Study 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. Conclusions We developed a low cost, reproducible, open-source simulator for subcondylar mandibular fractures. Face and Content validity was achieved through evaluation by a group of experts.

RESUMENLos adhesivos de cianoacrilatos (ACA) son materiales sintéticos con propiedades adhesivas. Al ser aplicados en los tejidos polimerizan uniéndose con el tejido subyacente. Desde la década de los 70' se han explorado sus aplicaciones quirúrgicas para el cierre de heridas y fístulas, control de sangrado y fijación de injertos, entre otros, siendo su uso como alternativa para el cierre de heridas en piel y mucosas uno de los más estudiados. Los ACA presentan un limitado grado de absorción, sin evidencia de efectos tóxicos sistémicos. Tienen la ventaja de ser aplicados de forma rápida, indolora, con efecto antibacteriano y hemostático según los reportes de la literatura, pero presentan una reducida fuerza de tensión. El objetivo de esta revisión de la literatura es describir los usos y aplicaciones de los ACA, con enfoque en la cirugía oral y maxilofacial, evaluando de forma crítica sus aplicaciones.

ABSTRACTThe cyanoacrylate adhesives (ACA) are synthetic materials with adhesive properties. When is applied in tissues, it polymerizes and bonds with the underlying tissue. Since the 70s' have been explored their surgical applications for closing wounds, fistulas, bleeding control, and graft fixation, among others. Its use as an alternative for closing wounds in skin and mucous is one of the most studied. The ACA have a limited absorption degree, with no evidence of systemic toxic effects. They have the advantage of being applied quickly, painlessly, with antibacterial effect and hemostatic according to the report of literature, but with reduced tensile strength. The objective of this literature review is to describe the use and applications of ACA, with focus on oral and maxillofacial surgery, with a critically evaluation of their applications.

Objective: 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 publication 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.
