Posterior to Globe. SO runs in the superomedial aspect of the orbit. SR and LP can no longer be separated from one another. Note that both G and ON are seen in the same slice, demonstrating that ON does not arise from the most posterior aspect of the globe. This direct coronal view is the optimal view for assessing blowout fractures of the medial wall and floor of the orbit. Unlike the Waters view obtained with conventional x-rays, CT allows visualization of the fracture as well as the location of IR, not just soft tissue prolapse into MS. Fractures of MB are usually described based on the Le Fort classification. Le Fort I fractures do not involve the orbit. Le Fort II midfacial fractures cause floor fractures and are the most common of the Le Fort fractures, occurring in 35% to 55% of maxillary fractures. By definition, the type II fracture passes through NB, across the frontal process of MB and the lacrimal bones, and descends through the infraorbital rim and into the lateral inferior wall of MS. FB = Frontal Bone, G = Globe, IR = Inferior Rectus Muscle, LP = Levator Palpebrae Superioris, MB = Maxillary Bone, MS = Maxillary Sinus, NB = Nasal Bone, ON = Optic Nerve, SO = Superior Oblique Muscle, SOY = Superior Ophthalmic Vein, SR = Superior Rectus Muscle, TM = Temporalis Muscle, ZB = Zygomatic Bone.
