Blow out fracture of orbit commonly involves:-
High-Yield Explanation
Blow out fracture of orbit Floor is involved first M.C fracture of orbit Force of blow cause a rise in intraorbital pressure with resultant fracture at the weakest point of orbital wall which is floor. THOUGH medial wall is thinnest but it is suppoed by ethmoid air cells which absorb pressure , thus it is not the most commonly fractured wall. Entrapment of inferior rectus in inferior wall fracture = not able to look up Features 1. Enophthalmous 2. Diplopia 3. Infra orbital nerve anesthesia
