What operative techniques do you use to minimize the risk of postoperative ectropion in a patient with pre-existing lower eyelid laxity undergoing lower eyelid blepharoplasty?  

I favor a transconjunctival approach for the fat excision or transposition, combined with either pinch skin excision or CO2 laser resurfacing, and horizontal tightening either by canthopexy (in milder laxity patients) or a full tarsal strip procedure in severe laxity or frankly ectropic patients.
