A new study published in the Aesthetic Surgery Journal proposed a minimally invasive and reliable method that preserves breastfeeding and corrects Grade I and II inverted nipples. In this randomized controlled trial, 230 female patients with unilateral or bilateral inverted nipples and 30 patients with normal nipples who visited the Preconception Counseling Department of a hospital, from February 2009 to January 2016, were recruited. These patients were segregated into a distractor group and a control group. The women in the distractor group underwent an operation with a distractor, while those in the control group were given daily exercises. The interventions lasted 6 months. The primary endpoint was full-term pregnancy breastfeeding for 4 months, while the secondary endpoint was the completion of lactation without obvious complications such as mastitis and nipple craze. It was noted that Grade I and II nipples achieved increased height after the distractor was worn for 6 months and at 37 weeks of pregnancy. On the contrary, the control nipples achieved only a marginal improvement at 37 weeks of pregnancy. In the distractor group, the success rates were 84.9% and 79.3% for Grade I and II nipples, respectively, compared to 52.5% and 38.9%, respectively, in the control group. Additionally, after 6 months of treatment, nipples in the distractor group showed no complications, like skin numbness and nipple necrosis. Hence, it was inferred that the use of a distractor is a reliable and minimally invasive method for correcting Grade I and II inverted nipples while preserving breastfeeding.
