Shield-shaped preoperative design in the clinical application of androgenetic alopecia in men
Objective To assess the effectiveness and safety of follicular unit extraction(FUE)with shield-shaped preoperative design in treating advanced androgenetic alopecia in men.Methods Sixty-one male patients with Norwood-Hamilton grades V-VI an-drogenetic alopecia were treated with FUE involving shield-shaped preoperative planning.Observations included general patient condi-tions,surgical details,naturalness of hair,patient satisfaction,and adverse reactions.Results The 61 patients had an average of(3799±444)FUs transplanted,with a single graft density of 60 FUs/cm2,and a multi-graft density of 30～50 FUs/cm2.The average duration of surgery was(9.5±1.0)h.Patients rated the naturalness of their hair at 4.90 on the Likert scale and their satisfaction at 4.74.Doctors rated the naturalness of their hair at 4.87 on the Likert scale and their satisfaction at 4.82.All patients were followed up for 6 to 12 months,no severe side effects were observed.Conclusion The use of the shield pre-designed FUE technique for treating extensive androgenetic alopecia in males results in transplanted hair that appears relatively natural in density and appearance.The technique is associated with high patient satisfaction and few postoperative complications,making it worthy of clinical application and promotion.
