The embryologic origin of the parietal bone is membranous bone. Experimentally, membranous bone grafts, maintain its original size, structure with good osteo-integration contrary to endochondral bone autografted (ilium, rib or tibia). The morbidity of skull bone grafts is much less than other donor site of bone. In our study, between 1988 and 1992, autogenous split calvarial bone grafts were used in maxillo-facial reconstruction of seventy-one patients. We observed no major complication. Patient followup has been from 2 to 6 years and results are better than endochondral grafts (iliac crest, ribs, tibia). Parietal grafts bone have been used in the following case: nasal reconstruction, rehabilitation of defects in the floor of the orbit, maxilla grafts, correction of frontal depression and mandibular reconstruction.
顶骨的胚胎学起源是膜性骨。实验表明，与软骨内骨自体移植（髂骨、肋骨或胫骨）相反，膜性骨移植能保持其原始大小和结构，并具有良好的骨整合性。颅骨移植的发病率远低于其他骨供区。在我们的研究中，1988年至1992年间，71例患者在颌面重建中使用了自体颅骨劈开骨移植。我们未观察到重大并发症。患者随访时间为2至6年，结果优于软骨内移植（髂嵴、肋骨、胫骨）。顶骨移植已用于以下情况：鼻重建、眶底缺损修复、上颌骨移植、额部凹陷矫正和下颌骨重建。
