a current 10 year retrospective survey of 199 surgically treated Orbital Floor fractures in a nonurban tertiary care center
Plastic and Reconstructive Surgery, 2001Co-Authors: Lawrence Tong, Richard J Bauer, Steven R BuchmanAbstract:This study characterizes the surgically treated patient population suffering from Orbital Floor fractures by use of current data from a large series consisting of 199 cases taken from a nonurban setting. Data were gathered through a retrospective chart review of patients surgically treated for Orbital Floor fractures at the University of Michigan Health System, collected over a 10-year period. Data regarding patient demographics, signs and symptoms of presentation, cause of injury, nature of injury, associated facial fractures, ocular injury, and associated nonfacial skeleton trauma were collected. In total, there were 199 cases of Orbital Floor fractures among 189 patients. Male patients outnumbered female patients by a 2:1 ratio and were found to engage in a wider range of behaviors that resulted in Orbital Floor fractures. Motor vehicle accidents were the leading cause of Orbital Floor fractures, followed by physical assault and sports-related mechanisms. The ratio of impure to pure Orbital Floor fracture was 3:1. The most common signs and symptoms associated with Orbital Floor fractures, in descending order, were periOrbital ecchymosis, diplopia, subconjunctival hemorrhage, and enophthalmos. Associated facial fractures were found in 77.2 percent of patients, the most prevalent of which was the zygoma-malar fracture. Serious ocular injury occurred in 19.6 percent of patients, with globe rupture being the most prevalent, accounting for 40.5 percent of those injuries. There was a 38.1 percent occurrence of associated nonfacial skeletal trauma; skull fracture and intracranial injury were the most prevalent manifestations. Associated cervical-spine fractures were rare (0.5 percent). Statistical examination, using odds ratios and chi-squared analysis, demonstrated significant associations that have not previously been reported. Impure and pure Orbital Floor fractures revealed striking differences in several demographic aspects, including mechanism of injury, signs and symptoms of presentation, spectrum of associated trauma, and the severity of concomitant trauma.

endoscopic endonasal reduction of blowout fractures of the Orbital Floor
Otolaryngology-Head and Neck Surgery, 2004Co-Authors: Yasuyuki Hinohira, Eiji Yumoto, Ichiro ShimamuraAbstract:Abstract Objectives: This study is to show the usefulness of the endoscopic endonasal approach in the surgical treatment of isolated blowout fractures of the Orbital Floor. Methods: Between 1997 and 2003 we operated on 65 patients complaining of diplopia due to isolated blowout fractures of the Orbital Floor, including 4 patients accompanied with enophthalmos. In 62 of the 65, only the endonasal approach with endoscope was used, while in the remaining 3 patients, we used the combined endonasal and transantral approach. To do the endonasal repair surgery smoothly under the endoscope, via the middle nasal meatus, septoplasty was supplemented in 13 patients and submucous conchotomy in 57. The bone fragments trapping the Orbital content herniated into the maxillary sinus were carefully removed so as to keep the periorbita intact. Tampon gauzes or a balloon catheter for temporal fixation was placed in the maxillary sinus through the middle nasal meatus to support the Orbital Floor for 2 to 7 days. No permanent supporting material was used. Immediately following the repair and the fixation the eye traction test was respectively performed to confirm that the eyeball was freely moving. Results: Postoperatively diplopia disappeared in 50 of the 57 patients using only the endonasal approach, (87.7%) and enophthalmos improved 3 of 4 followed over 6 months. Conclusions: From this high success rate with respect especially to diplopia we conclude that the endoscopic endonasal approach is alternative to extranasal methods in view of cosmetics and the improvement of eye movement.

endoscopic endonasal repair of Orbital Floor fracture
Archives of Otolaryngology-head & Neck Surgery, 1999Co-Authors: Katsuhisa Ikeda, Hideaki Suzuki, Takeshi Oshima, Tomonori TakasakaAbstract:Background High-resolution endoscopes and the advent of endoscopic instruments for sinus surgery provide surgeons with excellent endonasal visualization and access to the Orbital walls. Objective To demonstrate repair of Orbital Floor blowout fractures through an intranasal endoscopic approach that allows repair of the Orbital Floor fracture and elevation of the Orbital content using a balloon catheter without an external incision. Design This study was a retrospective analysis of 11 patients who underwent surgical repair of Orbital Floor fractures from September 1994 to June 1997. There were 10 male patients and 1 female patient, aged 12 to 32 years (mean age, 24 years). These patients had undergone primary repair of pure Orbital blowout fractures and were followed up at least 6 months after surgery. Results There were no intraoperative or postoperative complications. Nine patients showed a complete improvement of their diplopia. Two patients with posterior fractures showed persistent diplopia, which was well managed by prisms. Conclusion Endoscopic repair of the Orbital Floor blowout fracture using an endonasal approach appears to be a safe and effective technique for the treatment of diplopia.
