Abstract
BACKGROUND: Follicular unit excision (FUE) is used to harvest follicular units for hair transplantation using trephine punches. The characteristics of FUE punches can impact the success of this technique; thus, many innovative punch designs and devices have been developed. With many options available, it can be difficult for the hair restoration surgeon to know which punch best suits the needs of their patients. OBJECTIVE: To provide a comprehensive review of punch shapes and devices available. METHODS: Search of PubMed, reference mining of relevant publications, and hand searching trade publications. RESULTS: We examined FUE punches and devices and consolidated descriptive information for each to create textual and visual guides. No single punch shape or device may suit all cases; thus, it is important to know the best uses and limitations of each. CONCLUSION: The surgeon should have a comprehensive knowledge base of available punch shapes and devices and understand the advantages and disadvantages of each. It is also beneficial to have an in-depth knowledge of skin properties and follicular unit structure. Ultimately, understanding the dynamics behind punch excision will enhance the FUE technique.
