Numbness after blepharoplasty was infrequent complication (less than 1 percent). It represents nerve injury to terminal branches of the ophthalmic division division of the trigeminal nerve which are found superior and superomedial to fat in the upper orbital fat compartments. Nerve injury has multiple mechanisms and can be avoided by recognition of the proximity of sensory nerve fibers to orbital fat and by awareness of the mechanism of injury.
