Light and Electron Microscopic Analysis of Controlled Injury to Follicular Unit Grafts
Overview
Affiliations
Background: Careful manipulation of hair units is essential for a good yield of transplanted hair.
Objective: To analyze the morphology of dissected follicular units submitted to crushing, stretching, bending, and drying.
Methods: Follicular units were either crushed, bent, stretched with forceps, or left drying on surgical gloves for 3 minutes. The specimens were fixed and prepared for observation with light microscopy or transmission and scanning electron microscopy.
Results: No alterations were detected in follicular units that had been crushed, bent, or stretched. Major damage occurred in samples that were left to dry on gloves.
Conclusion: Letting the follicular unit dry appears to be the worst mishandling to which the follicular units may be subjected during routine hair transplantation.
