Osteonecrosis of the hyoid bone is an uncommon disease that has only been described occasionally in the literature.
We report 3 cases of osteonecrosis of the hyoid bone after radiation therapy for carcinoma at various sites in the head and neck region.
Imaging computed tomography (CT) scans were performed for all 3 cases and did aid in the diagnosis. In 1 case, a 201thallium scintigraphy and a bone scan (99mtechnetium-diphosphonate) were performed and this confirmed the diagnosis of osteoradionecrosis.
Osteoradionecrosis of the hyoid bone may be misdiagnosed as recurrent neoplasm. Although recurrent or persistent neoplastic disease must initially be ruled out, it is subsequently important to correctly identify osteonecrosis of the hyoid bone, because its surgical treatment is simple and the prognosis is good.
舌骨骨坏死是一种罕见疾病，在文献中仅有零星报道。
我们报告了3例头颈部不同部位癌放疗后发生舌骨骨坏死的病例。
对所有3例患者均进行了计算机断层扫描（CT），这有助于诊断。其中1例患者进行了铊-201闪烁扫描和骨扫描（锝-99m二膦酸盐），确诊为放射性骨坏死。
舌骨放射性骨坏死可能被误诊为肿瘤复发。虽然必须首先排除复发性或持续性肿瘤疾病，但随后正确识别舌骨骨坏死很重要，因为其手术治疗简单且预后良好。
