Immediate and long-term results of unsintered hydroxyapatite and poly L-lactide composite sheets for orbital wall fracture reconstruction

Bone defect reconstruction in orbital wall fractures with absorbable alloplastic, such as unsintered hydroxyapatite and poly L-lactide composite (u-HA/PLLA), is gaining popularity. This material is osteoconductive and osteosynthetic. However, quantitative, long-term outcome data after use for orbital wall fractures are lacking.
