Levator injury during blepharoplasty.

Upper eyelid blepharoplasty has been increasing in popularity and complexity. New techniques involve deep dissection into the upper eyelid, with increased surgical risk to the levator complex. The resulting forms of trauma and subsequent ptosis commonly include direct injury, edema, hematoma, supratarsal fixation, and septal adhesion. Ptosis after blepharoplasty is common and, while spontaneous resolution occurs in some cases, other may require one of the suggested methods for treatment.
