The long-term fate of outer table calvarial bone has not been previously well established in terms of graft resorption and resultant contour in the face. A 4-year experience is presented with an emphasis on these areas. Eight hundred fifty grafts were placed in the face on 170 patients during this study period. A subgroup consisting of the nasal region was selected for a detailed analysis, since this complex could be readily evaluated, and the results have paralleled the remaining group. Although partial resorption is seen at most sites, ranging from insignificant to 30%, excellent contour has been achieved throughout the face and maintained in all but a few cases. The areas of maximum resorption and contour change were seen at the nasal dorsum and lateral posterior mandible.
就移植骨吸收情况及面部最终轮廓而言，此前尚未明确颅骨外板的长期转归情况。本文介绍了一项为期4年的研究，重点关注这些方面。在本研究期间，对170例患者的面部进行了850次移植。选择鼻区作为一个亚组进行详细分析，因为该区域易于评估，且结果与其他组相似。尽管在大多数部位都可见到部分吸收，吸收程度从微不足道到30%不等，但整个面部均获得了良好的轮廓，除少数病例外轮廓得以维持。最大吸收和轮廓改变区域见于鼻背和下颌骨后外侧。
