Simulated slide tracheoplasty for congenital tracheal stenosis using three-dimensional printed models

Study evaluates 3D-printed tracheal models for preoperative planning in slide tracheoplasty for congenital tracheal stenosis. Ten patients underwent simulated surgery using CT-derived hollow models, achieving good airway patency postoperatively. Models proved valuable for surgical planning and multidisciplinary communication despite no significant difference in clinical outcomes versus historical controls.
