Abstract

This article reviews the prosthodontic and laboratory steps in the fabrication of a custom brachytherapy appliance. This technique is described through the treatment of a patient with recurrent orbital rhabdomyosarcoma. After a non–eyelid-sparing orbital exenteration of a 7-year-old boy, an impression of the orbital defect was captured to fabricate a custom brachytherapy appliance with mock catheters. One week later, the prosthesis was placed in the orbit, and the device was loaded with radiation catheters to deliver targeted radiation. The prosthesis was secured with Velcro straps fitted into slots made in the prosthesis and wrapped around the back of the patient's head. Brachytherapy appliances have been used to provide effective therapy for patients receiving care at Memorial Sloan Kettering Cancer Center.
