The most popular cosmetic procedure is double eyelid surgery, and for most of the candidates, the first choice for double eyelid is the less invasive buried double eyelid, but why would the hospital suggest you do a full cut double eyelid? Double eyelid surgery is the creation of an artificial connection between the skin and the levator muscle. Afterwards, if you open your eyes, as the levator muscle contracts and moves upward, it will pull the sutures together and the skin with the sutures will also follow upward, thus creating a fold on the surface of the eyelid and forming a double eyelid. Buried eyelid surgery is a procedure in which sutures or polymer sutures are placed directly between the skin and the lid plate, causing the upper eyelid skin to adhere to the lid plate and forming a heavy eyelid, based on the patient’s request for the curvature and width of the eyelid. Buried eyelid surgery is only suitable for young people with large lid fissures, thin eyelids, no bloating, no laxity in the eyelid skin and normal tension, and no medial canthus. Full eyelid surgery involves making an incision in the upper eyelid and removing excess skin and fatty tissue to fix the eyelid skin to the desired height of the lid to form a heavy eyelid. Full eyelid surgery is the most common, effective and reliable of all blepharoplasties. Full eyelid surgery is more suitable for people with thick or fatty lids, single eyelids where the two eyes are not the same size, or single eyelids with drooping lids. Each double eyelid needs to be tailored to suit the candidate’s own situation. No surgery is too big or too small, so the majority of candidates must be careful to choose a regular hospital when doing double eyelids.
