The aim of this retrospective study was to determine the pre- and postoperative symptoms among 170 women, who had modified Robbins reduction mammaplasties. The major part of the breast tissue was removed superiorly and laterally. The operations were carried out between January 1994 and April 1996. The journals were reviewed, and a questionnaire was sent to the patients. Ninety-one percent were returned. Many of the preoperative symptoms were significantly reduced in frequency post-operatively. Prior to operation, some of the patients had had symptoms that influenced their ability to manage their jobs and/or education, and 22% of the women took analgesics daily or several times weekly before surgery. After the operations the need for medicine was significantly reduced. A modified Robbins reduction mammaplasty significantly relieved many preoperative symptoms. The need for analgetics medicine was reduced, and the cosmetic results were good.
