Although we can consider that a certain degree of asymmetry is normal -both in the body and in the face- there are cases of true asymmetries which, in certain occasions, cause important disorders. The slight facial asymmetry is absolutely normal and it is normal to have one side of the face greater than the other, both wide and high, have a higher eyebrow, a lower eyelid, a somewhat deviated nose or lips, etc. These asymmetries are due to differences in the growth of the bony structures on each side and, sometimes, to the greater or lesser expressivity of each side of the face. Although rarely the degree of asymmetry is so important that it requires treatment, in rare cases it may be necessary to resort to surgery and, more frequently, we can obtain an adequate symmetry through the use of injectable fillers, fat grafts or facial implants. The asymmetry in the position of the eyebrows can be corrected by a unilateral lifting. The bodily asymmetries of low intensity are also normal. The differences in size of the two parts of the body are usually mild and only those that are of considerable importance cause alterations. One of the most serious causes of alteration of the body of young women is the asymmetry of the breasts (mammary asymmetry) that can reach such severe degrees that their correction requires a reduction of one breast and the placement of an implant in the other. . In the same way, the placement of implants of different sizes can compensate for the volume asymmetries of the breasts, buttocks or calves. Finally, liposculpture and fat grafts are very useful to equalize both sides of the body.
