For blepharoplasty patients with true lower lid skin excess or redundancy, some skin must be removed to restore a youthful appearance. This is performed through a subciliary incision, which is an incision placed immediately below the lower lid lashes. This incision is hidden by the lower lid eyelashes and is almost always imperceptible once it has healed. As with upper lid, skin excision of the lower lid should be very conservative, amounting to only that amount of skin that is necessary to improve the lower lid skin contour. The muscle layer below must remain completely undisturbed, as it provides horizontal support for the lower lid and helps to maintain the lid position flush against the surface of the eye. Excessive removal of lower lid skin may lead to a complication called ectropion, where the lower lid is pulled down and away from the surface of the eye. This complication often requires additional surgery to correct it, and must therefore great care must be taken to avoid it. In eyelid surgery patients that do not have adequate lower lid tone or support, and in any patient felt to be at some risk of ectropion, a lateral canthopexy is performed to protect against that potential problem. The lateral canthus (the lateral corner of the eye) contains a tendon that attaches the lower lid tissues to the orbital rim laterally, and this tendon serves as a 'clothesline' that maintains lower lid position. A lateral canthopexy consists of an anchoring or supporting suture that tightens that tendon and thus the lower lid as well. When desired, a lateral canthopexy can also elevate the position of the lower lid. In patients who desire it, this procedure can produce a more 'almond' shape to the eyes.
