In : In experienced hands it would be exceedingly rare for this type of injury to occur. Another consideration is to avoid the problem of not being to fully close the eye. An experienced surgeon should be able to prevent this type of permanent complication as well.

This : This a legitimate patient concern but is an exceedingly rare occurrence usually due to a detachment of the levator aponeurosis and not an injury to a nerve. Occasionally a traumatic injury occurs to the facial nerve that creates a situation where the upper eyelid cannot close. The nerve that controls this action is outside the area that is operated on during a blepharoplasty and is most commonly caused by a blow to the side of the head.

Blepharoplasty: Nerve damage is not a usual complication of blepharoplasty.
