[Post-traumatic ptosis].

Abstract

Traumatic ptosis is most often secondary to a fasciomuscular lesion of the levator system. Less frequently, it results from the paralysis of the levator muscle due to an injury to the third pair of cranial nerves. This ptosis is observed in comminuted orbital fractures or fractures of the base of the skull involving the orbital apex, and it is then associated with oculomotor paralysis. In favorable cases seen early, repairing surgery of the levator system produces excellent results. When associated with ophthalmoplegia or corneal anesthesia, neurogenic ptosis requires a watch and wait policy.
