The osteomyocutaneous iliac crest free flap is a reconstructive option for segmental mandibular or complex palatomaxillary defects. Familiarity with the radiographic appearance of free flaps such as the iliac crest is necessary for the postoperative evaluation of patients after mandibular, maxillary, or palatal reconstructions because it allows radiologists to properly monitor and interpret the appearance of the flap over time. This study presents a retrospective review of 5 patients who underwent palatomaxillary reconstruction with an iliac crest free flap at our institution. The imaging appearances of the 5 patients were analyzed to determine the key radiographic characteristics of a healthy and successful iliac crest free flap. Radiographic fluency with the imaging appearance of the iliac crest free flap, as well as the new anatomy of the region in the postoperative period, will allow for better interpretation of the flap appearance on imaging and will prevent false identification of tumor recurrence.
游离髂嵴骨肌皮瓣是下颌骨节段性或复杂的上颌-腭部缺损的重建选择。由于它可以使放射科医生随着时间的推移正确地监测和解释皮瓣的外观，因此熟悉游离皮瓣（如髂嵴）的影像学表现对于下颌骨、上颌骨或腭部重建术后患者的术后评估是必要的。本研究回顾性分析了 5 例在我院行游离髂嵴骨肌皮瓣行上颌-腭部重建的患者。分析了 5 例患者的影像学表现，以确定健康和成功的游离髂嵴皮瓣的关键影像学特征。对游离髂嵴皮瓣影像学表现以及术后区域新解剖结构的熟练掌握，将有助于更好地解读皮瓣的影像学表现，并防止对肿瘤复发的错误识别。
