Partial rhinectomy is a challenge for most maxillofacial prosthodontists, as retention of the prosthesis is a major issue to overcome. The scenario becomes even more difficult when there is an intra-oral defect. This article describes the fabrication of a removable silicone nasal prosthesis and removable PMMA intra-oral obturator prosthesis to rehabilitate a patient following partial rhinectomy with associated loss of premaxilla. The retention of removable intra-oral and extra-oral prosthesis was achieved partially from anatomical undercuts and further enhanced byrare earth magnets placed between both prostheses. An acrylic framework was fabricated and placed inside to provide rigidity to the nasal part of the prosthesis. A customized method of making impressions using a modified syringe tube to mold the inner surface of the nasal defect is described. The obturator function scale (OFS) questionnaire was used to measure the patient’s satisfaction with the obturator. After insertion of the prosthesis, there was an overall improvement in the obturator function scale(OFS) of the patient.
Relevance for Patients: This case report documents the rehabilitation of a patient following partial rhinectomy and associated loss of premaxilla with customized intra-oral obturator prosthesis and a removable silicone nasal prosthesis. The successful outcome of this case shows that for people with similar orofacial defects, these prostheses are a good option to achieve acceptable aesthetics, speech and function.
