  • Title: Repair of orbital floor fractures with hydroxyapatite block scaffolding.
    Author: Lemke BN, Kikkawa DO.
    Journal: Ophthalmic Plast Reconstr Surg; 1999 May; 15(3):161-5. PubMed ID: 10355833.
    Abstract:
    PURPOSE: To determine the efficacy of using a scaffold of hydroxyapatite blocks within the maxillary sinus to treat patients with large orbital floor fractures and secondary vertical globe dystopia. METHODS: Case series of five patients. Hydroxyapatite blocks were stacked within the maxillary antrum to support the reconstructed orbital floor. RESULTS: All patients had good results, though mild residual enophthalmos persisted in three patients. The orbital floor implants and globe positions remained stable during follow-up intervals ranging from 46 to 65 months. No adverse postoperative complications, such as sinusitis, developed. CONCLUSIONS: Hydroxyapatite block scaffolding is a useful alternative to metallic floor implants and autologous bone grafts in the reconstruction of large traumatic orbital floor defects associated with vertical globe dystopia.
