PURPOSE
A variety of templates are being used for mandible reconstruction with free flaps. We describe a simple and cost effective method using a 'K' wire template for the central segment reconstruction of the mandible with free fibula flap.
MATERIALS AND METHODS
Over a period of 5 years from January 2005 to December 2009, there were a total of 386 mandible reconstructions with free fibula flaps of which 262 were central segment reconstructions. The number of osteotomies varied from 1 to 2 depending up on the length of the bone reconstructed. 'V' shaped closing wedge osteotomies were done and the segments were aligned with mini plates. In all the cases a 'K' wire was used in forming a template for the neo mandible from the resected specimen.
RESULTS
The bone union was good in all the cases as determined by the orthopantomograms taken at the third month follow up. The most common complication was prognathism of the neo mandible.
CONCLUSION
'K' wire template is a simple and cost effective device to design the shape of the neo mandible with less osteotomies and align the osteotomised bone segments in an angle that gives a near normal shape.
目的
多种模板正被用于游离皮瓣下颌骨重建。我们描述一种简单且经济有效的方法，即使用克氏针模板，通过游离腓骨瓣进行下颌骨中央节段重建。
材料与方法
从2005年1月至2009年12月的5年期间，共有386例采用游离腓骨瓣进行下颌骨重建，其中262例为中央节段重建。截骨数量根据重建骨的长度从1至2不等。进行“V”形闭合楔形截骨，并使用微型钢板使各节段对齐。在所有病例中，均使用一根克氏针根据切除标本为新下颌骨制作模板。
结果
通过术后3个月随访时拍摄的曲面断层片确定，所有病例骨愈合良好。最常见的并发症是新下颌骨前突。
结论
克氏针模板是一种简单且经济有效的装置，用于设计新下颌骨形状，减少截骨数量，并以接近正常形状的角度对齐截骨后的骨段。
