<prompt> Blow out fracture of orbit most commonly leads to fracture ofLateral wallRoof of orbitMedial wall of orbitPosterior-medial wall of floor  <response>: This fracture usually occurs where the bone is thinnest, along with the paper-thin floor of the orbit over the maxillary sinus. The ring-shaped bony orbital rim usually remains intact. The fracture can result in protrusion and impingement of orbital fat and the inferior rectus and its sheaths in the fracture gap.
