The areas obtained by planimetry of parafrontal sections showed distinct asymmetry in the region of the cavitas nasi in the Beagles that had been operated. Although differences between the sides were also observed in the skulls of the control Beagles, they were very slight. There were no differences between the left and right sides in regard of the areas of the cavitas cerebri in either the operated or the control Beagles. In the operated skulls they are slightly larger than normal, but in the control animals they are within the physiological range of variation.
通过对额叶旁切片进行平面测量获得的区域显示，接受手术的比格犬鼻腔区域存在明显的不对称性。虽然在对照比格犬的颅骨中也观察到两侧存在差异，但差异非常微小。无论是接受手术的比格犬还是对照比格犬，其脑腔区域的左右两侧均无差异。在接受手术的颅骨中，它们比正常情况略大，但在对照动物中，它们处于生理变异范围内。
