BACKGROUND Many implants are being used for the reconstruction of orbital wall fractures. The effect of the choice of implant for the reconstruction of an orbital wall fracture on the surgical outcome is under debate. The purpose of this article is to compare the outcomes of orbital wall reconstruction of small orbital wall fractures on the basis of the implants used. METHODS The authors cond...

A Comparison of Silastic Prostheses (Yeoman design) with Excision Arthroplasty in the Metacarpophalangeal Joints of the Hand Mr. I. M. Pinder (Bath) described a new operative technique for the insertion of a silastic prosthesis. A direct comparison was made of metacarpo-phalangeal replacement in rheumatoid arthritis with excision arthroplasty. Thirty-two replacement arthroplasties had been carr...

A pigment-producing strain of Serratia rubidaea was isolated from two consecutive cultures from a sponge of silastic foam used as a dressing for chronic crural ulcers. The bacterium caused a red discolouration of the sponge and the surrounding part of the leg. The silastic sponge creates a new type of environment for microorganisms. The growth of previously rare bacteria such as S. rubidaea may...

We present a previously unreported late complication of medialization laryngoplasty (ML), also described as a thyroplasty, type 1. Five years following ML with Silastic, a 64-year-old female presented with dysphonia and a mass in the laryngeal ventricle on the ipsilateral side of the ML. A computed tomography scan of the larynx revealed migration of the thyroid cartilage window into the ventric...

Semipermeable silastic rubber membranes can be used to diffuse focally a variety of chemicals including antitumour drugs. Of the eight drugs tested, in vitro tests showed the best diffusion with dactinomycin, mithramycin, and oncovin, and the poorest diffusion with bleomycin, fluorouracil, and thiotepa. Biological testing was performed with mithramycin, dactinomycin, and oncovin using tissue cu...

A quantitative primate model of arterial thromboembolism has been characterized with respect to mechanism and usefulness in evaluating modifying variables. The model involved the kinetic measurements of (51)Cr-platelets and (125)I-fibrinogen consumption by femoral arteriovenous cannulae in chaired baboons. Cannula platelet consumption correlated directly with exposed cannular area for irradiate...

The purpose of this study was to evaluate the Shore A hardness and surface roughness of two silicones for maxillofacial prosthetic treatment, under the influence of chemical disinfection and storage. Twenty-eight specimens were obtained, half of which were made of Silastic MDX 4-4210 silicone and, the other half were made of Silastic 732 RTV silicone. The specimens were divided into four groups...

Use of silicone rubber ('Silastic') prostheses for the replacement of metacarpophalangeal (MCP) joints in rheumatoid arthritis was advocated by Swanson (1969), who considered the overall results of the operation superior to that of all previous surgical techniques. This report presents results of a short-term followup of twelve patients who had silastic MCP implants. Three subjects had joint re...
