The symptom of congenital ptosis is that the upper eyelid covers most of the pupils or completely covers the pupils, accompanied by congenital muscle weakness of the upper eyelid, which is a disease that exists from birth. People with this disease can't keep their eyes open because their upper eyelids are difficult to lift. When looking at people or things that can be seen by normal people, they should look back and face the sky. Congenital ptosis is mostly inherited in the family, which is caused by oculomotor nerve problems that innervate levator palpebrae superioris. The onset can be unilateral or bilateral. Some are accompanied by epicanthus, ptosis and other deformities. If the upper eyelid is covered for a long time, the field of vision will be reduced, which will cause amblyopia. Because of the compensatory transition to the frontal muscle, the eyebrows will stare up and it is easy to leave wrinkles. A few children even have cervical dysplasia. Therefore, children with ptosis should have plastic surgery in time. Treatment of congenital ptosis: There are different methods to correct ptosis according to different reasons. For congenital ptosis, surgical correction of clinical experience is quite effective. L, levator palpebrae superioris shortening is suitable for children with mild ptosis, and levator palpebrae superioris shortening is used to treat congenital ptosis in order to achieve the purpose of lifting eyelids. 2, frontalis myofascial suspension frontalis myofascial suspension treatment of congenital ptosis is to use a small piece of autologous thigh fascia to connect with frontalis muscle and upper eyelid, and use frontalis muscle contraction to strengthen the strength of levator palpebrae, because the suspended fascia may become loose in the future, sometimes affecting the surgical effect. 3. Frontal muscle flap uses the contraction of frontalis muscle to strengthen the function of levator palpebrae superioris muscle, so that the eyelid muscle completely loses its function and the correction of ptosis is better. Its advantage is that only a small incision is made at the eyelid fold (double eyelid line), and the frontalis muscle flap can be separated and transferred to complete the operation, which plays the role of eye expansion and has a reliable and lasting effect. Avoid the pain of cutting the thigh fascia, and at the same time form double eyelids to make the eyes burn more beautifully. Finally, experts pointed out that careful examination must be carried out before the treatment of congenital ptosis, and a good differential diagnosis is helpful to choose the appropriate surgical method. At the same time, postoperative care is also very important. If there is no good nursing after operation, it will also lead to poor results and various problems. Therefore, the treatment of congenital ptosis needs to be highly valued to avoid unnecessary harm.
