Can fire needles treat hemangiomas?

Fire needle treatment for hemangioma is a method that many people will adopt, but it should be noted that this method needs to be used under the guidance of professionals to avoid adverse effects. The most common methods for treating hemangioma now are surgical treatment, laser irradiation, and photodynamic therapy, so we can choose the most effective treatment plan according to our own situation.

1. Surgical treatment of hemangioma:

The main treatment is surgical excision. On the one hand, skin grafting is needed after excision of the lesion. Full-thickness skin grafts or medium-thickness skin grafts are usually used, which have better effects. However, attention should be paid to choosing the inner side of the upper arm as the donor area. On the other hand, the lesion is large, and after surgical excision of the port-wine stain, it cannot be directly sutured. It needs to be repaired by transferring the adjacent skin flap, or using tissue expander therapy, that is, implanting a tissue expander around the lesion and removing it after 2 to 3 months. The local skin expansion is ready and then repair is performed.

2. Laser irradiation

The Q-switched pulse dye laser is particularly suitable for treating a variety of skin diseases by adopting a wavelength of 585nm, an ideal pulse width and a variety of light spots. The released 585nm laser is the peak absorption of hemoglobin and can penetrate the epidermis into the dermis. The extremely short pulse width can destroy capillaries without causing thermal damage to surrounding tissues, which can easily leave scars.

3. Fumeda (Hemoporfin) photodynamic therapy

Treatment principle: The second-generation new photosensitizer (Hemoporfin) is injected into the body through the intravenous route. Immediately after intravenous injection, Hemoporfin forms a peak concentration in the blood and is rapidly absorbed by vascular endothelial cells, while the epidermal cells absorb very little. Therefore, the distribution of photosensitizer forms an obvious concentration difference between vascular endothelial cells and epidermal cells. At this time, light of a specific wavelength that can penetrate superficially and be selectively absorbed by vascular endothelial cells is irradiated, causing heimporfin to produce phototoxic substances such as singlet oxygen, and the dilated and malformed capillary network in the affected area that is rich in heimporfin is selectively destroyed. The normal epidermis covering the dilated and malformed capillary network is not damaged because it does not contain heimporfin, and the normal deep dermis tissue under the dilated and malformed capillary network is protected because the laser penetration is shallow and it is difficult to reach an effective excitation amount.
