Reconstruction of the perineum after tumor surgery.

Major defects of the perineum are often complicated by contracture, radiation injuries, fistulas, and infection. In addition, the perineal surface is unique, and any replacement must meet the requirements of mobility, sensitivity, durability, elasticity, and weight bearing. This combination of complex defects and special surface requirements can be met by adequate extirpative procedures and reconstruction with a number of muscle, musculocutaneous, and fasciocutaneous flap options.
