Breast reduction surgery has been used for the purpose of obtaining a natural cone shape for the breast, minimizing scars, and maintaining breast physiology. An importan factor influencing the selection of the type of procedure was the ease of predicting the eventual size of the breast moun and the final location of the nipple-aredlar complex, Several variations of the Round Block periareolar mammaplaty (Benelli) were described, but not enough to solve the problems of mound flattening and early ptosis. The thesis is set forth that:(1) use a circumareolar incision ot minimizs the scar,(2) adopt the central breast pedicle to preserve the physiology and make significant resection, and(3) introdue the self-implant concept to produe conical shape and prevent ealry ptosis, also predict the eventual size of breast easily. A personal series of 44 consecutive case(88 breasts) operated on from 1994 through 1996 is reviewed. The amount excised ranged from 150g-1200g per breast(mean 423g). The majority of patients were pleased with their breast size, shape and especially scars. There were few complications; one skin flap necrosis (1/88), one partial nipple-areolar necrosis(1/88) and 12 sensory disturbances of nipple-areolar complex(12/88). This series proves that circumareolar reduction mammaplasty with self-implant technique cna be used safely in significant resections for breast hypertrophy, respecting both aesthetic and functional aspects.
