[Rieger's nasal flap. History, technical refinements and indications]

Rieger's flap, described by Rieger as a nasal rotation flap, has often been given other names and descriptions in the literature. We consequently felt an overview of the development, characteristics and technique of Rieger's flap was in order, with the goal of helping surgeons use it to best avail. Rieger's flap is irreplaceable for reconstructing defects of the lower third of the nose located on or near the midline. Variants of Rieger's flap can be used to treat defects located higher up on the nose. Four cases are reported to illustrate these indications.
