Nevus of Ota was first reported by Dr. Ota in 1938, so it was named “nevus of Ota”. Nevus of Ota (nevus of ota) is a pigmented lesion of the skin in the distribution area of the trigeminal nerve (mainly the 1st and 2nd branches) and often the sclera and other tissues, caused by abnormal differentiation of melanocytes in the skin due to heredity or some intrauterine causes. Clinically, it is characterized by brownish-blue patches or patches of skin around the eyes and face, so it is also called brownish-blue nevus on the palate of the eyes and ocular dermal melanocytosis. More than ten years ago, not many people were concerned about nevus of Ota, but today, more and more parents of children with nevus of Ota are eager to get treatment as soon as possible with the development of treatment technology, the continuous maturity of nevus of Ota treatment technology and the continuous improvement of people’s living standard. In the treatment team of nevus of Ota, there are even many anxious parents who bring their babies and toddlers of several months to the clinic. Then the question arises, do nevus of Ota need to be treated early? Is early treatment more effective? When is the best time to start treatment? First, when is it better to treat nevus of Ota? According to the traditional theory and practical experience, we used to suggest that it is more appropriate to wait until teenagers before treatment. First of all, the cause of nevus of Ota is still unknown, and all the treatment methods nowadays, no matter how high-tech they claim to be, are only symptomatic treatment, which can only treat the symptoms but not the root cause. Generally speaking, after the onset of the disease for more than seven or eight years, most of the conditions will slowly stabilize on their own, and after the condition is stabilized, even if no treatment is given, the condition will rarely expand again. When the condition is stabilized and then treated, the recurrence rate is probably lower, but even if the condition is treated before it is stabilized, there are still more recurrences even if the nevus of Ota has completely disappeared after treatment. Secondly, laser treatment is still painful. Even with the new picosecond laser treatment, although the energy used is theoretically only one third of that of the previous nanosecond laser, and the pain is relatively lighter, it is still very painful for children. The younger the child, the lower the tolerance of pain. The same pain may be tolerable for adults (even without any anesthesia), but it may be unbearable for children (even if local anesthesia has been used). Therefore, the earlier the nevus of Ota is treated the more obvious the pain is. Moreover, the younger the child is, the less he or she will cooperate. If treatment is to be done under general anesthesia, there is a certain risk of general anesthesia, and the younger the child is, the greater the risk of general anesthesia, because after all, the younger the child is, the less developed the nervous system is. Existing information shows that nevus of Ota only affects the aesthetics and has little effect on the body, so to risk general anesthesia for the treatment of nevus of Ota, I personally suggest that there is no such need. Whether to treat nevus of Ota or not only affects the aesthetics, but if general anesthesia causes problems for the sake of aesthetics, is it a gain or a loss, do you think? Of course, you may also hear that you don’t need general anesthesia, but local anesthesia is fine. Local anesthesia can only relieve 60% of the pain, and adults generally find it tolerable with local anesthesia, but for children, it is better to be useful than useless. Do nevus of Ota need to be treated early? Is the effect related to age? No, the treatment technology for nevus of Ota is very mature now, and the treatment effect is very good even at an older age, so there is no need to worry about such nonsense as the best treatment period has passed. On the contrary, children have tender skin, so they cannot use too much energy when they play, and they must be treated more times than adults. Now is the age of high technology, treatment effect is good, relying on the development of science and technology, as well as the doctor’s operating techniques, if the effect also depends on the age to decide, then what is the difference with the day to eat, what is also called high-tech? Third, must be anxious to treat, how to treat? Although there are all the above reasons, but now many parents are very anxious mentality, each said if not treated, how deep the child’s future psychological shadow and so on. Often, while the child itself cries out and refuses to be treated, the parents are worried about the so-called psychological shadow and are determined to treat it early. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. So at least wait for more than half a year, it is best to start treatment after one year, at least relatively safe. As for within 3 years old, that is because, the treatment is more painful, to let children cooperate with their own, is simply a fool’s dream, are aggravated hard to grasp to do, but too big children, grasp can not grasp, want to do can not do, so within 3 years old, relatively speaking, children can still grasp, either wait for 13 years old and above, they understand, want to treat it. There is also the fact that the number of times children are treated is actually more than adults, because children do not cooperate, moving around struggling, even if they want to give you serious treatment, it is difficult to do, and children’s skin is tender, the energy can not play too big, so the number of times are more, and post-operative care to be more trouble, especially within the age of 3 years old children do not know what to do, parents must often keep an eye on the post-operative, or in case of accidental wound by the If the wound is accidentally buckled by your own hand, it will not look good if you leave a scar.
