[Skull deformities as sequelae of unilateral mandibular dysbalance. 3. Studies of asymmetry based on frontal sections].

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.
