WitrynaThe Hertel scale improved from -1.04 mm before the surgery to -0.78 mm after the surgery, but no significant difference was observed (P = 0.051).The OVR was useful as a quantitative value to evaluate pure blow-out fractures, compared with that of the Hertel scale. Fracture location-associated OVR studies are needed to make volume … WitrynaFrontal blow to orbit causes increased intraorbital tension causing fracture of floor of the orbit (weak point) with prolapse of orbital content into the maxillary sinus cavity. This causes enophthalmos and diplopia. Infraorbital rim is not involved in pure blow out fracture, it is also involved then it should be considered as an impure blow out
Oogkasfractuur (gebroken oogkas): Soorten en symptomen
An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall that typically results from the impact of a blunt object larger than the orbital aperture, or eye socket. Most commonly this results in a herniation of orbital contents through the orbital fractures. The proximity of maxillary and ethmoidal sinus increases the susceptibility of the floor and medial wall for the orbital blo… Witryna1 kwi 2007 · Les fractures « blow-out » pures du plancher de l’orbite représentent une forme particulière des fractures de l’orbite.

Change of the orbital volume ratio in pure blow-out fractures
Witrynablow-out fracture in 60 of 62 patients and bilateral blow-out fractures in two patients (Fig. 1). Of the 64 orbital fractures, 26 were pure, and 38 were impure blow-out fractures. A pre-operative ophthalmology consultation was obtained for all cases. An ophthalmologist using a Hertel exophthal-mometry assessed the existence of … Witryna8 lut 2024 · In the report, in which just over 50% of 447 patients with pure blow-out fractures presented with evidence of diplopia, statistically significant associations were found between orbital floor fractures and diplopia on eye elevation, and between medial wall fractures and horizontal diplopia. The investigators suggested, therefore, that the … WitrynaA blow-out fracture is a fracture of one of the walls or floor of orbit with an intact orbital rim. It is the commonest orbital fracture, with orbital floor fractures more common than medial wall fractures. It is produced by a blow to the orbit which suddenly increases the intraorbital pressure, fracturing a portion of the orbital bony lining. ons vs onc certification
