骨性外耳门的测量研究

MEASUREMENT OF EXTERNAL ACOUSTIC PORE ON SKULLS

所用材料为长春、通辽两地区出土成套的成人颅骨166个(男89,女77)。对外耳门纵径和横径、外耳道鼓室深、耳门蝶点径及耳门乳突径分别进行了测量,并计算外耳门指数。结果:所测量项目男性左右侧平均值分别为12.16±1.68mm、7.37±0.92mm、19.92±1.67mm、58.47±3.54mm、32.58±3.09mm;女性左右侧平均值分别为11.02±1.30mm、6.93±0.99mm、18.10±1.34mm、57.33±3.54mm、30.01±2.87mm。经统计学处理性差非常显著(P<0.01),而外耳门指数则无差异。同时本文还对耳门的形态进行了分型,为人类学的研究提供了资料。

The vertical diameter and the transverse diameter of the external acoustic pore, the depth of the meatus acusticus externus plus cavitas tympanica, the porion-sphenion distance and the porion-mastoideale distance were measured respectively, and the index of external acoustic pore was calculated. The samples used in this study were 166 (males 89, females 77) adult skulls in Chang Chun and Tong Liao Districts, Northeast China. The results showed: the mean values of above measurements were 12. 16±1. 68mm, 7. 37±0. 92mm,19. 92±1. 67mm, 58. 47±3. 54mm, 32. 58±3. 09mm in male and 11. 02±1. 30mm, 6. 93±0. 99mm, 18. 10±1. 34mm, 57. 33±3. 54mm, 30. 01±2. 87mm in female respectively. There was significant difference between the male and the female (P<0. 01) .while there was no difference in the index of external acoustic pore. Meanwhile, the shape of the external acoustic pore was divided into 3 types. This paper provides some useful data for the anthropological study of the Chinese.
