To report on 2 cases of late bony regrowth with clinically apparent proptosis after deep lateral orbital decompression for thyroid orbitopathy.
A retrospective review of 2 cases identified by the authors as having late bony regrowth. The authors review the clinical, historical, radiologic, and anatomical findings and discuss the significance thereof.
Bony regrowth with bowing toward the middle cranial fossa is observed at postoperative month 8 in the first case. Cortical bone and marrow was observed to regrow at 2 years postoperatively in the second case. Both patients underwent successful repeat deep lateral orbital decompression with resolution of proptosis and clinical symptoms.
Late bony regrowth should be considered as a possible cause of recurrent proptosis after orbital decompression in thyroid eye disease.
报告2例甲状腺眼病患者在进行眼眶外侧深部减压术后出现晚期骨再生并伴有明显眼球突出的病例。
对作者认定的2例晚期骨再生病例进行回顾性研究。作者回顾了临床、病史、影像学和解剖学检查结果，并讨论了其意义。
第一例患者在术后第8个月观察到骨向中颅窝方向生长。第二例患者在术后2年观察到皮质骨和骨髓再生。两名患者均成功接受了再次眼眶外侧深部减压手术，眼球突出和临床症状均得到缓解。
晚期骨再生应被视为甲状腺眼病眼眶减压术后复发性眼球突出的可能原因。
