Comparative Study Review
Irrespective of the cause, abnormalities in shape, size, and position of body organs are often perceived as looking wrong. This perception can subject the individual to significant peer ridicule and social ostracism. Rehabilitation of patients with auricular defects can either be done by reconstructive surgery or by prosthetic means. The article draws a comparison between the implant-supported prosthesis and reconstructive surgery, listing the benefits, limitations, indications and contraindications of both the techniques. As both the available techniques give excellent results in appropriately selected situations, the restorative team must present all the alternatives to the patient and choose judiciously the better of the two.

Observational Study
Lack of the testis is an important factor in psycho-sexual development of the boys, and implantation of the prosthesis plays a very essential role in the treatment of that group of patients. Currently there are no standards regarding when prosthesis should be implanted, and which access is connected with minimal rates of complications. We present our experience of primary prosthesis implantations in boys treated in our department.From 2000 to 2014, primary implantation of the testicular prosthesis was performed in 290 boys. The early and late post-operative complications and long-term therapeutic results were analyzed, considering age at the time of implantation, the time between the initial operation and implantation of the prosthesis, and the surgical approach.Best results were observed in 267 patients and bad outcome in 23 patients. Prosthesis implantation in young boys operated within the first three years of life or during the first year after primary surgery was connected with statistically fewer complications (P = .002 and P < .05, respectively). Supra-scrotal access was connected with the lowest rate of complications (P = .01).Long-term therapeutic results in boys with testicular prostheses were good in the majority of cases. Implantation of the first prosthesis should be performed early between 1 and 3 years of life in boys with lack of the testis. Implantation of a prosthesis should also be performed within 1 year after removing of testis or during orchiectomy. Supra-scrotal access should be chosen for testicular prosthesis implantation due to the best long-term results.

This article argues for the value of considering the interaction of literary/cultural studies, disability studies and engineering/design studies in the ongoing development of a critical medical humanities research frame. With a specific focus on prosthesis, but also considerations of embodiment, technology and augmentation as concepts in both cultural/disability theory and engineering/design, we note how the shifting and plastic ideas of 'the prosthetic' as used within cultural studies have never been in conversation with scholars who work on prostheses in engineering design or the processes through which such technologies are produced. Additionally, we show that the increased use of systems engineering in the design and construction of prostheses creates fractured ideas of disabled bodies that frequently ignore both the cultural meaning and lived experience of technology use. In design and engineering, prostheses are literal objects, often made to order for a diverse range of clients and produced across different working platforms; in cultural studies, the word creates multiple resonances around both augmented bodies and non-embodied states increasingly understood in terms of assemblage and supplementarity. Working from this, we outline how questions of metaphor, materiality and systems weave through the different disciplines. The article claims that a critical dialogue between the working methods of literary/cultural studies and engineering/design, for all their obvious differences, possesses the potential to create informed and sophisticated accounts of disability embodiment. Our conclusion brings the strands of the enquiry together and points to the merits of engineering the imagination, and imagining engineering, as both a subject and method in future medical humanities research.

Review
The cornea is the transparent front part of the eye that transmits light to the back of the eye to generate vision. Loss of corneal transparency, if irreversible, leads to severe vision loss or blindness. For decades, corneal transplantation using human donor corneas has been the only option for treating corneal blindness. Despite recent improvement in surgical techniques, donor cornea transplantation remains plagued by risks of suboptimal optical results and visual acuity, immune rejection and eventually graft failure. Furthermore, the demand for suitable donor corneas is increasing faster than the number of donors, leaving thousands of curable patients untreated worldwide. Here, we critically review the state of the art of biomaterials for corneal regeneration. However, the lessons learned from the use of the cornea as a disease model will allow for extension of the biomaterials and techniques for regeneration of more complex organs such as the heart.

Review
Implanted medical devices are widely used across various medical specialties for numerous applications, ranging from cardiovascular supports to orthopedic prostheses and cosmetic enhancements. However, recent observations have raised concerns about the potential of these implants to induce malignancies in the tissues surrounding them. There have been several case reports documenting the occurrence of cancers adjacent to these devices, prompting a closer examination of their safety. This review delves into the epidemiology, clinical presentations, pathological findings, and hypothesized mechanisms of carcinogenesis related to implanted devices. It also explores how the surgical domain and the intrinsic properties and biocompatibility of the implants might influence the development of these rare but serious malignancies. Understanding these associations is crucial for assessing the risks associated with the use of medical implants, and for developing strategies to mitigate potential adverse outcomes.

Review
INTRODUCTION
Testicular prostheses produced from various materials have been in use since 1941. The absence of a testicle has been shown to be a psychologically traumatic experience for males of all ages. The indications for insertion of a prosthesis include absence or following orchidectomy from a number of causes such as malignancy, torsion and orchitis. The most common substance used around the world in the manufacture of these implants is silicone; however, in the US, this material is currently banned because of theoretical health risks. This has led to the development of saline-filled prostheses as an alternative.
PATIENTS AND METHODS
A Medline search was carried out on all articles on testicular prosthesis between 1966 and 2006.
CONCLUSIONS
This review highlights the controversies regarding prosthetic materials, the complications of insertion and the potential benefits of this commonly performed procedure.

Review
PURPOSE
This study aimed to review the current state of the techniques and materials used to rehabilitate maxillofacial defects.
MATERIALS AND METHODS
The MEDLINE and EMBASE databases were searched for articles pertinent to maxillofacial prostheses published from January 1990 to July 2011. The main clinical stages were the subject of analysis.
RESULTS
A multidisciplinary approach is preferred when rehabilitating maxillofacial defects. Surgical reconstruction can be used for smaller defects, but larger defects require a prosthesis to achieve an esthetic rehabilitation. Implant retained prostheses are preferred over adhesive prostheses. Silicone elastomer is currently the best material available for maxillofacial prostheses; however, longevity and discoloration, which are greatly influenced by ultraviolet radiation, microorganisms, and environmental factors, remain significant problems. In the near future, the widespread availability and cost effectiveness of digital systems may improve the workflow and outcomes of facial prostheses. Patients report high satisfaction with their prostheses despite some areas that still need improvement.
CONCLUSIONS
Maxillofacial prostheses are a reliable treatment option to restore maxillofacial defects and improve quality of life. Significant progress has been made in the application of implants for retention and digital technology for designing surgical guides, suprastructures, and craniofacial prostheses. Further improvements are necessary to enhance longevity of prostheses.
