Objective：To summarize adverse reactions and clinical effects of bioabsorbable miniplates in the treatment of maxillofacial fractures. Methods：Clinical data of 43 patients with maxillofacial fracture using biodegradable materials to do rigid internal fixation were reviewed and analyzed. All patients were followed for 3 months to 2 years. Results：Totally 41 patients received good recovery after treatment，with good occlusal relationship. One case of aseptic effusion was observed；the wound was healed after 3 weeks of irri－gating and dressing. Absorbable plate exposure was observed in one case；mucosa tissue was healed after several times of grinding exposed absorbable plate. Conclusion：Bioabsorbable plate is the ideal material in the treatment of maxillofacial fractures.
