ABSTRACT Objective: to compare the acquisition and retention of knowledge about surgical cricothyroidostomy by the rapid four-step technique (RFST), when taught by expository lecture, low fidelity and high-fidelity simulation models. Methods: ninety medical students at UFPR in the first years of training were randomized assigned into 3 groups, submitted to different teaching methods: 1) expository lectures, 2) low-fidelity simulator model, developed by the research team or 3) high-fidelity simulator model (commercial). The procedure chosen was surgical cricothyroidostomy using the RFST. Soon after lectures, the groups were submitted to a multiple-choice test with 20 questions (P1). Four months later, they underwent another test (P2) with similar content. Analysis of Variance was used to compare the grades of each group in P1 with their grades in P2, and the grades of the 3 groups 2 by 2 in P1 and P2. A multiple comparisons test (post-hoc) was used to check differences within each factor (test and group). Statistical significance was considered when p<0.05. Statistical analysis was performed in the statistical software R version 3.6.1. Results: each group was composed of 30 medical students, without demographic differences between them. The mean scores of the groups of the expositive lecture, of the simulator of low fidelity model and of high-fidelity simulator model in P1 were, respectively, 75.00, 76.09, and 68.79, (p<0.05). In P2 the grades were 69.84, 75.32, 69.46, respectively, (p>0.05). Conclusions: the simulation of low fidelity model was more effective in learning and knowledge retention, being feasible for RFST cricothyroidostomy training in inexperienced students.

“…7–28 Of these articles, eight (36 per cent) were prospective cohort studies. 11,12,14,16,17,21,23,28 The cohort studies objectively measured surgical skill (utilising a septoplasty model, a functional endoscopic sinus surgery model, a transcanal endoscopic ear surgery model, an otosclerosis prosthesis model, a needle cricothyroidotomy model and a costal cartilage airway grafting model), and demonstrated varying levels of construct validity. The other 14 articles (64 per cent) were cross-sectional studies.…”

Three-dimensional printing as a tool in otolaryngology training: a systematic review

et al. 2019

View full text Add to dashboard Cite

ObjectiveThree-dimensional printing is a revolutionary technology that is disrupting the status quo in surgery. It has been rapidly adopted by otolaryngology as a tool in surgical simulation for high-risk, low-frequency procedures. This systematic review comprehensively evaluates the contemporary usage of three-dimensional printed otolaryngology simulators.MethodA systematic review of the literature was performed with narrative synthesis.ResultsTwenty-two articles were identified for inclusion, describing models that span a range of surgical tasks (temporal bone dissection, airway procedures, functional endoscopic sinus surgery and endoscopic ear surgery). Thirty-six per cent of articles assessed construct validity (objective measures); the other 64 per cent only assessed face and content validity (subjective measures). Most studies demonstrated positive feedback and high confidence in the models’ value as additions to the curriculum.ConclusionWhilst further studies supported with objective metrics are merited, the role of three-dimensional printed otolaryngology simulators is poised to expand in surgical training given the enthusiastic reception from trainees and experts alike.

“…The value of using 3-dimensional (3D) printing to plan surgery, specifically in maxillofacial reconstruction, is to reduce operative time and increase both patient and surgeon confidence in the procedure. [2][3][4][5][6][7] The use of prebent plates in mandibular reconstruction using patient-specific 3D modeling techniques has been reported to significantly decrease operative time and improve accuracy of the reconstruction. 8 It was recognized that time savings, while valuable in a highresourced setting, could be even more valuable in a lowresourced setting, such as Haiti, where operating time and supplies are very limited.…”

Initial Experience Using 3-Dimensional Printed Models for Head and Neck Reconstruction in Haiti

et al. 2020

This report describes the first use of a novel workflow for in-house computer-aided design (CAD) for application in a resource-limited surgical outreach setting. Preoperative computed tomography imaging obtained locally in Haiti was used to produce rapid-prototyped 3-dimensional (3D) mandibular models for 2 patients with large ameloblastomas. Models were used for patient consent, surgical education, and surgical planning. Computer-aided design and 3D models have the potential to significantly aid the process of complex surgery in the outreach setting by aiding in surgical consent and education, in addition to expected surgical applications of improved anatomic reconstruction.
