Using Angulation of Implanters at 45 Degrees to the Scalp with the Bevel Facing Toward the Skin to Enhance Follicular Entry at Minimal Pressure: A Randomized Clinical Trial in Hair Transplantation

A randomized clinical trial involving 50 male patients with androgenetic alopecia evaluated the effects of using an implanter at a 45-degree angle with the bevel facing the skin during follicular unit extraction (FUE) hair transplantation. The study found that this method significantly reduced insertion resistance, graft popping rate, implantation time, intraoperative bleeding, and improved graft alignment compared to conventional variable-angle implantation. These results suggest that standardizing implanter angulation and bevel orientation can enhance intraoperative efficiency and graft stability, potentially optimizing surgical outcomes in hair transplantation.
