Feily’s Method as a New Mode of Hair Grafting in Prevention of Scalp Necrosis Even in Dense Hair Transplantation

Eight years ago, a study introduced Feily's method, a new technique in hair grafting that could prevent scalp necrosis, even in dense hair transplantation. The method used a special needle to create recipient sites, improving blood supply and oxygenation, and reducing the risk of scalp necrosis. The study identified a "danger zone" on the scalp, particularly the central region and the right parietal aspect, that was most vulnerable to necrosis. This was based on an analysis of 18 pictures from Iranian hair transplant centers. A case series with 16 patients found that dark areas on the scalp after slitting could be a predisposing factor for scalp necrosis. The researchers proposed that graft insertion should ideally occur 24 hours after dense slitting, allowing for a reperfusion time that could decrease the risk of necrosis. This method was applied to the 16 patients, and no evidence of necrosis was found. The study concluded that adequate reperfusion time is crucial to prevent necrosis in hair transplantation procedures.
