Presentation of complex laryngotracheal surgeries using CT-based 3D models and 3D printing: a technical note.

Introduction: Slide laryngotracheopexy for cricotracheal stenosis and extended partial laryngectomy combined with tracheopexy for T2-T3 glottic tumors represent novel, complex laryngotracheal surgeries requiring meticulous preoperative planning.

Methods: In addition to conventional diagnostic tools (imaging, endoscopy), digital/virtual 3D techniques along with 3D printing - also referred to as Additive Manufactoring (AM)- allow for the creation and application of CT-based virtual and 3D-printed models of the larynx and the trachea. These 3D technologies can facilitate surgical team preparation and provide an innovative approach to training on complex surgical solutions.

Discussion: This paper presents the digital workflow for three cases where patient-specific 3D laryngotracheal models were developed and successfully applied in surgical planning and training. These models serve as high-fidelity anatomical representations for surgical rehearsal, training, and patient communication, demonstrating their potential for broader clinical implementation.
