Description
Summary:Background Distraction osteogenesis is a standard method for craniosynostosis. However, the technique using conventional devices still has some disadvantages, especially for anterior or posterior plagiocephaly with complex deformities. In the Nakajima’s angle-variable internal distraction (NAVID) system originally for maxillary surgeries, the cranial three-dimension (D) distractor with three dimensionally movable joint at the anterior arm has been developed recently in order to prevent the interference in the distraction process and excessive force. Case reports In this paper, we first reported two cases of anterior plagiocephaly, and one case of posterior plagiocephaly received distraction osteogenesis using new 3-D distractor in the NAVID system. In two cases of anterior plagiocephaly, the reshaping of supra-orbital bar in reference of simulating by the 3-D skull model was performed. In all cases, we fixed two paralleled 2-D distractors and a 3-D distractor in the upper frontal or parietal region. Conclusion Within the limitations of this study, we believe that the NAVID system is suitable for infant plagiocephaly due to the simple and small joint arm. Furthermore, the usage of the 3-D distractor would reduce the interference with 2-D distractors and easily lead to attainment of targeted distracting distance.
