Abstract:Bioabsorbable sheet-shaped implants made of forged composites of unsintered hydroxyapatite and poly-L-lactide (F-u-HA/PLLA) have been used for orbital fracture repair with good results. This is the first report using multiple specimens implanted in the human orbit to demonstrate the biodegradation and loss of strength of F-u-HA/PLLA sheets. Among the patients who underwent various facial fracture repairs with F-u-HA/PLLA sheets implanted in their orbits, those whose sheets were subsequently extracted were incl… Show more
