Suggestion: There are also two ways to improve the frontalis muscle: one is to connect the tarsus and frontalis muscle with some materials or tissues, and indirectly use the strength of frontalis muscle to correct ptosis. At present, the materials and tissues used are autologous fascia lata, skin, muscle, allogenic dura mater, allogenic sclera, silk thread, silver thread, stainless steel thread and silicone rubber strip. Among them, autologous fascia lata has a good effect, and it will not be rejected and prolonged after implantation, and the height of eyelid fissure and eyelid shape are stable after operation. The disadvantage is that patients need to make more openings in their thighs, which is not easy to be accepted by patients, and the operator also feels troublesome. Moreover, patients also need to use frontal muscle contraction to lift eyebrows to split eyelids, so patients have different degrees of eyebrow lifting after surgery. Using allogenic dura mater or allogenic sclera to lift the eyelid, but after several years, the upper eyelid drooped slowly, or some eyelids were deformed, and a few of them lost their curative effect because of early absorption or fibrosis of implanted tissue. Silk thread has good short-term correction effect and convenient operation, but its maintenance time is much shorter than that of allogenic dura mater or sclera, so it is basically not used at present. Treatment of ptosis. Shortening levator palpebrae superioris muscle has been improved by countless operators. At present, there are many changes in the surgical methods of ptosis, which can be roughly divided into transconjunctival incision (internal incision method) and percutaneous incision (external incision method) or conjunctival skin combined incision. It is suitable for bilateral or unilateral mild and moderate congenital ptosis, and the levator palpebrae superioris muscle still has some functions (the muscle strength of levator palpebrae superioris muscle is more than 5mm). It can also be used for aponeurosis ptosis caused by acquired. This kind of operation keeps the original walking and moving direction of muscles, which is more in line with the physiological requirements of the eyes and the postoperative effect is ideal. However, this method is limited to mild and moderate ptosis with partial function of levator palpebrae superioris, such as poor function of levator palpebrae superioris (muscle strength of levator palpebrae superioris is less than 5mm). Shortening levator palpebrae superioris muscle or adding muscle to move forward may not achieve satisfactory surgical results. If the muscle function is completely lost, it will be more difficult to achieve the effect, and a large number of muscle shortening operations will be forced, resulting in serious complications such as eyelid dysfunction and diplopia after operation. Treatment of ptosis. Another method is to directly use frontalis muscle to make frontalis muscle flap, move it down and sew it with the upper eyelid plate, and directly lift the eyelid with frontalis muscle strength to correct ptosis, which is called frontalis muscle flap direct suspension. This method does not need to work through intermediate links, avoiding the shortcomings of indirect use of frontalis muscle. It is suitable for frontalis muscle with good function, congenital or acquired ptosis, especially for severe ptosis, and can also be used for correction by other surgical methods. Because the operation is mobile, the patient can not only open his eyes but also close his eyes after treatment. In addition, the deep wrinkles on the forehead can disappear naturally after the operation, making the forehead look wide and flat, and patients can also get the cosmetic effect of double eyelids after the operation.
