There are limits to the amount of local anaesthetic that can be used safely in one operation. If large amounts of fat need to be removed, more than one session may be necessary. The removal of five litres of fat is considered to be the upper limit for tumescent liposcupture. However, for a heavier person, more can be removed in stages. Too much or too little fat can be removed, or it may be uneven, resulting in a minor contour defect such as rippling or dimpling. This can be corrected with a lesser operation to “fine tune” the result.
