This article report 5 cases of malunion or nonunion ofthe fractures of the jaws which were treated by functional re-duction. From the anatomical and physiological point ofview, this operation was highly versatile and reliable. The re-construction was accomplished precisely in one stage. All pa-tients had a good prognosis.
The three-dimensional (3-D) Titanium miniplate system is one of the newest internal rigid fixation for the maxillo-mandibular surgery in recent years. The geometry of the plate assures a good stability in the three-dimensions of the fracture sits. Thirty patients suffering from maxillo-mandibular fractures had been operated on using the 3-D Titanium miniplates since 1991. The group of the patient included 16 cases of mandibular fractures, 8 cases of maxillary fractures and 6 cases of maxillo-mandibular fracture. All of the patient had very good result without any complication. The follow-up was 6 months to 3 years. The 3-D Titanium miniplate as an ideal easy to use, good resistance against torque forces and, compact forms of the miniplate were the some of the advantages. Clinical examples had been provided to illustrate the actual usage of the 3-D miniplate in the field of the surgical treatment for the maxillo-mandibular fracture. It is the author’s opinion that the internal rigid fixation by 3-D Titanium miniplates is a promising method of treating fractures of the maxilla and is to be better tolerated by the patients and surgeons.
Objective To systematically review the efficacy of poly-L-lactide (PLLA) material treatment versus titanium plates treatment for mandibular fractures. Methods We searched the Cochrane Library, PubMed, Embase, Chinese Journal Full-text Database, VIP Database, and Wanfang Database to collect literatures about randomized or non-randomized controlled trials using PLLA treatment (the trial group) versus titanium plates treatment (the control group) for mandibular fractures in the last ten years (from January 2007 to March 2017). The quality evaluation and data extraction were carried out by 2 reviewers independently and analyzed by Review Manager 5.3 software. Results A total of 8 literatures including 453 patients with mandibular fractures were included in this Meta-analysis. There was no significant difference in total complications between the two groups [odds ratio (OR)=0.98, 95% confidence interval (CI) (0.55, 1.75), P=0.95], including dislocation healing [OR= 0.96, 95%CI (0.46, 2.01), P=0.90], occlusal disturbance [OR=1.53, 95%CI (0.61, 3.87), P=0.37], infection [OR=0.63, 95%CI (0.23, 1.74), P=0.37], and secondary operation [OR=0.46, 95%CI (0.17, 1.27), P=0.14]. Conclusion There is no significant difference between PLLA and titanium plate in the treatment of mandibular fractures.
