The etiology of fractures of the maxillofacial skeleton varies among studies, with motor vehicle accidents and assaults oftentimes the most common. The number of males outnumbers females throughout most studies. Fractures of the zygoma, orbit, and mandible are usually cited as most common fracture types. This study examines a single center's experience with regards to etiology and distribution of fractures. A retrospective review of all radiologically confirmed facial fractures in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012...

PURPOSE: This study evaluates the accuracy of a statistical shape model (SSM) for virtual fracture reconstruction of the lateral midface. MATERIALS AND METHODS: A uniform bony defect of the right zygoma was created. A virtual reconstruction was performed by using the standard procedure of mirroring the unaffected to the affected side (Group I) and by using the statistical model based on 178 pathologically unaffected CT scans (Group II). The accuracy of the statistical shape model was evaluated in comparison to the present mirroring protocol...

INTRODUCTION: Faciomaxillary fractures (FMF) occur in a significant proportion of trauma patients. Nearly all polytrauma patients and even those with isolated FMF are managed under general anesthesia for definitive management. We propose the use of regional nerve blocks as a safe and effective means for open reduction and fixation of isolated FMF. AIM AND OBJECTIVES: The aim is to evaluate the feasibility, effectiveness and safety of base of skull maxillomandibular and distal trigeminal nerve blocks in the management of FMF...

BACKGROUND: The available referential measures defining the zygomatic bone morphology are adequate enough for full determination of the zygoma positioning, especially for trauma surgery, but osteometric analysis of the zygoma positioning based on tomographic examinations could be useful in peroperative and postoperative imaging. In this study, we propose referential measures, taking into account the morphology and the symmetry of the zygoma. In addition, the reliability and reproducibility are considered...

BACKGROUND: The zygomatic bone constitutes the prominence of the cheek. Fractures of the zygomatic bone are the second most treatment of zygomatic bone fractures and can be examined under two headings, open and closed reductions. This paper describes a new technique in the closed reduction of tripod fractures using a towel clip. METHODS: Seventeen consecutive patients (three females, 14 males) with a mean age of 35.5 years (range = 18-66 years) with zygomatic tripod fracture were treated using the towel clip technique between December 2011 and February 2014...

INTRODUCTION: Because of its functional and cosmetic importance, facial injuries, especially bony fractures are clinically very significant. Missed and maltreated fractures might result in malocclusion and disfigurement of the face, thus making accurate diagnosis of the fracture very essential. In earlier times, conventional radiography along with clinical examination played a major role in diagnosis of maxillofacial fractures. However, it was noted that the overlapping nature of bones and the inability to visualise soft tissue swelling and fracture displacement, especially in face, makes radiography less reliable and useful...

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...

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...

INTRODUCTION: Repair of zygomatic fractures can be classified into the early closed reduction or the more recent open reduction and rigid internal fixation (ORIF) methods. Surgical training and literature advocate ORIF, but the actual frequency of the different techniques in clinical practice is unknown. The purpose of this study was to determine the current trends in the management of zygomatic fractures among US surgeons and elucidate their influences. METHODS: A 10-question survey was developed and distributed to over 16,000 practicing US facial trauma surgeons, including plastic surgeons (PS), oral and maxillofacial surgeons (OMFS), and otorhinolaryngologists (ENT)...

From 2000 to 2010, 720 patients with facial trauma were admitted in Plastic Surgery Service of Argerich Hospital, Buenos Aires, Argentina; 58 of them with panfacial fractures were included in this study. Height velocity impact is the principal etiology, and most concomitant extrafacial injuries are neurocranium and cervical spine. Common affected areas were orbits, nose, and malar-zygoma. The timing of the treatment was airway evaluation, control of bleeding and consciousness, treatment of associated injuries, and finally facial reconstruction...

Saurabh Kumar, S Shubhalaksmi
BACKGROUND: The increasing emphasis on the open reduction and internal fixation of orbito-zygomatico-maxillary complex fractures has led to a more critical appraisal of the various surgical approaches to the orbital and zygomatic skeleton. Transconjunctival approach popularized by Tessier although credited to Bourquet in 1924 offer excellent exposure of the orbito-zygomatico-maxillary complex fracture especially the infra-orbital rim, frontozygomatic suture and the orbital floor. The argument against a transconjunctival access focuses primarily on concern about limited exposure that apparently makes accurate reduction and osteosynthesis of displaced fracture fragments difficult or impossible...

Intracranial tuberculous subdural empyema (ITSE) is extremely rare. To our knowledge, only four cases of microbiologically confirmed ITSE have been reported in the English literature to date. Most cases have arisen in patients with pulmonary tuberculosis regardless of trauma. A 46-year-old man presented to the emergency department after a fall. On arrival, he complained of pain in his head, face, chest and left arm. He was alert and oriented. An initial neurological examination was normal. Radiologic evaluation revealed multiple fractures of his skull, ribs, left scapula and radius...
