Extended latissimus dorsi musculocutaneous flap for breast reconstruction: experience in Oriental patients, , ,

Unilateral breast reconstruction with an extended latissimus dorsi musculocutaneous flap was carried out for 12 women in the National Cheng Kung University Hospital. Eleven patients acquired a good or fair result cosmetically. We analysed the net weight of the flap as well as various anthropometric data to see what effect they have on the final aesthetic outcome. The weight of the flap ranged from 180 to 610 g, and the resected specimen weighed from 160 to 635 g. The flap weight was equivalent to 61%–113% of the specimen weight. A satisfactory result could be achieved when the bulk of the flap attained 70% of the mass resected. We also observed that the aesthetic quality is better when the breast is less ptotic. All of the muscle transfers survived completely without any flap loss. The only complications included one minor wound edge slough and another modest seroma formation at the donor site. This reconstructive method is a viable option for young women with small or medium-sized breasts who anticipate pregnancy in the future. It is especially advisable in Oriental society, since the breast size of the patients is generally smaller and the donor scar is hidden, given the hypertrophic tendency of the lower abdominal scar in Asian people undergoing TRAM flap reconstruction.
