The reliability of the lipectomy procedure was confirmed in two studies. The first, Tumescent Technique, Tumescent Anesthesia & Microcannular Liposuction (2000) reported that tumescent liposuction is a reliable reduction mammoplasty procedure, which yields consistent results of size, appearance, and texture of the reduced-volume breasts.[32][33] The second study by Daniel Lanzer, Breast Reduction with Liposuction (2002), about a 250-woman cohort, reported that the application of tumescent liposuction, as the sole reduction-mammoplasty procedure, yielded consistent results wherein none of the patients had loose breast-skin envelopes, irregular breast-shape, permanent loss of sensation (either glandular, dermal, or of the NAC), scars, tissue necrosis, or infection.[34]
