporal bone ,

mastoid foramen is a large hole in the posterior border of the temporal bone . It transmits a
