Brief Clinical Studies

Abstract: We report 2 patients with blow-in fractures of the orbital floor caused by different mechanisms. In a 17-year-old boy, a sudden impact was given to the anterior maxillary wall and caused a depression fracture of a maxilla, yet the infraorbital rim remained intact. We think fragments of the orbital floor were forced into the orbit by a sudden increase in pressure in the maxillary sinus in this patient. In a 51-year-old man, the impact of a force was on the laterosuperior part of the zygoma, which pushed the zygoma medially. These 2 cases represent 2 different mechanisms of blow-in fractures of the orbital floor.
