ABSTRACT:

Introduction: Anterior clinoidectomy is a surgical removal of the anterior clinoid process which is widely used to increase the clinoid space for the treatment of internal carotid artery or ophthalmic artery aneurysms, tumors of this region, and cavernous sinus pathology. Morphometric analysis of the anterior clinoid process would help the neurosurgeons while performing extradural or intradural anterior clinoidectomy.

Materials and Methods: The present study was consisting of 100 anterior clinoid processes in 50 adult human skulls of South Indian origin. The skull caps were removed and the skulls with damage or pathology near the sella turcica and anterior clinoid process were excluded from the study.  All the parameters were measured by using digital vernier calipers and the measurements were recorded.

Results and Discussion: The mean distance between the tips of the right and the left anterior clinoid processes, the medial margins of the right and the left optic canals, the lateral margins of the right and the left optic canals were 23.93 ± 1.69mm, 13.58 ± 2.15mm, and 19.75 ± 2.77mm respectively.  There was no significant difference between the right and the left sides with respect to the distance from the tip of  the anterior clinoid process to the medial margin of the optic canal, the distance from the tip of anterior clinoid process to the lateral margin of the optic canals, the distance from the medial margin of the optic canal to the lateral edge of the anterior clinoid process, the distance from the lateral margin of the optic canal to the lateral edge of the anterior clinoid process and the vertical dimension of the anterior clinoid process.

Conclusion: The knowledge on the morphometry of the anterior clinoid process gives guidance to the neurosurgeons while performing intra or extradural anterior clinoidectomy for various clinical conditions such as internal carotid artery or ophthalmic artery aneurysms, neoplasms of this region and also useful to the approach the optic nerve, cavernous sinus, clinoidal space and apex of orbit

Key words: Anterior clinoid process, Internal carotid artery, Aneurysms, Sphenoid, Anterior clinoidectomy.
