Unilateral gynecomastia is where one male breast is normal, and the other has developed more like a female breast with excess breast tissue and fat. Asymmetrical gynecomastia is where both the male breasts are enlarged but one more so than the other.
Gynecomastia breast asymmetry is a very common condition affecting many San Francisco Bay Area men but in varying degrees. In some cases, the condition is minor and depending on the man, correction is not necessary. For others, an experienced cosmetic plastic surgeon that specializes in gynecomastia surgery will be sought out to even out the chest as much as possible.
Some male breast reduction patients are concerned after surgery as they may see minor asymmetry of their chest. This is not unusual, and most likely due to accumulation of fluid or trauma from the surgery and usually will resolve itself in a few weeks.
