Suboccipital Craniectomy — Occipital Craniotomy

  • Ludwig G. Kempe


The most frequent location for meningiomas of the posterior fossa, in our experience, is on the posterior surface of the petrous bone (see Fig. 60; compare Chapter XXI, Vol. I, p. 215). The major blood supply to these very vascular tumors arises from short branches of the internal carotid artery as it passes through the carotid canal within the petrous bone. Additional vessels from the posterior branches of the middle meningeal artery feed the tumor. In medially placed tumors near the clivus, the blood supply may be identical to that for a clivus meningioma, as described in Chapter XXII, Vol. I, p. 223 and Fig. 291. These tumors are attached to the dura over the posterior surface of the petrous bone anterior and superior to the internal auditory meatus and to the under-surface of the tentorium. The tentorium may be perforated by the tumor just as the falx is often penetrated by meningiomas in that location.
