Area of Science:

  • Hair Restoration Surgery
  • Dermatologic Surgery
  • Regenerative Medicine

Background:

  • Follicular unit excision (FUE) is a primary technique for hair transplantation, utilizing trephine punches to harvest follicular units.
  • The efficacy of FUE is significantly influenced by the characteristics of the trephine punches employed.
  • Numerous innovative punch designs and devices have emerged, presenting a challenge for surgeons in selecting optimal tools.

Purpose of the Study:

  • To conduct a comprehensive review of available punch shapes and devices used in FUE.
  • To provide surgeons with a detailed understanding of the various FUE punch options.
  • To assist hair restoration surgeons in choosing the most suitable punch for individual patient requirements.

Main Methods:

  • Systematic literature search of PubMed database.
  • Reference mining of relevant scientific publications.
  • Hand searching of trade publications for FUE devices.

Main Results:

  • Examination and consolidation of descriptive information for various FUE punches and devices.
  • Creation of textual and visual guides to FUE punch characteristics.
  • Identification that no single punch design is universally optimal; specific uses and limitations exist for each.

Conclusions:

  • Surgeons require comprehensive knowledge of available FUE punch shapes and devices, including their respective advantages and disadvantages.
  • An in-depth understanding of skin properties and follicular unit structure is beneficial for optimizing FUE.
  • Enhanced comprehension of the dynamics of punch excision can significantly improve the FUE technique and patient outcomes.
