ABSTRACT
For patients with head and neck cancer requiring a maxillectomy, obturator prostheses help with quality of life. These patients routinely require adjuvant oncologic treatments with significant adverse effects. Treatment sequelae can leave patients with difficulty speaking and swallowing, reduced salivary function, reduction in maximal incisal opening, and at risk of osteoradionecrosis. A 55-year-old African-American woman presented with significant trismus and reduction in maximal incisal opening after treatment for squamous cell carcinoma of the left maxillary sinus. She had received a left total maxillectomy with adjuvant chemotherapy and radiation treatments. With her reduced opening, she was no longer able to insert her interim obturator prosthesis, which caused difficulty speaking and nasal regurgitation. A cone beam computed tomography scan was made of the patient's maxillectomy defect. From the Digital Imaging and Communications in Medicine file, a definitive cast was 3-dimensionally printed to fabricate a flexible silicone obturator prosthesis. This treatment has allowed the patient to return to a functional quality of life and could help other patients in similar situations.
