We present a case of ophthalmic artery (OA) traumatic avulsion, leading to a post-traumatic subarachnoid hemorrhage (SAH) with ventricular blood invasion and hydrocephalus, mimicking an internal carotid aneurysm rupture. This is the third case of such an event reported in literature and the first without orbital fractures and optic nerve avulsion. Conservative treatment was sufficient for the avulsion, but surgery was needed for the coexisting eye luxation. Traumatic OA avulsion is a rare but possible event and should be suspected in case of basal cisterns SAH, evidence of orbital trauma and CT angiogram or angiographic absence of opacification of the OA...

INTRODUCTION: Yet uncommon, blindness is a potential associated injury of facial fractures. METHODS: Epidemiology, mechanisms, fracture types, and outcome of facial fractures-associated blindness in a 10-year period are retrospectively reviewed. RESULTS: Out of 907 facial fractures patients, 10 had blindness, giving a frequency of 1.1%. There were 9 men and 1 woman whom age range was 6 to 59 years (mean: 31.2 years). Intentional injury patients were significantly the most at risk of blindness (P = 0...

Transconjunctival approach has become a standard procedure to access fractures of orbit and the infraorbital rim. The transconjunctival incision can be performed pre- or retroseptally. Both approaches have been described combined with modifications such as transcaruncular or detachment of the lateral canthus for wider exposure of the orbital walls and rim. Particularly concerning aesthetics, the transconjunctival approach shows advantages compared to the transcutaneous incisions, such as the transciliary and infraorbital access...

BACKGROUND: Platelet-rich fibrin (PRF) has been applied in the clinical field for more than a decade, but largely in oral surgery and implant dentistry. Its utilization in plastic and reconstructive surgery is limited and lacking a comprehensive review. Hence, this article focuses on the various clinical applications of PRF pertaining to the plastic and reconstructive field through a systematic review. METHODS: In this review, articles describing the clinical application of PRF in plastic and reconstructive surgery were screened using predetermined inclusion and exclusion criteria...

Background: Lower eyelid incisions are widely used for the orbital approach in periorbital trauma and aesthetic surgery. In general, the subciliary approach is known to cause disposition of the lower eyelid by scarring the anterior lamella in some cases. On the other hand, many surgeons believe that a transconjunctival approach usually does not result in such complications and is a reliable method. We measured positional changes in the lower eyelid in blowout fracture repair since entropion is one of the most serious complications of the transconjunctival orbital approach...

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...

OBJECTIVES: Both traumatic orbital apex syndrome (OAS) and traumatic superior orbital fissure syndrome (SFOS) are rare conditions after craniofacial injury. Few types of researches investigate the difference in clinical characteristics and outcome between them. We describe clinical features and cranial nerves functional recovery of traumatic OAS or SOFS and to discuss surgical decompression of these patients. PATIENTS AND METHODS: A retrospective study was performed of 15 patients diagnosed with traumatic OAS and 39 patients with traumatic SOFS from July 2010 to July 2017 in our hospital...
