Blepharoptosis refers to the insufficiency or loss of levator palpebrae superioris muscle (innervated by oculomotor nerve) and smooth muscle (innervated by cervical sympathetic nerve), resulting in partial or total ptosis of the upper eyelid, which can cover part of the pupil in light cases and more than 1/2 in severe cases. Incomplete eye opening caused by decreased fascia function of levator palpebrae palpebrae. The skin at the end of the eyes overlaps, which makes people feel dull and sleepy. In order to open your eyes wider, you will unconsciously wrinkle your forehead and try to open your eyes, which will lead to wrinkles on your forehead. In severe cases, it will cause headache, shoulder pain and eye fatigue, which will not only hinder the appearance, but also affect vision and cause amblyopia.
First, how to judge whether you have ptosis?
Gently press the brow bone with your finger and open your eyes. If it can be opened normally, the muscle strength of the upper eye is normal. If it cannot be opened normally, the levator palpebrae superioris is weak and has the symptoms of ptosis. The greater the strength of opening eyes with the help of frontal muscle, the more serious ptosis.
Second, who is suitable for ptosis correction?
1, congenital ptosis:
It is caused by congenital hypoplasia or defect of levator palpebrae superioris, or nerve defect that dominates levator palpebrae superioris, mostly bilateral and sometimes unilateral.
2. Acquired ptosis: There are four causes: traumatic, neurogenic, myogenic and mechanical, of which myasthenia gravis is the most common myogenic cause.
3. The upper eyelid covers the black eyeball to 1/3.
4. I often hear people around me say that I am always sleepy.
5, when you open your eyes, you need to open your eyes with the power of lifting your eyebrows, resulting in an increase in head lines.
Third, how to correct ptosis?
1. Moderate and mild ptosis: shortening levator palpebrae superioris muscle to improve ptosis.
Shortening levator palpebrae superioris can be roughly divided into two methods: transconjunctival incision (internal incision method) and percutaneous incision (external incision method) or conjunctival skin combined incision. It is suitable for people with bilateral or unilateral mild or moderate congenital diseases, 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. The reason for this is that it can keep the original walking and moving direction of muscles, meet the physiological requirements of eyes, and the postoperative effect is ideal.
2. Severe ptosis: Frontal muscle lifting or combined fascia sheath suspension (CFS) was used.
There are two ways to improve the frontalis muscle: one is to connect the tarsus and frontalis muscle with various materials or tissues, and indirectly correct blepharoptosis by using frontalis muscle strength.
Another method is to directly make a frontalis muscle flap with frontalis muscle, 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 direct suspension of frontalis muscle flap. 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 cases where other surgical methods fail to correct ptosis.
Combined fascia sheath suspension: Combined fascia sheath (CFS) refers to the deep pterygoid ligament of upper eyelid, which is elastic and completely parallel to levator palpebrae superioris muscle. During the operation, we can use the strength of the superior rectus muscle and the residual levator palpebrae superioris muscle through this deep pterygoid ligament to replace the levator palpebrae superioris muscle without eye opening strength to complete the purpose of eye opening.
4. What is the difference between ptosis repair surgery and ordinary double eyelid surgery?
Simply put, ptosis is a congenital eye eyelid deformity, and the eyes can't be opened normally, which is not only an aesthetic problem, but also affects the visual field and vision, and will also lead to the increasing lines on the head.
Double eyelid plasty is aimed at almost all healthy eyelid conditions, which will not affect the visual field and vision, but the aesthetics is not enough, which is completely different from ptosis.
From the difficulty of operation, the difficulty of blepharoptosis repair is much greater than that of ordinary blepharoplasty.
Five, if the eyes have ptosis symptoms, only do double eyelid surgery without ptosis correction, what will the effect be?
The eyes with ptosis only made double eyelid surgery, but did not adjust the strength of levator palpebrae superioris. When you open your eyes, the force of lifting your forehead and eyebrows can't reach your eyelids, so you can't solve the problem of ptosis. You can only open your eyes with the help of forehead muscles or eyebrows. The effect is only to make the lines of double eyelids bigger and the eyes look more sluggish and sleepy than before the operation. Because of the individual differences of patients, different surgeons will have different postoperative effects. Therefore, we should not only follow the general principles, but also combine the doctor's own clinical experience when choosing the operation method. Here, patients are required to find an experienced professional doctor to treat ptosis in order to have beautiful eyes.
