Anatomical variations of the intracavernous branches of the internal carotid artery with reference to the relationship of the internal carotid artery and sixth cranial nerve. A microsurgical study.

Thirty cavernous sinuses were dissected and examined using microsurgical methods under a magnification of X10 and X16. The anatomical variations of the intracavernous branches of the internal carotid artery (ICA) and the anatomical relationship of the sixth nerve with the ICA are described and discussed in relation to the findings from other microsurgical works.
