Blowout fracture

As the orbital floor (synonyms: blow- out fracture and overpressure fracture ) is called the ( by - ) fracture of the orbital floor to go maxillary sinus, usually caused by blunt contusion (eg by fist or tennis ball injury) and usually associated with the perception double vision and distinct disorders of eye movement. In particular, the passive range of motion is limited in this case, since muscle, connective tissue and retention are often trapped in the resulting fissure, or muscle hematomas are responsible for the movement disorders. Other symptoms may be an increase in intraocular pressure, looking in the direction of restraint, as well as sensory disturbances in the area of ​​the cheeks and upper lip, enophthalmos and Monokelhämatome.

Differential diagnosis, the mechanical limitations of neurogenic -related are to be defined. To distinguish actual ocular palsies of mechanically induced movement restrictions (pseudo paresis ) is the so-called traction test used (also: Pinzettenzugtest ), a method for testing the passive mobility of the eye.

Treatment

For pure pressure fractures surgical treatment is controversial with reconstructions of the orbit, as the benefits and success are controversial. Often spontaneous improvements are observed, which may arise after the accident, especially in the first four weeks. For this reason, treatment and possible surgical intervention previously closely with all participating physicians ( ear-nose- throat specialist, oral surgeon, ophthalmologist, radiologist ) should be discussed.
