Tissue expansion has undeniable usefulness for providing an alternative source of specialized tissue and even allowing simultaneous closure of donor sites. 
  Recently, tissue expansion became the one of the most popular technique since soft tissue expansion for reconstruction of microtia was attempted by Neumann) in 1957 using an implanted inflatable envelope with an external tube for injections. The use of the tissue expansion technique in head and neck reconstruction was described by Argenta et al. in 1983, and Manders et al. presented three cases of pediatric scalp reconstruction utilizing expansion in 1984.
   In this paper, the authors used 12 tissue expanders to treat 10 alopecia patients with various causes from marich, 1990 to march 1995. All cases were successfully reconstructed without major complication. 
  We have determined that the method is safe, simple, and reliable and provides excellent aesthetic results and high patient acceptance and satisfaction.
  In conclusion, we would like to present that tissue expansion was the most valuable procedure for scalp reconstrucion.
