Role of orthoptics and scoring system for orbital floor blowout fracture:surgical or conservative treatment

AIM:To assess the role of orthoptics in referring patients with orbital floor blowout fracture(OFBF)for conservative or surgical treatment and based on the results,to propose a scoring system for such decision making.METHODS:A retrospective analysis of 69 patients with OFBF was performed(35 treated conservatively,34 surgically).The role of orthoptics in referring to surgery or conservative treatment was retrospectively evaluated,the factors with the highest significance for decision making were identified,and a scoring system proposed using Logistic regression.RESULTS:According to defined criteria,the treatment was unsuccessful in 2(6%)surgically treated and only in one(3%)conservatively treated patient.The proposed scoring system includes the defect size and several values resulting from the orthoptic examination,the elevation of the eyebulb measured on Lancaster screen being the most significant.CONCLUSION:The study demonstrates the benefits of orthoptic examination when making decisions on conservative or surgical treatment and for diagnosing ocular motility disorder(with or without binocular diplopia)in OFBF patients.The proposed scoring system could,following verification in a prospective study,become a valuable adjunctive tool.

Orbital Floor Fractures: Epidemiological, Clinical and Therapeutical Study at Sylvanus Olympio University Teaching Hospital in Loméabout 51 Cases

Introduction: Orbital floor fractures are a significant pathology among maxillofacial injuries. They can cause oculomotor, sensory, and sometimes esthetic disorders. The goal of this study was to determine the epidemiological profile of orbital floor fractures and show their clinical and therapeutic approach in Lomé. Patients and method: This was a descriptive retrospective study of orbital floor fractures collected in the ENT and maxillofacial surgery department of Sylvanus Olympio University Hospital in Lomé over 8 years (January 1, 2011 to December 31, 2018). Results: We reviewed 63 cases of orbital floor fractures out of 552 cases of facial trauma. According to the inclusion and non-inclusion criteria, we retained 51 cases. The hospital frequency of orbital floor fractures was 9.24% of facial fractures. The average age of the patients was 35 ± 10.34 years. Males were predominant (ratio = 7.5). The main etiology was road accidents (92.16%). Ophthalmological signs were dominated by vertical diplopia (31.37%), limited eye movement (25.49%), and enophthalmia (29.41%). The sensory sign was dominated by suborbital hypoesthesia (13.73%). Surgical treatment was performed in 86.27% of patients. The average intervention time was 17.84 ± 12.69 days after the trauma. The main approach was the subciliary route (65.91%). The surgical procedures consisted of muscle and fat removal (20.45%) and orbital floor repair by mesh plate (50%). The average length of hospitalization was 9.63 ± 5.23 days. Surgical site infection was the main postoperative complication observed in 3.92% of patients. The main sequelae were diplopia (4.55%), suborbital hypoesthesia (4.55%), and enophthalmos (4.55%). Conclusion: Orbital floor fractures are mainly due to road accidents. Management must be multidisciplinary and adequate in order to avoid irreversible functional and/or morphological sequelae. Their prevention consists of effective combat of road accidents.
