Prosthetic rehabilitation of large midfacial defects.
Advanced tumors of the midfacial region often require removal of the nose, upper lip, portions of the maxilla, and other adjacent structures. When the resultant defects do not lend themselves to surgical reconstruction, prosthetic appliances may be used successfully to restore the functions of speech and swallowing to near-normal levels. The degree of success depends upon the nature of the previous treatment, the existing surgical defect, and the adaptability of the patient. The most important anatomical consideration is the form and amount of the remaining maxilla. Recent advances in the development of the polyurethanes have resulted in lighter, more flexible, and, therefore, better tolerated prostheses. Close cooperation between the surgeon and the prosthodontist is necessary if successful rehabilitation of these patients is to be achieved.
