Abstract
Background Various materials are available for the reconstruction of bone defects in cases of medial wall blowout fracture. This study was conducted to assess the efficacy of the combination of a resorbable meshed plate and cancellous bone allograft. Methods From March 2014 to March 2017, a total of 111 patients were evaluated. Sixty-three patients received reconstruction surgery with porous polyethylene plates (control group) and the other forty-eight patients underwent operation with a resorbable meshed plate plus allogenic cancellous bone (combined group). The results were assessed by exophthalmometric measurements, width, and volume discrepancies as compared with the unaffected orbit, and operation time. Results The difference in exophthalmometric measurements between the affected and unaffected orbits were 0.94 ± 0.70 mm in the control group and 1.05 ± 0.73 mm in the combined group without statistical significance (p = 0.425). In the analysis of computed tomography images, the width discrepancy was 1.55 ± 0.86 mm and 1.08 ± 0.69 mm, respectively (p = 0.003); however, the volume discrepancy demonstrated no statistically significant difference (2.58 ± 1.40 cm3 versus 2.20 ± 1.80 cm3; p = 0.209). Operation time was significantly shorter in the combined group as compared with the control group (43.0 ± 7.0 versus 38.3 ± 7.0 minutes; p = 0.001). Conclusion The combination material composed of resorbable meshed plate and cancellous bone allograft made reconstruction surgery of medial wall blowout fracture easier and quicker to perform with long-lasting results.
Highlights
Blowout fracture is de ned as a fracture that involves the orbital walls, especially the medial wall and/or orbital oor [1]
Functional and aesthetic sequelae, such as diplopia or enophthalmos, could occur as they do in orbital oor blowout fractures [4]. erefore, if the patient presents with diplopia or enophthalmos and/or extensive fracture is observed in computed tomography (CT) images, surgical reconstruction is recommended [2]
A total of 111 patients were enrolled in this study. 63 patients were assigned to the control group and the other 48 patients were placed in the combined group
Summary
Blowout fracture is de ned as a fracture that involves the orbital walls, especially the medial wall and/or orbital oor [1]. Erefore, if the patient presents with diplopia or enophthalmos and/or extensive fracture is observed in computed tomography (CT) images, surgical reconstruction is recommended [2]. Various substances such as autogenous materials (e.g., autologous bone, cartilage, and fascia), allogenic materials, nonresorbable alloplastic materials (e.g., titanium, porous polyethylene, hydroxyapatite), and resorbable alloplastic materials (e.g., poly-L-lactic acid, polyglycolic acid, polyglactin, BioMed Research International composite polymers) can be used in the reconstruction of medial orbital wall fractures and defects [1, 5, 6]. E combination material composed of resorbable meshed plate and cancellous bone allogra made reconstruction surgery of medial wall blowout fracture easier and quicker to perform with long-lasting results Conclusion. e combination material composed of resorbable meshed plate and cancellous bone allogra made reconstruction surgery of medial wall blowout fracture easier and quicker to perform with long-lasting results
