Osteoradionecrosis (ORN) of the hyoid bone is a rare but reported complication of head and neck irradiation. Here we describe 2 cases in which carotid rupture was associated with hyoid ORN.
This study was conducted through a retrospective chart review and case reports of 2 patients.
Both patients had a history of radiation therapy for head and neck cancer; 1 patient had undergone previous surgical resection. Both patients had a history of painful swelling in the neck preceding presentation with hemorrhage. Acute hemorrhage was controlled in all patients using a combination of techniques including embolization, stent grafting, and vessel ligation.
ORN of the hyoid can be associated with life-threatening carotid rupture. In patients with a history of head and neck irradiation who present with painful swelling in the region of the hyoid, this entity should be considered. Early intervention may prevent subsequent rupture of the carotid artery and hemorrhage.
舌骨放射性骨坏死（ORN）是头颈部放疗后罕见但有报道的并发症。本文描述了 2 例与舌骨 ORN 相关的颈动脉破裂病例。
本研究通过回顾性病历分析和 2 例病例报告进行。
2 例患者均有头颈部癌症放疗史，1 例曾行手术切除。2 例患者均有颈部疼痛性肿胀史，随后出现出血。所有患者均采用栓塞、支架移植和血管结扎等联合技术控制急性出血。
舌骨 ORN 可并发危及生命的颈动脉破裂。对于有头颈部放疗史、出现舌骨区域疼痛性肿胀的患者，应考虑到这种情况。早期干预可能预防随后的颈动脉破裂和出血。
