A New Method for Inverted Nipple Treatment with Diamond-Shaped Dermal Flaps and Acellular Dermal Matrix: A Preliminary Study

Abstract

Background: Patients with inverted nipples experience various uncomfortable complications including recurrent infections. Regarding the level of severity of inverted nipple, those that are higher than grade II (as classified by Han and Hong) requires surgical correction. Many methods have been proposed to treat the inverted nipple. However, even after treatment, recurrence has always posed a problem. Thus, we propose a new method using the diamond-shaped dermal flap with acellular dermal matrix to treat the inverted nipple.

Method: Between March 2019 and February 2022, a total of five patients with grade III were studied in this study. Two diamond-shaped flaps were designed at the 3 and 9 o'clock positions of the nipple. This dermal flap was elevated and wrapped around the nipple column at the nipple base. The lactiferous ducts in female were all divided. In addition, acellular dermal matrix was inserted to fill the dead space of the nipple base. The nipple height and scar evaluation were conducted on 6 month, 12 month postoperatively. Overall satisfaction and complications were also checked at the last visit.

Results: The inverted nipple was resolved and no complications such as hematoma, infection, and necrosis were reported. The projection was maintained without any recurrence, with a slight decrease of 1.5 mm (reduction in 20%) in median value. There were no major or minor complications found except for a few small scars, and the patient was satisfied with the esthetic outcomes during the follow-up.

Conclusion: This is a fast and simple technique for the surgical correction of inverted nipples. Using the acellular dermal matrix, projection and suspension were safely maintained without complications. This technique could be an option for the surgical treatment of severe types of inverted nipples.
