Inion cps® mesh plate was used in orbital floor repair for a (b)(6) year old man.Fluid accumulation was noticed 2.5 months post operatively, and 3.5cc of fluid was drained out by percutaneous needle aspiration.The needle aspiration was repeated 3 times during 8 - 10 months post operatively.No growth of bacteria has been found in fluid collection.The number of patients experiencing this type of tissue reaction is very low.Occurrence rate of degradation related tissue reactions (inion cps®) is 0,15 % as reported to inion.Fluid accumulation is a known adverse event with the bioabsorbable implants, especially if metabolism/vascularity is locally reduced or poor.Tissue reactions such as this are rare, but may occur 1-2 years postoperatively when the device starts to degrade, especially when a plate is implanted under a thin soft tissue layer.Such reaction does not affect bone healing negatively, or cause permanent damage or impairment.The occurrence rate of degradation related tissue reactions has been reported to be very low with polylactic acid based implants, which is in line with inion's post market data.
