The reduction of oversized breasts by liposuction only (lipectomy) is indicated when a minor-to-moderate volume-reduction is required, and there is no breast ptosis to correct. However, in a 2001 study of 250 patients, nipple and breast elevation of between 3 cm and 15 cm was reported.[1] Further indications for lipectomy are presented by: (i) the woman who requires a large-volume reduction, and wants un-scarred, sensate breasts, yet will accept a degree of ptosis; (ii) the woman who requires a secondary mammoplasty to correct an asymmetric breast, by up to one brassière cup-size; and (iii) the girl affected by virginal breast hypertrophy, as a temporary procedure performed before the conclusion of her thelarche (the pubertal breast-growth phase), given the hypertrophy's high rate of recurrence.[citation needed]
