PURPOSE: To study whether ethmoidectomy predisposes the orbit to medial wall fracture with lesser trauma. METHODS: An interventional cadaver study of 5 heads (10 orbits); the left or right orbit was randomized to undergo endoscopic complete ethmoidectomy with the fellow orbit as control. Fractures were induced with direct globe trauma, and heads underwent CT scanning. Energy to induce fracture, peak orbital pressure at time of fracture, fracture pattern, and volume of herniated tissue were measured and analyzed...

INTRODUCTION: The evolution of medical practice is resulting in increasing subspecialisation, with head, face and neck (HFN) trauma in a civilian environment usually managed by a combination of surgical specialties working as a team. However, the full combination of HFN specialties commonly available in the NHS may not be available in future UK military-led operations, necessitating the identification of a group of skill sets that could be delivered by one or more deployed surgeons. METHOD: A systematic review was undertaken to identify those surgical procedures performed to treat acute military head, face, neck and eye trauma...

Facial fractures often result in changes of the orbital volume. These changes can be measured in three-dimensional (3D) computed tomography (CT) scans for preoperative planning and postoperative evaluation. The aim of this study was to analyze the orbital volume and shape before and after surgical treatment of unilateral orbital fractures using semi-automatic image segmentation and registration techniques. The orbital volume in 21 patients was assessed by a semi-automatic model-based segmentation method. The fractured orbit was compared relative to the contralateral orbit...

The advent of titanium hardware, which provides firm three-dimensional positional control, and the exquisite bone detail afforded by multidetector computed tomography (CT) have spurred the evolution of subunit-specific midfacial fracture management principles. The structural, diagnostic, and therapeutic complexity of the individual midfacial subunits, including the nose, the naso-orbito-ethmoidal region, the internal orbits, the zygomaticomaxillary complex, and the maxillary occlusion-bearing segment, are not adequately reflected in the Le Fort classification system, which provides only a general framework and has become less relevant in contemporary practice...

BACKGROUND: Patients who present for a trauma workup often have a head computed tomography (CT) performed to identify intracranial pathology. Facial fractures are routinely identified in these patients, and further imaging is the norm with dedicated facial CT scans. Additional imaging increases radiation doses; however, it is unclear if additional operative fractures are identified. The aim of this study was to examine differences between these 2 CT imaging modalities. METHODS: A retrospective review of all operative facial trauma patients receiving both head and facial scans at a single institution was performed (1999-2012)...

Siwei Zhou, Katherine Duncan, S Tonya Stefko
Silent sinus syndrome was first described as spontaneous enophthalmos and hypoglobus associated with subclinical maxillary sinusitis without prior trauma or surgery. This clinical entity has later been described after trauma in which damage to the ostiomeatal complex leads to atelectasis of the maxillary sinus. We report a case of a 14-year-old boy who presented 4 years after sustaining a non-operative orbital floor fracture with enophthalmos and transient diplopia. Computed tomography (CT) demonstrated enlargement in size of the original orbital floor fracture and bilateral maxillary sinus disease...

PURPOSE: Diplopia is a common symptom of blowout fracture (BOF), and can persist after proper surgical management. We compared clinicoradiological findings between patients with recovering diplopia and those with residual diplopia after surgery for orbital BOF. MATERIALS AND METHODS: We retrospectively evaluated the CT images of 170 patients with orbital BOF and preoperative diplopia. We reviewed the following factors: sex, age, mechanism of injury, presence of diplopia before surgery, presence of enophthalmos before surgery, presence of an ocular motility abnormality before surgery, time interval between the trauma and surgery, fracture type, fracture size, volume of herniated orbital soft tissue, ratio of the volume of herniated orbital soft tissue to fracture size, number of points of contact between the extraocular muscle (EOM) and bony edge, EOM swelling, EOM swelling ratio, EOM displacement, EOM circling, EOM tenting, and EOM entrapment...

PURPOSE: The use of technology to aid in assessment, planning, and management of complex craniomaxillofacial injuries is increasingly common. Preoperative computed tomography (CT) evaluation is considered the standard of care, and intraoperative imaging is becoming increasingly accessible. Limited data exist regarding the implication of intraoperative CT on decision making in the management of all sites of facial fractures. The purposes of this study were to characterize the use of an intraoperative CT scanner for craniomaxillofacial surgery within our institution, to quantify the effect of intraoperative CT on surgical decision making, and to attempt to provide guidance on when to use this technology...

Complete extraocular muscle transection is uncommon in the setting of blunt trauma. We report a case of a 53-year-old male that developed diplopia after hitting his face directly on a concrete slab after a fall. On examination, he had a right hypertropia with a complete infraduction deficit. A CT scan of the face showed an orbital floor blowout fracture with complete inferior rectus transection. On surgical exploration, the distal and proximal ends of the muscle were identified and sutured together, and the floor fracture was repaired...

A 16-year-old boy presented with progressive left hemidystonia over 3 years. The possibilities of symptomatic hemidystonia due to focal lesions such as infarct (vasculitis), tumours, tuberculoma, arteriovenous malformations or heredodegenerative disorders such as Wilson disease were considered. Imaging showed a peculiar scar involving right basifrontal region extending upto anterior, centromedian and dorsomedial nuclei of thalamus due to blowout fracture of roof of orbit. This scar was responsible for progressive left hemidystonia...

Background: Orbital fractures are classified as diseases usually related to common midface trauma. It represents the most challenging treatment due to the complex anatomy, physiology, and aesthetic role. A midface trauma involves also the zygomatic complex and the nose, however the orbit fracture seems to be a more frequent disease due to its anatomical features. Objective: The purpose of this work is to retrospectively evaluate and record the frequency of the midfacial traumas and orbital fractures observed in the North Eastern Sicily...
