Abstract
Background The open reduction of craniofacial bone fractures requires internal fixation using metal plates and screws, which have been considered the gold standard. However, metal implants pose a risk of palpation, protrusion, and foreign body reaction, and they may require an additional operation for removal. Recently, good results have been reported for absorbable implants which complement the disadvantages of metal implants. This study presents the results of using absorbable mesh, plates, and screws with cyanoacrylate for more accurate and firmer fixation of comminuted fractures of the maxilla. Methods In total, 235 patients underwent operations for comminuted fractures of the maxilla. From January 2012 to December 2014, absorbable mesh and screws were used in 114 patients, while from January 2015 to December 2017, absorbable mesh, plates, and screws with cyanoacrylate were used in 121 patients. Open reduction of the bone fragments was performed, after which absorbable implants were accurately molded and fixed by screws. Results All patients underwent postoperative computed tomography scans, which showed highly accurate reduction and firm fixation in the patients who underwent procedures using absorbable implants, screws, and cyanoacrylate. There were no postoperative complications or cases of abnormal facial contour. Conclusion When absorbable implants and screws are used for maxillary fractures, no additional surgery to remove the metal plate is required. In addition, the use of cyanoacrylate enables accurate and firm fixation of the tiny bone fragments that cannot be fixed with screws.

J Craniomaxillofac Surg 2019; 47:383-388.

Abstract
IMPORTANCE Conventional plating systems include titanium plates for the fixation of facial bone fractures. However, titanium plates result in artifacts on computed tomography images and appear unstable on magnetic resonance images. Therefore, absorbable plates have been widely used for the fixation of facial bone fractures of late in Asia. OBJECTIVE To compare stability and symmetry among four different absorbable plates used for internal fixation of zygomaticomaxillary complex fractures. PARTICIPANTS The subjects were patients with zygomaticomaxillary complex fractures that were diagnosed and treated by internal fixation with absorbable plates between January 2012 and April 2018. Patients aged ≤14 years and ≥76 years were excluded. Patients with other fracture types were also excluded. All patients underwent surgery within 2 weeks of the injury. INTERVENTION Internal fixation was performed with one of four types of absorbable plates, namely Inion®, Polymax®, Osteotrans®, and Biosorb®. MAIN OUTCOME MEASURES The stability of the four plates was investigated by evaluation of the orbital height ratio (A'/A), zygoma angle (a'/a), distance (b'/b) from the midline, and gap (c) of the temporal process on three-dimensional facial computed tomography images obtained before, 3 weeks after, and 3-6 months after surgery. Any plate-associated complications were recorded. RESULTS In total, 400 patients were enrolled, and there were 100 patients in each of the four groups. There were no significant differences with regard to postoperative stability and relapse among the four plates. Moreover, facial symmetry showed no changes over time in any group. Complications such as infection and sensory disturbance were not frequent. All plates except Biosorb® were palpable for more than 6 months after surgery, with Osteotrans® remaining palpable for several years. CONCLUSIONS AND RELEVANCE Our findings suggest that all four types of absorbable plates are useful for treating isolated zygomaticomaxillary complex fractures. While Biosorb® is unsuitable for severe comminuted fractures. Polymax® and Inion® are not bendable at room temperature. It is important to select an appropriate absorbable plate according to each patient's condition and the fracture severity.

Abstract
The purpose of this study was to retrospectively evaluate and examine the incidence of complications using poly-L-lactic acid and polyglycolic acid (PLLA/PGA) copolymer plate system in maxillofacial osteosynthesis. The retrospective study included 87 patients (50 men, 37 women), who needed maxillofacial surgery. We examined the proportion of complications and their factors from clinical data. A comparison was also made for plate decomposition using the molecular weight of the plate without plate exposure and complications. Osteosynthesis sites healed in all patients. Ten cases (11.5%) showed plate exposure-related complications, with all occurring at intraoral surgical sites. There was no significant difference in molecular weight changes of plates in resorbable process. Statistical analysis of study variables between patients with and without exposed plates showed that the plate thickness was significantly associated with the risk of exposed plates (p < 0.05). The commercially available PLLA/PGA device could be a useful rapid resorbable material for maxillofacial osteosynthesis. When thick plates are used on the intraoral site, it may be necessary to pay attention to the complication of plate exposure. Even if exposure-related complications have occurred, resorption and degradation of this material proceeds, suggesting the ease of appropriate risk management.

Abstract
Despite the prevalence of zygomaticomaxillary complex (ZMC) fractures, there is no consensus regarding the best approach to management. The aim of this study is to determine differences in ZMC fracture treatment among various surgical specialties. A survey was conducted regarding treatment of patients with different ZMC fractures that included a minimally displaced fracture (Case 1), a displaced fracture without diplopia (Case 2), a displaced fracture with diplopia (Case 3), and a complex comminuted fracture (Case 4). The survey was distributed to members of plastic surgery, oral maxillofacial surgery, and otolaryngology societies. The rates of surgical treatment, exploration of the orbital floor, and plating three or more buttresses were analyzed among the specialties. A total of 173 surgeons participated (46 plastic and reconstructive surgeons, 25 oral and maxillofacial surgeons, and 102 otolaryngologists). In Case 1, a significantly higher percentage of plastic surgeons recommend an operation (p < 0.01) compared with other specialties. More than 90% of surgeons would perform an operation on Case 2. Plastic surgeons explored the orbital floor (p < 0.01) and also fixated three or more buttresses more frequently (p < 0.01). More than 93% of surgeons would operate on Case 3, with plastic surgeons having the greatest proportion who fixed three or more buttresses (p < 0.01). In Case 4, there was no difference in treatment patterns between specialties. Across the specialties, more fixation was placed by surgeons with fewer years in practice (<10 years). Conclusion There is no consensus on standard treatment of ZMC fractures, as made evident by the survey. Significant variability in fracture type warrants an individualized approach to management. A thorough review on ZMC fracture management is provided.

Abstract
This review discusses and summarizes the recent developments and advances in the use of biodegradable materials for bone repair purposes. The choice between using degradable and non-degradable devices for orthopedic and maxillofacial applications must be carefully weighed. Traditional biodegradable devices for osteosynthesis have been successful in low or mild load bearing applications. However, continuing research and recent developments in the field of material science has resulted in development of biomaterials with improved strength and mechanical properties. For this purpose, biodegradable materials, including polymers, ceramics and magnesium alloys have attracted much attention for osteologic repair and applications. The next generation of biodegradable materials would benefit from recent knowledge gained regarding cell material interactions, with better control of interfacing between the material and the surrounding bone tissue. The next generations of biodegradable materials for bone repair and regeneration applications require better control of interfacing between the material and the surrounding bone tissue. Also, the mechanical properties and degradation/resorption profiles of these materials require further improvement to broaden their use and achieve better clinical results.
