Double eyelid operations.

The double eyelid in the Chinese population is a desirable physical feature, which is now increasingly popular and demands modern up-to-date aesthetic operations for its formation. The author describes 3 types of double eyelid operations, e.g., the ligation method, the incision method, and the skin grafting method. The advantages, disadvantages, and indications for each of these methods are evaluated and discussed. The creation of a double eyelid from an anatomic point of view is especially emphasized, with the illustrations of the anatomy and the operation made by the senior author.
