摘要
目的调查黄金分割律在成人舌系带上的体现并分析其临床意义。方法选取2008—2009年昆明市延安医院体检人员15392名(男8719名,女6673名),测量舌系带各段的长度:A段为口底下颌骨黏膜转折处至舌下肉阜处的颌下腺导管口,B段为舌下肉阜处的颌下腺导管口至舌系带转折点,C段为舌系带转折点至舌系带与舌腹之附丽顶点。对所得数据进行统计分析。结果 15392名体检人员中A/(B+C)≈0.5共10576名,所占比例为68.71%;男性中A/(B+C)≈0.5为6004名,比例为68.86%;女性中A/(B+C)≈0.5为4572名,比例为68.51%,男女间差异无统计学意义(χ2=0.21,P>0.05)。20～40岁,>40～60岁,>60岁体检人员中A/(B+C)≈0.5所占比例分别为68.55%(5026/7332)、65.15%(4103/6298)、82.12%(1447/1726),三者间差异均有统计学意义(均P<0.05)。结论舌下肉阜处的颌下腺导管口位于舌系带前1/3分界点具有较显著的代表性,符合人体中线黄金分割律。
Objective To investigate exemplification of Golden Section at adult tongue tie, and analyze the clinical significance. Methods The tongue tie was divided into three sections ： section A was the distance from the turning point of the inside mucosal of mandible to the submandibular duct month of sublingual mucosa; section B was the distance from the submandibular duct mouth of sublingual mucosa to the turning point of tongue tie; section C was the distance from the turning point of tongue tie to the reattachment peak point of tongue belly by tongue tie. Measure and calculate the ratio of A / B＋C by investigating 15 392 cases. Results When the ratio of A / B＋C was approximately 0.5, 10576 cases were detected, including 6004 males and 4572 females, the rate was 68.71%. The rate was 68.86% for males and the rate was 68.51% for females, no significant difference between males and females （ χ^2 = 0.21, P 〉 0.05 ） . The rates of the three age groups were 68.55% （ 5026 / 7332 ）, 65.15 % （4103 / 6298 ） and 82.12% （ 1447 / 1726 ） respectively, there being significant differences among the three（P 〈 0.05）. Conclusion Significant representation is when the submandibular duct mouth of sublingual mucosa is situated the first 1 / 3 cut-off point of tongue tie, being in accordance with Golden Section in body midline.
