A wide range of ocular trauma can occur concomitant with orbital fractures. Of patients who sustained a pure orbital floor fracture, intraocular injuries occurred

Various approaches to the orbital floor have been described, including a subciliary incision or through a laceration of the lower lid sustained during the injury; however, the degree of postoperative sequelae, including lower-eyelid retraction and lagophthalmos, has led to a shift to a tranconjunctival approach. Se hela listan på news-medical.net In adults, the orbital floor/medial wall bone is quite brittle and a hole of varying size may be created. However, in children the bone is more elastic. A trapdoor type of fracture may result, which is pushed down but springs back like a trapdoor, trapping the inferior rectus muscle, or at least some orbital fat, and preventing the eye from looking up. keywords = "Orbital floor fracture, entrapment, fracture, trauma", author = "Nora Silverman and Jordan Spindle and Tang, {Sunny X.} and Andrew Wu and Hong, {Bryan K.} and Shore, {John W.} and Sara Wester and Flora Levin and Michael Connor and Benjamin Burt and Tanuj Nakra and Todd Shepler and Eric Hink and Tarek El-Sawy and Roman Shinder", The orbital floor is most commonly affected, followed by the medial wall; the orbital roof is rarely fractured in isolation, and the lateral wall of the orbit is fractured with involvement of the orbital rim (see External orbital fractures, discussion of tripod fracture of the zygoma).

In children, nearly 50% of these injuries occur during sports, with the direct blow usually coming from a ball or another player (Hatton). Figure 2a,2b. An example of a patient presenting with a right orbital floor blowout fracture. Bruising and limited eye movements secondary to swelling are common clinical presentations (top). CT scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor (bottom).

RESULTS: Twenty-three patients met criteria for inclusion in this study (isolated orbital fracture thought to be in need of repair, with diplopia within 30° of primary gaze, and/or enophthalmos >2 mm, and/or 50% of the floor area involved in the fracture). The mean (SD) age of the patients was 31.5 (17.6) years (range, 8-73 years).

the floor is likely to collapse, because the bones of the roof and lateral walls are robust. Large fracture (> 50% of orbital floor on CT scan) indicates that enophthalmos is likely to occur. Concomitant medial orbital wall fracture can increase risk of progressive enophthalmos. Orbital floor fracture repair might be indicated in this setting for small or medium sized defects.

Blowout fractures of the orbit most frequently affect the middle third of the orbit where the orbital walls are the thinnest. 2019-01-23 Orbital floor fracture. Fig. 7. A patient with persist ent diplopia for 11 months following orbita l flo or reconstruc tion.

The weakest point on the orbital floor is usually along the infraorbital groove, therefore the greatest point of separation of the bone fragment in a blowout fracture is usually along the infraorbital groove. "Hinged" bone fragment can be separated at the infraorbital groove and attached to the medial wall (Figure 1). Fractures of the orbital floor and the medial orbital wall (blowout fractures) are common midface injuries. Orbital fractures have a distinct trauma mechanism and are complex, due to the complex anatomy of the bony and soft tissue structures involved.

The malar complex is also commonly fractured in isolation by a blow to that area. The bones are either fractured or dislocated.
