ABSTRACT
Radiation therapy for the treatment of head and neck skin cancer poses challenges because of the inherently uneven tissue topography of the face and the need to protect surrounding unaffected tissues. The use of a customized radiation shield that combines tissue-equivalent bolus material with protective material addresses these issues. This article describes a technique using rapid prototyping to design and fabricate an extraoral radiation shield. This innovative application provides an expedient, standardized approach for delivering radiotherapy to the face, which is not only more comfortable for the patient, but allows more precise treatment delivery.

The immediate prosthetic rehabilitation of a patient with erosive cutaneous cytomegalovirus (CMV) is presented. Although CMV is a major cause of morbidity and mortality in immunocompromised patients, skin lesions are rarely discussed in the literature. Recognition of the susceptibility of medically compromised patients to infections that can cause extraoral and intraoral deformity is essential to prevention, early diagnosis, and prompt intervention of a life-threatening destructive debilitation. A method for rapidly fabricating a nasal prosthesis is described, and the importance of prompt esthetic and psychological rehabilitation is reviewed.

BACKGROUND: Primary bone sarcomas arising in osseous structures of the head and neck are rare. These tumors are often incompletely resected and treated with radiotherapy for local control. METHODS: We report a case of a 9-year-old girl with a maxillary Ewing's sarcoma. This patient was successfully treated with neoadjuvant chemotherapy followed by surgical resection and prosthetic reconstruction of the primary site. The surgical approach that was used consisted of a subtotal maxillectomy by means of a facial degloving approach, sparing the orbital contents and the inferior orbital rim and orbital floor. RESULTS: This approach produced excellent cosmetic, functional, and oncologic outcome. The patient remains without evidence of disease recurrence more than 4 years after surgery. CONCLUSIONS: This case illustrates a novel surgical approach to the resection of a maxillary Ewing's sarcoma and highlights the need for a multidisciplinary team approach to the management of head and neck sarcomas in children.
