The belief that breast hypesthesia is an expected consequence of reduction
mammaplasty is based on past reports that failed to objectively quantify br
east sensibility. Forty-five women undergoing reduction mammaplasty by one
plastic surgeon using a single operative technique were followed prospectiv
ely for change in breast sensation. Pressure threshold measurements were ta
ken preoperatively and at 2 and 6 weeks postoperatively, by using Semmes-We
instein monofilaments. Areas tested included the nipple, four points on the
areola, and four points 1 cm from the areola on the breast skin. The data
were nonparametric and were analyzed by using the Wilcoxon signed rank test
. For all areas tested, sensation significantly improved from preoperativel
y to 2 weeks (i.e., nipple: 33.1 versus 29.3, p < 0.0004) and again from 2
to 6 weeks (i.e., nipple: 29.3 versus 19.3, p < 0.002). Relief of chronic n
erve traction injury is conjectured as the reason for sensibility improveme
nt. Numb nipples persisted in 2 percent of breasts at 6 weeks.
