This study has provided baseline data of a quantitative neurophysiological appraisal of normal breast sensibility using our current understanding of cutaneous mechanoreceptive function. Test variables, including pressure, low- and high-frequency vibration, static and moving two-point discrimination, temperature, nipple erectibility, and pain, were evaluated in 11 normal volunteers using different coordinates over the nipple, areola, and body of the breast. Definite patterns were established so that the breast could be subdivided into distinct cutaneous areas with differing mechanoreceptive characteristics. The future aim is to broaden the scope of this study with preoperative evaluations in our clinical patients so that appropriate recommendations for future reconstructive breast procedures can be made.
