[Fractures of the orbit floor].

Fractures of the floor are not common during childhood, their main cause being trauma. The mechanism is an increased pressure in the orbital cavity, which breaks at is weakest point, the floor, where soft tissue may be trapped- periorbitary fat, inferior rectus muscle, and inferior oblique muscle. Symptoms are diplopia, enoftalmos, eyelid ptosis and soft tissue haematoma. The diagnosis is made on the clinical and imaging findings, CT-Scan being the most reliable technique. Surgical treatment is necessary when symptoms do not subside and when the muscles or the infraorbitary nerve are compromised. We present four cases of orbit floor fracture which were completely resolved with conservative management (2 cases) or with surgical release of the muscular structures and orbit floor reconstruction (2 cases).
