The relationship of angle SNA and SNB to angle SN-FH was determined by evaluating 106 teleradiographs. The correlation of the small SN-FH angle with the large SNA/SNB angle was statistically significant and vice versa. The normal range for SNA/SNB was determined by classifying SN-FH values. The use of these relations for the preoperative planning of orthognathic surgery was demonstrated in two clinical cases.
通过评估106张远距离X线片确定了SNA角和SNB角与SN-FH角的关系。小SN-FH角与大SNA/SNB角之间的相关性具有统计学意义，反之亦然。通过对SN-FH值进行分类确定了SNA/SNB的正常范围。在两个临床病例中展示了这些关系在正颌外科手术术前规划中的应用。
