In the human eyelid skin deep there was a small, thin muscle, medicine called levator muscles. It shrinks the upper eyelid raised, eyes will open. It is part of the muscle fibers beyond the upper eyelid skin, eyes open, because this part of the muscle fiber tension, so that the skin on the eyelid of a wrinkle, which is double fold out. Some yellow to the skin of upper eyelid skin is no such muscle fibers, which some people is the single fold.
For single fold into a double-fold, many ways. The formation of double-fold with the surgical method known as double eyelid surgery. Double eyelid is divided into two incision and suture method, and their basic principles are the same, namely, the skin and tarsal plate in the upper eyelid levator muscle aponeurosis or between the traumatic, scar adhesions, if the scar adhesion is not strong, double eyelids will disappear.
Not all people are suitable for single fold double-fold eyelids, and not all have double eyelids were cut, the surgery will be satisfied. The constraints include:
(1) the design of the incision. It is related directly and results of operations. Incision design and location of the patient's aesthetic requirements and is closely related to physicians, so patients before surgery with the plastic surgeon should be a serious discussion, so that after the operation due to a different understanding of the effects arising from differences.
(2) the patient's own conditions. Some patients want to do double eyelid, but their condition is not good enough, the effect is also poor. For example: eye protrusion in patients with more to do double eyelid surgery, may change in appearance, seems in a daze, face more serious. Such factors include: the smaller the eye, the distance between the eyes closer to those eyebrows and too much fat on the eyelid, as well as in patients with upper eyelid skin is very loose. Before surgery should consider these factors carefully.
(3) the physical scars of the patients, not to do this surgery, or postoperative scar caused, damage cosmetic results.
(4) If the infection of the face, such as folliculitis, acne, etc., after cure of these diseases should be considered a facial surgery.
(5) should be treated eyes and conjunctivitis eye diseases, healed before making a double eyelid surgery.
(6) Women do not operate best during menstruation, due to more blood loss, postoperative swelling for a long time and reaction weight, of results of operations, it is best to clean after the surgery is scheduled three or four days in the period further.
Finally, there is an important factor is the quality of the plastic surgeon. A good plastic surgeon for surgery should have a deep understanding of thoroughbred training, good surgical skills and dedication of medical ethics for the sake of patients, otherwise, the small operation may also cause harm to patients.
