PURPOSE: In evaluating patients sustaining bilateral isolated internal orbital fractures, the authors have observed both similar fracture locations and also similar expansion of orbital volumes. In this study, we aim to investigate if there is a propensity for the 2 orbits to fracture in symmetrically similar patterns when sustaining similar trauma. METHODS: A retrospective chart review was performed studying all cases at our institution of bilateral isolated internal orbital fractures involving the medial wall and/or the floor at the time of presentation...

PURPOSE: The authors hypothesized that the risks of optic canal injury in down-fracturing after Le Fort 3 osteotomy vary depending on the separation patterns of the orbital walls. This study verifies this hypothesis using biomechanical simulation. METHODS: Ten finite-element skull models were produced using computer tomography data from ten persons. These models were modified to simulate Le Fort 3 osteotomy models by removing junctions between the neurocranium and facial cranium...

PURPOSE: Detection of optic canal fractures is often difficult because of the subtleness of the fracture. If we could clarify impact on which region around the orbit is likely to accompany the fracture of the optic canal, the knowledge should be useful to make early diagnosis of optic canal fractures. The present study was conducted to elucidate this issue. METHODS: Ten finite element models were produced simulating the skulls of ten humans (8 males and 2 females; 43...

Management of orbital floor fracture remains the most debated topic in maxillofacial field. There are many approaches to reconstruct orbital floor fractures and restore orbital position and function, but many have the drawback of incomplete visualization, especially of the posterior part of the orbit. Pain, diplopia and enophthalmos are the most common presenting symptoms in patients who sustained orbital blow out fracture. The main aim in treating orbital fracture is to reduce the prolapsed orbital tissue and reconstruct the floor which will improve diplopia and enophthalmos...

Orbital fractures are common. In patients where there is significant loss of the medial wall and orbital floor, anatomic prebent 3-dimensional plates allow efficacious restoration of orbital volume. However, the large size of these plates can result in technical difficulties with plate placement, especially in fractures with complete loss of 2 walls of the orbit. In this article, the authors review the pertinent anatomy of the bony orbit with respect to fracture and landmarks in fracture reduction. The authors also note the 3 most commonly encountered problems with the placement of anatomic plates: poor exposure, failure to identify the posterior ledge for the plate, and rotational issues with plate placement resulting in impingement...

Fractures of the frontal sinus are frequently encountered injuries of maxillofacial fractures. The most common causes are traffic accidents, followed by sports-related injuries. There is still no consensus regarding the optimal management of frontal sinus fractures. The authors report a patient with depressed anterior wall fracture of the frontal sinus and superior orbital rim fracture. Reduction was performed by traction from 2 screws applied percutaneously to the depressed fragments and external fixation with an aluminum nasal splint...

A 51-year-old female underwent four upper zygomatic dental implants (ZI) and one upper and four lower conventional implants. Immediately postoperatively, the patient had pain and diplopia upon manual elevation of the edematous eyelid. Panoramic x-ray showed a malpositioned right upper ZI, requiring removal of the right upper ZI the following day. The patient had delayed referral to ophthalmology one month later for persistent diplopia. Computed tomography scan and magnetic resonance imaging demonstrated a right inferolateral fracture with fibrosis surrounding the inferior oblique muscle...

Posttraumatic enophthalmos due to isolated or complex orbital fractures can contribute to diplopia. Current evidence recommends early repair. However, little is known about the outcome of enophthalmos correction when repair occurs beyond 30 days after trauma. In this systematic review, the authors aim to evaluate the current evidence on functional outcomes after delayed repair of posttraumatic enophthalmos.Two independent assessors undertook a systematic review of the literature using multiple databases. The authors' inclusion criteria identified studies involving patients at least 14 years of age who had surgical correction of persistent enophthalmos 30 days after initial trauma...

OBJECTIVE: Advanced three-dimensional (3D) diagnostics and preoperative planning are the first steps in computer-assisted surgery (CAS). They are an integral part of the workflow, and allow the surgeon to adequately assess the fracture and to perform virtual surgery to find the optimal implant position. The goal of this study was to evaluate the accuracy and predictability of 3D diagnostics and preoperative virtual planning without intraoperative navigation in orbital reconstruction. METHODS: In 10 cadaveric heads, 19 complex orbital fractures were created...

INTRODUCTION: Up to 35% of orbital floor fractures extend to the medial wall. This results in restriction of both abduction and adduction, leading to horizontal diplopia. The greater the defect, the more pronounced the enophthalmos. AIM OF THE STUDY: The aim of the study was to determine the influence of concomitant medial wall defects on enophthalmos and diplopia, and the influence of intraoperative revision on the results of surgical reconstruction in patients with orbital floor fracture...

PURPOSE: We conducted a review of orbital fractures treated in our hospital over a period of 4 years. We reviewed several complications of such fractures, especially the relationship of postsurgical diplopia with different presurgical variables: age, gender, type of fracture, fracture area, coronal and sagittal diameter of fracture, fractured floor area, time to surgery, presence of muscle herniation, and presence of muscle entrapment. PATIENTS AND METHODS: Fractures involving the orbital floor remain a controversial issue in terms of surgical treatment and the time from trauma to surgery...

PURPOSE: Reconstruction of orbital wall fractures is demanding and has improved dramatically with the implementation of new technologies. True-to-original accuracy of reconstruction has been deemed essential for good clinical outcome, and reasons for unfavorable clinical outcome have been researched extensively. However, no detailed analysis on the influence of plate position and surface contour on clinical outcome has yet been published. MATERIALS AND METHODS: Data from a previous study were used for an ad-hoc analysis to identify predictors for unfavorable outcome, defined as diplopia or differences in globe height and/or globe projection of >2 mm...

The authors present a rare case of nontraumatic medial orbital wall fracture in an 11-year-old girl. Fractures of the orbital wall secondary to nose blowing have not been previously described in the pediatric population. The patient reported a history of chronic forceful nose blowing, followed by periorbital swelling after an episode of vigorous nose blowing. Erroneous diagnoses of sinusitis and periorbital cellulitis lead to unnecessary antibiotic treatment. The authors hypothesize that repeated and aggressive nose blowing is analogous to stress fractures, leading to weakening and eventual fracture of the medial orbital wall...

PURPOSE: The aim of this study was to observe the surgical outcomes of suture globe fixation to the orbital wall for patients with complicated strabismus. MATERIALS AND METHODS: The medical records of patients with complicated strabismus who were treated at the Zhongshan Ophthalmic Center of Sun Yat-sen University, Guangzhou, China, from January 2010 to June 2015 were retrospectively reviewed. Routine strabismus surgery was not possible in these cases. Eyes were anchored to the orbital wall by simple strong anastomosis of the extraocular muscle and orbital wall tissues using silk suture, which resulted in slight overcorrection of the ultimate ocular position after anchoring...
