internal fixation in trapdoor type orbital Blowout Fracture
Plastic and Reconstructive Surgery, 2005Co-Authors: Jin Sik BurmAbstract:Background: The most common orbital Blowout Fracture is a trapdoor type. In many cases of trapdoor Fracture, the bony segment has a stable hinge consisting of a greenstick Fracture and the sinus mucoperiosteum that is attached to the intact orbital wall. If the displaced bony segment opposite the hinge is reduced into the original position and fixed on the unaffected bone, the orbital Fracture may be reconstructed by internal fixation of the bony segment itself rather than requiring substitution with alloplastic implants or a bone graft. Methods: In 20 cases of orbital Blowout Fracture of a trapdoor type, internal fixation was performed using a cantilever fixation technique (with a piece of titanium micromesh or a titanium microplate plus a microscrew) or a ledge fixation technique (with a piece of micromesh). Results: In all cases, the orbital wall was accurately reconstructed in its normal anatomical position. The associated ocular problems disappeared except for mild diplopia in one patient and there were no surgical complications associated with the internal fixation. Conclusions: The advantages of internal fixation include anatomical reconstruction of the orbital wall; preservation of the original orbital bone and the mucoperiosteum of the sinus as an osteomucoperiosteal flap resulting in rapid wound healing and normal mucus drainage function of the sinus; the simplicity of the procedure; and con-sequently, the absence of surgery-related complications. This technique is presented as one of the preferred treatments for trapdoor-type orbital Blowout Fractures.

pure orbital Blowout Fracture new concepts and importance of medial orbital Blowout Fracture
Plastic and Reconstructive Surgery, 1999Co-Authors: Jin Sik Burm, Chul Hoon Chung, Suk Joon OhAbstract:Pure orbital Blowout Fracture first occurs at the weakest point of the orbital wall. Although the medial orbital wall theoretically should be involved more frequently than the orbital floor, the orbital floor has been reported as the most common site of pure orbital Blowout Fractures.

prognostic ct findings of diplopia after surgical repair of pure orbital Blowout Fracture
Journal of Cranio-maxillofacial Surgery, 2016Co-Authors: Hyena Jung, Jae Young Byun, Gyeong Min ParkAbstract:Abstract Purpose Diplopia is a common sequela of Blowout Fracture even after proper surgical management. We investigated the prognostic factors of diplopia after surgery of pure Blowout Fracture. Materials and methods We retrospectively reviewed CT images of 181 patients with pure orbital Blowout Fracture who underwent at least six months of postoperative follow-up. We evaluated the following CT factors: (1) Fracture site (orbital floor, medial wall of the orbit, or both), (2) Fracture type (closed flap, open flap), (3) Fracture size, (4) volume of herniated orbital soft tissue, (5) ratio of volume of herniated orbital soft tissue to Fracture size, (6) number of points of contact between extraocular muscle (EOM) and bony edge, (7) presence of EOM thickening, (8) EOM swelling ratio, (9) presence of displacement of EOM, (10) presence of deformity of EOM, (11) presence of tenting of EOM, and (12) presence of entrapment of EOM. The associations between diplopia at six months after surgical repair and various risk factors were analyzed using logistic regression models for univariable and multivariable analyses. Results EOM tenting and deformity and ratio of volume of herniated orbital soft tissue to Fracture size were found to be statistically significant risk factors of diplopia at six months after repair on univariable analysis (all P Conclusion The prognosis of patients was predicted by CT evaluation. Patients who have tenting or deformity of EOM on CT scan are more likely to have postoperative diplopia.

surgical timing of the orbital Blowout Fracture a systematic review and meta analysis
Otolaryngology-Head and Neck Surgery, 2016Co-Authors: Olaf E. Damgaard, Ulrik Ascanius Felding, Peter B. Toft, Christian Gronhoj Larsen, Christian Von BuchwaldAbstract:ObjectiveThe orbital Blowout Fracture is a common facial injury, carrying with it a risk of visual impairment and undesirable cosmetic results unless treated properly. Optimal timing of the surgical treatment is still a matter of debate. We set out to determine whether a meta-analysis would bring us closer to an answer to this question.Data SourcesPubMed, EMBASE, Web of Science, and the Cochrane Library were searched from January 1980 to August 2014. We applied the following inclusion criteria: isolated Blowout Fractures, presenting early and late surgery groups ( 14 days). Patients were evaluated for diplopia and enophthalmos.Review MethodsWe followed the statements of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Pooled odds ratios were estimated with the fixed effects method of Mantel-Haenszel.ResultsWe identified 5 studies with available outcome data (N = 442). Patients in the late group showed an odds ratio of 3.3 (P = .027) for persistent postoperative diplopia...

the white eyed medial Blowout Fracture
Plastic and Reconstructive Surgery, 2007Co-Authors: Larry H Allen, Damir B MaticAbstract:BACKGROUND: The pediatric white-eyed Blowout Fracture with entrapment of the inferior rectus muscle is well recognized as an easily missed injury with significant morbidity if left untreated. A series of five isolated medial orbital Blowout Fractures with medial rectus muscle entrapment is described. The purpose of this study was to define this injury pattern and its clinical outcome. METHODS: A retrospective review of the presentation, management, and clinical outcomes of identified cases was conducted. RESULTS: Early exploration and release of the entrapped muscle combined with implant reconstruction of the medial orbital wall within 2 weeks resulted in complete resolution of diplopia and full recovery of extraocular movements. Delayed treatment and release of the soft tissues without orbital wall reconstruction were associated with restricted gaze and diplopia. Similar outcomes were confirmed on analysis of other reported cases. CONCLUSIONS: Orbital floor Blowout Fractures in the pediatric population have a high incidence of muscle entrapment that must be recognized and treated early to avoid muscle necrosis and permanent ocular restriction from fibrosis. Medial orbital wall Fractures with entrapment are rare, but early recognition and operative release of the entrapped muscles result in better outcomes.
