BACKGROUND AND OBJECTIVES The orbital floor may fracture alone, and the fracture is then defined as "pure"; when there is a rim involvement, the fracture may be defined as "impure". Controversy exists as to the pathophysiology of orbital floor fractures and the incidence of orbital rim involvement. The purpose of this retrospective review was to determine the incidence of purity in orbital floo...

Purpose. To determine factors associated with the presence of significant ocular injury in subjects with orbital fractures. Subjects. A consecutive prospective cohort of 161 patients presenting to a general tertiary referral hospital with orbital fractures and undergoing initial conservative treatment was identified. Subjects were assessed at time of injury for the need for emergency surgery, a...

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 year...

PURPOSE Blowout fracture characterized by concurrent floor and medial wall fractures is a rare entity. We compared surgical outcomes between a single approach and a double approach in patients with orbital fracture by measuring the postoperative orbital volume. METHODS We confirmed that 21 (8.5%) of a total of 246 patients with orbital fractures had fractures of the medial wall and floor thro...

A prefabricated, sculptured, subperiosteal orbital floor implant was used in six cases of cosmetically unacceptable deep superior eyelid sulcus that occurred after enucleation. The implant provided anterior and superior displacement of orbital contents. Surgical placement was similar to the approach for implant placement in orbital floor fracture and provided satisfactory cosmetic and functiona...

This study was performed to evaluate the clinical symptom, fracture finding, and surgical outcome in children with orbital trapdoor fracture. Forty-four patients with pure orbital trapdoor fracture, under 18 yr of age, were included. Time interval between injury and surgery, length of time for improvement, resolution of ocular motility restriction, and other factors were analyzed in 36 patients...

Orbital emphysema is usually a benign, self-limited condition. Intraorbital extension of the entrapped air in the absence of an orbital fracture is extremely rare. Although benign, a careful periodic monitoring of intraocular pressure, optic nerve examinations, and prompt management are warranted in order to prevent tension pneumoobitus secondary to increasing intraorbital pressure by the orbit...

Purpose To report a case of lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to the orbital roof. Observations A 23-year-old female was presented with right lagophthalmos. Five months prior to consult at our clinic, she suffered from a penetrating trauma to the frontal lobe of the brain through the right orbital roof with cerebrospinal fluid leakage. Decompressive cranie...

BACKGROUND A blow-out fracture is one of the most common facial injuries in midface trauma. Orbital wall reconstruction is extremely important because it can cause various functional and aesthetic sequelae. Although many materials are available, there are no uniformly accepted guidelines regarding material selection for orbital wall reconstruction. METHODS From January 2007 to August 2012, a ...
