According to different causes, ptosis can be divided into congenital and acquired. Acquired ptosis includes trauma, reflex, primary ptosis of nervous system and occult ptosis. According to different degrees, it can be divided into mild ptosis, mild and moderate ptosis and moderate and severe ptosis. The treatment of ptosis is mainly surgical correction, so pay attention to the choice of surgical opportunity. For example, congenital and mild ptosis, it is better to have surgery after 5 years old. Mild, moderate and severe ptosis usually occurs at 1.5 years old. If there are other eye diseases, treat other eye diseases first and then plastic surgery. For acquired ptosis, the etiology should be treated first, and if it fails, plastic surgery should be considered. It must be noted that if the upper face is slack, it will cause pseudomyopia without early treatment and should be corrected as soon as possible.

1. ptosis is due to the lack or absence of levator palpebrae superioris muscle, which makes the upper face relax and covers part or all of the pupils, which is easy to cause visual impairment. There are two reasons: congenital and acquired. Congenital upper face relaxation is both postnatal and hereditary. The operation time must be determined according to the weight of the upper face and lower body. If all obstacles are covered enough to cause pseudomyopia, surgery should be performed as soon as possible, and levator palpebralis reduction and blepharoptosis correction should be selected. Acquired facial relaxation is more common in oculomotor nerve paralysis and numbness of cervical central nervous system (caused by head and neck surgery), so it is necessary to carry out neurotrophic drugs and surgical treatment at the same time.

2. The treatment of ptosis depends on the etiology and level, and the treatment methods are also different. Blepharoptosis caused by muscle weakness of the head or other nervous system abnormalities, as well as blepharoptosis caused by inflammation of the mass, must be treated by drugs or surgery. Only when the etiology is removed, the condition is stable and ptosis still exists will the visual function and appearance be damaged. At this time, surgery is needed to correct ptosis. According to the degree of ptosis, the choice of operation is different.

If ptosis is light, levator palpebrae superioris muscle reduction can be done to strengthen the energy of levator palpebrae superioris muscle and make the upper eyelid of both eyes reach a sufficient relative height; If the ptosis is serious, the levator palpebrae superioris muscle strength is not enough. Usually, we must do the operation of frontal muscle suspension training, and use the energy of frontal muscle to make the upper eyelid reach a sufficient relative height to correct ptosis. Therefore, ptosis depends on the etiology and the degree of ptosis, so different treatment methods will be chosen, and most of them must be operated. When the ptosis gazes forward, the position of the upper eyelid margin is abnormally lowered, which does not cover the eye pupil, but it will affect the appearance. In severe cases, or all the pupils are covered, endangering visual function.
