Surgery has become an invaluable adjunct to orthodontic therapy. However, before embarking on surgical procedures, particularly in growing individuals, it is necessary to appraise each case carefully to determine whether the dentofacial dysplasias can be corrected by orthodontic or orthopedic means. It is possible by the use of investigative procedures to determine the extent and severity of malocclusions and any associated dentofacial dysplasias. General growth rates, increments, and directions can be predicted with some degree of accuracy. Likewise, favorable and unfavorable growth patterns can usually be identified. However, there are those cases in which, for reasons unknown, the growth patterns do not follow the usual trends. These cases often do not respond satisfactorily to treatment because of bizarre or unanticipated growth patterns. Science, unfortunately, has not progressed sufficiently so that such patterns can be identified ahead of time. Until the secrets of such growth patterns are uncovered, treatment procedures, response to the therapy, and growth predictions, of necessity, must be based on average growth trends.
外科手术已成为正畸治疗中一项极为重要的辅助手段。然而，在开展外科手术之前，尤其是对于仍在生长发育的个体，必须对每个病例进行仔细评估，以确定牙颌面发育异常是否可以通过正畸或矫形手段得到矫正。通过采用一些检查程序，能够确定错牙合畸形的程度和严重程度以及任何相关的牙颌面发育异常。一般的生长速率、生长增量和生长方向能够在一定程度上准确预测。同样，通常也能够识别出有利和不利的生长模式。然而，存在一些病例，由于不明原因，其生长模式并不遵循通常的趋势。由于生长模式怪异或出人意料，这些病例往往对治疗反应不佳。遗憾的是，科学尚未取得足够的进展，以至于无法提前识别出此类模式。在揭开此类生长模式的奥秘之前，治疗程序、对治疗的反应以及生长预测必然要基于平均生长趋势。
