Improvement of Infraorbital Rim contour Using Medpor

Abstract

BackgroundAsymmetry of the infraorbital rim can be caused by trauma, congenital or acquired disease, or insufficient reduction during a previous operation. Such asymmetry needs to be corrected because the shape of the infraorbital rim or midfacial skeleton defines the overall midfacial contour.MethodsThe study included 5 cases of retruded infraorbital rim. All of the patient underwent restoration of the deficient volume using polyethylene implants between June 2005 and June 2011. The infraorbital rim was accessed through a subciliary approach, and the implants were placed in subperiosteal space. Surgical outcomes were evaluated using preoperative and postoperative computed tomography studies.ResultsImplant based augmentation was associated with a mean projection of 4.6 mm enhancement. No postoperative complications were noted during the 30-month follow-up period.ConclusionBecause of the safeness, short recovery time, effectiveness, reliability, and potential application to a wide range of facial disproportion problems, this surgical technique can be applied to midfacial retrusion from a variety of etiologies, such as fracture involving infraorbital rim, congenital midfacial hypoplasia, lid malposition after blepharoplasty, and skeletal changes due to aging.

New methods for craniofacial bone reconstruction: review

“…(really high-thickness porous polyethylene) is a non-resorbable, and uneasy moulded polymer that has been in many cases utilized in the minimal floor of orbit deserts (23). This type of material has a smooth external surface and is incredibly biocompatible because the holes grant the improvement of veins and connective tissue (24). Medpor showed that titanium facial reconstructions got autologous bone tissue, yet illness rates were lower (7).…”

Biocompatible Materials for Orbital Wall Reconstruction—An Overview

“…Medpor (ultra-high-density porous polyethylene) is a non-resorbable, easy-to-shape polymer that has been frequently used in small orbital floor defects [ 56 ]. This material has a smooth surface and very good biocompatibility because the pores allow the formation of connective tissue and blood vessels [ 57 ]. The results obtained with Medpor were similar to those obtained with autologous bone tissue, but infection rates were lower [ 28 ].…”

One-piece Craniofacial Bone Fracture Reduction With an Additional Single Osteotomy at the Zygomaticomaxillary Buttress: A Successful Reduction of Frontoorbitozygomaticomaxillary Fracture Associated With a Temporoparietal Bone Fracture

“…F acial bone fractures are common medical conditions widely discussed in plastic surgery. [1][2][3][4][5][6]7 When this type of facial bone fracture is associated with a temporoparietal bone fracture, the fracture extends to involve the bones in the temporal and parietal regions of the skull. The temporal bone forms the lower lateral sides of the skull, and the parietal bone forms the upper sides.…”
