Early complications include infection and hematoma (blood outside the vascular system); late complications include an unsatisfactory breast-volume reduction that might require either surgical or liposuction revision. As with other liposuction procedures, the final result of a liposuction-only breast reduction becomes evident at 6-months post-operative; although the edema usually subsides at 2–3 weeks post-operative. To date, no incidence of tissue necrosis has been reported; likewise, there have been few reports of lessened nipple sensation.
