Blepharoplasty, commonly known as double eyelid surgery, is one of the most common cosmetic surgery procedures in ophthalmology. The surgical approach varies for different blepharoplasty cases. There are two general categories: the incision method and the buried liner method. Each category has a variety of procedures that add up to no less than 100, but the basic principles and methods are the same regardless of the procedure. The skin of the eyelid is connected to the levator aponeurosis so that the upper eyelid skin can be depressed to form the lid furrow when the eyes are open. Surgical methods 1. Incisional lid fixation: The incisional method is suitable for monolids with thick or fatty eyelids, monolids with two eyes of inconsistent size or droopy lids. It has the disadvantage of long surgery time and long recovery period compared to the buried lid method, but it is usually recoverable in 5-7 days. It regulates and changes the tissue structure of the upper eyelid at all levels and can address many of the complex problems that exist in the eyelid, such as lax upper eyelid skin, eyelash entropion, upper eyelid bloating, orbital fat sagging, septal laxity, and outer superior orbital rim bulging. The resulting heavy lid is firm and long-lasting, with deep creases and a three-dimensional appearance. The disadvantage is that the procedure is complex and requires familiarity with eyelid anatomy and a solid foundation in cosmetic eyelid surgery. After the surgery, the scars of the incision line are obvious for 3-6 months, but gradually fade as time passes, and edema is often noticeable one month after surgery, but by 2 months or more after surgery, it already looks natural. 2. The buried wire method is suitable for young people with large lid fissures, thin eyelids, no bloating, no laxity in the eyelid skin, normal tension, and no canthus. The advantages are that it is simple to perform and easy to master. The ligature is fixed between the upper lid dermis and the anterior or superior lid margin of the levator aponeurosis, resulting in a natural-looking crease. There is no incision and the post-operative tissue reaction is minimal and does not interfere with work, making it easy to accept. The disadvantage is that the upper lid crease can easily become shallow and narrow, and the duration of the procedure is short. Experts remind you that it is not suitable for people who want to have this surgery done conveniently and soon afterwards, the thread knots tend to loosen, leading to surgical failure, and there are many people who have to have a second surgery due to drooping eyelids. Post-operative treatment Self-care after eyelid surgery (also known as blepharoplasty) is the key to preventing post-operative wound infection and bleeding, and is an important part of the success of blepharoplasty. Reasonable and appropriate self-care after blepharoplasty can reduce post-operative complications and accelerate wound healing. Post-operative care can be done in the following ways: 1. Keep the wound clean to prevent infection. 2. Prevention and control of bleeding, bruising or hematoma in the surgical wound. 3, there should be a quiet and comfortable environment to recuperate after surgery. 4. There will be some pain in the wound on the day of surgery, but this will gradually decrease over time. 5. Patients who have had a blepharoplasty will have their stitches removed 5 to 7 days after surgery. Post-operative recovery Blepharoplasty usually recovers in about a week, while buried blepharoplasty may recover a little faster due to the small trauma. In addition, it has a lot to do with the candidate’s own care.
