Abstract:
Breast reduction is one of the most commonly performed plastic surgery procedures, and pedicle deepithelialization remains a time-consuming step of the operation. This is especially true when using an inferior pedicle. We present a novel technique of intradermal infiltration of the breast pedicle with local anesthetic to facilitate efficient, bloodless deepithelialization. The senior author uses a 20-ml syringe to inject 0.25% lidocaine and 1:400,000 epinephrine just beneath the epidermis of the breast pedicle to create a series of wheals. Approximately 20 ml of local anesthetic is used per pedicle. After injection of local anesthetic, the breast pedicle is deepithelialized in less than 3 minutes. The plane is bloodless, allowing improved visualization secondary to the epinephrine-induced hemostasis. The senior author has had only one case of nipple necrosis in 20 years of experience. Intradermal infiltration of local anesthetic with epinephrine hydrodissects between the epidermis and dermis and provides hemostasis to facilitate rapid deepithelialization.
