Abstract：
Stylomandibular fusion is a poorly documented and rare complication of maxillofacial surgical procedures. This case report describes a patient presenting with stylomandibular false ankylosis following mandibular reconstruction. A 59-year-old female patient underwent segmental mandibular resection and reconstruction for a defect resulting from ameloblastoma surgery using an iliac crest free flap. A styloid fracture was detected postoperatively, and the patient was managed conservatively. In the third postoperative year, the patient presented with marked limitation of oral gape. A diagnosis of stylomandibular false ankylosis was made, and the patient underwent an ostectomy of the aberrant bone, with improved mouth opening. The abnormal union between the styloid process and the mandible is a previously unreported complication in the use of iliac crest free flaps. This case report emphasizes the importance of being vigilant for stylomandibular false ankylosis, especially when there is a restriction of oral aperture postoperatively following reconstructive procedures involving bone flaps.
摘要：
下颌关节融合术是颌面外科手术中记录较少且罕见的并发症。该病例报告描述了一名患者在下颌骨重建后表现出假性关节强直。一名59岁的女性患者使用a骨游离皮瓣对成纤维细胞瘤手术导致的缺损进行了节段性下颌骨切除和重建。术后发现茎突骨折，病人得到了保守的管理。在术后第三年，患者出现明显的口腔间隙限制。诊断为体下颌假性强直，病人接受了异常骨的切除，改善张嘴。茎突和下颌骨之间的异常结合是先前未报道的使用the骨游离皮瓣的并发症。该病例报告强调了对下颌关节假性强直保持警惕的重要性，特别是当涉及骨瓣的重建手术后，口腔孔径受到限制时。
