目的：探讨下颌骨缺损之髂骨复合瓣(ICCFF)移植及"窗口"皮瓣观察移植骨块血运的临床应用的可行性。方法：采用5例下颌骨良性肿瘤术后缺损即期ICCFF修复，通过皮瓣血运情况判断髂骨块血运。结果：5例"窗口"皮瓣全部成活即髂骨块存活，外形满意。随诊1年，X线片上移植骨与周围骨组织类骨折样愈合，高度无明显改变。结论：一侧下颌骨大块缺损是ICCFF的最好的应用适应证。髂骨的自然曲度使得移植后的下颌外形及功能获得理想效果。"窗口"皮瓣可作为术后观察移植骨块血运，具有直观，简便等优点。%Objective :To observe the effects of iiiac crest composite free flap (ICCFF) in the reconstruction of mandibular defects. Methods:Mandibular defects were reconstructed with ICCFF in 5 cases. "Window flap" was used to monitor the blood supply of ICCFF. Follow-up was carried out for 1 year and the effects of reconstruction were evaluated by general observation and radiography. Results:Satisfactery face contour and bony healing of the grafts with the adjacent bone bed were observed in all the cases. Conclusion: ICCFF can be used to reconstruct large defects in mandible and the "window flap"can be used to moniter the blood supply of bone grafts.
