Cleft Palate J. 1978 Jan;15(1):44-8.
A method is described for rapidly measuring the surface area of the palate by adapting a piece of soft plastic to a model of the upper jaw using a vacuum moulding technique. Tests with a hemisphere of known surface area showed the method to be consistent and to have a low degree of systematic error. When measuring models with unrepaired cleft palates, the error was found to be 2.1 per cent (compared with 3 per cent using stereophotogrammetry) but 7.1 percent when measuring intact palates. Because of the consistency of the method, the true palatal area could be calculated from the measured area by the use of a multiplying factor. These findings are described, and the application of the technique to the pretreatment assessment of cleft cases is illustrated by showing that, in a series of 30 cleft palate and 30 normal infants, a tissue deficiency of 16.8 per cent existed in the cleft subjects at birth.
本文描述了一种通过使用真空成型技术将一块软塑料适配到上颌模型上来快速测量腭表面积的方法。对已知表面积的半球体进行测试表明，该方法具有一致性且系统误差程度较低。在测量未修复腭裂的模型时，发现误差为2.1%（立体摄影测量法的误差为3%），但测量完整腭时误差为7.1%。由于该方法具有一致性，可通过使用一个乘数因子从测量面积计算出真正的腭面积。本文描述了这些发现，并通过显示在一系列30例腭裂婴儿和30例正常婴儿中，腭裂患儿出生时存在16.8%的组织缺损，来说明该技术在腭裂病例术前评估中的应用。
