    A Hollow Tridimensional Silicone Template for Microtia Reconstruction and Postoperative Scar Compression
    (2023) Gloria Morovic, Carmen; Ester Hidalgo, Maria; Tejos, Rodrigo; Ramirez, Andrea; Jorquera, Claudia
    Microtia poses a great challenge in auricular reconstruction, due to a great number of anatomical details on the anterior aspect, and its tridimensional shape. Numerous techniques have been described in an attempt to optimize results. We have designed a hollow tridimensional silicon template to serve as an intrasurgical guide for ear's anatomy, size and projection, according to the normal side, which allows better results of auricular reconstruction. It also can be used as a customized post-operative compression method. We believe it could be a valuable tool for microtia reconstruction surgery.

    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.

    Lobectomía video-asistida por puerto único utilizando un nuevo modelo de simulación ex vivo perfundido
    (2016) Ávila Sepúlveda, Rubén; Achurra Tirado, Pablo; Tejos, Rodrigo; Varas Cohen, Julián; Solovera Rozas, María; Salas Villarroel, Patricio; Pontificia Universidad Católica de Chile. Escuela de Medicina
    La simulación puede proporcionar una solución para adquirir habilidades avanzadas en cirugía torácica, sin embargo, hasta la fecha de publicación de este artículo no hay informes sobre un modelo ex vivo perfundido. Desarrollamos un modelo de bajo costo y alta fidelidad utilizando una muestra ex vivo en bloque de corazón y pulmón de un cerdo. El cerdo se usó previamente en un experimento no torácico, por lo que extrajimos el pulmón y el corazón para este modelo basado ex-vivo para reducir el uso de animales. El costo del modelo completo es de 70 USD y se puede reutilizar muchas veces cambiando el tejido ex vivo, por lo que este modelo puede ayudar a reducir los costos y el uso de animales asociados a esta cirugía de alta complejidad.

    MicrosimUC: Validation of a Low-Cost, Portable, Do-It-Yourself Microsurgery Training Kit
    (2021) Navia, Alfonso ; Tejos, Rodrigo ; Canahuate, Sebastian ; Machuca, Eduardo ; Searle, Susana ; Cuadra, Alvaro ; Dagnino, Bruno
    Background Microsurgery depends largely on simulated training to acquire skills. Courses offered worldwide are usually short and intensive and depend on a physical laboratory. Our objective was to develop and validate a portable, low-cost microsurgery training kit.

    Video-based guided simulation without peer or expert feedbackis not enough : a randomized controlled trial of simulation based training for medical students
    (2021) Tejos, Rodrigo; Crovari Eulufi, Fernando; Achurra Tirado, Pablo; Ávila, Rubén; Inzunza, Martín; Jarry, Cristián; Martínez C., Jorge; Riquelme Pérez, Arnoldo; Alseidi, Adnan; Varas, Julián
    Background Feedback is a pivotal cornerstone and a challenge in psychomotor training. There are different teaching methodologies; however, some may be less effective. Methods A prospective randomized controlled trial was conducted in 130 medical students to compare the effectiveness of the video-guided learning (VLG), peer-feedback (PFG) and the expert feedback (EFG) for teaching suturing skills. The program lasted 4 weeks. Students were recorded making 3-simple stitches (pre-assessment and post-assessment). The primary outcome was a global scale (OSATS). The secondary outcomes were performance time, specific rating scale (SRS) and the impact of the intervention (IOI), defined as the variation between the final and initial OSATS and SRS scores. Results No significant differences were found between PFG and EFG in post-assessment results of OSATS, SRS scores or in the IOI for OSATS and SRS scores. Post-assessment results of PFG and EFG were significantly superior to VLG in OSATS and SRS scores [(19.8 (18.5–21); 16.6 (15.5–17.5)) and (20.3 (19.88–21); 16.8 (16–17.5)) vs (15.7 (15–16); 13.3 (12.5–14)) (p \0.05)], respectively. The results of PFG and EFG were significantly superior to VLG in the IOI for OSATS [7 (4.5–9) and 7.4 (4.88–10) vs 3.5 (1.5–6) (p \0.05)] and SRS scores [5.4 (3.5–7) and 6.3 (4–8.5) vs 3.1 (1.13–4.88) (p \0.05)], respectively. Conclusion The video-guided learning methodology without any kind of feedback is not enough for teaching suturing skills compared to expert or peer feedback. The peer feedback methodology appears to be a viable alternative to handling the emerging demands in medical education.
