Abstract
The anterior clinoid process is a part of the sphenoid bone overlying the optic nerve and the carotid artery taking a veer medially to the planum sphenoidale, anterolateraly to the sphenoid ridge and caudally to the optic strut. Partial removal of the process has been recommended for the surgical management of aneurysms of the internal carotid artery (ICA) at its proximal intradural part, already as early as in 1972 [11, 12, 19]. It was however only in 1993 that the method of systematic en bloc removal of the bone fragment including the whole anterior clinoid process (ACP), namely, selective extradural anterior clinoidectomy (SEAC) was carried out, which then was reported in 1997 [22]. With this method one may obviate the more invasive and time consuming technique of extensive orbital roof removal together with anterior clinoidectomy which had been applied in surgical treatment for parasellar and cavernous pathologies pioneered by Dolenc [2, 3]. In this chapter, advantages, indications, technical details and complications are clarified.
