Outcome After Breast Reduction Considering Body Mass Index and Resection Amount.

BACKGROUND

It is presumed that breast reduction improves patients' quality of life and promotes weight loss. Preoperative body mass index (BMI) and the amount of breast tissue (breast reduction amount [BRA]) in proportion to the patient's body weight are important variables to affect the breast reduction outcome.

OBJECTIVE

This study was designed to evaluate the short and long-term effects of breast reduction from the perspective of BMI and BRA.

METHODS

One hundred fifty-seven consecutive patients were invited to participate in the study. All clinical information was recorded on a breast surgery form. Patients completed a standardized questionnaire preoperatively, at postoperative year 1, and after postoperative year 5. Patients were grouped according to their BMI as "normal weight" and "overweight" and according to BRA as "minor/moderate reductions" and "major reductions." The differences in the BMI values and the life scores were compared between the BMI and BRA groups.

RESULTS

Sixty-four patients were included in the study. Postoperative year 1 BMIs were significantly lower than both the preoperative BMIs and postoperative year 5+ BMIs. The year 1 BMI decrease in the major reduction group was higher than the decrease in the minor/moderate reduction group. The postoperative life scores of all subgroups were better than the preoperative life scores.

CONCLUSIONS

Reduction mammaplasty has a significant effect on short-term weight loss and the improvement in lifestyle. Patients tend to return to their original body weight in the long term. BRA is a significant variable in short-term weight loss, but neither BMI nor BRA has any other significant effect on the outcome in any time section.
