Abstract:
Objective(s):
To assess the impact of a novel 3D-printed simulation model with Brainlab Image Guidance on enhancing otolaryngology residents' skills and confidence in performing Transcervical Intralaryngeal Injection (TII) compared to conventional training methods.
Methods:
Utilizing a 3D-printed larynx model derived from CT scans, this study involved sixteen otolaryngology residents divided into two groups for TII training: one with Brainlab Image Guidance (LMIG) and the other without (LM). Pre- and post-training evaluations measured participants' confidence while the Brainlab system measured the accuracy of their needle placements.
Results:
After training, participants exhibited a significant increase in confidence, with an average rise from 1.56 to 2.75 on a 5-point scale. The LMIG group outperformed the LM group in accuracy, achieving statistically significant reductions in target distances after training (3.5 mm right, 3.6 mm left). The LMIG also demonstrated a significantly greater increase in procedural confidence over the LM group after training.
Conclusion:
The TII laryngeal model with Brainlab Image Guidance significantly improves procedural confidence and accuracy among otolaryngology residents, signifying potential advantage over a more simplistic training approache. The model’s realistic tactile and live instrument positioning feedback differentiate it as useful tool for residency training programs, aiming to refine surgical skills in a controlled, risk-free environment.
