Malar Fractures Associated With Exophthalmos

Blow-In Fracture of the Orbit

“…6 A third mechanism could be the impact of a force on the superolateral part of the zygoma. 7 In our first case, a sudden impact was given to the anterior maxillary wall and caused a depression fracture of the maxilla, yet the infraorbital rim remained intact. In our previous article, we reported a case with high pneumatic pressure of air injection, which induced a fracture of the medial wall.…”

Untreated ‘blow-in’ fracture of the orbital floor causing a mucocele: Report of an unusual late complication

“…Other authors have since described blow-in fractures a few times (Bernard et al, 1978;Lighterman and Reckson, 1979;Raflo, 1984;Godoy and Mathog, 1985;Antonyshyn et al, 1989;Chirico et al, 1989;Gruss and Hurwitz, 1990;Yoshioka et al, 1999). Orbital blow-in fractures are a distinct but relatively rare clinical entity.…”

“…Other authors have postulated that blow-in fractures are caused by buckling of the orbital floor secondary to severe compression of the orbital rim (Raflo, 1984). It has been proposed that a third mechanism could be the impact of a force on the laterosuperior part of the zygoma (Godoy and Mathog, 1985). In such a situation the malar complex has been said to rotate around an anteroposterior axis, causing the floor of the orbit to move inward and upward.…”

Orbital Fractures - An Overview

“…16 Since then isolated cases of blow-in fractures have been documented involving the floor, lateral rim, zygoma and roof of the orbit. [17][18][19][20] A typical fracture causing orbital contraction is an orbital roof fracture in which the displacement of the roof downwards and backwards results in downward and forward displacement of the globe.…”
