Abstract

|
Blow out fractures occur in many patients who suffer from blunt trauma in the face. The typical signs and symptoms are diplopia, limited eye movement and enophthalmos. Upper eyelid ptosis is a relatively rare symptom caused by blowout fracture, where traumatic ptosis accounts for only 1-9%. The etiology is usually the result of a direct levator muscle injury due to eyelid trauma. Sometimes traumatic blepharoptosis occurs due to ischemic damage to the superior branch of the oculomotor nerve. Generally, blepharoptosis caused by blow out fracture is treated with conservative treatment unless there is some evidence of bone impingement. The authors report one case of blepharoptosis caused by blow out fracture, which was treated successfully.
