[The reason and management of the sunken upper eyelid after hydroxyapatite platform implantation].

Objective: To study the reason and the management of the sunken upper eyelid after implanting a hydroxyapatite platform.

Methods: From 1998, we developed a method of subperiosteal implantation at the orbital floor to repair the introcession of the upper eyelid after hydroxyapatite platform implantation. 11 cases of the sunken upper eyelid were treated with this method. The implants included Medpor in 2 cases, hydroxyapatite plates in 7 cases and acellular dermal matrix in 2 cases.

Results: Postoperatively, all the patients obtained satisfactory results. Follow-up for 1 to 4 years showed no complications of extrusion or infection of the implants. Re-operation was needless in all of them.

Conclusion: Subperiosteal implantation to correct the sunken upper eyelid is a safe and effective method.
