摘要
为积累国人体质资料和临床应用,作者观测了国人90个颅骨的180侧(男108侧,女72侧)内耳门的形态和径值。国人内耳门的形态可分为6种类型;长径为10.19mm,宽径为5.03mm;在性别和侧别上,存在显著性差异(P<0.05)。
Ninety Pairs of porus acusticus internus of the Chinese cranium (collected from Neimonggu, Tangshan and Hunan,China)are observed and measured, of which 54 pairs are male's ;36, female's. The results show that the forms of the porus acusticus internus can be classified into 8 types. The mean length is 10.19mm;the mean breadth is 5.03mm.The length and breadth of the porus acusticus internus differ greatly in different sex and side.
