Cons - scar, potential for ectropion, may weaken orbicularis musclePros - removes excessive skin, allows for lateral lift or canthopexyThis procedure, if done judiciously, will not result in major changes to your eye shape. But if done aggressively, will potentially change the shape/size of your eye. I now prefer the transconjuctival approach and pinch blepharoplasty where only the excess skin is removed on the outside.
The extended lower blepharoplasty is useful in patients that have a lot of redundant lower eyelid skin and fairly prominent periorbital wrinkles. A successful result depends on good incision placement, orbicular muscle suspension and a lateral canthopexy. Because it is a 'bigger' lower blepharoplasty the risks of lower eyelid retraction are greater and techniques must be done for its prevention.
