INTRODUCTION: In recent years, bioresorbable plates have undergone remarkable development. However, there has been no attendant improvement in their strength, because strength requires thickness, and complications such as palpability are related to the thickness of bioresorbable plate systems. In this clinical study, we compared the surgical management of zygomatic fractures using newly developed thinner bioresorbable materials or conventional titanium miniplates. METHODS: Twelve patients with zygomatic fractures were randomly divided equally into 2 groups (6 with new bioresorbable osteosynthesis materials and 6 with standard titanium miniplates)...

Ballistic injuries of oral and maxillofacial region are usually fatal due to close propinquity with the vital structures. The severity of injury depends on the caliber of the weapon used and distance from which the patient is shot. The preliminary care of facial ballistic wounds strictly adheres to the basics of trauma resuscitation. Early and appropriate surgical management has proved to be influential on the final outcome and esthetic result. Treatment of facial gunshot wounds should be planned and carried out carefully to avoid esthetic complications...

Fractures of the zygoma are relatively frequent and their management has been extensively described. Above all, isolated zygomatic arch fractures comprise about 10% of all zygomatic fractures. Temporal approach is common surgical method, Gillies approach, but it has the limitation of blinded surgical approach. So, the mobile intraoperative fluoroscan is used famously for more suitable reduction, but it needs an additional man to control the machine and increases irradiation doses. The authors got the simple idea, but so helpful tool, and it has been performed since 2012...

Zygomatico-maxillary complex fractures present a challenging diagnostic and reconstructive task to the surgeon. Gillie's temporal approach has been a commonly used technique for zygomatic arch reduction but surgeons have been commonly using a buccal sulcus approach for the reduction of zygomatic arch fractures as well as for combined zygomatico-maxillary complex fractures. This paper outlines the use of Rowe's elevator (modification of Bristow's elevator) intra-orally to reduce zygomatic arch fractures and if required, simultaneously plate the zygoma through the same approach...

OBJECTIVE: To analyze the impact of maxillofacial injury on skull base. METHODS: A three-dimensional(3D)finite-element model of cranio-maxillofacial bone was established by CT scan data. A lead cylinder in base diameter of 3 cm was designed as an impactor. There regions(upper right maxilla, left infraorbital margin and left zygomatic body)subjected to an impact at the speed of 8.6 m/s(about 30 km/h)was simulated. Thirteen landmarks at the skull base were selected...

Surgical navigation systems have been an important tool in maxillofacial surgery, helping surgeons create a presurgical plan, locate lesions, and provide guidance. For secondary facial bone reductions, a good presurgical plan and proper execution are the key to success. Previous studies used predetermined markers and screw holes as navigation references; however, unexpected situations may occur, making the predetermined surgical plan unreliable. Instead of determining positions preoperatively, this study proposes a method that surgeons can use intraoperatively to choose surface markers in a more flexible manner...
