Are Magnetic Resonance Imaging-Generated 3Dimensional Models Comparable to Computed Tomography-Generated 3Dimensional Models for Orbital Fracture Reconstruction? An In-Vitro Volumetric Analysis.

Background: Magnetic resonance imaging (MRI) is being increasingly considered as an alternative for the evaluation and reconstruction of orbital fractures. No previous research has compared the orbital volume of an MRI-imaged, three-dimensional (3D), reconstructed, and virtually restored bony orbit to the gold standard of computed tomography (CT).

Purpose: To measure the orbital volumes generated from MRI-based 3D models of fractured bony orbits with virtually positioned prebent fan plates in situ and compare them to the volumes of CT-based virtually reconstructed orbital models.

Paediatric trauma imaging in a regional Queensland hospital: Do we need clearer guidance?

Objective: Paediatric trauma is a major cause of morbidity and mortality in those aged 0-14. Anatomical and physiological differences require a specialised approach to paediatric trauma care. Medical imaging, particularly computed tomography (CT) scans, requires specific consideration because of the consequences of radiation exposure in the paediatric population.

Investigation of Sustained BMP Delivery in the Prevention of Medication-Related Osteonecrosis of the Jaw (MRONJ) in a Rat Model.

Medication-related osteonecrosis of the jaw (MRONJ) poses an ongoing challenge for clinicians and researchers. Currently, there is a lack of preventative measures available for at-risk patients undergoing tooth extractions, especially those with prior bisphosphonate treatment due to osteoporosis or bone metastasis diagnoses. Here, these issues are addressed using a preventative tissue engineering strategy against MRONJ development.

Systematic review of Australian policing interventions to reduce alcohol-related violence - A maxillofacial perspective.

Alcohol-related violence remains to be a health concern, and the oral and maxillofacial surgeons are routinely exposed to its impact on the victims and the healthcare system. At a community level, various policing interventions have been implemented to address this violent crime in and around licensed premises. Current study sought to examine the effectiveness of these interventions in Australia.

Orbitozygomatic Fracture Repairs: Are Antibiotics Necessary?

Orbitozygomatic fractures are one of the most common maxillofacial injuries encountered. This study aims to investigate and review the management and complications of orbitozygomatic fractures at the Royal Brisbane and Women's Hospital (RBWH). Specifically the postoperative infection rate will be closely examined to determine whether adjunctive antibiotics are necessary in its surgical management.

Bacterial comparison of preoperative rinsing and swabbing for oral surgery using 0.2% chlorhexidine.

Aim: The aim of the present study was to compare bacterial load using preoperative rinsing and swabbing techniques for oral surgery with 0.2% chlorhexidine (CHX).

Methods: Participants were healthy volunteers undergoing a general anesthetic for the removal of teeth.

Management of dental infections by medical practitioners.

Background: Patients with dental infections frequently present to primary care practitioners such as emergency physicians or general practitioners. It is important for these healthcare professionals to understand how to assess and treat such conditions, including when to refer and to whom.

Objective: This article aims to cover basic principles of managing patients with dental infections who present to emergency departments or general practice surgeries.

Magnetic resonance imaging: an accurate, radiation-free, alternative to computed tomography for the primary imaging and three-dimensional reconstruction of the bony orbit.

Purpose: To determine the extent to which the accuracy of magnetic resonance imaging (MRI) based virtual 3-dimensional (3D) models of the intact orbit can approach that of the gold standard, computed tomography (CT) based models. The goal was to determine whether MRI is a viable alternative to CT scans in patients with isolated orbital fractures and penetrating eye injuries, pediatric patients, and patients requiring multiple scans in whom radiation exposure is ideally limited.

Materials And Methods: Patients who presented with unilateral orbital fractures to the Royal Brisbane and Women's Hospital from March 2011 to March 2012 were recruited to participate in this cross-sectional study.

A simplified approach for the reduction of specific closed anterior table frontal sinus fractures.

We describe a simplified approach to the management of closed anterior table fractures of the frontal sinus. Forty-seven patients were diagnosed with this type of fracture during a 3-year period. Of these, 6 had minimally-invasive periosteal raising of the anterior table through a small perieyebrow skin incision, and access to the fracture was through a small trephine or the edge of the fracture itself.

Maxillofacial trauma.

Background: Maxillofacial injuries are a common presentation to general practice and hospital emergency departments in Australia; surprisingly they can be easily overlooked at initial assessment.

Objective: This article describes the common typical clinical and radiographic findings in maxillofacial injuries that require further specialist treatment. Signs and symptoms requiring immediate treatment are highlighted and discussed individually.

Comminuted orbital blowout fracture after vigorous nose blowing that required repair.

A fracture of the orbital floor as a result of nose blowing is rare and we know of only three reported cases. We present a 40-year-old man who required repair of a blowout fracture of the orbital floor as a result of vigorous nose blowing. Patients who present with acute periorbital emphysema after nose blowing require careful assessment with potential blowout fractures in mind.

The patterns of facial injury suffered by patients in road traffic accidents: a case controlled study.

Road traffic accidents cause severe facial injuries and are frequently associated with injuries to other organ systems. The aims of this study were to define the facial injuries suffered by victims of road trauma and assess the need for a multidisciplinary approach to their management. A retrospective study of all patients over 14years of age suffering facial injuries over a five year period was conducted.

Intraocular pressure changes secondary to reduction of orbito-zygomatic complex fractures.

Purpose: To investigate intraocular pressure (IOP) changes in the involved eye during orbito-zygomatic complex fracture reduction, compared with the IOP of the eye on the uninjured side.

Patients And Methods: Twenty patients who presented with displaced, isolated unilateral orbito-zygomatic complex fractures were enrolled. IOPs were measured using a Tono-Pen XL (Medtronic Solan, Jacksonville, FL) in the involved eye and in the non-involved eye.

Emergency department management of maxillofacial trauma.

This paper highlights critical aspects of examination, diagnosis and early management of the maxillofacial trauma patient.

Management of isolated orbital floor blow-out fractures: a survey of Australian and New Zealand oral and maxillofacial surgeons.

Background: This is the first report of involvement of Australian and New Zealand oral and maxillofacial surgeons in the management of isolated orbital floor blow-out fractures and was conducted to obtain comparisons with the results from a recent similar survey of British oral and maxillofacial surgeons.

Methods: A questionnaire survey was sent to all 113 practising members of the Australian and New Zealand Association of Oral and Maxillofacial Surgeons in April 2002 with a second mailout 1 month later.

Results: Sixty-nine per cent of the respondents were referred isolated orbital floor blow-out fractures for management, and just over half of these respondents estimated that 50% or more of the cases went to surgery.

Management of orbitozygomatic fractures.

Background: Management of orbitozygomatic fractures forms part of the scope of practice of many oral and maxillofacial surgeons. As aspects of management vary among surgeons who treat such injuries, this confidential study was undertaken to examine some of the protocols of Australian and New Zealand oral and maxillofacial surgeons.

Results: Eighty-one per cent of the respondents treated orbitozygomaticfractures and on average, each treated approximately 24 cases per year.
