GUTHRIE, Jr., M.D. From the Divisions of Plastic Surgery, The New York Hospital-Cornell The Memorial Sloan-Kettering Cancer Center Medical Center and A PRINCIPAL concern in both reduction mammaplasty and dermal mastopexy has been to find a safe, suitable and technically easy method of transposing the nipple to its new bed while maintaining viability and normal sensation and obtaining a cosmetically acceptable result. The standard method for nipple transposition is that of Skoog (1963) and Strombeck (1960) where the nipple is carried on a transverse de-epithelialised, bipedicle flap, which maintains good nipple sensation and viability. We have found that tension on nipples thus transposed may be excessive, leading to areolar distortion post-operatively Several authors have addressed themselves with nipple inversion and inferior retraction. to this problem (Strombeck, 1964; Gupta, 1965; McKissock, 1972; Weiner et al., 1973). Tension can be relieved by dividing either one pedicle (partially or completely) or the inferior portion of both pedicles. While this may relieve tension on the transposed nipple, it may also diminish viability. In an attempt to solve this problem, we have tried the vertical bipedicle flap recommended by McKissock. Unfortunately, of 8 nipples transposed in this way, 4 In addition, the de-epithelialisation of the were totally anaesthetic post-operatively. long, inferior pedicle is much too time consuming, and there is some suspicion in our minds that this long inferior pedicle may be a parasite rather than a contributor of blood supply at the new nipple site.

METHOD The nipple is transposed on a superomedial de-epithelialised pedicle (Fig. I) which contains a thin layer of subcutaneous tissue to protect the dermal blood supply. The pedicle is based on the full extent of the medial skin flap (patterned after Wise, This lateral 1956) and the entire new nipple site except for a small lateral portion. portion of the new nipple site (A in Fig. I) must be excised to obtain easy mobility in transposing the nipple. Figures 2 to 4 show the nipple and pedicle being dissected from the underlying breast tissue and rotated into place. When necessary, the mammary ducts are divided. On occasion, the lower aspect of the pedicle must be divided from the medial skin flap for a distance of I to 2 cm to facilitate rotation to the new nipple site. DISCUSSION This method of nipple transposition has been used in 24 breasts in 12 patients over the past year. Representative cases are shown in Figures 5 and 6. There have been All patients, with one exception, have retained no problems with nipple viability. sensation to pin prick and fine touch. We attribute this to the medial aspect of the dermal THE SUPEROMEDIAL DERMAL PEDICLE FOR NIPPLE TRANSPOSITION 45 pedicle which carries fibres from the anterior cutaneous branches of the 4th and 5th intercostal nerves. Weiner et al. describe a single superior dermal pedicle for nipple transposition with excellent results regarding viability but no mention of sensation. We feel the superomedial dermal pedicle is superior to the single superior dermal pedicle, because nipple sensation is retained, and in long pedicles a broader base ensures better viability. Jn reduction mammaplasty a lower wedge resection is carried out following transposition. We do not excise a core of tissue from the new nipple site, having found that this cavity alone has caused nipple retraction due to a lack of bulk support deep to the nipple. We have found this pedicle equally applicable to dermal mastopexy operations with similar results. SUMMARY A new method for nipple transposition employing a superomedial dermal pedicle is described for use in reduction mammaplasty and dermal mastopexy. The advantages include superior mobility, viability, sensation and normal appearing nipples and areolae. REFERENCES S. C. (1965).
