While sharp, penetrating trauma is often associated with group A Streptococcus (GAS) infections and subsequent necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS), there are scant reports in the oral and maxillofacial surgery literature regarding blunt, non-penetrating trauma in association with these conditions. With a clinical course that initially appears relatively benign following blunt trauma, NF can progress swiftly through the fascial planes and may quickly become life-threatening if the oral and maxillofacial surgeon fails to recognize some of the critical pathognomonic signs...

PURPOSE OF REVIEW: The current study reviews the recent literature on pediatric orbital blowout fractures and provides guidelines on their management. RECENT FINDINGS: The most common problem among patients requiring surgical revision of a previously repaired orbital floor fracture is an improperly placed orbital floor implant, usually erroneously placed under the posterior bony ledge. Although the transconjunctival incision can be combined with a lateral canthotomy and cantholysis, excellent surgical exposure can be obtained without the need for these latter relaxing maneuvers...

Periorbital injury can present with various permutations of bone trauma, soft-tissue edema, and hematomas that might involve proptosis and restricted motility. We report a case of a 32-year-old patient who sustained a traumatic orbital compartment syndrome simultaneously with a large, significantly displaced, orbital-floor blow-out fracture. Clinical signs consistent with both conditions were elicited. The initial management was as for orbital compartment syndrome. The clinical diagnosis was confirmed with computed tomographic imaging...

Orbital floor fractures pose a grave threat for injury to the infraorbital nerve, resulting in the patient suffering from a disturbing paraesthesia. It is challenging for the operating surgeon to release and secure the entrapped nerve with reconstruction of the orbital floor. We present an interesting case of orbital floor fracture with entrapped infraorbital nerve, wherein we have decompressed the nerve and provided it, a new course.

Orbital floor fractures (OFF) with entrapment require prompt clinical and radiographic recognition for timely surgical correction. Correct CT radiographic interpretation of entrapped fractures can be subtle and thus missed. We reviewed the clinical, radiographic and intraoperative findings of 45 cases of entrapped OFF to correlate pre- and intraoperative findings with radiography. Retrospective review and statistical analysis of 45 patients with OFF using the chi squared and Kruskal-Wallis tests. Main outcome measures included patient demographics, clinical features, radiologic interpretation, intraoperative findings, and treatment outcomes...

The sensory innervation of the inferior eyelid is mainly derived from the inferior palpebral branch (IPb) of the infraorbital nerve (ION). This study aimed to investigate another, to our knowledge, previously unknown branch, and elucidate its location and distribution. Twelve sides from seven fresh frozen cadaveric Caucasian heads were used in this study. The specimens were derived from two male and four female adult cadavers age. The diameter of the IPb of the ION (D1) and branch arising from the upper wall of the infraorbital canal (D2), and distance between the branching points of this branch and the anterior border of the orbit floor (L1) was measured...

In situ splitting of rib bone graft was conducted in 22 patients for the repair of orbital fracture with no other complicating fractures. A bone graft was harvested from the sixth or seventh rib in the right side. The repair of the orbital floor and medial wall was successful in all the cases. Ten patients had bone grafting to the orbital floor, eight had it done onto medial wall, and 4 onto both floor and wall after reduction. The mean length of in situ rib bone graft was 40.9 mm (range, 20-70 mm), the mean width of these was 14...

PURPOSE: Intraoperative imaging is gaining widespread use in the management of facial fracture repair. The aim of this study was to determine whether intraoperative imaging changes the management of orbital fracture repair. MATERIALS AND METHODS: A retrospective case series was performed of all cases of orbital fracture repair from 2008 to 2015 in which the intraoperative O-arm was used at Regions Hospital (St Paul, MN), a level I trauma center. The primary outcome variable was a change in management, ranging from orbital plate repositioning to proceeding with orbital floor exploration...

A 36-year-old man presented because of nasal obstruction, rhinorrhea, and postnasal drip. The patient had undergone reconstruction of a blow-out fracture of the orbital floor 12 years before and had sinusitis that likely had resulted from implant migration into the maxillary sinus. The inflammation was successfully resolved, and the implant was removed through a minimally invasive endoscopic sinus surgery technique. On pathologic examination, an organizing hematoma was identified as the cause of the lesion...

This study aimed to establish the incidence of postoperative nausea and vomiting (PONV) in facial fracture patients. The specific aim was to investigate the effect of perioperative dexamethasone on PONV. A total of 119 adult patients with facial fractures were analysed in this prospective study. Patients were randomized to receive perioperatively either a total dose of 30mg of dexamethasone i.v. and i.m., or no glucocorticoid (control). PONV was evaluated every 6hours during the first postoperative 24hours and when pain medications were given...

Large orbital fractures in older patients are infrequently associated with an exaggerated oculocardiac reflex. This report describes the case of a patient in his 40s with a large right orbital floor and medial wall fracture without radiographic evidence of extraocular muscle compression or entrapment who developed severe nausea and bradycardia with movement of his affected eye. The patient exhibited bradycardia to 17 beats per minute during the initial examination and was taken urgently to the operating room for reconstruction of the right orbital floor and medial wall...

INTRODUCTION: Silent sinus syndrome is an unusual cause of progressive enophthalmos and hypoglobus due to atelectasia of the maxillary sinus associated with osteolysis of the orbital floor. This syndrome is classically idiopathic, but the term is also used to describe traumatic or iatrogenic (surgical orbital decompression) cases. CASE REPORT: We report the case of a 33-year-old man who presented with a left orbital trauma without functional disorder. Computed tomography (CT) scan revealed a nondisplaced fracture of the left orbital floor...

In patients with fractures of the zygomatic complex, computed tomography (CT) often identifies extensive defects in the orbital floor. Some surgeons recommend routine exploration and repair of these defects during repair of the zygoma, while others advocate a more selective approach, but there is a paucity of evidence either way. We report a retrospective case series of 50 patients who had open reduction and internal fixation of zygomatic fractures by a single surgeon in the maxillofacial department at the John Radcliffe Hospital, Oxford, between 2011and 2014...

PURPOSE: We will aim to develop implants made of a Ni-Ti shape memory alloy which can be applied for the treatment of midface fractures, such as isolated orbital floor fractures. These can then be implanted in a compressed form and unfold automatically in the body. With the help of newly developed application instruments, the implants can be applied along transnasal and transantral approaches into the maxillary sinus. Our objective is to evaluate the operation process and the functionality of these implants, already in a pre-investigation by an experienced surgeon on a phantom...

Importance: Orbital floor fractures are commonly seen in clinical practice, yet the etiology underlying the mechanism of fracture is not well understood. Current research focuses on the buckling theory and hydraulic theory, which implicate trauma to the orbital rim and the globe, respectively. Objective: To elucidate and define the biomechanical factors involved in an orbital floor fracture. Design, Setting, and Participants: A total of 10 orbits from 5 heads (3 male and 2 female) were used for this study...

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...
