“…12 Considering the unconventional location of the osteochondroma in our case and the necessity of en bloc resection to prevent recurrence, we applied 3D-printing technology to assist in the surgical planning for its transoral resection. 1,2 The role of 3D-printing applications in the ENT field is emerging, including building auricular reconstruction frameworks, treating severe tracheomalacia, reconstructing complex tracheal, creating patient-specific mandible templates, performing endoscopic sinus or skull base surgeries, and even evaluating prenatal congenital airway obstruction.
