Abstract:
Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.
