[mandibular reconstruction by free bone flaps with micro-anastomosis. Our current indications].

The frequency with which difficulties were encountered in the reconstruction of the continuity of the mandible led us to attempt to systematize our indications. Although grafts, composite pedicle flaps and prosthetic guides still have their appropriate applications. Local conditions are more and more frequently amenable to free flaps. The factors guiding our choice are presented in detail: physical conditions, etiology and anatomy of the defect. In addition, the reason for choosing the type of free flap--iliac crest, fibula or external brachial--is discussed.
