The 3D Printing of the Paralyzed Vocal Fold: Added Value in Injection Laryngoplasty



      Three-dimensional (3D) printing has had numerous applications in various disciplines, especially otolaryngology. We report the first case of a high-fidelity 3D-printed model of the vocal cords of a patient with unilateral vocal cord paralysis in need of injection laryngoplasty.


      A case report was carried out.


      A tailored 3D-printed anatomically precise models for injection laryngoplasty has the potential to enhance preoperative planning, resident teaching, and patient education.


      A 3D printing model of the paralyzed vocal cord has an added value in the preoperative assessment of patients undergoing injection laryngoplasty.
