ABSTRACT
Resumen El objetivo de este trabajo es discutir la presentación y el manejo de la aplasia congénita unilateral del cartílago alar. En este informe, presentamos el caso de un paciente sometido a rinoseptoplastia abierta primaria que presenta aplasia congénita del cartílago alar izquierdo que se repara con cartílago septal. Se discute el manejo de casos y se revisa la literatura. Las anomalías nasales congénitas son poco frecuentes. La ausencia aislada de cualquier estructura nasal específica es aún más rara. El diagnóstico preoperatorio en una nariz hispana es difícil, pero cuando se encuentra este defecto congénito, puede repararse con cartílago septal u otros tipos de cartílago, dependiendo de la disponibilidad del injerto, con buenos resultados. Se recomienda un enfoque abierto para este tipo de patología. La aplasia unilateral del cartílago alar podría reconstruirse con éxito utilizando el cartílago septal a través de un abordaje abierto.
Abstract The objective of this work is discussing the presentation and management of unilateral congenital aplasia of the alar cartilage. In this report, we present the case of a patient undergoing primary open rhinoseptoplasty presenting congenital aplasia of the left alar cartilage that is repaired with septal cartilage. Case management is discussed, and the literature is reviewed. Congenital nasal abnormalities are rare. The isolated absence of any specific nasal structure is even more rare. Preoperative diagnosis in a Hispanic nose is difficult, but when this deformed congenital is found, it can be repaired with septal cartilage or other types of cartilage, depending on the availability of the graft, with good results. An open approach is recommended for this type of pathology. Unilateral alar cartilage aplasia could be successfully reconstructed using septal cartilage through and open approach.
ABSTRACT
BACKGROUND: Injectable biomaterials have attracted increasing attention for volume restoration and tissue regeneration. The main aim of this review is to discuss the current status of the injectable biomaterials for correction of tissue defects in plastic and reconstructive surgery. METHODS: Requirements of injectable biomaterials, mechanism of in situ gelation, characteristics, and the combinational usage of adipose-derived stem cells (ADSCs) and growth factors were reviewed. RESULTS: The ideal injectable biomaterials should be biocompatible, non-toxic, easy to use, and cost-effective. Additionally, it should possess adequate mechanical properties and stability. In situ gelation method includes physical, chemical, enzymatic and photo-initiated methods. Natural and synthetic biomaterials carry their pros and cons due to their inherent properties. The combined use of ADSCs and growth factors provides enhanced potential for adipose tissue regeneration. CONCLUSION: The usage of injectable biomaterials has been increasing for the tissue restoration and regeneration. The future of incorporating ADSCs and growth factors into the injectable biomaterials is promising.

Autologous fat grafting has become a commonly used technique in the plastic and reconstructive surgery, due to its availability and biocompatibility and are considered an ideal material for soft-tissue augmentation. We provide a review of the current literature, summarize the current status of autologous fat grafting, including the fat grafting process, complications, and postoperative follow-up, and offer a reference for the clinical application and basic research of autologous fat transplantation.
ABSTRACT
La disminución del volumen de la estructura esquelética de la cara ocasiona flacidez de todos los elementos que se apoyan sobre ella y es una de las causas más importantes de su caída. Dado que no contamos con un recurso efectivo para lograr la recuperación del volumen óseo, lo indicado es restaurar la relación entre las partes blandas y el volumen óseo vigente. Ésta es la meta más importante de la ritidectomía subperióstica. Describimos la aplicación de este procedimiento miniinvasivo para la restauración de la región frontal. Se describen las metas y medios para realizarlo por vía frontal, transpalpebral y combinando ambas vías, así como los procedimientos auxiliares asociados, los detalles del manejo posoperatorio, las complicaciones, las observaciones resultantes de nuestra experiencia con este método a lo largo de 10 años y la razón de que actualmente sea nuestro procedimiento de elección.
Reduction of the bony structure of the face is the main reason for flabbiness and drooping of the facial soft tissues. Because we do not currently have recourse to restore the lost bony volume, a good possibility is to reestablish an optimal relationship between the soft tissues and the present bony volume. Based on this principle, we have developed the procedure of mini-invasive subperiosteal facial restoration. In this paper we describe the application of this procedure to restore the frontal region. The maneuvers and instrumentation used to perform this procedure through frontal, palpebral or the combination of both approaches are described. Based on the surgical anatomy, orientation and instructions for obtaining the goals of the procedure and to avoid complications are elucidated. Ancillary procedures that may be associated with this procedure are described, as well as detailed postoperative care. Observed complications are noted and a summary of the obtained results, which have shown a high degree of patient and surgeon satisfaction, are reported. Observations from our experience with this method during a 10-year period and the reasons for this being the procedure of our first choice are revealed.

ABSTRACT
The brief history of human tissue bank is reviewed, and the current status of tissue bank in the field of plastic surgery in Korea is presented. We sent a questionnaire to 58 plastic and reconstructive surgery training hospitals. The survey was completed in 27 hospitals. The results were as follows : the number of hospitals managing a tissue bank was 16, and the remaining 11 hospitals did not manage a tissue bank. Less than 30% of the plastic and reconstructive surgery training hospitals' tissue banks were managed by the plastic and reconstructive department by itself. In the field of plastic surgery in Korea, skin banks are most popular among the tissue banks. The development of the national skin bank is needed and there are a lot of parts to be improved in the management of tissue banks.
