Summary

Motorized sharp dissection is the most rapid way to harvest grafts in follicular unit extraction (FUE). The method is utilized around the world with proven results. There are many punch and machine options available to perform sharp motorized dissection. There are a number of patient variables one needs to understand as well as technical approaches one needs to master to ensure the best outcome. These include method of approach, skin and hair characteristics as well as punch size, punch depth, angle, and method of approach, patient positioning, rotation settings, and more. These will vary and need to be adjusted patient to patient. With sharp motorized dissection, it is important to constantly reevaluate the results and modify the approach based on the quality of the grafts. However, if mastered, it can be one of the fastest and most successful methods of FUE harvesting.
