Abstract

This study developed a novel digital workflow to fabricate a 3D printed hollow obturator for the prosthetic reconstruction of palatal fistula. It will provide cleft surgeons and therapists a choice for treating children with large palatal fistula before the appropriate age for surgical reconstruction. Laryngoscope, 133:1507-1512, 2023.
