The fibular free flap (FFF) is commonly used for head and neck bony reconstruction. Ossification of the vascular pedicle has been reported but is an uncommon complication of this procedure. Ossification of the pedicle with FDG avidity has not been identified in the literature. Here we present a case of FDG avid free flap ossification seen on PET/CT imaging in a patient who developed trismus after fibular free flap reconstruction of a maxillary defect for a primary squamous cell carcinoma of the palate. The FDG avidity of the free flap ossification and trismus were both concerning for recurrent squamous cell carcinoma.
游离腓骨皮瓣（FFF）常用于头颈部骨重建。血管蒂骨化已被报道，但这是该手术的一种罕见并发症。文献中尚未报道 FDG 摄取活性的蒂骨化。在此，我们报告 1 例 FDG 摄取活性游离皮瓣骨化病例，该患者因硬腭原发性鳞状细胞癌行游离腓骨皮瓣修复上颌骨缺损后出现牙关紧闭，在 PET/CT 成像上可见。游离皮瓣骨化和牙关紧闭的 FDG 摄取活性均提示复发性鳞状细胞癌。
