What is ideal measurement of sternal notch to nipple?

Thanks for your question.  The "average" sternal notch to nipple distance is 21cm, but there is a wide range.  Most surgeons and patients would rather err on the nipple being slightly low than too high, since a high nipple can be a source of embarrassment in certain clothing.

Typically the sternal notch to nipple distance is between 20 and 23 cm, but it is a variable which is based on the individual's anatomy.

The textbook answer is somewhere between 19-21 cm.  However, after 10 years in practice doing mostly breast surgery, I can tell you that the measurement numbers are not very useful.  It is the relative proportions of a woman's chest and breasts that really matter, not an arbitrary measurement.  As a surgeon looking for a perfect aesthetic result, I would be much more likely to look at shape, volume, symmetry, projection, and appropriateness to the overall size and shape of the patient than I would to look at the sternal notch to nipple distance.  If you love the look of your breasts, then who cares about the measurement.  If you hate the look of your breast, it's probably not simply because the distance is 22cm and not 21 cm.I hope this helps!Dr. Robert Shenker MD FRCSC

There are no ideal measurements because each person is built differently and what might be right for one person is not for another.

Although most publications state that the ideal distance is 21 cm, this is merely a guideline affected by height, weight, body habitus, age, infra mammary fold position, etc, etc. ( I think you get the point there).  It really comes down to whether the nipple is sitting on top of the breast mound and does it show when wearing a bra or bathing suit.  Additionally circumareolar procedures are quite notorious for spreading scars.  Difficult to be more specific without photos.  I would recommend that you return to your surgeon and voice your concerns as I would ceratainly want to know of a concerned patient.  Best of luck.
