Grinding treatment of Ota is through controlled mechanical grinding of the superficial layer of the epidermis and dermis. After grinding, when the wound heals, the tissue structure of the skin surface can be changed, and the collagen fibers and elastic fibers of the dermis can be rearranged. Cloth, the remaining skin appendages (hair follicles, sebaceous glands, sweat glands) will quickly form a new epidermis with almost no scar on the wound surface. For the heavier degree of Ota can not be completely removed, combined with skin freezing to improve the treatment effect.

Therapeutic effect: can be maintained for one to several years. Appropriate people: people with Ota Recovery time: 1 week or so

Preoperative preparation

1. The surgeon and the doctor should make a comprehensive and in-depth preoperative conversation to understand the size, procedure, pain level, speed of recovery, possible effects, possible risks, and the doctor should understand the condition of the patient's face. Motivation, whether the expectations of surgery are in line with reality.

2, physical health check: Except for possible internal diseases such as heart, lung, liver, blood, previous surgical history, medication history, allergic history, etc.

3, stop drinking a week before surgery, stop aspirin, vitamin E and other vasodilator drugs.

Treatment and process

treatment method:

Grinding treatment of Ota is through controlled mechanical grinding of the superficial layer of the epidermis and dermis. After grinding, when the wound heals, the tissue structure of the skin surface can be changed, and the collagen fibers and elastic fibers of the dermis can be rearranged. Cloth, the remaining skin appendages (hair follicles, sebaceous glands, sweat glands) will quickly form a new epidermis with almost no scar on the wound surface.

Therapy process:

Skin dermabrasion, also known as dermabrasion, is one of the most commonly used methods in medical cosmetic skin resurfacing. Grinding is often performed by grinding with a grinding head to control the superficial layer of the epidermis and dermis. Mechanical grinding, repair mainly depends on the basal cells in the epidermis and the spine cells close to the basal layer, as well as residual skin appendages such as hair follicle wall, small sweat gland duct wall, sebaceous gland duct wall and other tissues, when the wound is healed, the skin can be made The surface of the tissue changes, and the collagen fibers and elastic fibers of the dermis are rearranged. The remaining skin appendages (hair follicles, sebaceous glands, sweat glands) will quickly form a new epidermis with almost no scars on the wound surface for treatment and beauty. An operation. Ota sputum occurs in the dermis and the lower layer of the dermis. The skin grinding method has certain limitations in the treatment of Ota, and it is better for the treatment of mild Ota, and it can be combined with cryotherapy for the severe Ota.

treatment effect

Dermabrasion is to smooth the epidermis of the uneven scar. After grinding, the remaining skin appendages (hair follicles, sebaceous glands, sweat glands) will quickly form a new epidermis, and the wound will be left with little or no scar. , to make the scars blurred to achieve the purpose of improving the appearance. Skin grinding is not only effective for depressed scars such as hemorrhoids, chickenpox, and smallpox. For pigments such as tattoos and dust explosions, the pigments in the skin are shallow and the skin grinding surgery has a certain effect.

The most important thing to prevent after skin grinding treatment is pigmentation, which usually occurs about one month after surgery. The peak is two months. After half a year to one year, a few have subsided after more than one year. In order to prevent the occurrence of pigmentation, it must be Do a good job of sun protection.

complication

1. Pigmentation: The incidence of pigmentation is about 30% in the country, while people with white skin are lighter than those with yellow skin or darker skin. Pigmentation usually occurs about one month after surgery, and the peak is two months. After half a year to one year, a few have subsided after more than one year.

2. Scar hyperplasia: the cause of complications caused by dermabrasion in the treatment of depressed scars. Scar hyperplasia can occur in any part of the grinding, but it is most common in the mouth and more women. The main cause of scarring is excessive grinding.

3. Infection: Due to the rich blood circulation in the face, the incidence of infection is extremely low. It is usually visible when doing large-area grinding in the summer.

Rehabilitation and care

1. Try to avoid water on the surgical site within 7 days after surgery.

2, to ensure that the surgical site is clean and prevent infection. If there is blood or secretion on the wound, wipe it with sterile saline.

3, after the operation can be applied to the local wound pressure bandage or cold pack, but the pressure should not be large, so as not to damage the eyes. Once bleeding occurs and severe hematoma occurs, you should go to the hospital for a follow-up.

4, after surgery should have a quiet and comfortable environment to recuperate. Do not watch TV or newspapers within 2 weeks after surgery. It is best to use a semi-recumbent position when sleeping in bed (to raise the pillow) to avoid excessive fatigue or low head position and increase wound swelling.

5. The wound will have some pain on the day of surgery, but it will gradually decrease over time. Patients should not rush to eat pain tablets, because aspirin drugs will increase wound bleeding.

6, avoid eating irritating foods, such as peppers.

7. Strictly follow the doctor's medication and return to the clinic.

Risk and prevention

1. Pain: Most people have no pain or only mild pain after surgery. You can take general analgesics as directed by your doctor.

2. Edema: After grinding, mild edema sometimes occurs, which usually disappears after 3-6 weeks.

3. Redness of the skin: It is the first complication after grinding. The length of time varies from person to person and usually disappears within 1-3 months.

4. Mildew rash: often occurs 2-6 weeks after surgery, should be further processed in the hospital.

5. Scar hyperplasia: can occur in any part of the grinding, and more women. Generally, mild scar hyperplasia can self-resolve and flatten in about 1 year. If necessary, dermabrasion is performed 1 year later to smooth the hypertrophic scar.

6. Infection: The incidence is low, mainly caused by excessive contamination of the wound surface and improper postoperative treatment.

7. Pigmentation: The incidence is high, usually occurs about 1 month after surgery, 2 months is the peak, and more often 6-12 months, a few more than 1 year subsided.

Physiology and aesthetics

Grinding often uses grinding head grinding to control the mechanical polishing of the superficial layer of the epidermis and dermis. The repair relies mainly on the basal cells in the epidermis and the spine cells close to the basal layer, as well as the remaining skin appendages such as the hair follicle wall. Tissues such as small sweat gland duct wall and sebaceous gland wall, when the wound is healed, the tissue on the surface of the skin can be changed, and the collagen fibers and elastic fibers of the dermis are rearranged, and the remaining skin appendages (hair follicles, sebaceous glands, sweat glands) A new epidermis will be formed quickly, leaving almost no scar on the wound to complete a treatment and cosmetic surgery.
