OBJECTIVES: Head and face injuries are leading causes of emergency department visits in children. There is yet no clinical decision rule on face CT such as pediatric head CT rules. The goal was to develop and validate a clinical decision rule for identifying orbital wall fractures in children with periorbital trauma in the emergency department. METHODS: This was a retrospective derivation and validation study. Children younger than 18 years who underwent orbit CT after periorbital trauma were included between January 2011 and December 2013 in 3 emergency centers...

BACKGROUND: A case of orbital emphysema associated with elevated intraorbital pressure, presenting as a complication of a paranasal sinus "blow-out" fracture after trauma to the orbit and globe is presented. CASE REPORT: A 45-year-old man developed left globe rupture with orbital emphysema after blunt trauma. A large air pocket in the superior orbit with medial wall fracture and globe tenting was identified on noncontrast computed tomography. Direct needle drainage was performed using a 23-gauge needle attached to a saline-filled syringe with the plunger removed...

Craniomaxillofacial trauma management has continued to improve and evolve as a result of advances in technology and scientific inquiry. Controversies exist where there is little evidence-based literature to guide treatment in frontal sinus management, rigid versus absorbable fixation, open versus closed treatment of mandibular condyle fractures, extraction of teeth in the line of fracture, optimal timing for repair of mandible fractures, antibiotic use for facial wounds and fractures, and reconstructive materials in orbital fracture reconstruction...

PURPOSE: Posttraumatic edema in facial bone fracture patients may interfere with the operation field and delay the schedule. Thus, swiftly reducing the edema alleviates patient discomfort and advances the operation date. Ice packing and compression bandages are often used for such a purpose, but such methods are often inconvenient for the face. In this study, we aim to analyze the effect of light-emitting diode (LED) (590/830 nm)-based low-level laser therapy (LLLT) in posttraumatic edema in facial bone fracture patients...

BACKGROUND AND AIM: The otolaryngologist often meets with fractures of the orbital floor. The most serious complication is diplopia, arising as a result of herniation of the orbital contents, with or without fixation of the inferior rectus muscle. The aim of our work was to create a mathematical model to calculate the volume of prolapsed soft tissue of the orbit in blow-out fractures, as a factor in deciding on the need for surgical treatment. PATIENTS AND METHODS: In a retrospective study (2007-2013), we evaluated 80 patients with blow-out fractures, divided into two equal groups: 40 conservatively treated and 40 surgically treated patients...

BACKGROUND: Sequelae of inadequate orbital reconstruction include enophthalmos, hypoglobus, and diplopia. Accuracy of orbital reconstruction is largely subjective and especially difficult to achieve because of anatomic distortion in secondary or late reconstruction and in extensive injury. We combined computer navigation and endoscopy to perform accurate, aesthetic, and safe minimal-access primary and secondary orbital reconstruction. METHODS: From 2013 to 2014, 24 patients underwent unilateral primary and secondary or late minimally invasive orbital reconstruction with mainly Medpor and/or titanium mesh by navigation and endoscopic assistance through transantral, transconjunctival, or upper blepharoplasty approaches...

Orbital floor fractures can produce acute constitutional symptoms and poor ocular outcomes. This study aims to determine the clinical and radiological predictors of tissue entrapment in pediatric orbital floor fractures and to explore the effect of operative timing on ocular outcomes. The authors reviewed medical records from pediatric patients with orbital floor fractures from 2007 to 2015. One hundred fifty-two patients with 159 orbital floor fractures were included. One hundred twenty-two (80.3%) patients were male, and the mean age was 12...

BACKGROUND: Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration...

Orbital reconstruction is one of the most challenging tasks for surgeons who treat craniofacial trauma. Suboptimal outcomes carry a high level of morbidity, with functional, emotional, and aesthetic implications. However, advances in reconstruction techniques, including the use of orbital endoscopy, computer-guided navigation, and mirror image overlay techniques, have been shown to provide significant improvements in outcomes. This article provides practical advice for applying these techniques to orbital reconstruction following trauma...

Hip resurfacing offers advantages for young active patients afflicted with hip osteoarthritis, and may also be a beneficial treatment for adult canines. Conventional hip resurfacing uses metal-on-metal bearings to preserve bone stock, but it may be feasible to use metal-on-polyethylene bearings to reduce metal wear debris, while still preserving bone. This study characterized the short-term wear behavior of a novel hip resurfacing implant for canines that uses a 1.5 mm thick liner of highly cross-linked polyethylene in the acetabular component...

The treatment has been improved on the accurate reduction of blow-out fracture for many decades. But still, it has been limited to reduce completely when surgeons are approaching by conventional technique. The authors analyzed the postoperative results using computed tomography (CT) scans after conventional open reduction of isolated medial wall fracture. Thirty-seven patients with isolated medial wall fracture were reviewed. All patients underwent preoperative, immediate, and postoperative CT scans. Two surgeons have performed the surgery by conventional open reduction with transcaruncular approach and absorbable mesh insertion...

Backgroung and Aim. This work builds on our publication on the subject of creating a mathematical model for calculating the volume of proplaped soft tissue of the orbit in blow-out fractures, which aids us greatly in our choice of the most effective treatment immediately post-accident. PATIENTS AND METHODS: In this prospective study (2014 - 2016) we treated 29 patients with blow-out fractures. 18 (62%) were treated conservatively and in 11 (38%) we proceeded surgically. We decided whether surgical or non-surgical therapy was appropriate on the basis of clinical ENT, eye examination and the total volume of prolapsed orbital soft tissue...

INTRODUCTION: Development of a posttraumatic herniation of brain parenchyma through the orbit is a rare complication of orbital roof fracture. Mostly, the injury is due to a direct impact to the frontal region resulting in orbital roof fracture with dural defect and herniation of cerebrospinal fluid or brain parenchyma. These patients present with acute or gradually progressive proptosis with impending risk of loss of vision and mandate surgical decompression of optic nerve with watertight closure of the dural defect...

PURPOSE: The management of orbital blowout fractures (BOFs) is controversial: the evaluation of diplopia is the most important criterion for planning whether to undertake surgery. Our aim was to determine CT findings that may suggest the presence of diplopia when patients with BOFs cannot be adequately examined to plan an orbital repair. METHOD AND MATERIALS: We retrospectively evaluated CT of all patients presented to our Emergency Department for blunt craniofacial trauma (N = 3334) from January 2014 to March 2016, selecting patients with CT-demonstrated BOFs...

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 years earlier. A 50-year-old man was admitted to the emergency room for an exposed substance in the lower eyelid area of the left eye, which began as a palpable hard nodule a week earlier...
