Alison B Callahan, Ashley A Campbell, Carisa Petris, Michael Kazim
PURPOSE: Despite its increasing use in craniofacial reconstructions, three-dimensional (3D) printing of customized orbital implants has not been widely adopted. Limitations include the cost of 3D printers able to print in a biocompatible material suitable for implantation in the orbit and the breadth of available implant materials. The authors report the technique of low-cost 3D printing of orbital implant templates used in complex, often secondary, orbital reconstructions. METHODS: A retrospective case series of 5 orbital reconstructions utilizing a technique of 3D printed orbital implant templates is presented...

Fracture of the anterior skull base can occur following head injury. Growing skull fracture is usually observed in children under age of 3-years. It commonly involves frontal and parietal regions. However, orbit involvement is extremely uncommon. Authors report a case of giant orbital encephalocele with a forehead disfiguring swelling in a 4-years boy, who sustained head injury about 3½ years back. However, such delayed presentation of traumatic encephalocele is extremely uncommon and represents the first case in the Western literature, who had a successful postoperative outcome...

Orbital blowout fractures are a common occurrence following orbital trauma. Depending on the size of the defect and the contents that have herniated or incarcerated, possible sequelae include enophthalmos, diplopia, dystopia, and entrapment. Surgical intervention aims to prevent or alleviate this through the use of a bone graft or an alloplastic implant to reconstitute the continuity of the orbit. However, in doing so, the implant itself may result in the unexpected adherence of the periorbita, resulting in orbital adherence syndrome...

The etiology of fractures of the maxillofacial skeleton varies among studies, with motor vehicle accidents and assaults oftentimes the most common. The number of males outnumbers females throughout most studies. Fractures of the zygoma, orbit, and mandible are usually cited as most common fracture types. This study examines a single center's experience with regards to etiology and distribution of fractures. A retrospective review of all radiologically confirmed facial fractures in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012...

The aim of this study was to analyze the use of C-arm and its significance in accurate reduction of zygomaticomaxillary complex (ZMC) fractures. Orbital volume is used as parameter to compared pre- and postoperative volumes of injured orbit. Differences in orbital volume calculated in cases done with intraoperative imaging and in controls treated without the use of intraoperative imaging were evaluated using Student t-test. C-arm is definitively an effective tool in the armamentarium of oral and maxillofacial surgery in assessment of reduction of ZMC fracture...

Traumatic orbital roof fractures are rare and are managed nonoperatively in most cases. They are typically associated with severe mechanisms of injury and may be associated with significant neurologic or ophthalmologic compromise including traumatic brain injury and vision loss. Rarely, traumatic encephalocele or pulsatile exophthalmos may be present at the time of injury or develop in delayed fashion, necessitating close observation of these patients. In this article, we describe two patients with minimally displaced blow-in type orbital roof fractures that were later complicated by orbital encephalocele and pulsatile exophthalmos, prompting urgent surgical intervention...

Virtual surgical planning (VSP) has recently been introduced in craniomaxillofacial surgery with the goal of improving efficiency and precision for complex surgical operations. Among many indications, VSP can also be applied for the treatment of congenital and acquired craniofacial defects, including orbital fractures. VSP permits the surgeon to visualize the complex anatomy of craniofacial region, showing the relationship between bone and neurovascular structures. It can be used to design and print using three-dimensional (3D) printing technology and customized surgical models...

BACKGROUND: The reported rate of isolated medial orbital wall fractures varies widely but has been found to be as high as 55% of all orbital fractures. Identifying and repairing medial orbital wall defects by using appropriate materials improves patient outcome considerably; however, most related research has focused on orbital floor defect management rather than medial orbital wall treatment, and no consensus on repairing medial orbital wall fractures exists. Furthermore, medial orbital wall fracture is a main cause of posttraumatic enophthalmos...

Farm workers are at increased risk for animal-inflicted head injuries that are associated with significant morbidity and occasionally may be fatal. These injuries may cause permanent eye damage with or without concomitant skull base fracture. Here, we present a male farmer who suffered a cow attack that resulted in perforating orbital injury with comminuted frontobasal cranial fracture caused by a cow's horn. The next day, the patient developed nasal and orbital cerebrospinal fluid (CSF) leak. Computed Tomography cisternography revealed CSF leakage to frontal and maxillary sinuses...

The infraorbital nerve (ION) can easily be damaged by orbital trauma and periorbital surgical manipulations, due to its abutment to the orbital floor. Anatomic variability of the ION and surrounding structures has infrequently been documented. The aim of this study is to give precise anatomical knowledge about the ION with surrounding structures, to avoid iatrogenic injury of the ION during periorbital procedures.Forty orbits of 40 skull subjects (20 males and 20 females) were studied to analyze structures around the ION...

Injury to the peripheral sensory branches of the trigeminal nerve can follow a wide variety of craniofacial injuries. Many patients with facial fractures complain about the symptom of numbness to the distribution of injured nerve, which is indicative of hypoesthesia. Hyperesthesia involving the infraorbital nerve is rare in comparison to hypoesthesia secondary to facial trauma. The authors report on 2 patients with infraorbital nerve hyperesthesia in surgically repaired orbital fracture patients. Surgical decompression of the infraorbital nerve led to rapid resolution of hyperesthesia...
