Incision and Capsular Contracture Risk: Is There a Relationship in Breast Augmentation and Augmentation/Mastopexy?

Breast implants can be introduced through a variety of incisions, most commonly an inframammary incision, but also a periareolar incision or an axillary incision. Usually, the implant is inserted through the same incision used in performing an augmentation/mastopexy. Some authors use a separate inframammary incision. Capsular contracture is the most common complication of breast augmentation. One theory holds that it is caused by an infected biofilm, prompting surgeons to minimize implant handling, known as the "no touch" technique. This review was undertaken to investigate the relationship, if any, between the access incision and the risk of capsular contracture.

An electronic literature search was conducted to identify publications comparing capsular contracture rates by the access incision.

Ten studies were evaluated. Most were retrospective series. Three were prospective core studies. Some studies reported an increased risk of capsular contracture for a periareolar incision; a similar number did not. One study supported a separate inframammary incision at the time of vertical augmentation/mastopexy.

Bacterial studies in the last decade show that the resident bacteria on the skin surface and within breast tissue are similar. Sophisticated microbiological evaluation of breast capsules reveals that the microbiome relates to the patient, as opposed to a specific bacterial profile for capsular contracture. A review of the statistics used in determining an advantage for a separate incision at the time of vertical augmentation/mastopexy reveals that there is no statistically significant risk reduction when using an additional inframammary incision, which adds an unnecessary scar.

The access incision at the time of breast augmentation or augmentation/mastopexy is unlikely to affect the capsular contracture risk. There is no need to make a separate incision to insert the implant at the time of augmentation/mastopexy, or to isolate the implant from contact with breast parenchyma. Little evidence supports the "no touch" technique. The etiology of capsular contracture remains unknown.
