The cephalometric measurement of the face in terms of aesthetics can be difficult and misleading due to the variability of the intra-cranial reference lines according to diversity of head posture. Natural head position (NHP) has been proposed as a preferred reference position for assessing facial morphology. Even though natural head position is more proper and valid, it is still abandoned by reasons of time-consumption and additional and necessary complex equipment. Hence, we developed a modified level laser approach to acquire the natural head position. This method was a simple and straightforward technique which may be of value as and adjunct to routine orthognathic planning.
由于头部姿势的多样性导致颅内参考线存在变异性，从美学角度对面部进行头影测量可能既困难又容易产生误导。自然头位（NHP）已被提议作为评估面部形态的首选参考位置。尽管自然头位更合适且有效，但由于耗时以及需要额外的复杂设备，它仍然被弃用。因此，我们开发了一种改良的水平激光方法来获取自然头位。该方法是一种简单直接的技术，作为常规正颌手术规划的辅助手段可能具有价值。
