[The coral orbital floor. Its value in traumatology. The results of a multicenter study of 83 cases].

A madreporic coral graft was used for orbital floor reconstruction following facial trauma. This report presents a multicentric study of 83 patients with a follow-up period of 15 to 24 months. The results of this study indicate no significant rejection or infection opposed to so many synthetic implants outcome. The radiological follow-up demonstrates a partially resorption of the implant within about 2 years and its replacements by new bone. Coral implant was used to correct enophthalmos or diplopia due to enlarged orbital dimensions. It was technically easy to insert and its anatomic shape does not require to be fashioned before use. Its inflexibility allows to bridge large bone defects and this implant should be considered as an attractive alternative to autogenous grafts, avoiding a second surgical site, in reconstructing orbital floor fractures.
