Ceramic orbital implant: a study of the efficacy, acceptability and safety of a locally produced hydroxyapatite orbital implant for the anophthalmic socket

摘要

ABSTRACTudA novel locally manufactured and developed porous hydroxyapatite orbital implant hasudbeen investigated and found to be as safe as commercially available implants.udObjectiveudTo describe and analyze the results of twenty orbital implants implanted into patients inudone arm of a multicentre trial.udMethodsudA porous hydroxyapatite orbital implant with a smooth cap was developed and implantedudinto twenty patients. These patients were followed up for a period of four months.udPatients were examined for signs of infection or extrusion of the implants. The amount ofudpost-operative pain, chemosis, granuloma formation and vascularity was also assessed.udResultsudNone of the twenty patients had any signs of extrusion or infection at the termination ofudthe study. There was very little pain or chemosis noted and no granuloma formation.udConclusionudThe locally developed implants were safe in anophthalmic eyes when reviewed after audfour month follow-up period.
