Blepharoplasty can be summarized into two categories: 1. Conjunctival approach blepharoplasty: It is suitable for young people who have primary blepharoplasty without lower eyelid skin and muscle laxity. The method is to turn over the lower eyelid, expose the lid, and make an 8-mm-long incision in the central part of the eyelid fissure at the lower edge of the lid, 3-4 mm, to reach the subconjunctiva and cut open the orbital septum to remove some of the orbital septal fat. The advantages of this surgical method are that the incision is hidden without scar, small trauma, less bleeding, no lid ectropion, separation of the lid bulb, tearing eyelid fissure closure incomplete. The disadvantage is that because there is no incision in the skin, the skin and orbicularis oculi muscle cannot be reshaped at the same time. At present, laser bag removal and some media publicized scarless bag removal surgery, in fact, is this method. 2. Skin approach blepharoplasty: An incision is made 1~1.5mm below the lower lid margin. Due to the lower eyelid skin, muscle, orbital septum, fat aging degree is different, and thus use different methods: (1) for the lower eyelid skin and orbicularis oculi muscle in the seated position when looking at the slightly loose, orbital lipids, but not beyond the orbital rim of the person, you can remove the orbital diaphragm fat at the same time to remove the excess skin and loose muscle, but do not have to the orbicularis oculi muscle flap to the outside of the above tight or fixed in the lateral orbital rim on the periosteum. (2) For those who have obvious laxity of skin and orbicularis muscle when sitting and looking at the plain view, but there is no accumulation of orbital fat and downward bulging of orbital fat, it is necessary to remove the skin and fat at the same time, and lift the orbicularis muscle flap outward and upward tightly and fix it in order to prevent the recurrence of the bag under the eyes. (3) Orbital fat release surgery is appropriate for those whose eyelid bags are dominated by skin and muscle laxity, and who have depressions in the infraorbital area and nasolabial folds.
