Anatomical and functional rehabilitation after total bilateral maxillectomy using a custom-made bone-anchored titanium prosthesis

摘要

Surgical reconstruction after a total maxillectomy remains challenging. The standard treatment is the microvascular free flap. In cases of surgical contraindication, oral rehabilitation is usually performed with a palatal obturator prosthesis (PAP). Acceptable anatomical and functional outcomes in terms of speech, mastication, aesthetic appearance, stability, and comfort are not often achieved with a PAP. This technical note describes a technique for reconstruction after total bilateral maxillectomy involving the implantation of a custom-made bone-anchored titanium prosthesis obtained by 3D printing. Good functional and anatomical outcomes were achieved with this technique. It combines the advantages of the obturator prosthesis (short duration of surgery and hospitalization, low morbidity) and free flap (aesthetic/anatomical reconstruction and irremovable comfortable functional rehabilitation). This technique constitutes a new therapeutic alternative for the restoration of large defects after total maxillectomy when free flaps are contraindicated.
