Although necrosis is a rare complication in hair transplantation, it is extremely traumatic for both the patient and surgeon and also has potential medicolegal consequence. Studies have shown that ischemia in the recipient bed is related to tissue damage caused by the instruments used and the number of grafts per cm².
We aimed to measure the effects of different instruments on circulation by dividing the recipient area of hair grafts of the same person into 2 sides as right and left.
Sapphire percutaneous blade was used on the right side, and a handmade razor slit was used on the left side in 12 male patients with consent. Subsequently, vascularity was evaluated with laser Doppler flowmetry.
Scalp vascularity has so far only been evaluated with macroanatomic studies in the literature. First, the authors evaluated the effect of local anesthesia and adrenaline-containing swelling fluids on vascularity with a Laser Doppler Flowmeter. Afterward, the tissue damage caused by sapphire percutaneous blades and handmade blades (obtained from razor blades) were quantitatively analyzed and compared with each other.
Our results showed that handmade razor blades caused significantly less tissue damage.
尽管坏死是植发中罕见的并发症，但它对患者和外科医生来说都是极其创伤性的，并且具有潜在的医学法律后果。研究表明，受区的缺血与器械使用和每平方厘米移植体数量引起的组织损伤有关。
我们旨在通过将同一患者的植发受区分为右侧和左侧来测量不同器械对循环的影响。
在 12 名男性患者同意的情况下，右侧使用蓝宝石经皮刀片，左侧使用手工制作的剃刀切口。随后，使用激光多普勒血流仪评估血管生成。
迄今为止，头皮血管生成仅在文献中进行了宏观解剖研究。首先，作者使用激光多普勒血流仪评估了局部麻醉和含肾上腺素肿胀液对血管生成的影响。此后，定量分析并比较了蓝宝石经皮刀片和手工刀片（从剃刀片获得）造成的组织损伤。
我们的结果表明，手工剃刀刀片造成的组织损伤明显较小。
