Tissue Expanders in Maxillofacial Surgery

Tissue expansion is soft tissue reconstruction, the main principle is to develop the donor tissue by expansion next to the defect. Such donor flaps are twice as large. After dividing the expanded flap for reconstruction, the donor site is well preserved, but the defect is reconstructed with adjacent tissue of similar texture, color, thickness, and sensation. Has minimal scarring. Tissue enlargement is the future of dentistry because it helps patients cover enough tissue, give the defect area excellent aesthetics, and minimize hospital visits and discomfort. Intraoral clinical applications of tissue expanders require extensive knowledge of tissue regeneration. A good surgeon can increase tissue surface area through mechanical creep and biological stretching. This is used to reshape the defect. It improves soft tissue quality and quantity, promotes primary wound closure, and reduces the incidence of wound dehiscence and bone graft exposure. The only thing the surgeon should keep in mind is correct placement of the expander and control of the expansion rate.
