Soft-tissue loss presents an ongoing challenge in plastic and reconstructive surgery. Standard approaches to soft-tissue reconstruction include autologous tissue flaps, autologous fat transplantation and alloplastic implants. All of these approaches have disadvantages, including donor-site morbidity, implant migration and absorption and foreign body(More)
BACKGROUND Several techniques for lipoinjection have been described in the literature. Recently, the role of adult stem cells in adipose tissue has gained interest. OBJECTIVES The authors compare autologous fat transplantation to adipose-derived stem cell-enriched lipografts. METHODS A group of 20 patients with congenital or acquired facial tissue(More)
This article provides an up-to-date review of the strategies used in auricular cartilage engineering. The currently available options in stem cell, biomaterial and bio-molecules and the crucial issues for the auricular cartilage engineering are presented. Researchers have demonstrated that neo-cartilage can be constituted in a predetermined shape and in(More)
Tissue engineering is an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function. This field has enjoyed tremendous growth in the past 10 years fuelled by its potential role in regenerating new tissues and naturally healing(More)
OBJECTIVE to present a retrospective analysis on the clinical-functional results and complications among patients with rotator cuff arthropathy (RCA) who underwent reverse arthroplasty of the shoulder. METHODS patients with a diagnosis of RCA associated with pseudoparalysis of anterior elevation who underwent reverse arthroplasty of the shoulder with a(More)
The diagnosis of basosquamous cell carcinoma is controversial. A review of cases of basal cell carcinoma showed 23 cases that had conspicuous areas of squamous cell carcinoma. This was distinguished from squamous differentiation and keratotic basal cell carcinoma by a comparative study of 40 cases of compact lobular and 40 cases of keratotic basal cell(More)
Adipose tissue is believed to constitute an ideal source of uncultured stromal stem cells. By optimizing the harvesting, storage, and transplantation of adipose tissue, long-lasting results can be obtained. Cell-assisted lipotransfer (CAL) is a novel approach to autologous fat transplantation in which adipose-derived stem cells are attached to the aspirated(More)
BACKGROUND Tissue engineering has the potential to provide ear-shaped cartilaginous constructs in the near future. Previous attempts to engineer human ear-shaped constructs mimicked human shape and characteristics but were done in immunocompromised animal models. OBJECTIVES The authors design and evaluate a novel, 3-dimensional (3D) cell-copolymer(More)
