The AO system for primary mandibular reconstruction

Volume-Length Impact of Lateral Jaw Resections on Complication Rates

“…While certain series detailed only external plate exposures, 6 others have noted intraoral exposures only 13 or combined exposures. 3,5,14 Our study suggests that absolute bone loss, and possibly primary resection volume, is the main determinant(s) of platerelated failures using the A-O stainless steel system. The relative impact of soft tissue volume loss on complication rates could have been more strongly stated had volume analysis been carried out by displacement methodology that was not possible in this retrospective study.…”

The faciocervicopectoral flap for non-oncological cases of cheek reconstruction

“…The surgical technique recommended by the AO (Arbeitsgemeinschaft für Osteosynthesefragen) was used for fixation of the bone. 5,6 Resurfacing of the lower face was achieved with the FCP flap. For harvesting the flap, the surgical technique proposed by Soler-Presas et al in 1997…”

A Three Dimensional Analysis of Reconstruction Plates used in Different Mandibular Defects

“…However, under some conditions, metallic plates are preferred, e.g. in case of poor general health of the patient or advanced cancer (9,22). One problem associated with conventional plate systems is the frequent incidence of complications such as screw loosening, plate exposure and plate fractures once masticator function is recovered (7).…”

“…This alloplastic replacement of the mandible may be temporary or definitive (19). Besides the mechanical stabilization, reconstruction plates are also used to avoid dislocation of the mandibular stumps due to scars, which would be a major obstacle to later restoration of mastication (9). the systems employed should ensure both functional/mechanical and morphological rehabilitation (11).…”

“…This results in enlargement of the screw holes which then loosen (8,18). The figures for fractures of the reconstruction plates reported in the literature vary between 2.8% and 9.8% (9,15), indicating that mechanical weakness may be present in the reconstruction system itself. Furthermore, the rates of failure of up to 45% in alloplastic mandibular reconstruction, irrespective of what plate system was used, underscores the potential for improving this kind of reconstruction (8).…”
