This treatment method, also known as "skin and soft tissue expansion therapy", is a method of placing a skin and soft tissue expander under normal skin and soft tissue, increasing the liquid content in the expander, exerting pressure on the surface skin and soft tissue, expanding it to produce new "extra" skin and soft tissue, covering the wound with the newly added skin and soft tissue transfer and repairing the defect.
Question 2: What does the dilator look like? What specifications do you have?
The main body of the dilator is a silicon capsule, and one end of the dilator is connected with a syringe. According to the shape, it can be divided into cylindrical, kidney-shaped and spherical. The sizes are 10ml, 30ml, 50ml, 80ml, 100ml, 200ml, 300ml, 400ml, 600ml and 800ml, which can be seen in Baidu pictures.
Question 3: What kind of situation is suitable for dilator treatment? Where is the extensible part?
Many cases are repaired by skin and soft tissue expansion, such as various body surface scars; Hair loss, capillary hemangioma, body surface tumor; Skin melanoma and verrucous nevus; Organ reconstruction (such as breast reconstruction, nose reconstruction, external ear reconstruction, etc. ).
According to the part to be treated, the common parts are: the middle and outer auricles of the hair on the top of the head, the skin on the forehead, cheeks, neck, chest, abdomen and back.
Question 4: How long does it take to treat scar with dilator? Is it okay for children?
It is generally recommended to perform surgical treatment after 3-6 months, because the scar texture is hard in the short term, and the longer it is, the softer it is, and the easier it is to achieve better results.
As for children, children treated in hospitals are generally after 3 years old. It is not a problem for parents to take good care of them. Then parents worry that their children are in too much pain. In fact, the process of expansion is not so painful, but the operation is a bit painful, but it is also the effort and price that must be paid to get rid of the scar.
Question 5: If dilation therapy is used, how many operations are needed? How many dilators can be buried simultaneously?
If you use a dilator to treat small scars, it will be fine twice. The first operation, minimally invasive implantation of dilator, no pain. Minimally invasive wound is very small, just a few stitches. The second operation, after expanding the skin, take out the dilator, remove the scar and sew up the wound. If the scar is large, you can consider burying multiple dilators at the same time, but you can't blindly ask for more. The number of expanders should be determined by combining the scar site and the physical recovery ability of scar friends.
Question 6: What are the precautions before and after operation and before wound healing?
Before operation
1, two weeks before scar repair surgery, do not take drugs containing aspirin, because aspirin will reduce platelet coagulation function and lead to bleeding, do not take diet pills, do not eat hot pot, salvia miltiorrhiza and other blood-activating foods.
2. Patients with hypertension and diabetes should inform the doctor of their condition at the time of initial diagnosis, so that the attending doctor can confirm the operation plan.
3. Make sure that you are healthy before scar repair surgery, and there is no infectious disease or other body inflammation.
4. Don't put on makeup before scar repair surgery.
5. Women should avoid menstrual period.
6. Take a bath several times before the operation, each time for a period of time, to minimize the amount of bacteria. Hair and nails should be cut short.
1 after operation, and try to avoid water accumulation in the surgical site within 7 days after scar repair.
2, scar repair surgery to ensure the cleanliness of the surgical site.
3. Avoid eating irritating foods such as peppers after scar repair.
4. The incision is partially fixed. If you are facing the neck, you should also consider the influence of speaking and eating on the wound, try to avoid activities and eat food that is easy to chew.
Question 7: How long is the dilator treatment?
The embedding time of the dilator should be 4 ~ 6 months, but the dilator can generally be expanded to 2 ~ 3 times the size, and a longer time is better according to the specific situation of the patient.
In case of dilator infection, skin vascular bleeding, skin trauma, etc., not only can not inject water as scheduled every week, but also pump water to decompress according to the situation, giving the skin a certain recovery time, which will delay the time.
Question 8: When will the water injection start? How many times a week is appropriate? Is it painful?
After suture removal after dilator implantation, a small amount of water can be injected to expand the skin. Early dilator is not fully filled, pumping water twice a week is more common, and once a week is more appropriate after stabilization. It doesn't hurt every time you draw water, and the pain caused by scalp acupuncture is still very small.
Question 9: What should I pay attention to when injecting water?
First, the amount of water injection, first of all, there is a feeling of expansion after each water injection, suggesting that this water injection should be stopped. The doctor should also consider your skin color to determine the amount of water to be injected.
Second, the climate in spring and autumn is dry, so some neutral moisturizing cream or cream should be used externally to prevent dry skin. Sunscreen and mosquito bites in summer.
Third, clothes should be loose, and cotton is the best texture. If the scar is on the face and neck and you need a scarf, you should buy a scarf made of pure cotton and silk, and separate the dilator from the collar and zipper to prevent scratches. Don't have sliders and buttons on coats and pillows.
Fourth, when cooking or eating at ordinary times, it is necessary to avoid hot oil and hot water splashing directly on the dilator. Avoid crowding in the street.
Question 10: to what extent did it expand before the second operation?
Generally speaking, the volume of dilator should be 0.5 ~ 2 times of the original volume of 65438+ (estimated), but the scar area is different, so it is not possible to judge whether surgery should be performed only from the volume. Generally speaking, if you have the following three characteristics, you can consider a second operation.
Large volume: Generally, the dilator can achieve good expansion effect after water injection, so it is relatively large and has the feeling of "fruitful".
Thin skin: smooth skin, high transparency and clear blood vessels. The expansion of the dilator is like blowing a balloon. After the sphere expands, the wall of the sphere will become thinner. Practice has proved that the thinner skin has low shrinkage rate and high utilization rate.
No defect: that is to say, there is no trauma or boil on the skin of the dilator before operation, and the skin is smooth and delicate.
Then, combined with the doctor's judgment, I believe that your attending doctor will choose the operation opportunity for you in the best case.
Question 1 1: The surgical incision of the dilator is relatively long. Will it be obvious after operation?
The problem of long incision is inevitable in dilator operation, but if you are not a person with scar constitution, you can still achieve better control effect, so don't worry too much. The best effect I have ever seen is that the incision line is not clear at all.
Question 12: What should I do when I rest at home after the wound is healed?
After the dilator is taken out, you can go home to recuperate after taking out the stitches. During this time, we should pay attention to the problem of sticking to the external elastic sleeve and scar-inhibiting drugs. Because the wound will proliferate quickly within three months to six months, we should stick to the methods of physics and medicine to prevent proliferation to the maximum extent.
Question 13: How soon can I go to the hospital for reexamination? Is there any follow-up treatment?
You should get in touch with the doctor in about 3 months and go to the hospital for reexamination, so that the doctor can give advice according to everyone's recovery.
Question 14: What is the approximate cost?
Because dilators are big and small, they can't be the same, so for example:
If a 200 ml dilator is used, the cost of hospitalization and operation may be about 6 thousand to 7 thousand when buried, and the second operation is slightly more than the first one.
If two 200 ml dilators are implanted at the same time, the cost of operation and hospitalization may be 8 thousand to 9 thousand, and the cost of the second operation is about 12000 to 15000.
Question 15: What should I go to the hospital in time?
Severe burns, abrasions, infection, severe pain, and the dilator turns purple all over or partially, resulting in blood supply disorder. All these situations should be dealt with by the doctors in the hospital in time.
Question 16: What should I do if the dilator turns over?
The so-called dilator turnover means that when the dilator is placed, its bottom surface rotates more or less outward around the long axis. It often happens when the dilator is not fully opened and the skin is slack. From the appearance, there is an obvious protrusion on the expanded skin, or you can feel the protrusion by touching it with your hand. This is because the catheter outlet that should be at the bottom of the dilator appears under the expanded skin. This can be completely avoided as long as we pay attention to the amplitude and degree of exercise at ordinary times.
The general corrective action is to relax the skin around the dilator, gently massage it with your hands and push it in the original direction. If you are not sure about the direction, please go to the hospital for help.
Question 17: What do you usually eat?
Eat more foods that are good for skin growth, such as fresh fruit, protein, a little fat, trotters, chicken feet, pigskin and other foods rich in collagen, and of course, combine with moderate aerobic exercise. Taboo foods generally refer to spicy or easily irritated foods, such as peppers, ginseng and velvet antler.
