Abstract
Radical maxillectomy frequently leads to extended defects in hard and soft tissues that result in a connection between the oral cavities and orbit. If the defect cannot be surgically reconstructed, a combination prosthesis may be necessary to remedy dysfunction in patient function, comfort, esthetics. For minor defects, enlargement of the base of the intra oral prosthesis is generally sufficient. Resections that affect more than one third of the maxilla usually require an intra oral and an extra oral prosthesis that could be assembled and retained in the patient. This clinical report describes a technique of prosthetic rehabilitation of midfacial defect with a silicone orbital prosthesis and intra oral obturator that are retained by magnets. Key words:Combination Prosthesis, Silicone Prosthesis, Magnets, obturators.
Highlights
Head and neck cancer treatment frequently leaves the patient with some facial deformity due to extensive muscle and bone loss which, in turn, can cause the patient to become depressed and isolated [1]

Large defects that result from cancer treatment rarely are rehabilitated by surgical reconstruction alone; they usually require a facial prosthesis to restore function and appearance [2]
Summary
Head and neck cancer treatment frequently leaves the patient with some facial deformity due to extensive muscle and bone loss which, in turn, can cause the patient to become depressed and isolated [1]. Marunick et al [3] classified midfacial defects into 2 major categories: midline midfacial defects, which include the nose and/or upper lip; and lateral defects, which include the cheek and orbital contents. Maxillofacial prostheses have the advantage of improving the patient’s appearance and enabling early rehabilitation These prostheses make it possible to inspect the affected area, shorten surgery and hospitalization time, lower treatment cost, and allow the patient to be psychosocially re-integrated more quickly. Retention of the prosthesis is a difficult problem because of its size and weight Securing it in place can be a formidable task [1]. This clinical report describes a technique of prosthetic rehabilitation of midfacial defect with a silicone orbital prosthesis and intra oral obturator that are retained by magnets
