Follicular Unit Excision (FUE) Motorized Blunt Punch Follicular Unit Extraction

The development of motorized follicular unit extraction (FUE) machines with blunt punches significantly advanced the FUE technique in hair restoration due to their lower transection rates during graft harvesting. The blunt punch technique involved separating tissue with blunt shearing force rather than cutting, allowing for deeper punch advancement without risking follicle transection. This method provided precise tactile feedback, reducing transection and capping rates. However, challenges included graft burying and difficulty with body hair excision, which were mitigated by evolving the blunt punch to a flat punch with a corner. The blunt punch technique was also easier for beginners to learn compared to the sharp punch technique.
