COMPARISON OF MINIPLATES AND RECONSTRUCTION PLATES IN MANDIBULAR RECONSTRUCTION

Abstract: Background. The aim of this study was to compare complication rates of miniplates versus reconstruction plates in the fixation of vascularized grafts into segmental mandibu-lar defects. Methods. Retrospective analysis of 143 consecutive suc-cessful microvascular composite flaps performed between 1993 and 2001 was performed. Data were gathered from a compu-terized database, case notes, and pathology reports. Complica-tions were classified as dehiscence, infection, and plate or bone removal. Results. In the series, 49 % of patients received miniplates, and 51 % received reconstruction plates. No significant differ-ences in complication rates were found between those grafts fixed with miniplates (27%) and those with reconstruction plates (30%). Plate choice was determined primarily by consultant preference. No significant differences were found in patient, defect, treatment, or follow-up characteristics between the plate groups. Twenty-nine percent of patients had at least one late complication at the reconstructed site, and this was higher (39%) in those who had postoperative radiotherapy. Conclusions. No evidence was found in this study that the increased rigidity offered by reconstruction plates influences the rate of plate or bone removal, infection, or plate exposure. Thus, the decision to use reconstruction or miniplates is not dependent on the rate of plate complications. B 2003 Wiley Periodicals, Inc
