Nasopharyngoscopic Velopharyngeal Port Function Assessment: A Randomized Comparative Trial of 3D-Printed Versus Ready-Made Models.

Abstract

Purpose: This study aimed to examine the feasibility and effectiveness of nasopharyngoscopic velopharyngeal port assessment training given to speech-language pathology undergraduate students using a high-cost, ready-made endoscopy training model versus a low-cost, 3D-printed model.

Method: A randomized comparison trial was conducted with 36 final-year undergraduate students from nine different speech-language pathology programs in Türkiye. Participants were randomly assigned to two groups and received training either with ready-made endoscopy model or the 3D-printed model. The training included theoretical and practical components, followed by self-confidence, procedural proficiency, and satisfaction assessments.

Results: Both groups significantly improved in self-confidence and procedural proficiency from the pretest to posttest. There was no statistically significant difference between the two groups regarding performance, indicating that the 3D-printed model was as effective as the ready-made model. Satisfaction levels were high across both groups, with no significant differences noted.

Conclusions: The low-cost, 3D-printed endoscopy training model was found to be as effective as the high-cost, ready-made model in improving students' self-confidence and proficiency in nasopharyngoscopic velopharyngeal port assessment. This finding suggests that 3D-printed models can be a viable and cost-effective alternative for simulation-based education in speech-language pathology programs, particularly in resource-limited settings.
