Ans. is 'a' i.e., Floor 1129] Blow out fractures of orbit Blow out fractures are caused by direct trauma to the globe which causes an increase in infraorbital pressure and decompression fracture of the orbital floor (or its walls). They are usually due to blunt trauma caused by a large object such as a cricket ball, human fist etc. o Most commonly the orbital floor blows, but it can also affect the medial wall of the orbit. The most common site for a blowout fracture to occur is the posteromedial aspect of the orbital floor, medial to the infraorbital neurovascular bundle where the maxillary bone is very thin. Lamina papyracea is also thin and the medial orbital wall is also prone to fracture. Although the lamina papyracea is thinner than the maxilla, the existence of ethmoid air cells reinforce the medial wall like corrugated paper or a beehive. The orbital floor overlies the maxillary sinus without reinforcement, therefore is weaker and more blowouts tend to occur here especially in the posteromedial floor (near the infraorbital groove), where it is the weakest area. Fracture of the floor causes the orbital contents to collapse into the maxillary sinus, causing enophthalmos and entrapment of the inferior rectus muscle. Blowout fractures are divided into pure and impure. The term pure orbital blowout fracture is used to describe a fracture of the orbital floor, the medial orbital floor or both, with an intact bony orbital margin. The term impure orbital blowout fracture is used when such fractures occur in combination with a fracture of the orbital rim.
