research Tissue expansion for the surgical correction of complications caused by hair replacement fiber implants
This case report describes a 45-year-old man with androgenetic alopecia who developed painful abscesses after monacrylic hair fiber implantation, requiring surgical intervention with tissue expansion and flap repair.
research Autologus Hair Transplantation Vs Skin Expansion in Management of Cicatricial Alopecia; A Comparative Study
In this study, both hair transplantation and skin expansion were found effective for treating cicatricial alopecia, with transplantation being preferable for adults with smaller areas and skin expansion suited to younger patients with larger areas.
research Role of tissue expansion in hair restorative surgery
In this study, tissue expansion was identified as a safer initial procedure before hair transplantation for patients with large scalp defects, with the majority of participants having postburn scars and a mean expansion time of 33.6 days.
research Towards expansion of human hair follicle stem cells in vitro
This study demonstrates that human hair follicle stem cells can be cultured and expanded without major changes to their phenotypes, which suggests potential for use in regenerative medicine.
research The Effects of Negative Pressure by External Tissue Expansion Device on Epithelial Cell Proliferation, Neo-Vascularization and Hair Growth in a Porcine Model
