What is IAC (Internal Acoustic Canal)

In this Webpage you will learn about The aim of this paper was to present micro-computed tomography(micro-CT) high resolution images of the fundus of internal acoustic Canal (meatus) FIAM and characterize the normal appearance of its singular areas which are places of passage of numerous anatomical structures. By using micro-CT we obtain detailed volume rendering images presenting topography of the FIAM in 3-dimensional (3D) space. We figured out that 3D reconstructions obtained from micro-CT scans can precisely demonstrate all areas of the FIAM (facial nerve area, cochlear area, superior and inferior vestibular areas, singular foramen). Application of this technique allows finding out new anatomical structures like the foramen of the transverse crest, which is not described in literature.
