[Late reconstruction of the orbital floor and zygomatic prominence with a readily vascularized plastic].

An implant made from a new artificial substance "Proplast" consisting of polytetrafluoroethylene and carbon is suitable for the secondary treatment of fractures of the orbital floor and zygoma. Histomorphological studies in animal experiments show rapid vascularisation and tissue ingrowth, which lead to permanent fixation of the implant. Clinical experiments confirm its suitability for the correction of displacement of the eyeball and enophthalmos as well as in the re-establishment of the zygomatic arch. For cosmetic reasons a new operative approach through a combined cantho-conjunctival incision is recommended.
