의느님답변📂ㅣ모낭을 이식하는 다양한 방법(수술 도구 : 포셉슬릿, 식모기, DNI, EZ 그라프터, KEEP) 의느님답변 77회

Hello, I’m Doctor Jaehyun Park at Dana Plastic Surgery. Because I received a lot of inquiries about this Today I am going to talk about the different ways to perform a hair transplant. Variety of ways to transplant hair (equipment) Sharp implanter, as you can see on the illustration

Is used by inserting the graft inside the needle And when it pierces the skin, at the same time it implants the graft which is the 1-step surgery The slit method is to make an incision first and then implanting the graft which is the 2-step surgery method. Sharp implanter is a 1-step method while slit method is a 2-step method.

However, for the slit method, the method varies On what equipment is used while performing the implant. The typical equipment’s are forceps slit, DNI slit, and KEEP. I am sure that by now you understand there are 1-step, 2-step methods. And for the slit method there are forceps, DNI, and KEEP methods. But when I consult with the patients, they are confused by

the terminology and concept of slit and sharp implanter. First of all, sharp implanters have a sharp tip Which pierces the skin and at the same time implants the graft which is a 1-step method. The shape of this sharp implanter varies worldwide. In Korea, the sharp implanter has been used for a long period of time and Generally, we call it the sharp implanter.

And the DNI surgery method is a type of slit method And people view the slit method as something a nurse would do. The slit method is not performed by the nurse. The slit method is just one type of method to implant the grafts. The slit method cannot be done by the nurse and there are a lot of hospitals that are done by doctors.

Therefore, saying that the slit method is only done by the nurse is a false fact. The pros and cons of each method First of all, lets have a look at the forceps. In the western culture, they used a method that punches 50100 hair follicles or 1524 grafts like this in the illustration. Since they had to implant this big chunk of hair, they had to use the forceps.

Implanting such big chunks of hair will result in unnatural looks therefore This method has not been used since the 90’s. As time passed, this big chunk of hair came down to one hair follicle. Then what are the pros and cons of forceps? It is simple to use on a bleeding scalp or a hard scalp and it is simple enough for the nurses to use.

This is the reason why the nurses would do the transplant because the amount of profit the hospital makes will be maximized And more than one surgery can take place at the same time It will be convenient for the doctor if there are enough nurses. However the down side is the possibility of damaging the graft and not being able to control the angle, direction, distribution

And also, the curl of the hair. Overall the time of the operation will be much longer. Which means the survival rate will go down. As you can see, the FUT graft has a lot of fatty tissue which will be easier To grab with the forceps. On the other hand, the FUE graft has limited fatty tissue Increasing the chance of damage to the graft with the forceps. To sum up, forceps method has 3 drawbacks.

Longer surgery time, increase in possibility of graft damage And also when the graft is pushed in, it could bend just like so. Whereas the sharp implanter method has superb control of angle and direction Which makes it easier to match the curl of the hair and the overall surgery time is much shorter. And the doctor will perform the surgery with no damage to the grafts.

The down side is that it takes a long time to get skilled And the overall profit of the hospital will decrease due to expensive equipment. The needle of the sharp implanter is expensive and the surgery requires extensive labor. This is the down side but for the patients, it is a good thing. There is almost no difference in survival rate between the slit method and sharp implanter Switzerland Doctor Albertini Conradin

had written on the hair forum about the FUE graft being smaller and weaker than the FUT graft And since there are less tissues around the FUE graft it is damaged easily. As the trend changed to the non-shaven FUE Doctors worldwide had started to use sharp implanters. You are looking at a graft being implanted with a sharp implanter.

The process is fast, precise and clean. Earlier, I mentioned that FUE graft and FUT graft is different. This is an image of a FUE graft where you can see that it is rather thin at the bottom. On the other hand, the FUT graft is thicker at the bottom. If forceps is used to insert the FUE graft It might be a little exaggerated but this is how it might bend.

As you can see, one of the hair follicles is bending which damages the graft. Look even by using force, it isn’t going in properly. This is the down side of the forceps. Doctor Mauro from Brazil presented DNI which made up for the weak points of forceps. He has visited our hospital and I have also visited his hospital as well.

So DNI method is done by inserting the graft in the DNI and implanting on the slit that was made beforehand. It has to be done quick and with precision And unlike the forceps it does not damage the graft It is implanted in a quick and clean manner. This is the DNI method. It can be seen as the evolution of the forceps method.

KEEP was invented by Doctor Koray Erdogan and is an equipment to implant the graft. I have some in my possession and have a great interest in this method. This method is used all over the world. This is a short clip of KEEP method. As you can see the graft that was implanted by the forceps is in bad condition.

These grafts were spotted regularly therefore the KEEP This equipment is called EZ grafter. I am not going to talk about this in detail because it isn’t used widely. It was invented by Doctor Xiao a Taiwanese-American. And is being promoted by Doctor Rassman at New Hair Institute. He uses the EZ grafter instead of the forceps

And said that it is much more superior at implanting the grafts. The most widely used method is the DNI. KEEP is used quite a lot while the EZ grafter isn’t as popular. Comparing the surgery time of the sharp implanter DNI and forceps, forceps method will take 1 hour for the slit And 35hours for implant which means it will take about 46 hours.

Sharp implanter will only take 2 hours and the DNI will take about 2~3 hours. I said that the down side of forceps method is the long surgery time. Then what is the advantage of a shorter surgery time? According to Limmer’s research, the survival rate is closely related to surgery time. He said that 1 hour will reduce the survival rate by 1%. 2 hours will be 95%, 4 hours 90% and 6 hours 86%.

In other words, you can see that as time passes, the survival rate of the grafts decreases. Generally, the golden time is about 6 hours. Since for each hour the survival rate decreases by 1%, if possible performing the surgery fast as possible will result in a higher survival rate. To sum up, forceps method is the slowest and Has a higher chance of damaging the graft. And also, the possibility of

nurses performing the implant. DNI and sharp implanter method is performed by a doctor which is more reliable. And there will be a rise in labor costs because the doctor will be performing the surgery. For the forceps method, if the nurses perform the surgery It could help cut down labor costs and increase profit for the hospital. The cost of sharp implanters is the most expensive

And then the DNI while the forceps is almost not used. I compared the pros and cons. Then what is the global trend? Then what is the global trend? There is a census of 2017 ISHRS that 52.6% of hair transplant surgery is performed using FUE method.

There are many world renowned doctors That everyone in the hair transplant field would know. And they are Jerry Wong, Harris, Shapiro, Mauro, Ruston, Devroye, Haber. They have about 20~30 years of experience In the field of hair transplant and have grown to a master in this field. They used forceps for over 20 years and all have

changed to the DNI or sharp implanter. Using the forceps nowadays is very old school. The trend has already changed to the DNI or sharp implanter. A lot of doctors around the world have recreated the sharp implanter or the DNI And are selling it all over the world. New equipment’s are being

Invented and sold which shows how sharp implanters are so popular. I will sum up for the last time. Forceps has been used globally for 20~30 years And it’s a conventional method. Now I think that it has done its job for a long period of time and there needs to be a change. The general trend right now is the DNI, KEEP and sharp implanter.

Doctors around the world are using DNI and sharp implanter that we have invented at Dana plastic surgery In other words, even if it is called slit There are different types of slit. Is it forceps slit? DNI slit? KEEP slit? And depending on which method is used, the results will have a huge difference.

Slit transplant is not the same as nurse transplant. In our case, the doctor will make the slit and perform the implant personally. We use DNI sharp implanter which is more advanced than the forceps. So, you have to know if it is the forceps or DNI and if the hospital is using their nurses for transplant. Do your research on hospitals and choose the right method for you.
