Maxillofacial prosthetics is among the foremost rapidly growing areas of dentistry. It has become a key area, especially when it involves rehabilitation of postsurgical cases. 1-5% of oral lesions are malignant tumors that commonly affect the hard and soft palate and the gingiva. Squamous cell carcinoma accounts for 60% of the tumors that affect these areas. Most of those carcinomas are diagnosed very late i.e., when there is bone invasion. Treatment modalities of choice for removal of SCC are: alveolectomy, palatectomy or maxillectomy which could either be partial or total resection. The rehabilitation of such patients may be a daunting task. Rehabilitating patients with maxillofacial defects are among the foremost difficult therapies of the stomatognathic system and requires a multidisciplinary approach including surgery, radio/chemotherapy, phonetic rehabilitation, physiotherapy and prosthetic treatment. The defect/deformity characteristics, the number of teeth present and the amount of supporting structures determine the management of maxillary defects. Unfavorable characteristics of the defect can negatively affect the prosthetic management and treatment outcome. Good prognosis of the prosthesis requires adequate retention, light in weight and has to be comfortable to the patient and the surrounding tissues holding it. This article describes a case of a rhino-oral defect (Aramany class VI resection) whereby an acrylic hollow bulb obturator and an acrylic nasal prosthesis attached to spectacle were used for case rehabilitation.
