This study analyzed risk factors for extrusion of orbital implants after evisceration by comparing patients with and without implant extrusion. Methods: We retrospectively reviewed the medical records who underwent primary placement a single surgeon from January 2005 to December 2019 at Chungnam National University Hospital. Age, sex, underlying systemic diseases, axial length fellow eye, cause...

PURPOSE To investigate the current practice of enucleation with or without orbital implant for retinoblastoma in countries across the world. METHODS A digital survey identifying operation techniques and material used for orbital implants after enucleation in patients with retinoblastoma. RESULTS We received a response of 58 surgeons in 32 different countries. A primary artificial implant is...

The aim of the study was to assess factors leading revision surgery and implant position primary orbital fracture reconstructions. A retrospective cohort included patients who underwent floor and/or medial wall reconstruction for recent trauma. Demographics, type, implant-related variables, postoperative were analyzed. overall rate 6.5% (15 232 surgeries). highest in combined midfacial fracture...

Virtual surgical planning (VSP) has recently been introduced in craniomaxillofacial surgery with the goal of improving efficiency and precision for complex surgical operations. Among many indications, VSP can also be applied for the treatment of congenital and acquired craniofacial defects, including orbital fractures. VSP permits the surgeon to visualize the complex anatomy of craniofacial reg...

To investigate the effect of basic Fibroblast Growth Factor (bFGF) on fibrovascular ingrowth into porous polyethylene orbital implants (Medpor) and to investigate any differences according to the method of administration. For the treated groups, after evisceration and Medpor implantation, bFGF was administered by soaking Medpor in the bFGF solution, and/or by injecting bFGF into the Medpor 1 we...

OBJECTIVES The purpose of this study was to evaluate the advantages and limitations of using a silicon tube to support the fractured orbital floor by a transantral approach. METHODS A retrospective study was conducted from January 2000 to December. 2011 in 51 patients with pure orbital floor fractures. The patients underwent reduction surgery via a transantral approach for inserting a folded ...

BACKGROUND Temporalis fascia has been recommended for hydroxyapatite sphere exposure. The aim of this study was to identify potential risk factors for exposure of porous polyethylene (Medpor) sphere implants and evaluate the use of autogenous temporalis fascia as a patch graft for exposure. METHODS A retrospective review of consecutive cases of porous polyethylene sphere orbital implant expos...
