Causes of lip defects. Lips are made up of skin, muscle, mucous membrane and lip red. Organizational structure is relatively speaking
Because of its complexity, we can't use tissues from other parts of the human body to repair defects at will. Lip defects are mostly caused by trauma.
Or infection, trauma or infection lead to different degrees of lip defects.
How to repair lip defect? The repair method depends on the degree of lip defect of the patient.
. The degree of lip defect is different, and the repair methods are different.
1) lip defects shall not exceed one third.
How to repair lip defect less than one third? For lip defect not exceeding one third
In these patients, the remaining lip tissue can be used for repair. The operation method is simple,
However, it should be noted that the lip redness of the healthy side and the affected side should be carefully measured before operation to prevent postoperative bleeding.
Now the situation of asymmetric lips.
2) The lip defect is more than half.
How to repair most of the lip defects? If the patient's lip defect is more than half,
Cross transfer of nasolabial groove tissue flap or contralateral tissue flap should be considered. If the patient lacks the middle part of the upper lip
If the damage is more than half, it can be repaired with nasolabial groove flap of upper lip tumor. The group of methods
Tissue flap should contain all the remaining available lip and nasolabial groove tissues as much as possible. If the patient is online,
The defect of lower lip accounts for about half, and the defect can be repaired with labial cross tissue flap. This kind of hand
It should be noted that the height of the lip should be determined by the height of the defect. The width of the lip is
Subtract the remaining length of the opposite lip from the total length of the lip, and then divide by 2. In this way, the ratio of upper and lower lips after reduction can be roughly
Same.
3) The lip defect is more than two thirds.
How to repair more than two-thirds of the defects of the lips? If the patient's lip defect exceeds 2/3 of the whole lip,
Lip-buccal tissue flap was used to repair all defects of lower lip. The operation is to design labial and buccal tissue flap.
Both sides are fan-shaped. After full-thickness incision, two fan-shaped tissue flaps are rotated downward and inward, and at the midline,
Sew up the edge of the wound. Due to the elasticity of buccal tissue, the left defect area can be directly pulled by layers.
Suture. Related surgical repair can be performed after operation.
4) complete lip defect
How to repair the complete defect of lip? The hospital can give patients lip defect reconstruction surgery. if
If the patient has only one side defect of the upper lip or the lower lip, it is necessary to use the lip tissue of the upper lip or the lower lip upward or downward.
The next transfer can be repaired. Three weeks after operation, one side of the mouth enlarged. If the patient's upper and lower lips are completed,
For the total defect, it is best to use the residual flaps of labial and buccal sulcus on both sides of the lip to reconstruct the lip, and repair the flap twice three weeks after operation.
