Currently, the traditional incision method has been improved and modified through the experience and thought of the surgeons. For surgeons with good surgical skills and a lot of surgical experience with children’s impingement generally tend to use the micropigmentation no-scar incision method to correct children’s impingement. Since the eye position of children under general anesthesia may be in a non-normal gaze position, some patients may have a flat eye position when the eyes are closed, some may have a very pronounced downward gaze, and some may have an upward gaze, and the non-normal gaze can make it difficult to determine the amount of debridement. This abnormal gaze can make it difficult to determine the amount of debridement of the lower eyelid and how to do it without over-debriding the lower eyelid and without being too conservative and causing the eyelashes to remain close to the cornea after surgery. The microscopic plastic incision method, as opposed to the traditional incision method only, does not absolutely cause lower eyelid scarring and lower eyelid double eyelids. Through microscopic techniques, microscopic sutures, fine manipulation and plastic surgery techniques, and microscopic suturing techniques, the scarring is greatly reduced or in some patients is barely noticeable, and the lower double eyelids do not appear or have a low chance of appearing or appear but appear so mildly that the appearance is not The lower eyelid is not visible, or the chance of it appearing is low, or it appears so little that the appearance is not affected. This method can avoid scarring and lower eyelids to a large extent, but why do some patients still have more or less faintly visible lower eyelids? Generally, the heavier the impingement, the more closely the eyelashes are attached to the cornea, the more the lower double eyelids will form during and after surgery because the strength and power to correct the impingement will be increased, and at the same time, the degree of double eyelids will be aggravated, while patients with a lighter degree of impingement will not be prone to scarring and lower double eyelids because the strength to correct the impingement is not as strong. Notes on post-operative care for ingrown eyelashes: 1. On the day of surgery and for two to three days after surgery, you can apply ice packs in order to reduce edema and bleeding, using plastic wrap or a plastic bag to ice the ice cubes in the refrigerator (also bags of drinks, bags of milk or yogurt) two to three times a day for 20 to 30 minutes each time. For one week after surgery, avoid spicy and stimulating food, beef, lamb, seafood and other hair products. Every two days after surgery, clean the lower eyelid wound with sterile saline soaked in sterile cotton swabs, wipe away the blood crust and secretions, then disinfect the wound with 75% alcohol and keep it clean and dry. 2. After 3 days of gauze coverage, if the environment is clean and hygienic and there are no environmental factors for infection (such as outdoor wind, dust, rain, etc.), gauze can be covered indoors without gauze. 3. 5 to 6 years old and above Children who understand and obey can be persuaded and induced with education. I usually give the removal of the sutures under the microscope in the operating room 7 to 10 days after the surgery. If the child cries or is timid and not strong enough, the stitches should not be removed so that the child does not move around and accidentally injure the eye. Therefore, the stitches should be removed only when the child is awake and cooperative, otherwise the stitches should be removed under anesthesia (e.g., general anesthesia or under sedative sleep medication). 4. It is a very fine cosmetic suture that can be absorbed by itself. It can be absorbed and the stitches can fall off within 1 to 3 months. Therefore, if you do not want to remove the stitches under general anesthesia, children who are awake under local anesthesia and cannot cooperate with the removal of the stitches can wait until the stitches absorb on their own. During this period, you can wash your face (after 10 days after surgery) and take a shower (you can wear swimming goggles to protect the sutures from dirty water), but do not swim. When swimming, the sutures get wet and dirty water can enter the subcutaneous tissue along with the sutures, causing redness and swelling. Therefore, if the sutures are not removed, the wound and sutures should be cleaned and disinfected regularly once a week, and the sutures should still be removed under general anesthesia if redness, swelling, granulomatous growth or infection is detected. During the 1 to 3 months of waiting for the sutures to absorb, make sure that the wound skin and sutures are clean and hygienic, and disinfect the wound and sutures with alcohol once or twice a week. 6. Usually 2 to 3 days after suture removal, the eye of the needle closes and the wound can be exposed to water when washing the face or bathing, so the wound is generally not affected and will not be infected. 7. In order to prevent the inner canthus (inner corner of the eye) from ectropion and affecting the appearance or the tear dots from being exposed, the inner canthus is usually peeled slightly conservatively, so some children may have a few lashes left in the inner canthus. This is because the inner canthus does not usually touch the cornea when looking straight ahead. Therefore, if parents find that there are still a few tiny eyelashes in the inner canthus against the white eyeball, there is no need to worry or panic.8. All cosmetic surgery wounds have a swelling period of one to three months, and the absorption period for subcutaneous bleeding and bruising is half a month to one month. It takes 1 to 3 months for the scar to fade, and 3 to 6 months for the longer ones, and in some patients, even the scar is not visible, which takes 6 months to 1 year. Most of the surgical patients can basically not see the surgical scar with the extension of time and recovery after surgery, except for the scar system. Since the surgery is still the surgical principle of double eyelids, a small number of children may still have more or less slight lower double eyelids. become larger. If you have one eye, you may have one big eye and one small eye after surgery. Generally, our eyes are not absolutely symmetrical in size, but this asymmetry is not easy to detect, so most of them will give us the impression that both eyes are symmetrical. If a patient has just one eye with an impingement and it so happens that this preoperative eye with impingement is larger than the non-impingement eye, then the postoperative eye with impingement surgery may become larger than the non-impingement eye, and this can exist.10. Removal of the suture is to lift the ends of the continuous suture of the lower eyelid and cut the knot at both ends, the middle is taken as a continuous suture with no knot, so it only needs to be You only need to cut it in sections, usually three to four, and then pull out the threads in sections.
