Comparison of Porous Polyethylene Sheet(Medpor(R)) with Titanium Dynamic Mesh in the Treatment of Blow Out Fracture

ABSTRACT

The records of the patients with orbital wall fracture were reviewed from March 1997 through February 2001 in the department of plastic and reconstructive surgery, Yeungnam university medical center. One hundred thirty nine patients with blow out fracture were repaired by using porous polyethylene(Medpor(R)) or titanium dynamic mesh. Surgical effect of titanium dynamic mesh was evaluated and compared with that of Medpor(R) in the reconstruction of orbital wall fracture after follow up period of six months. The incidence of the orbital wall fracture was more common in men than in women. The traffic accident was most common cause of the fracture and the most common combined fracture was nasal bone fracture. The sites of fractures were the orbital floor in 51 patients, the medial wall in 18 patients, and both the medial wall and floor in 38 patients. Medpor(R) is easy to handle, shape, contour and position. Titanium dynamic mesh is good device in that it has for good structural stability, excellent strength, high biocompatibility and can be fixed easily. In conclusion, Medpor(R) was suitable for local defect in small fracture and titanium dynamic mesh was suitable for large defect in compound fracture
