Prediction of cosmetic outcome following conservative breast surgery using breast volume measurements.

This study was undertaken to examine the feasibility of breast volume estimation as a predictor of cosmetic outcome. We looked at the cosmetic result of conservative surgery related to the percentage of breast tissue removed. The breast tissue excised was calculated by comparing the breast volume, calculated from the mammogram, and the specimen volume. A total of 24 patients were recalled to a special clinic and were assessed for their cosmetic result by the clinician, independent observer and the patient. The assessment was based on a scale of 1 to 4 (poor to excellent). Our results show that if less than 20% of the breast was removed, all assessors felt that the cosmetic result was at least fair. If more than 20% of the breast was removed, the cosmetic score was poor as assessed by the clinician and independent observer. When excision of greater than 20% of breast tissue is anticipated, then a breast reconstruction procedure should be considered, if cosmetic outcome is to be enhanced.
