Theoretical basis and clinical practice for FUE megasession hair transplantation in the treatment of large area androgenic alopecia

摘要

Background Large area androgenic alopecia patients seeking hair transplantation treatment has become common. FUE Megasession has become a choice for more and more people. Long-term in vitro preservation of hair follicles during FUE Megasession has become a new challenge. @@@ Objective To explore optimal in vitro preservation condition according to FUE Megasession long-period surgery time and to perform clinical practice to confirm the feasibility. @@@ Methods Human follicles were obtained from informed patients by FUE Megasession and preserved under different conditions. Live and dead staining with DAPI was used to assess the survival rate of cells. Hair follicles were preserved in vitro for 7 days under different conditions, and the extension of the hair shaft was observed. We also performed some clinical procedures to illustrate the effectiveness of these methods. @@@ Results Under the condition of 4celcius Ringer's solution, the death rate of hair follicle cells was lower than that of the rest. 4celcius Ringer's solution supported superior growth of the hair follicle unit according to organ culture. 8-h preservation in 4celcius Ringer's solution was kept as high survival rate as the traditional hair transplantation surgery(P > .05?. Clinical procedures confirmed the feasibility of FUE Megasession hair transplantation surgery. @@@ Conclusion 4celcius Ringer's solution in vitro preservation is optimal for clinical FUE Megasession surgery which ensures the hair follicle survival rate and postoperative results.
