[Reconstruction of the mandible after loss of the middle segment due to an odontogenic myxoma].

In an 18-year-old boy, the middle segment of the mandible was removed because of a locally aggressive tumour. The reconstruction became infected and was lost, resulting in 2 separately-moving mandible parts and oral disability. For the second reconstruction, skeletal fixation with osteosynthesis plates, dental fixation with a stabilization frame and intermaxillary fixation were used.

A novel digital workflow to manufacture personalized three-dimensional-printed hollow surgical obturators after maxillectomy.

Partial or complete resection of the maxilla during tumour surgery causes oronasal defects, leading to oral-maxillofacial dysfunction, for which the surgical obturator (SO) is an important treatment option. Traditional manufacturing of SOs is complex, time-consuming, and often results in inadequate fit and function. This technical note describes a novel digital workflow to design and manufacture a three-dimensional (3D)-printed hollow SO.
