OBJECTIVES: Endoscopic approach provides excellent magnification and visualization, and a purely transnasal approach is minimally invasive method. However, it is very difficult to repair anterior and lateral fractures with the previous transnasal endoscopic approaches, since repair of orbital fractures is managed through the middle meatus and ostium from the posterior side of the nasolacrimal duct with side-viewing endoscope and curved instruments. Therefore, the authors used modified transnasal endoscopic approach as an alternative for repair of orbital floor fractures in order to effectively reach the lateral or anterior fracture of the orbital floor with straight endoscope and instruments endoscopically...

A 25-year-old man suffered an isolated lens anterior capsular tear and mature cataract formation following blunt injury to his right eye. One week after the trauma, best-corrected visual acuity (BCVA) in the right eye was hand motion. B-scan ultrasonography showed that the lens posterior capsule was intact; no vitreous foreign body or retinal pathology were observed. Orbital computed tomography revealed narrowed anterior chamber and increased lens material volume and lens reflectivity in the injured right eye...

BACKGROUND: Restoration of orbital volume after internal orbital fractures can prevent enophthalmos. A variety of allografts are commonly used including titanium mesh with and without porous polyethylene coating. Some controversy exists over the use of uncoated titanium mesh in the orbit. Newer products contoured to the three dimensional orbital anatomy aim to improve reestablishment of the complex orbital shape though studies of outcomes with their use are limited. METHODS: A retrospective chart review was performed to evaluate surgical outcomes in all patients who underwent orbital fracture repair with DePuy/Synthes titanium MatrixMIDFACE prefabricated implants (PFTi) as compared with porous polyethylene/titanium hybrid implants (PPETi) including Stryker Medpor Titan, MTB, and BTB implants...

BACKGROUND: Posttraumatic enophthalmos is a relatively common problem following orbitozygomatic fractures. However, inadequate long-term results are frequently observed due to the difficulty of performing intraoperative fine adjustments to soft-tissue volume and orbital size and gradual absorption of some grafted materials. Here, the authors describe an efficient method of enophthalmos correction using sliced costochondral bone and cartilage combination grafts. METHODS: From 2005 to 2011, the authors corrected enophthalmos in 12 patients using sliced costochondral grafts...

Blow-in fracture of the zygomaticomaxillary complex that was displaced into the orbital cavity could be associated with ophthalmologic injuries, ranging from visual acuity to ocular motility limitation. Appropriate reduction and realignment of the fractured bone is necessary as early as possible for recovery of function and esthetics. However, limitation of accessibility and visibility makes it difficult for delicate surgery and increases the risk of damage of adjacent anatomic structures, such as optic nerve and extraocular muscles...

The aim of this study was to determine the predictive value of a specific computed tomography (CT)-based assessment for the final functional ophthalmological outcome in pure orbital floor blowout fractures. Data of 34 consecutive patients with pure blowout fractures who had undergone a period of at least 6 months of medical and ophthalmological follow-up were analyzed. The following 3 CT scan-based parameters were included: area ratio of the fractured orbital floor (RF), maximum height of periorbital tissue herniation (MH), and a 4-grade muscular subscore (MSS) describing the inferior rectus muscle displacement relative to the orbital floor level...

INTRODUCTION: The zygomaticomaxillary complex is very vulnerable to injury because of its intrinsically prominent convexity. There are 2 different surgical approaches for the therapy of these fractures: closed reduction and open reduction. In the open reduction 2 or 3 fixation points with related incisions are usually necessary in dislocated fractures: osteosynthesis must be performed starting from zygomaticofrontal suture when dislocated at this site, followed by zygomatic body fixation on the anterior sinus wall, anterior orbital floor margin fixation, and finally orbital floor reconstruction in case of eye globe dislocation with diplopia...

OBJECTIVE: With orbital floor fracture incidence rates increasing year by year, many patients require surgical treatment to improve diplopia, limitation of extraocular muscle movement (EOM), enophthalmos, and midface appearance. With the use of high-density polyethylene, titanium screws, titanium plate, and titanium mesh to repair an orbital floor fracture, enophthalmos and midfacial deformity correction procedures have made great progress. However, attenuating diplopia and the limitation of EOM are still difficult problems to prevent...

BACKGROUND: It is difficult to restore original orbital contours because of their complex 3-dimensional structure. Moreover, slight implant malpositioning can result in enophthalmos or other complications. The authors describe our experience of using individualized prebent titanium-Medpor mesh implants and stereolithographic modeling in a series of patients who underwent orbital wall reconstruction. METHODS: A consecutive series of 104 patients with orbital fractures received computer simulation-designed prebent titanium-Medpor mesh implants insertion...

A rare case of Bacillus panophthlamitis with extension to the prechiasmatic optic nerve secondary to hematogenous spreading after intravenous drug use is presented. A 27-year-old man with a recent history of trauma to the left eye presented with severe left eye pain following a binge of intravenous drug use. Visual acuity (VA) was LP. On examination he had chemosis, proptosis, elevated intraocular pressure, and a complete hyphema. CT-scan identified preseptal swelling, but no evidence of any posterior extension of the anterior process or orbital fractures...

Intraorbital meningoencephaloceles occur most commonly as a complication of traumatic orbital roof fractures. Nontraumatic congenital orbital meningoncephaloceles are very rare, with most secondary to destructive processes affecting the orbit and primary skull defects. Treatment for intraorbital meningoencephaloceles is surgical repair, involving the excision of herniated brain parenchyma and meninges and reconstruction of the osseous defect. Most congenital lesions present in infancy with obvious globe and orbital deformities; we report an orbital meningoencephalocele in a 3-year-old girl who presented with ptosis...

Scott J Farber, Jenny L Yu, Dennis C Nguyen, Albert S Woo
PURPOSE: Retrobulbar hematoma is an uncommon but potentially devastating complication following repair of orbital fractures. Since 2007, the senior author routinely fenestrates the solid porous polyethylene implants commonly used for orbital reconstruction. The perforated implant may facilitate drainage of postoperative bleeding and may potentially reduce the risk of retrobulbar hematoma. This study examines the rates of retrobulbar hematoma in patients who underwent orbital fracture reconstruction with placement of fenestrated or nonfenestrated implants...

PURPOSE: The purpose of our study was to investigate whether the occurrence of preoperative diplopia determines the incidence of postoperative diplopia after orbital floor repair. MATERIALS AND METHODS: We undertook a retrospective cohort study with a review of the records of 126 consecutive patients who had undergone repair of an orbital floor fracture under the maxillofacial surgery service at John Hunter Hospital (Newcastle, NSW, Australia). The primary predictor variables were a number of demographic, etiologic, and operative factors that might influence the occurrence of diplopia...
