RT Journal Article SR Electronic T1 Orbital Roof Blow-out Fractures JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 531 OP 534 VO 3 IS 5 A1 Hugh D. Curtin A1 Patrick Wolfe A1 Victor Schramm YR 1982 UL http://www.ajnr.org/content/3/5/531.abstract AB Blow-out fractures usually involve the floor or medial wall of the orbit. However, if the roof of the orbit is thin, a blow-out fracture can occur upward into the frontal sinus. Two cases of orbital roof blow-out fractures are presented including plain films and tomographic findings. Neither fracture required surgical correction.
