The intraoral region include structures that represent a functional matrix for the physiology of this region. The reconstructive problems of this area are centred around difficulties to obtain thin flaps that provide coverage without excessive bulk and uninhibited tongue motion. For this regions the radial forearm flap is particularly suited to intraoral reconstruction because it is thin, minimally hair bearing and with moderate donor site morbidity. The Authors report their experience in 6 cases of intraoral reconstruction with radial forearm flap and analyzes it's surgical, anatomical and anatomopathological features. The advantage, the svantage and the indications of this flap are discussed.
