What are the treatments for hemangioma

When it comes to the treatment of hemangiomas, of course, we should focus on the correct methods. Hemangiomas are common in the oral cavity and maxillofacial area, so scientific methods should be used in treatment. Among them, pulsed dye laser has a better treatment effect.

1. Hemangioma is a congenital benign tumor or vascular malformation, which is more common in infants at birth or shortly after birth. It originates from residual embryonic hemangioblasts. Hemangiomas occurring in the oral and maxillofacial regions account for 60% of hemangiomas in the body, most of which occur in the facial skin, subcutaneous tissue and oral mucosa, such as the tongue, lips, floor of mouth and other tissues. A few occur in the jawbone or deep tissues.

2. Hemangioma Treatment Technology

1. Technical Introduction

Pulsed dye laser is the fifth generation dye laser system and a classic product of the global laser manufacturer, Candela Laser Corporation of the United States. It has a history of clinical application and has been effective in the treatment of skin vascular diseases for more than 20 years. The pulses used by pulsed dye laser are known as the "gold standard" for the treatment of skin vascular diseases. Equipped with the patented DCD dynamic cooling system, the treatment process is safe and comfortable. At the same time, pulse dye laser is also considered by the industry to be an effective laser system for treating port-wine stains.

2. 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.

3. Treatment effect

Photosensitizers previously developed in China, such as YHpD (photoporphyrin) and HpD (hematoporphyrin derivative), are all mixtures of multiple components with complex components, making it difficult to achieve stable and standardized quality control. They are also slowly excreted from the body, and the photosensitivity reaction of the skin lasts for 1 to 3 months after use, and even up to 6 months in some patients. This brings great inconvenience to post-treatment care and the patient's work and life.
