- ItemAgrandamiento gingival por ciclosporina: reporte de un caso(Elsevier, 2016) Campolo González, Andrés Francisco; Núñez Castañeda, Lorena; Romero Romano, Pablo; Rodríguez Schneider, Andrés; Fernández Toro, María de los Ángeles; Donoso Hofer, FranciscaEl agrandamiento gingival (AG) es el aumento de volumen anormal de la encía que genera cambios estéticos y síntomas clínicos como sangrado gingival espontáneo o inducido, trastornos periodontales y migración patológica dentaria, entre otros. Este proceso patológico puede ser un efecto secundario a ciertos fármacos como anticonvulsivantes, bloqueadores de canales de calcio e inmunosupresores. Se presenta el caso de un paciente sexo masculino de 74 años de edad con antecedentes de trasplante renal, en tratamiento con ciclosporina, que acude por aumento del volumen intraoral, clínicamente compatible con agrandamiento gingival. Se realiza tratamiento basado en exodoncias, biopsia y control de placa. A los 2 meses se pudo observar una regresión de la lesión, y se confirma el diagnóstico con el estudio histopatológico. El manejo actual del tratamiento de esta enfermedad se basa en el control de la placa. Se sugiere dar un enfoque multidisciplinario y crear protocolos para derivar oportunamente antes de la expresión más agresiva de la enfermedad.
- ItemCleft lip and palate surgery simulator: Open source simulation model(Elsevier Ltd, 2024) Teuber Lobos, Cristian Andrés; Benítez, Benito K.; Lill, Yoriko; Kiser, Laura E.; Tache, Ana; Fernández Pose, María; Campolo González, Andrés Francisco; Nalabothu, Prasad; Sharma, Neha; Thieringer, Florian M.; Vargas Díaz, Alex Patricio; Mueller, Andreas A.Objective: Cleft lip and palate is the most common craniofacial birth anomaly and requires surgery in the first year of life. However, craniofacial surgery training opportunities are limited. The aim of this study was to present and evaluate an open-source cleft lip and palate hybrid (casting and three-dimensional (3D) printing) simulation model which can be replicated at low cost to facilitate the teaching and training of cleft surgery anatomy and techniques. Design: The soft tissue component of the cleft surgery training model was casted using a 3D printed 5-component mold and silicone. The bony structure was designed to simulate the facial anatomy and to hold the silicone soft tissue. Setting: Two groups, one group of trainees and one group of expert surgeons, at University Hospital Basel in Switzerland and Pontifical Catholic University of Chile in Santiago, Chile, tested the cleft lip and palate simulation model. Participants completed a Likert-based face and content validity questionnaire to assess the realism of the model and its usefulness in surgical training. Results: More than 70 % of the participants agreed that the model accurately simulated human tissues found in patients with unilateral cleft lip and palate. Over 60 % of the participants also agreed that the model realistically replicated surgical procedures. In addition, 80–90 % of the participants found the model to be a useful and appropriate tool for teaching the anatomy and surgical techniques involved in performing unilateral cleft lip and palate repair. Conclusion: This open-source protocol provides a cost-effective solution for surgeons to introduce the cleft morphology and surgical techniques to trainees on a regular basis. It addresses the current financial barrier that limits access to commercially available models during the early stages of surgeon training prior to specialization in the field.
- ItemEffects of hypotensive anesthesia compared to normotensive anesthesia in orthognathic surgeryEfectos de la anestesia hipotensora comparada con la anestesia normotensora en cirugía ortognática(2024) Dallaserra Albertini, Matías; Vargas Buratovic Juan Pablo; Campolo González, Andrés Francisco; Ríos Espósito, Nicolás; Nazar Jara, Claudio; Valladares Pérez, Salvador Rubén; Ortuño Borroto, DunielIntroduction: Orthognathic surgery is widely accepted for correcting dentofacial deformities. Due to the rich blood supply in the head and neck region, considerable bleeding can occur from the incised soft tissues and bone during orthognathic surgery. Hypotensive anesthesia is a method used in surgical practice by which blood pressure is decreased predictably and deliberately to reduce blood loss and improve surgical field. However, there is still uncertainty regarding its effectiveness and safety in orthognathic surgery. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis, and generated a summary of findings table using the GRADE approach. Results and Conclusions: We identified three systematic reviews, including 11 studies overall, which are randomized trials. We concluded that hypotensive anesthesia may reduce intraoperative blood loss and may improve the quality of surgical field, however, the certainty of the evidence has been assessed as low. On the other hand, orthognathic surgery with HA may make little or no difference in surgical time (low certainty evidence). Finally, no studies were found that reported adverse effects or mortality.Introducción: La cirugía ortognática se encuentra ampliamente aceptada para la corrección de anomalías dentofaciales. Debido al importante suministro de sangre en la región de cabeza y cuello, puede ocurrir una considerable pérdida de sangre proveniente de los tejidos duros y blandos intervenidos durante una cirugía ortognática. La anestesia hipotensiva es un método utilizado en la práctica quirúrgica mediante el cual se disminuye de manera predecible y deliberada la presión sanguínea con el fin de reducir la pérdida hemática y mejorar el campo quirúrgico. Sin embargo, aún existe incertidumbre respecto a su efectividad y seguridad en cirugía ortognática. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y Conclusiones: Identificamos tres revisiones sistemáticas, que en conjunto incluyeron 11 estudios primarios, todos ensayos aleatorizados. Concluimos que la anestesia hipotensiva podría reducir la pérdida de sangre intraoperatoria y mejorar la calidad del campo quirúrgico, pero la certeza de la evidencia es baja. Por otro lado, el uso de anestesia hipotensiva podria podría resultar en poca o nula diferencia en el tiempo quirúrgico (certeza de la evidencia baja). Finalmente, no se encontraron estudios que reportaran efectos adversos o mortalidad.
- ItemIncidencia de tromboembolismo venoso en cirugía ortognática(2018) Campolo González, Andrés Francisco; Rioseco Ihnen, Tomás Alonso; Goñi Espildora, Ignacio; Vargas Díaz, Alex Patricio; Ramírez Skinner, HernánIntroducción: El tromboembolismo venoso (TEV) es una causa importante de morbimortalidad en la población hospitalaria y quirúrgica. Esta entidad tiene mecanismos fisiopatológicos bien definidos y descritos, además, de factores de riesgo que permiten una clasificación de los pacientes según diversos modelos de valoración, los cuales permiten adoptar medidas profilácticas. En el ámbito de la cirugía maxilofacial se han descrito bajos niveles de incidencia. Sin embargo, hay evidencia bastante limitada y representa un problema de salud al cual se le ha prestado poca atención en la literatura. Objetivo: El presente estudio tiene como objetivo conocer la incidencia de tromboembolismo venoso en pacientes sometidos a cirugía ortognática. Material y Método: Se evaluaron en forma retrospectiva fichas clínicas de 86 pacientes operados de cirugía ortognática entre octubre de 2006 y enero de 2016 en el Hospital Clínico de la Pontificia Universidad Católica de Chile. Se identificaron 2 casos de tromboembolismo pulmonar, lo cual corresponde a una incidencia de 2,6%. Sin embargo, no se obtuvo un espacio muestral suficiente para lograr identificar factores de riesgo específicos en esta población. Conclusiones: A pesar de la baja incidencia de TEV en pacientes sometidos a cirugía maxilofacial, es fundamental considerar el riesgo individual del paciente y el riesgo que implica la cirugía. La prolongación del tiempo quirúrgico, la estadía hospitalaria y la inmovilización prolongada pueden determinar un riesgo mayor de desarrollar este tipo de complicación, por lo tanto, es necesario considerarla y saber prevenirla de manera adecuada.
- ItemSimulating A Subcondylar Mandibular Fracture With Intraoral Open Reduction and Internal Fixation: A Novel Education Tool for Residents(Sage Publications INC, 2022) Rojas, Francisco; Tapia, Sebastián; Campolo González, Andrés Francisco; Vargas Díaz, Alex Patricio; Ramírez Skinner, Hernan Eduardo; Benítez, Benito K.; Teuber Lobos, Cristian AndrésStudy Design Face and content validation of a surgical simulation model. Objective Open reduction and internal fixation in displaced subcondylar mandibular fractures is standard care. This requires an extraoral (eg: retromandibular, transparotideal) or intraoral approach. An intraoral approach requires further training since specialized instrumentation such as the 90° screwdriver system and endoscopes might be needed. Currently, no simulation models are available for training residents in intraoral reduction and fixation of subcondylar mandibular fractures. Therefore, we present a validated simulation model for intraoral treatment of subcondylar mandibular fractures. Methods Based on a computer tomography data set, we designed and printed a 3D model of a mandible with a unilateral subcondylar fracture. To simulate intraoral work depth, it was positioned inside a dental phantom. We tested the model by a group of experts (n = 8), simulating intraoral reduction and fixation of a unilateral subcondylar fracture, using a 90° screwdriver system, a 1.0 subcondylar plate (lambda), and 5-6 mm screws. We assessed Face and Content validity by survey. Results We provided an open-source printable fracture model. Printing costs were approximately US $10. Experts “Agreed” the model resembling the real scenario and its use for training intraoral reduction and fixation of subcondylar mandibular fractures.
- ItemSurgical treatment of paediatric fractures of the mandibular condyle: a systematic review of the literature(Churchill Livingstone, 2024) Ríos Espósito, Nicolas Felipe; Neira Cisternas, Isidora Valesca; Campolo González, Andrés FranciscoThis study aims to review surgical treatment in paediatric condylar fractures and describe different types of techniques performed, along with the results obtained from them. A retrospective review was conducted from records of paediatric patients (from one to 17 years old) who sustained fractures of the mandibular condyle and underwent surgical treatment from 2003 to 2023. The number of patients, age, location, and type of fracture, clinical and imaging examinations, treatment methods, intraoperative/postoperative complications, removal of osteosynthesis material, follow up and outcomes were recorded and analysed. A total of 68 patients with 79 fractures were identified. The most common fracture pattern was condylar neck fracture (61.1%). Of the 68 patients who underwent surgical treatment, one had a complication of minimal temporal paraesthesia and another patient had near-complete resorption of the condyle. A total of 55 patients (81%) reported normal dental occlusion, mouth opening (>35 mm), lateral excursions (7–8 mm), TMJ function, no pain, no deviation of the midline or the jaw, and no ankylosis. Thirteen patients (19%) developed an unsatisfactory result, nine patients (13%) had a jaw deviation on mouth opening, four patients (6%) had mandibular retrusion, and seven patients (10%) had signs of TMJ dysfunction. A total of 59 patients (87%) reported bone completely healed with no signs of bone abnormality; seven patients (10%) had shortening of the condylar neck and/or ramus. Surgical treatment can lead to good or excellent results for severely dislocated and displaced condylar fractures in children and can reduce the unsatisfactory results resulting from closed treatment.
- ItemUse of autologous platelet derivatives for secondary alveoloplasty in patients with cleft lip and palate: a protocol for a systematic review and meta-analysis(2021) Campolo González, Andrés Francisco; Heider Contreras, Claudia Andrea; Cañete Campos, Ismael Ignacio; Verdugo Paiva, María Francisca; Bravo Jeria, Rocío; Morovic, Carmen Gloria; Rada Giacamán, Gabriel AlejandroObjective: To assess the effectiveness and safety of autologous platelet derivatives, specifically platelet-rich plasma (PRP) or platelet-rich fibrin (PRF), for secondary alveoloplasty in patients with cleft lip and palate. Eligibility criteria: We will include randomized trials evaluating the effect of autologous platelet derivatives on newly bone formed after secondary alveoloplasty in cleft lip and palate patients. Two reviewers will independently screen each study for eligibility, data extraction, and bias assessment using the Cochrane "risk of bias" tool. We will pool the results using meta-analysis and apply the GRADE system to assess the certainty of the evidence for each outcome. Data sources: A comprehensive search will include all relevant randomized controlled trials (RCTs), the ongoing investigation reported in specialty congresses and trials regardless of language or ublication status (published, unpublished, in press, and progress). We will conduct searches in the following databases: Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED, Embase, and LILACS. We will screen trial registries and other sources in order to identify articles that might have been missed in the electronic searches. Ethics and dissemination: As researchers will not access information that could identify an individual participant, obtaining ethical approval was waived.
- ItemUse of autologous platelet derivatives for secondary alveoloplasty in patients with cleft lip and palate: a systematic review and meta-analysis(Churchill Livingstone, 2024) Campolo González, Andrés Francisco; Heider Contreras, Claudia Andrea; Verdugo Paiva, M. F.; Bravo Jeria, R.; Morovic, C. G.; Rada, G.This study aimed to evaluate the effectiveness of autologous platelet derivatives (APD), specifically platelet-rich plasma (PRP) or platelet-rich fibrin (PRF), combined with autogenous iliac crest bone grafts in secondary alveoloplasty for patients with cleft lip and palate. Electronic databases, relevant journals, and reference lists of included studies were searched until July 2022. Best-evidence synthesis was performed to draw conclusions. After the search strategies, 12 randomized controlled trials were included that provided data on six outcomes: newly formed bone, mean bone loss in height and width, bone density, functionality, and postoperative complications. Two authors independently assessed the risk of bias, and the certainty of evidence was assessed using the GRADE approach. The pooled results suggest that there is uncertainty as to whether the combination of APDs with autogenous iliac crest bone grafts improves the percentage of newly formed bone, as the certainty of the evidence was assessed as very low. It may slightly improve the functionality of patients (with low certainty of the evidence) and probably slightly reduces the incidence of postoperative complications (with moderate certainty of evidence). Further randomized clinical trials with standardized methodologies are required to validate these findings.
