Observational analysis found improved airway patency in canine models with a novel 3D-printed splint, suggesting enhanced reconstructive outcomes.

All canines with a C5 mm tracheal substitute regained tracheal lumen patency after surgery, demonstrating the effectiveness of the splint.
The median survival time of the canines post-operation was 41 days, indicating a positive outcome for this reconstruction method.
Radiographic evaluation showed over 40% patency at four weeks, pointing to the splint's effectiveness in maintaining airway integrity.
Histological examination revealed excellent viability and extensive vascularization of the skin flaps, supporting its use in tracheal repairs.

Zheng et al. (2025) studied this question.
