Nevus Of Ota

Ota's nevus
Q: Doctor Wang, my daughter has a patch of green birthmark on her face since she was born, now she is a high-school student but lacks confidence. I am afraid that it may also affect her university life, so I make up my mind to let her undergo the treatment. I have heard of a few hospitals and got to know from friends that the Ao Kang laser cosmetology center is the earliest one to be established in this field, the equipment is advanced, the doctor has vast experience, so I specially come here to get a more detailed information regarding the treatment.
A: since you have got to know a few hospitals already, I assume you also know the general information of this treatment, your daughter’s symptom is called the “tai tian mole”, we have been treating this disease for more than 6 years and with patients over 1000, the treatment is very effective, and we have not seen any unsatisfactory cases on the part of the patients, I can tell you responsibly that we can completely correct this skin defect of your daughter without any scar.



Q:is it really so miraculous?
A: the reason you think it’s miraculous is because this disease is thought to be incurable in the past, or even cured, there would be scars, however, modern medical technology utilizes the new laser type which can completely remedy this “incurable disease”, and totally solve the problem of the scar.

Q: so, what is the type of new laser treatment that will be applied on my daughter? Can you tell me in more details?
A: we will utilize the newest product Medlit IV Q Switch Nd from the American Ao Kang Company: YAG Laser, treatment with wavelength 1064nm.

Q: Doctor Wang, i heard from other hospitals that usually the wavelength of 755nm is applied, why it’s different from your wavelength?
A: wavelength of 755nm can also be applied to treat the mole, but its penetration depth and power is not as good as the 1064nm wave, and the interval between treatments is longer, it needs 9-12 months or even more, besides, to yellow race people, repeatedly using 755nm wave for treatment may cause the pigment on the spot of treatment to fade away in the later period. Therefore, I think using the 1064nm wave for treatment is safer and more mature.

Q: Doctor Wang, how many treatments are required for this disease? What is the interval period? Is the use of anaesthetic necessary?
A: normally it requires 4-5 times, the number of treatments also depends on the extent of the color difference, its position, the skin color, the physical condition and the gender. From past experience, the more significant the color difference, the better the treatment result, the white skin also yields better result than the black skin, male has better results than female, the people having brown specks on the upper and lower eyelid yield worse results. The best interval period is 5-6 months, sometimes it can be 9-12 months. Whether to have anaesthetic depends on the endurance level of the patients.

Q: is there any particular reaction and effect after the treatment that we have to take note?
A: after the treatment, there will be bleeding on part of the skin, swelling and the formation of scab. The scab will be shed after 10-14 days, keep it dry, do not dirt the wound surface with water, sweat or cosmetics.

Q: don’t you have any failure cases of the treatment during recent years?
A: to put it precisely, there have not been any failure cases, according to our own statistics, 2% of the patients have a little bit worse results than others, but they finally still achieve better results after undergoing more treatments.

Q: Doctor Wang, I have a last question, that is for the treatment, which plays a more important part, the advanced technology or the clinical experience of the doctor?
A: it seems that you really put in a lot of effort in the treatment of your daughter’s disease, your question is a bit professional. Nowadays, many people think that we can treat the disease as long as we have the right equipment, in fact, any advanced equipment is still managed by people. The laser treatment is different from the normal surgery, although the function of the equipment is very important, the doctor’s clinical experience has a more vital part to play, apart from the experiences in the setting of the various variables for the treatment, the choice of the light spot size, the density of the light spot coverage and the number of repetitions, the after-treatment precaution, the interval between treatments will all have a direct or indirect effect on the results of the treatment. But I can assure you that the doctors in the Shanghai ConBlo Plastic and Laser Surgery Hospital Laser Cosmetology Center all have 15-30 years of clinical experience in dermatology and 7 years of experience in the laser treatment. Our principle of service is that we use the best equipment and the best technique to achieve the best result. I hope my answer is satisfactory.
