Article
Reconstruction and rehabilitation following rhinectomy remains controversial and presents a complex problem. Although reconstruction with local and microvascular flaps is a valid option, the aesthetic results may not always be satisfactory. The aesthetic results achieved with a nasal prosthesis are excellent; however patient acceptance relies on a...
Article
The efficacy of computer-aided technologies in the design and manufacture of maxillofacial prostheses has not been fully proven. This paper presents research into the evaluation of direct and indirect additive manufacture of a maxillofacial prosthesis against conventional laboratory-based techniques. An implant/magnet-retained nasal prosthesis case...
Article
The authors present the clinical results of their method of customized reconstruction of orbital wall defects using titanium mesh or sheet. High resolution computed tomography (CT) data are imported and processed to create a three-dimensional (3D) image which is used to reconstruct the orbital defect. Mirror imaging of the air in the contralateral...
Article
Full-text available
This case study presents a method of utilizing computer-aided design technologies to provide bespoke, external breast prostheses. The technique is illustrated through a case study of a mastectomy patient. Photogrammetry methods were used to capture the breast form when supported by a brassiere and the unsupported breast and defect side. Computer-ai...
Article
Purpose – Maxillofacial prosthetics is faced with increasing patient numbers and cost constraints leading to the need to explore whether computer‐aided techniques can increase efficiency. This need is addressed through a four‐year research project that identified quality, economic, technological and clinical implications of the application of digit...
Article
Full-text available
Purpose The computer‐aided design (CAD) and manufacture of custom‐fitting surgical guides have been shown to provide an accurate means of transferring computer‐aided planning to surgery. To date guides have been produced using fragile materials via rapid prototyping techniques such as stereolithography (SLA), which typically require metal reinforce...
Article
Full-text available
We present a high-quality display system that enables the remote access within an operating theatre of high-end medical imaging and surgical planning software. Currently, surgeons often use printouts from such software for reference during surgery; our system enables surgeons to access and review patient data in a sterile environment, viewing real-...
Article
This pilot research aims to identify and assess suitable technologies that may be used to capture, create, and produce fine textures and wrinkles that may be incorporated into computer aided prosthesis design and production techniques. A range of suitable technologies is identified and two methods that may be used in different prosthetic rehabilita...
Article
This paper is the first in a series that aims to identify the specification requirements for advanced digital technologies that may be used to design and fabricate complex, soft tissue facial prostheses. Following a review of previously reported techniques, appropriate and currently available technologies were selected and applied in a pilot study....
Article
The aim of this study was to acquire information on the types and longevity of implant-retained facial prostheses and the opinions of patients on several factors related to their prostheses. A survey of 75 maxillofacial prosthetic patients currently under treatment and review at the Maxillofacial Unit, Morriston Regional Hospital was conducted thro...
Article
Hernia formation following harvest of bicortical iliac crest bone occurs infrequently as a late complication and may lead to chronic pain at the donor site and rarely to obstruction and strangulation of bowel. We describe the use of a custom-made titanium plate used to reconstruct the iliac donor site following harvest of a DCIA composite free flap...
Article
Three-dimensional Computer Tomography (CT) data from a recent scan was used to obtain facial anatomy from a patient requiring an ocular prosthesis. The CT data was imported into the computer aided design (CAD) package, FreeForm® that was used to digitally design the prosthesis pattern using sculpting and shaping tools. The digital prosthesis patter...
Article
The capture of highly accurate data describing the complex surfaces of the human body may prove extremely useful in many medical situations. The data provide a method of measuring and recording changes to the surface of a patient's soft tissue. The data may be applied to computer-controlled manufacturing techniques, such as rapid prototyping (RP)....
