    Abstract:
    BACKGROUND: Osteoradionecrosis (ORN) is a well-known complication following irradiation of head and neck malignancies. ORN commonly occurs in the mandible but is rarely reported in the hyoid bone. CASE PRESENTATION: A 76-year-old female with a history of oropharyngeal squamous cell carcinoma presented with pharyngocutaneous fistula 14 years after primary chemoradiation. Imaging showed necrosis of the hyoid bone. She underwent excision of the hyoid to rule out malignancy. Pathology was negative for carcinoma, but did show extensive fragmentation and bony necrosis consistent with ORN. The patient's clinical course, surgical treatment, and management considerations are discussed here. CONCLUSIONS: Hyoid ORN should remain in the differential during diagnostic workup of previously irradiated head and neck cancer patients. The presentation of a pharyngocutaneous fistula should prompt workup to rule out malignancy before assigning a diagnosis of ORN.
