BACKGROUND: Anatomical implants provide a wide range of options in terms of implant dimensions for breast augmentation. Nevertheless, many surgeons choose not to use anatomical implants due to the risk of rotation malposition and because their advantages over round implants are not clearly defined.
METHODS: A retrospective review of medical records was performed on all women who underwent breast augmentation or implant exchange with microtextured anatomical implants from 2012 to 2019 in a single private clinic. The authors focused on the outcomes of a subgroup of women with glandular ptosis and nipple placement below the inframammary fold who underwent breast augmentation with anatomical implants. Furthermore, the incidence and risk factors for implant rotation were analyzed.
RESULTS: In total, 653 women underwent primary breast augmentation (n = 529) or implant exchange (n = 124) with anatomical implants. The median follow-up period was 2.7 years (interquartile range, 1.6 to 3.9 years). The incidence of implant rotation was 14 (2.6 percent) in the primary augmentation group and four (3.2 percent) in the implant exchange group. Implant rotation was not associated with type of surgery (p = 0.76), implant projection (p = 0.23), or implant height (p = 0.48). The authors successfully used anatomical implants to elevate the nipple in 92.9 percent of the women with glandular ptosis without using a mastopexy.
CONCLUSIONS: The study results indicate that the rotation risk with microtextured implants is similar to that with macrotextured implants. Furthermore, the authors found that high-projection anatomical implants can be used as an alternative to augmentation-mastopexy in women with glandular ptosis.
