The Use of Sapphire Blades in Hair Transplant Surgery

Human history has always been marked by the development of specific tools for various surgical operations. It is generally accepted among experts that the success of a surgical operation is directly related to the use of the right surgical tool. Previously, hair restoration surgeries required heavy tools and larger blades, while smaller technical advancements facilitated the arrival of smaller tools. In our times, when significance is placed on aesthetics and naturalness, surgical blades and surgical tools have also taken their place in this context. It is possible to say that the use of sapphire instead of metal for hand tools, especially in the field of hair transplant surgery, has gained an important place in the use and improvement of handwork due to the increasing number of frequently performed hair transplant operations. It is a big part of the world offering positive results from this practice.

Patients diagnosed with androgenetic alopecia constitute a significantly large segment of the demands in medical aesthetics. Patients demand less invasive and scar-free surgical interventions to preserve their continuity of life and social life. In this environment, today, innovative sapphire blades have been added to the collection of surgical tools used with preferences in the clinics for the techniques used. In this article, which is based on a frequently asked question, the subject of the use of these new tools (sapphire blades) will be thoroughly reviewed in terms of application and technique preferences every aspect of the coin. In our modern medical practice, the reasons for the use of such devices and the advantages they provide should be clearly understood.

Overview of Hair Transplant Surgery

Hair loss is a major aesthetic issue. Hair transplant surgery has played a significant role in the treatment of hair loss. Conventional methods are based on an open donor area, visible postoperative scars, and slow postoperative recovery. As techniques advance, it becomes important to ensure accurate transplantation—it is critical, both in the donor and recipient areas, to create holes and place the graft according to the correct plan. Not making the recipient can result in deprivation ischemia, ecchymosis, and wounds. On the donor site, the dangers are pseudocyst, tumor, ischemia, and cosmetic problems. Globally, the first method of hair transplantation moved from large punches into large incisions and many blade holders to fine micro-channels and mechanical methods. Apart from slitting techniques, the electronic method was utilized as a lean hook and electronic motorized serration. Proper labeling is key in surgical hair restoration to provide accurate graft placement and to obtain good graft yield.

A hair transplant surgery may need to transplant up to 5000 or several hairs in a session of 2 to 7 hours in a single surgery. Currently, manual and motorized techniques are used for hole preparation, but the precision of the custom-made blade holders is less. The motorized holes have several advantages, but they may cause more transection. Various conditions can lead to hair loss. Androgenetic alopecia is the most common cause confronted by men and women. Post-traumatic androgenetic hair recession may occur as a result of pulling injury. Body hair can be transplanted in order to camouflage the scars. Hair grows in natural groups of 1 to 4 hairs, but Black males and women typically have a high follicular unit group. Small hair graft units have no value because you will end up producing the doll hair effect.

Evolution of Surgical Blades

The ways and means to perform surgery have always evolved through time until today. The earliest surgical procedures prior to anesthetics necessitated swift cuts to reduce the time a patient was in pain. Surgical blades would have evolved from the earliest days of surgery in ancient times. However, their shape would have been mimicked elsewhere in tool design, ruling them out as a readily available target for styling development. Blades in the early days of surgery would have been fashioned from flint or obsidian, thus forming a sharper edge than could be realized with the early smelted steels. For thousands of years, the spearhead shape became the de facto shape for cutting and sewing skin, muscle, and bone as surgery moved from being crude, bloody, and quick to a more delicate, planned endeavor.

During the steel revolution, steel artifacts of all shapes and sizes emerged from the smiths’ workbenches; it was not long before this innovation found its way into surgery. Blood and blood diseases led to research on how to stop blood flow, while wishing to return to more gentle, careful surgery. The first to apply a blade to tissue in a parallel fashion to the cutting axis, reducing the compression and expanding nature of the blade, is noted. Wooden-handled, high-carbon steel blades, straight cutting edges are defined as the first scalpels and blades as we would know today. Steel blades were the blades of choice for the preceding two centuries and have proven to be effective in the hands of trained surgeons and scientists. However, even with years of training, skill, and dedication, a steel blade manufactured through modern manufacturing processes is subject to limitations in terms of adhesion, sharpness, precision, and cutting ability. These attributes are confounded when working on skin and deeply curved surfaces such as the scalp or face. There is every reason to consider a sapphire blade when other materials have been tried and tested, progressing from obsidian to high-carbon steel to ceramics to sapphire, in order to continue to advance the progression of surgery.

Traditional Steel Blades

Traditional steel blades have been used in surgery for as long as surgical practice has been performed. Steel has the advantage of being tough and not prone to breaking compared to a ceramic cutting blade when used in surgery. Innovative manufacturing techniques have meant that steel cutting edges can be created that hold an edge longer than previous methods used, creating blades that last for up to 2000 rotations, although scratch tests show microscopic chipping and fiber removal as early as 10 rotations. This compares well with the hardest ceramic blades that break at 175 rotations. As a result of this, surgical steel blades have historically been seen as robust and reliable. In hair restoration surgery, this type of blade has served well, facilitating the modern wave of popularity enjoyed by the FUE technique over the traditional strip method. But not all that glitters is steel, and today’s patient and hair surgeon are looking for improvements in surgical technique.

The one great tiny problem with steel, however, is that it doesn’t stay sharp forever. This might be less important in surgery involving the creation of holes for follicular implantation since the blunt end of the hair is resting in ‘dead space’, but when creating slits with a sharp cutting edge, such as in a traditional trichophytic technique strip method, the edge dramatically affects the precise incision created. Some of the disadvantages of a steel blade have an effect on wound healing, such as crush injury from a less sharp blade, affecting aesthetics. But these downsides of steel were not as evident in an FUE-powered device using steel.

Advantages of Sapphire Blades

Sapphire blades in hair transplant have become increasingly popular in a wide range of surgical procedures. These blades offer exceptional sharpness and hardness, which allows for cleaner, smoother incisions. The hardness also means that sapphire blades in hair transplant maintain sharpness far longer than standard steel blades. Other advantages of sapphire material include extreme biocompatibility, which reduces inflammatory responses. The sharpness of sapphire blades in hair transplant allows for efficient engagement with the skin and rapid displacement without hair or tissue damage during the procedure. Tests have shown that sapphire knives are significantly sharper than steel knives in laboratory experiments with standard thin silicone materials, and with everyday use in hair transplantation procedures, sapphire continues to be sharper longer than an ordinary steel knife. When performing surgery with a sapphire knife, incisions are thin and create little damage, have a smoother surface, and need fewer changes. These qualities make sapphire the preferential choice. What is also important is that the results of this technique are appreciated by patients during their check-up appointments as they experience less pain and can go back to work sooner. So, it can be concluded that patients respond better to treatments performed by sapphire blades in hair transplant. The hardness of the sapphire knife is nearly double that of steel, so it maintains its sharpness for a longer period.

Sharpness and Precision

The edge of a sapphire blade is intrinsically sharper than a metal blade and, moreover, is more stable in sharpness over repeated use. A sapphire blade has internal fractures, which create a fine serrated edge that cannot be achieved with any metal. The edges of a steel blade that are created through beveling are inherently fragile; they collapse after they come into contact with an object. In contrast, a sapphire will maintain the sharp edge and not collapse in the same way. One example of the sharpness of a sapphire blade has been noted, as it was observed that it was able to cleanly shave hair from a patient’s neck over an incision with a sapphire blade, and yet blood did not come out from any skin or follicles on the trial operation cut. This edge stability feature explains why companies making consumer products such as knives now market a sapphire knife equipped with a long-lasting razor-sharp blade. The greatest advantage of using sapphire blades in hair transplant is that the quality of incision made still barely changes even when these blades are used for several hours.

Sapphire has distinct advantages in producing cuts with good precision. In hair transplantation, precision in cutting is all about the creation of recipient sites, which are essentially small incisions where hair follicular unit grafts are transplanted. The angle, depth, size, and spacing of these incisions determine what the end results of hair transplantation and surgical aesthetic outcomes will be. The smaller these incisions, the better the quality of the skin that grows in the next year and the more natural the aesthetic results. Indeed, the yield of follicular units does not improve with smaller incisions because the size of the punching blade is important for the survival of the donor graft; rather, aesthetic appearance is the most important factor. Therefore, making smaller recipient sites can give more natural soft results. Sharp incision technology advances hair transplantation further towards minimally invasive surgery while not sacrificing the growth and survival of the transplanted hairs. Aesthetic results are affected by even very subtle scar formation that is produced by making recipient sites. Improved sharpness results in cleaner incision lines. The smoothness of the incision is also important for minimizing the trauma of cutting so that the healing of the incision made can be accelerated. Uneven incision surfaces can block the follicular unit grafts from sliding in at the right angle, leading to improper angle and direction of hair growth. The better smoothness of the incision allows the grafts to be inserted accurately and at the right angle, some of the other significant factors, in addition to incision size, in the appearance of the transplanted hairs. Several investigations have compared the quality of hair transplantation incisions in the recipient or the donor area by comparing the use of sapphire versus making a steel blade. It has been shown that making sapphire blades in hair transplant produces smaller and cleaner incisions than metal blades, even when used with the FUT technique.

Clinical Applications

Hair transplantation is now the most sought-after aesthetic procedure in the field of plastic surgery. Today, cosmetic advances require improving the procedure from both the surgeon’s and the patient’s perspective. Sapphire blades are used in the FUE method. The sapphire blade is a major tool used for the extraction of the FUE technique. The blades are available in various angles and sizes depending on the requirement and are sharpened to a dull round point, usually more rounded than the steel blades. The FUE technique involves two major steps: the creation of the recipient sites and the insertion of the grafts. The first step is important as it depends on the direction, angle, depth, and pattern of the sites prepared in the scalp. The second step is also majorly correlated as it influences the survival of the grafts, thus ensuring a good hair result.

Sapphire blades in hair transplant are used as sharp-tipped scalpels to obtain the grafts of the desired dimensions in the first procedure of the FUE process. With the care of a skin punch, it is ensured that the follicles all the way through the tissue are not harmed, as this moderately increases the effect of the sapphire blade. This happens because of setting up for nares purposely coplanar, which gives rise to the possibility of more quickly collecting intact FUs. Due to the sharpness of the sapphire blade, follicles are easily collected from the tissue. These features minimize trauma and linear scars that can occur during FUE. A sharp, razor-like sapphire blade facilitates precise cutting and achieves a more aesthetic look. As the sapphire blades in hair transplant have a more accurate diameter, they provide a way of better controlling FUE grafts. The diameter of the skin punches during the extraction process largely determines the diameter of the FUE grafts. The sustainability of the FUE devices has an impact on the quality of the grafts. Besides, sapphire tips increase the efficiency of the transplantation with cost-effectiveness.

Hair Transplant Surgery

There has been an increasing focus on sapphire blades and their analogous use in hair transplant surgery. Over time, a number of new blade systems designed to aid in the process of harvesting and receiving hair grafts have been integrated to enhance various aspects of hair restoration. At their inception, the role of these various blade systems primarily focused on creating incisions in the skin, called recipient sites, where hair was to be grafted and aid in the recipient phase of surgery. However, the standardized method for serially harvesting the follicular units remained the same instrument.

With the adaptation of sapphire technology, this paradigm has begun to change. Innovatively sharpened and cut to an extremely fine, dedicated size, sapphire blades have instead been used to fractionally extract hair from the donor site as needed for the FUE method, composed of an incision made with a one millimeter sapphire blade. Several advantages were noted using the sapphire blade. Although initially small by design, sapphire blades were best compared when evaluations included larger sapphire blades. Because sapphires contain a diamond-based surface, they were additionally expected to reduce injuries to the donor site and overall produce a higher yield of donors. Moreover, this in turn limited and improved the aesthetic results of hair restoration. Importantly, graft harvesting using sapphire blades in hair transplant has been used across numerous individuals to attain outstanding hair restoration results. Research determined the newest published findings that confirmed sapphire-based graft harvesting as the optimal method for graft harvesting. These studies were in comparison to others. These depict the beginning use or the proven advancements of sapphire FUE over other means in harnessing the grafts. Generalized data observed from cross-referencing shows that sapphire FUE improved the method of graft harvesting over other conventional means. This portion is supplemented in detail over the subsequent two figures and their captions. The number of article and database searches for sapphire-based FUE graft harvesting methods from 2019 through 2023 has increased.
