In this study, details of the infraorbital nerve's (ION's) anatomical course variants were compared using computed tomography (CT), and relationships between the variants and fracture patterns in the orbital floor were investigated. Fifty-two normal individuals and 50 patients with unilateral isolated orbital floor fractures were enrolled in this study. Four measurements in normal individuals and five measurements in fracture patients were obtained in parasagittal sections. The anatomical variations of the ION were categorized into three types according to the classification by Ferences et al...

Background: Various surgical methods for repairing medial orbital wall fractures have been introduced. The conventional technique requires total separation of the displaced orbital bones from the orbital soft tissues. However, subperiosteal dissection around the fracture can cause additional damage. The aim of the present study is to introduce a method of reconstructing medial orbital wall fractures without subperiosteal dissection named the "push-out" technique. Methods: Six patients with post-traumatic enophthalmos resulting from an old medial orbital wall fracture and 10 patients with an acute medial orbital wall fracture were included...

A 53-year-old Afghan man presented with a 12-month history of left proptosis, diplopia and facial swelling 20 years after a bomb blast injury. Magnetic resonance and computed tomography imaging revealed a well-circumscribed lesion centred within the left inferior orbit/superior maxillary sinus along with left orbital fracture. Histopathology and immunostaining of the debulked lesion were consistent with traumatic neuroma of the infraorbital nerve. Infraorbital neuromas have developed following orbital decompression surgeries but have not been reported previously following non-surgical trauma...

PURPOSE: Mirroring has been used as a diagnostic tool in orbital wall fractures for many years, but limited research is available proving the assumed symmetry of orbits. The purpose of this study was to evaluate volume and contour differences between orbital cavities in healthy humans. MATERIALS AND METHODS: In this cross-sectional study, the left and right orbital cavities of a consecutive sample of patients' computed tomograms were measured. Inclusion criteria were patients with no sign of orbital or sinus pathology or fracture...

Enophthalmos is caused by an increase of orbital volume after blowout fracture and is one of the most critical complications of such fractures, but is often masked by swelling soon after injury. If surgery is performed after swelling resolves, it becomes more difficult to treat enophthalmos because of atrophy and fibrosis. Accordingly, it is important to estimate the severity of enophthalmos soon after injury. We developed a new criterion for determining whether orbital fractures are indicated for surgery in Asian patients using analysis of orbital volume...

The orbital bones are thin and exposed, making the orbital walls vulnerable to fractures. The floor of the orbit is the weakest portion of this 4-sided pyramid structure. Blunt force trauma is the primary mechanism of injury in young men between the ages of 18 and 30 years. Computerized tomography is the primary imaging technique to diagnose orbital fractures. Conservative versus surgical management is determined by maxillofacial and ophthalmology specialists.

Transconjunctival approach is a standard procedure to address fractures of orbit and the infraorbital rim. Modifications such as transcaruncular or lateral canthal widening allow for extended orbital wall exposure. Especially concerning aesthetics, the transconjunctival approach shows benefits compared to the transcutaneous incisions, such as the transciliary and infraorbital access. Moreover, transconjunctival approach is favored in the literature concerning lid retraction. Monopolar devices have become popular in surgery in the past decades because of good depth control and simultaneous hemostasis with consequently improved overview...

As opposed to the common understanding that diffusion into a cubic-structured single crystal is independent of its crystalline orientation, the diffusion of Li to crystalline Si (c-Si) is anisotropic, which acts as the major cause for the fracture of Si anodes in Li-ion batteries. Here, by conducting comprehensive/multi-scale simulation studies based on molecular dynamics and density functional theory, we elucidate how and why Li diffusion in c-Si is anisotropic. We found that Li ions diffuse to c-Si by following a particular atomic-scale space corresponding to the lowest value of the valence orbital in c-Si, causing Li ions to take a tortuous diffusion pathway...

The Late Pleistocene Shanidar 1 older adult male Neandertal is known for the crushing fracture of his left orbit with a probable reduction in vision, the loss of his right forearm and hand, and evidence of an abnormal gait, as well as probable diffuse idiopathic skeletal hyperostosis. He also exhibits advanced external auditory exostoses in his left auditory meatus and larger ones with complete bridging across the porus in the right meatus (both Grade 3). These growths indicate at least unilateral conductive hearing (CHL) loss, a serious sensory deprivation for a Pleistocene hunter-gatherer...

Gossypiboma and textiloma are terms used to describe tumor-like masses caused by retained gauze or surgical sponges after any operation. It is a rare surgical complication, usually difficult to diagnose due to its variable clinical presentation and nonstandard radiological appearance. We describe here a rare case of orbital gossypiboma in a child after surgical correction of an orbital blowout fracture.

INTRODUCTION: An ectropion is a complication that can arise from reconstruction in the infraorbital region. Often, this complication occurs despite proper positioning of the lower lid at the time of closure. Various transcutaneous approaches to orbit skeleton have investigated in view of complication arising from them. A subtarsal approach with a postoperative Frost suture gives an advantage to reduce the occurrence of ectropion especially after treatment of orbital floor fractures. MATERIAL AND METHODS: This case describes a method of subcuticular suturing technique for subtarsal incision of lower lid which can be used to support the lid during healing period, thus decreasing the rate of ectropion...
