Improvement of Infraorbital Rim contour Using Medpor

Ramal bone graft for management of infra-orbital rim fractures with defects - Technical note and a series of 16 cases

The purpose is to describe a technique of using ramal bone graft for reconstructing defects of the infra-orbital rim (IOR), assess outcomes and complications. This was a retrospective chart review of 16 patients who underwent ramal bone grafting for IOR fractures. Outcomes evaluated were improvement in clinical findings (lid/globe malposition, tethering of facial skin and implant extrusion) and complications. Data analysis included descriptive statistics. The sample included 15 males and 1 female, with a mean age of 31.6 years. Lid malposition, globe malposition and tethering of facial skin was seen in 16, 13 and 6 patients, respectively. One patient demonstrated extrusion of implant. The mean size of bone harvested was 14 × 7 mm. All patients demonstrated improved globe position post-treatment, while 3 had residual lid retraction. Two patients demonstrated wound dehiscence in the donor site. In conclusion ramal bone graft was found to be a viable alternative for IOR reconstruction.

Biocompatible Materials for Orbital Wall Reconstruction-An Overview

The reconstruction of an orbit after complex craniofacial fractures can be extremely demanding. For satisfactory functional and aesthetic results, it is necessary to restore the orbital walls and the craniofacial skeleton using various types of materials. The reconstruction materials can be divided into autografts (bone or cartilage tissue) or allografts (metals, ceramics, or plastic materials, and combinations of these materials). Over time, different types of materials have been used, considering characteristics such as their stability, biocompatibility, cost, safety, and intraoperative flexibility. Although the ideal material for orbital reconstruction could not be unanimously identified, much progress has been achieved in recent years. In this article, we summarise the advantages and disadvantages of each category of reconstruction materials. We also provide an update on improvements in material properties through various modern processing techniques. Good results in reconstructive surgery of the orbit require both material and technological innovations.
