Special Issue Information

Dear Colleagues,

With the growing interest in quality of life, the demand for plastic and reconstructive surgery is rapidly increasing, and aesthetic appearance and self-esteem have become important factors beyond functional recovery.

Although biological implants are widely used for functional and cosmetic recovery, short-term safety, including interactions between tissue and implant, and long-term stability of implants, are still controversial. For example, breast silicone implants are still problematic due to capsular contracture or anaplastic large cell lymphoma. The novel development of implant techniques is conducted to achieve desirable biocompatibility as well as mechanical and biophysical properties.

This Special Issue of Applied Sciences on “Current Techniques in Implants for Plastic Surgery” will focus on recent progress in the various fields of solid or soft implants, including metals, polymers, and bioengineered tissues. In particular, advances in biomaterials manufacturing or modification, emerging techniques in 3D printing or bio-scaffolds, and surgical techniques for application of implants to improve the biological and biomechanical property are emphasized. We are pleased to invite you to this Special Issue and hope that much leading research on implants for plastic surgery will be introduced (scientific basis, experimental and clinical studies, etc.).

The purpose of reconstruction of an orbital fracture is restoration of normal structure and volume without visible or functional complications. In a previous study, orbital implants were created using three-dimensional (3D) printing technology to restore orbital fractures. In the present study, the authors compared the efficacy of the conventional manual-bending implant and the 3D-printed standardized implant in order to verify the clinical utility of the fabricated 3D printed orbital implant. In this single-center, retrospective study, the authors evaluated medical records and 3D-CT scans of patients with inferomedial orbital fracture. Selected patients were divided into two groups. Group A underwent surgery with the 3D-printed standardized implant, while group B was treated using a manual technique to mold and trim the implant. A total of 32 patients was included in this study, 16 in each group. The volume of the preoperative lesion side was significantly different from that of the normal side or postoperative lesion side within each group. The volume of the postoperative lesion side was not statistically different from that of the normal side in Group A, but this volume was significantly different from that of the normal side in Group B. The 3D-printed standardized implant provides surgical efficacy to restore inferomedial orbital fracture and has superior surgical outcomes to the manual-bending implant. Full article

Growing evidence has demonstrated that biomimetic nanovesicles produced from specific cells show bioactive properties such as anti-tumor or anti-inflammatory activities. However, the properties of these nanovesicles are very diverse, depending on their cell sources. In this study, human tonsil-derived mesenchymal stem cells (TMSCs) were used in the production of functional biomimetic nanovesicles with anti-senescence. TMSCs were isolated from human tonsil tissue obtained by tonsillectomy. TMSC-derived nanovesicles (TMSC-NVs) were produced by serial extrusion using a mini-extruder. Western blotting and particle analysis were performed for characterization of TMSC-NVs. They were applied to both replicative and ultraviolet B-induced senescent human dermal fibroblasts in vitro. Following six days of treatment, analysis of the proliferation and senescence level of fibroblasts was performed using cell counting and senescence-associated β-galactosidase assay, respectively. Treatment with TMSC-NVs enhanced the cell proliferation and reduced the activity of senescence-associated β-galactosidase in both replicative and ultraviolet B-induced senescent cells. Treatment with TMSC-NVs resulted in increased expression of extracellular matrix and anti-oxidant genes. Treatment with TMSC-NVs resulted in reduced expression of vinculin in focal adhesion. These results show that TMSC-NVs have an effect on recovering from cellular senescence by oxidative stress and can be applied as useful materials for the development of skin rejuvenation.

Breast cancer is one of the most commonly diagnosed malignancies in women. Along with increasing demands for breast reconstruction, the attention given to the psychological and aesthetic benefits of breast reconstruction has also increased. As breast reconstruction and augmentation demands increase, biomaterials for breast reconstruction are being developed, and the related industry is growing quickly worldwide. Among the various biomaterials used for breast enlargement, breast implants have undergone a remarkable evolution since the 1960s. Despite unsatisfactory results and unexpected complications, research dedicated to achieving an ideal breast implant has progressed. In accordance with attention to tissue engineering, a three-dimensional (3D) bioprinting technique for breast tissue regeneration has emerged to overcome the current limitations of breast biomaterials. Along with solid implants, injectable liquid-type fillers are also part of ongoing studies. Full article
