Thirty-two consecutive cranial computed tomographic (CT) scans in normal infants ranging from 1 day to 3 years of age were evaluated for asymmetry of the temporal lobes as evidenced by differences in the size of the sylvian fissures. The left sylvian fissure was larger than the right in 23 of the 32 cases, which was statistically significant (p less than 0.0001). In five other cases the two sides were equal; in the four remaining cases, the right side was larger than the left. The results show that asymmetry of the temporal lobes can be demonstrated in vivo even at birth and that this asymmetry is a normal developmental difference between the two hemispheres and not secondary to an acquired abnormality.
对32例年龄从1天到3岁的正常婴儿进行了连续的头颅计算机断层扫描（CT），以评估颞叶的不对称性，这可通过大脑外侧裂大小的差异来证明。32例中有23例左侧大脑外侧裂大于右侧，具有统计学意义（p小于0.0001）。另外5例两侧相等；其余4例右侧大于左侧。结果表明，即使在出生时，颞叶的不对称性也可在活体中得到证实，并且这种不对称是两个半球之间正常的发育差异，而非继发于后天异常。
