Correction of inverted nipples with the double-track sun-cross running suture technique

Various techniques have been reported for correcting inverted nipples; however, problems such as incomplete correction, recurrence, scarring and nerve or duct injury persist. To minimise the recurrence rate and reliably attain a well-projected nipple, we developed a technique involving a single suture that runs through both the periphery and the core of the nipple. After the dissection and release of fibrotic connective tissue, an absorbable monofilament suture was passed through the periphery and core to leave double tracks of the suture at all locations, creating the final shape of a cross inside a circle (resembling the sun-cross symbol). Finally, the suture was tied in a purse-string manner to push the nipple outward. We performed this surgery on 34 congenital cases, comprising 29 patients with bilateral inverted nipples, 5 patients with a unilateral inverted nipple and 12 patients with an acquired deformity. During a mean follow-up period of 22.4?months, all of the corrected nipples remained everted without reinvagination. We successfully corrected inverted nipples with the double-track sun-cross running suture technique, which provided long-lasting eversion and created an aesthetically pleasing nipple contour.
