Ondokuzmayis University, School of Medicine, Department of Neurosurgery, Samsun, Turkey DOI : 10.5137/1019-5149.JTN.11295-14.2 AIM: The aim was to evaluate three-dimensional structure of the ophthalmic artery (OphA).

MATERIAL and METHODS: The raw data of the Three-dimensional Computerized Tomography Angiography (3D-CTA) were transferred to computer and recorded in a software program.

RESULTS: The study group consisted of 45 (24 female and 21 male) patients. The mean age of the patients was 569.5 years. It was found that the entry point of the OphA to the orbital cavity was inferior to the optic foramen in 29 (64.44%) of the cases. The length of the postcanalicular-prelacrimal was 0.540.13 centimeters at the right side and 0.510.13 centimeters at the left side. The distance of the postlacrimal-presupraorbital segment was 0.430.11 centimeters at the right and left sides. The location of the anastomosing site was 0.97 0.42 centimeters from the supraorbital notch.

CONCLUSION: The results of this study showed us that this technique could be used in the evaluation of the three-dimensional microsurgical anatomy of the OphA and its critical extracranial-intracranial anastomosing site.
