Edema facial por silicona tratado con minociclina: presentación de un caso / Facial swelling by silicone treated with minocycline

Actualmente las sustancias de relleno son la forma más popular para el rejuvenecimiento facial y el aumento de los tejidos. Existen varios problemas añadidos que han condicionado el aumento de las complicaciones con los materiales de relleno, que son el uso de sustancias adulteradas, la inyección de varios materiales en la misma zona o la administración por personal no entrenado/autorizado. Varias investigaciones sugieren que la ecografía de alta frecuencia (EAF) es una herramienta útil, de bajo coste y no invasiva para demostrar el tipo material de relleno e identificar el lugar de inyección y la cantidad de material inyectado. Presentamos en caso de una mujer de 64 años que presentaba edema hemifacial después de 15 años de haberse inyectado silicona líquida (SIL) en los labios, tratada con minociclina, mostrando mejoría clínica significativa

Currently injectable materials are popular for facial rejuvenation and soft tissue augmentation. There are some added problems, which have been conditioned by the increase in complications with fillers, that are the use of adulterated materials, injections of various types of substances in the same area or because administration by inexperienced/untrained professionals. Several studies suggest that high frequency ultrasound (HUS) is an economical, useful and non-invasive diagnostic tool to determine the nature and type of material and to identify the injection site and quantity of injected filler. We report a case of a 64-year-old woman who presented hemifacial swelling after 15 years of being injected with 1 infiltration of liquid injectable silicone (LIS) in the lips, treated with Minocycline, showing a significant clinical improvement

Plasma rico en plaquetas: fundamentos biológicos y aplicaciones en cirugía maxilofacial y estética facial / Platelet-rich plasma: biology and applications in maxillofacial surgery and facial aesthetics

Esta revisión presenta el uso del preparado de plasma rico en plaquetas (PRP) como una herramienta potenciadora de ciertas características histológicas de los tejidos conformados por células con receptores para los factores de crecimiento plaquetarios. Se ha realizado una revisión sobre el plasma rico en plaquetas de la literatura publicada en PubMed. Se describen los fundamentos biológicos del PRP a nivel celular, la técnica de obtención, y sus usos clínicos en la actualidad(AU)

This review shows platelet-rich-plasma (PRP) as an enhancer of the histological characteristics of the tissues with platelet-derived growth factor receptors. A review has been made of the literature on the platelet-rich plasma published in PubMed. The article describes the cellular biology of PRP, the technique for obtaining it, and its clinical applications(AU)

Lipoescultura facial: técnica quirúrgica y revisión bibliográfica / Facial liposculpture: surgical technique and literature review

Esta revisión presenta la infiltración de grasa autóloga como un procedimiento de gran utilidad para el relleno de las partes blandas faciales con objetivos estéticos o reconstructivos. Se ha realizado una revisión sobre los procedimientos de lipoescultura de la literatura publicada en PubMed. Se describen la técnica de Coleman, la técnica subdérmica, y la infiltración intramuscular, así como sus principales modificaciones, y los agentes estudiados y usados para incrementar la tasa de mantenimiento del injerto graso(AU)

This review shows that autologous fat grafting is useful for filling the soft tissues of the face for cosmetic and reconstructive purposes. The literature on liposculpture techniques published on PubMed was reviewed. The Coleman technique, subdermal technique, and intramuscular infiltration are described, in addition to their primary modifications, and the agents used to improve fat graft maintenance were studied(AU)

Influence of platelet-rich plasma on the histologic characteristics of the autologous fat graft to the upper lip of rabbits.

BACKGROUND: This study evaluated the influence of platelet-rich plasma (PRP) on the histologic characteristics of autologous fat grafts to the upper lip of rabbits. METHODS: Nine New Zealand white rabbits were used. Eight of the rabbits underwent fat harvest from the groin fat pads using a modified Coleman technique. One side of the upper lip was infiltrated with autologous fat and the other side with fat and PRP. Four of the infiltrated rabbits were killed 8 weeks after the lip augmentation, and the remaining four infiltrated rabbits plus one control case were killed 12 weeks after the procedure. Coronal sections of both upper lips were analyzed microscopically to evaluate the quality of the fat graft, the inflammatory reaction, the presence of oil cysts, the degree of fibrosis, and the neovascularization. RESULTS: The infiltration of adipose tissue plus PRP presented less inflammatory reaction (p < 0.05) and fewer oil cysts (p < 0.05) than the infiltration of adipose tissue without PRP. CONCLUSIONS: The infiltration of fat tissue plus PRP generates a lower inflammatory reaction and less formation of oil cysts than the infiltration of isolated fat. Platelet-rich plasma increases the maintenance of the transplanted fat cells.
