The use of tissue expanders in head and neck surgery has been popularized since the early 1980s. Tissue expanders are currently used in nasal reconstruction, alopecia, and other head and neck defects when there is inadequate tissue or when transposition of a local flap would create a significant donor-site deformity. Occasionally, situations in head and neck reconstruction arise where local, regional, or free flaps are not available or sufficient for head and neck reconstruction. In these situations, the use of controlled tissue expansion can be employed for enlarging myocutaneous flaps for head and neck reconstructive surgery. Two cases illustrated here present the principles and techniques of this means of reconstruction.

D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.

D015625	Tissue Expansion Devices	Devices used to generate extra soft tissue in vivo to be used in surgical reconstructions. They exert stretching forces on the tissue and thus stimulate new growth and result in TISSUE EXPANSION. They are commonly inflatable reservoirs, usually made of silicone, which are implanted under the tissue and gradually inflated. Other tissue expanders exert stretching forces by attaching to outside of the body, for example, vacuum tissue expanders. Once the tissue has grown, the expander is removed and the expanded tissue is used to cover the area being reconstructed.
