Laxometer II

Often times we receive inquiries at US Hair Restoration about the latest hair transplant technology, and we feel obligated to spread the news about the latest hair transplant technology.  We are excited about the new generation of Laxometer, the newest hair transplant device invented by Dr. Parsa Mohebi. The Laxometer II is a handheld device which revolutionizes the art and science of hair restoration. Being in the growing sector of the cosmetic surgery arena, progressive updates on hair transplant new technology is critical.

Applications

The revolutionary Laxometer II increases the number of hair grafts which can safely and precisely be transplanted in one surgery. A hair transplant of more than 3500 hair grafts once upon a time took two or more surgeries to complete, but with this latest technology in hair transplantation, it can be done in only one procedure.

The Laxometer II, the new technology in the hair transplant industry, is basically a measuring device which is used to calculate the laxity of one’s scalp. An accurate measurement of scalp laxity is critical when determining how large the donor strip can be. This latest breakthrough hair transplant technology gives a precise measurement which can be increased as a result of patients actively doing daily scalp exercises. The larger the available strip, the more grafts can be made available for transplantation.

At the International Society of Hair Restoration Surgery’s 19th Annual Scientific meeting in Alaska in September 2011, Dr. Mohebi unveiled his new invention for purchase to all hair transplant surgeons. This latest technology in hair transplant surgery was welcomed with anticipation and applause as it will help to continue the industry progressing forward.

Q:

I recently had a hair transplant consultation with Dr. Mohebi but just had a few quick questions to clarify the information told to me in my consultation.

Dr. Mohebi recommended 3000++ grafts grafts to me. With an FUT hair transplant procedure involving 3000++ follicular unit grafts, what is the typical range of units that are actually harvested? And what proportion of the units harvested typically transplant successfully?

A:

With Dr. Mohebi’s recommendation of 3000++ grafts, he hopes to achieve somewhere between 3000-4000 successfully transplanted grafts.

While we cannot offer an exact number during your consultation, these are his recommendations based on your hair loss pattern, your personal expectations, density of hair on donor area and for strip surgery, scalp laxity.

If doctor Mohebi had recommended scalp exercises to you, that means you can help to improve the laxity of the scalp and increase the number of grafts that could be safely removed by performing the recommended exercises.  This helps the number of transplanted grafts to go more toward 4000, if you successfully perform scalp exercises.

I have not been answering any questions in our hair restoration blog for a few days because I am in Florida as one of the invited faculties members in the hair restoration surgery workshop of International Society of Hair Restoration Surgery (ISHRS).  The meeting is held annually each year in the beautiful city of Orlando and prominent hair transplant surgeons from all over the world get together to share ideas and teach the future generation of hair transplant surgeons the science and art of hair transplantation.

I had one lecture yesterday on my invention of the Laxometer and the method in which we measure the laxity of donor area in large hair transplant surgeries.  We also discussed our new method of sequential strip removal that guarantees removal of the maximum number of grafts while still assuring the safety and quality of the hair transplant.  As a hair transplant surgeon that performs a majority of hair transplant procedures with large number of grafts, we have developed this method geared for hair loss patients with advanced classes of baldness.

Workshop Faculties: Dr. Parsa Mohebi, Dr. David Perez and Dr. Mark Mckenzie

These verbal lectures are usually followed by surgical workshops in the afternoon.  I will be demonstrating use of the Laxometer in the surgical workshop again tomorrow.  Dr. Mark Leavitt and Dr. David Perez, the main organizers of the hair transplant workshop, did a great job arranging the event which is a big step forward in education of hair transplant surgeons.

I will be back in Los Angeles next week and will continue answering your hair loss/hair transplant questions in the hair restoration blog upon my return.  I will also make sure to put a note on what was new in our Orlando Hair Transplant Work Shop this year. Be sure to stay tuned to the blog for this and all future updates.

In a standard hair transplant procedure (follicular unit transplant through strip technique), having adequate scalp laxity is crucial to avoid complications in the donor area. Doing so has required the individual judgment of an experienced hair transplant surgeon but still leaves room for human error. If the surgeon removes too wide of a strip, there may be issues with wound closure, a visible wide scar, telogen effluvium (hair loss around donor wound), and/or skin necrosis. Areas around the scalp most at risk are the mastoids or the area behind ears.

Laxometer has been designed to minimize hair transplant complications (in 15th annual meeting of International Society of Hair Restoration Surgery) by helping assess scalp laxity more accurately prior to a hair transplant procedure. After the first assessment, the patient then practices the scalp exercise to increase mobility and is then reassessed the day of surgery. The more laxity the patient has the higher the chances of increasing the number of grafts that can be transplanted in a single hair transplant.

We performed a study on 37 different patients to assess the success and functionality of laxometer. In all of these patients, half of the donor wound was closed during the procedure to evaluate the impact of donor excision on the laxity of the donor area. Three (3) locations of donor area were assessed before and after incisions were made:

I.    Right side
II.    Mid line
III.    Left Side

The laxity of the sides were measured approximately 10-15cm above the mastoid bone from the midline. The incision was made using a double bladed knife to insure uniformity.

After excising the first half of the strip, laxity was measured on the secondary section prior to full incision and excision. If laxity has been compromised due to the first excision and closure, then the second incision will be smaller. Out of the 37 patients that underwent follicular unit transplantation through strip technique, only six (6) patients required a smaller incision due to a lesser laxometer reading caused by reduction of laxity. Our study shows that wound tension:

I.    May increase on the secondary side in some patients (~16% chance)
II.    May not be an issue in most patients (~84% chance)

Laxometer helps determine scalp laxity before, during, and after a hair transplant procedure for optimal excision and closure. It helps determine the maximum amount of tissue that can be excised safely helping increase the chance of more grafts that can used a single session. This practice is best applied on patients undergoing a mega-session hair restoration in which over 2500 grafts are being transplanted in one hair transplant session.

Hi Doctor,

My son has had a hair transplant years ago with old techniques and he has bad hair transplant scar now. He now wants to shave his head, but the scar of hair transplant on the back of his head may become exposed. Do you perform hair transplant scar repair or do you recommend any procedure that can help with hair transplant donor scar coverage?

Answer:

Hair transplant with strip technique can cause a linear scar that could be visible on the back of head if the patient wants to shave his/her head. A hair transplant scar is not limited to a bad hair transplant technique and it might have to do with one’s personal healing process too (some people are generally better healers compared to the others).

The good news is that we have methods to minimize the size of the scars nowadays and if you have bad hair transplant scars from bad transplants in the past, there are several new methods that can help improving the appearance of the donor scar. A hair transplant scar could be improved by repair of linear widened scars with different methods that we perform at our Los Angeles office of US Hair Restoration. Dr. Mohebi is the inventor of the axometer, a device that measure the laxity of the scalp precisely before hair transplant surgeries. Good measurement of the scalp laxity is one of the best ways to minimize development of donor wound complications and widening of donor scar and the Laxometer is the device to do these measurements.

One method is through simply excising the scar. Excision of the donor scar may be helpful for some donor scars. After removing the scar, hair transplant surgeon can close the skin with the trichophytic closure method in which a small wedge on one or both sides of the skin edge is removed and the skin is closed primarily. Trichophytic closure allows some hair follicles to grow new hair into the final scar. Presence of hair helps making the hair transplant scar become invisible.

Hair transplant donor scar coverage could also be performed by transplanting hair into the scar. Hair could be harvested from other areas using FUE or mini-strip techniques. Again, presence of the hair inside scarred area could trick the discriminating eye and the scar would become less detectable. Patients may need more than one hair transplant procedure into the donor scar for minimizing the difference between the densities of hair in scar and surrounding areas.

The last method that could be used to camouflage the linear scar is by tattooing the scar. People who plan to keep the hair very short can easily tattoo the scar with the figures of short hairs so it seems that there are some hairs present in the scar area, which can help minimizing the visibility of the scar.

Question:

I am a 40 year old man. I had a hair transplant 15 days ago and have my sutured removed 5 days ago. I am generally very active, but my doctor said that I can not exercise intensively for first 3 months after surgery. When do you usually say is safe to resume heavy exercise.

Thanks A lot!!

Answer:

Dealing with daily activity and sports after hair transplant surgery is a concern for many patients who are physically active and want to get back to their normal routine as soon as possible. There are two areas of concern after a hair transplant surgery. First, you may lose newly implanted grafts when doing contact exercise like wrestling. This can only be problematic within the first 4 days after surgery. Research has shown that after this period the hair graft is completely healed and infused in surrounding skin. Usually even pulling the hair after this period of time doesn’t have an adverse effect. The follicle stays in place and is capable of making a new mature hair.

The second concern is with the donor area, which is primarily closed by sutures or staples. Using Laxometer can help up to close donor wound with not much tension on the wound edges. The healing of the donor incision follows the general wound healing rules. The process of healing starts from the moment the wound is closed. The wound heals primarily within a few days from the time of hair transplant and any vigorous activity should be avoided within the first two weeks. After two weeks, the wound is practically healed, but the strength of this newly healed wound is nowhere close to normal skin. The wound needs a few months to get back to its final strength. However, regular aerobic exercise is not contraindicated even the day after surgery.The activities that you should be avoiding are: Anything that increases the tension between the edges of the healingwound in the donor area, such as weight lifting and other exercises which involve intense bending of the neck. You should wait at least 6 months for this type of exercise in order to prevent opening of the wound or widening of the final scar.
