    Desarrollo y validación de modelos de simulación en cirugía plástica.
    (2020) Navia, Alfonso; Dagnino, Bruno; Pontificia Universidad Católica de Chile. Escuela de Medicina
    Introducción: La otoplastía es un procedimiento para corregir orejas prominentes. La simulación ha adquirido gran relevancia en la educación médico-quirúrgica. Objetivos: Desarrollar un modelo de otoplastía a bajo costo y validarlo para su entrenamiento. Material y Métodos: Diseñamos un modelo sintético de oreja prominente. Se utilizó un método Delphi para crear una escala específica para otoplastía (EVOPUC) y un cuestionario de antropometría (CLA). Evaluamos diez participantes, 5 expertos (cirujanos plásticos) y 5 principiantes (estudiantes). Cada participante realizó una otoplastía que se registró en video y fue evaluada por 3 expertos ciegos utilizando una escala general (OSATS), EVOPUC, CLA y el tiempo operatorio. El grupo principiante realizó cuatro sesiones de entrenamiento con expertos. Fueron reevaluados utilizando la misma metodología. Los expertos completaron una encuesta de validez de apariencia y contenido. Resultados: El costo de cada modelo fue 5 dólares. Tras el entrenamiento, los novatos mejoraron significativamente su desempeño (p <0.05), comparables a los expertos. El 100% de los expertos calificó el modelo como muy útil, siendo considerado una herramienta para el entrenamiento de residentes. Conclusiones: Desarrollamos un modelo de otoplastía de bajo costo, logrando una adquisición significativa de habilidades en un grupo principiante, con resultados similares a cirujanos plásticos experimentados.

    Effect of Subcutaneous Lidocaine Infiltration on Blood Loss Secondary to Corporal Lipoaspiration: A Prospective, Randomized, Double-Masked Clinical Trial
    (2009) Llanos, Sergio; Dagnino, Bruno; Ponce, Daniel; Bonacic, Sebastian; Navarrete, Lindaura; Navarrete, Sandra; Mangelsdorff, Guenther; Searle, Susana; Mendez, Ignacio
    Lipoaspiration is one of the most frequently performed aesthetic surgical procedures worldwide. The use of tumescent solution containing lidocaine to infiltrate subcutaneous fat before surgery has been accepted as the standard of care for these procedures. Its objective is to diminish postoperative analgesic necessities and secondary blood loss, but its role in hematocrit reduction is not clear at this time. This study aimed to measure the effect of subcutaneous lidocaine infiltration on blood loss secondary to corporal liposuction.

    Evaluation of Research Opportunities and Limitations for Plastic Surgery Residents An International Survey
    (2021) Navia, Alfonso; Berner, Juan Enrique; Ramirez, Joaquin; Will, Patrick; Tejos, Rodrigo; Dagnino, Bruno; Searle, Susana; Cuadra, Alvaro
    Background Conducting research during specialty training provides an opportunity to develop critical thinking and leadership skills along with a better understanding of the scientific literature. However, trainees often find it difficult to undertake research, in the context of labor-intensive surgical training. The aim of this study is to evaluate the research output and limitations of plastic surgery residents in different countries. Methods An international cross-sectional study involving plastic surgery trainees and recent postgraduates from Brazil, Chile, Germany, and the United Kingdom was conducted. A survey inquiring into academic productivity, limitations to conducting research, and working-hours patterns was distributed among eligible participants. Results From September to December 2019, 106 surveys were retrieved. Most respondents declared having participated in at least 1 project that resulted in a presentation or publication during their training (90.6% in national presentations, 68% international presentations, 67% in national publications, and 66% international publications). Having completed a previous research fellowship was associated with a statistically higher academic output (P < 0.05). Seventy-nine percent of respondents felt that their participation in research activities would have been greater if limiting factors had been addressed, including lack of time (72.5%) and insufficient supervision and mentoring (55%). Conclusions Optimizing plastic surgery trainees' participation in scientific research is beneficial both for residents and their mentors. Research fellowships can provide an opportunity for academically oriented trainees to further develop their research skills. Protected time and adequate mentoring can help not only to increase residents' research output, but also to recruit the next generation of academic plastic surgeons.

    From presentation to publication: an 11-year comparison of aesthetic and reconstructive surgery research among Chilean plastic surgeons
    (2021) Tejos, Rodrigo; Navia, Alfonso; Berner, Juan Enrique; Searle, Susana; Yanez, Gonzalo; Dagnino, Bruno; Guerra, Claudio; Cuadra, Alvaro
    Background The transition from a presentation in a scientific conference to publication in an academic journal should be the ideal journey for a research project. This phenomenon is summarized in a conversion rate, which has been previously reported in the literature. The aim of this study was to determine the characteristics and conversion rate of Chilean authors' aesthetic and reconstructive research projects in a nationwide study. Methods Conference abstracts from the two official Chilean plastic surgery meetings released between 2008 and 2018 were analyzed. A bibliographic search of all published articles involving each Chilean plastic surgeon followed. This information was cross-referenced to obtain the conversion rates and time to publication for transferred studies. Fisher's exact test and Mann-Whitney test were used to establish statistical associations. Results Four hundred sixty-eight abstracts were included, and 227 articles were found in our bibliographic search. Of these, 82 were considered to qualify as transferred studies. Aesthetic surgery publications had a higher proportion of prospective design than reconstructive articles (34.6% vs 20.1% (p= 0.02)). Median time to publication was 15 months, with a longer delay for reconstructive articles (19.5 vs 13 (p= 0.035)). The 2008-2016 conversion rate index was 19.2%, which was significantly higher for aesthetic surgery studies (36.4% vs 11.9% (p< 0.001)). Conclusions Despite a smaller proportion of plastic surgery research being focused on aesthetic topics in our sample, they accounted for higher quality study design, shorter time to publication, and higher overall chances of publication following presentations in local meetings. Level of evidence: Not ratable.

    ¿Implantes mamarios texturizados o lisos para disminuir la tasa de contractura capsular?
    (2017) Cifuentes, Ignacio; Dagnino, Bruno; Rada G., Gabriel
    El uso de implantes mamarios con propósitos estéticos y reconstructivos se ha convertido en uno de los procedimientos más comunes realizados por los cirujanos plásticos. Existen diversos modelos de implantes mamarios, los cuales difieren en su tamaño, relleno, forma y característica de la envoltura, pudiendo ser lisa o texturizada. La contractura capsular es una de las principales complicaciones del uso de implantes mamarios y se ha planteado que las prótesis texturizadas podrían disminuir la incidencia de contractura capsular. Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Identificamos cinco revisiones sistemáticas que en conjunto incluyen 15 estudios primarios, 13 de ellos correspondientes a ensayos aleatorizados pertinentes a la pregunta de interés. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos tablas de resumen de los resultados utilizando el método GRADE. Concluimos que el uso de prótesis mamaria texturizada probablemente disminuye el riesgo de contractura capsular, sin embargo, podría asociarse a un aumento en el riesgo de linfoma anaplásico de células grandes.
