眼窩下壁骨折の治療材料に関する検討：u-HA / PLLAプレートとチタンメッシュプレートの比較

抄録

　　Although the usage of absorbable plates for the treatment of orbital floor fractures is well established, there are only a few reports on the comparison of titanium mesh plates and standard osteosynthesis material.
　　In this study, we used a composite of unburned hydroxyapatite (u-HA) and poly-L-lactic acid (PLLA) as an absorbable plate (u-HA/PLLA), and compared it with a titanium mesh plate in terms of operative time and mid- to long-term complications over a six-month period after surgery.
　　On comparison of the 67 patients (50 patients with u-HA/PLLA plate and 17 patients with titanium mesh plate), the operative time was significantly shorter in the titanium mesh plate group (P<0.05). For complication rate comparison, 48 patients (35 with u-HA/PLLA plate and 13 with titanium mesh plate) were followed up in an outpatient setting for more than 6 months after surgery, but no significant difference between the two groups was found.
　　Both u-HA/PLLA and titanium mesh plates are excellent materials with few complications; therefore, it is necessary to consider both materials on a case-by-case basis.
