Abstract

Background:

The role of leukotriene inhibitors used immediately postoperatively to potentially influence the development of capsular contracture is unknown. The purpose of this study was to evaluate the incidence of capsular contracture among women undergoing primary smooth silicone gel breast augmentation, with or without postoperative leukotriene inhibitor therapy.

Methods:

Between 2007 and 2013, 1122 consecutive women undergoing primary silicone gel breast augmentation were evaluated retrospectively. All underwent augmentation with smooth, Mentor Memory Gel implants, using a dual-plane technique, with periareolar or inframammary approaches. Patients were treated voluntarily with either no leukotriene inhibitor, montelukast (Singulair), or zafirlukast (Accolate) for 3 months. All patients received informed consent for the off-label use of leukotriene inhibitors. Liver function studies were obtained for all patients undergoing Accolate therapy after 1 month of therapy. The presence of capsular contracture was measured by the Baker scale at 1 year postoperatively.

Results:

Patients receiving Accolate therapy (n = 520) demonstrated an encapsulation rate of 2.19 percent. Women receiving Singulair therapy (n = 247) had an encapsulation rate of 3.27 percent. Patients not receiving leukotriene inhibitor therapy had an encapsulation rate of 5.02 percent. There were no long-term complications among patients evaluated.

Conclusions:

Accolate therapy used for 3 months postoperatively was associated with significantly lower capsular contracture rates compared with untreated patients at 1-year follow-up (p < 0.05). Patients treated with Singulair demonstrated lower contracture rates compared with controls, but the differences were not statistically significant. The findings suggest that Accolate therapy, with monitoring and consent, reduces the incidence of capsular contracture following primary smooth silicone gel breast augmentation.

CLINICAL QUESTION/LEVEL OF EVIDENCE:

Therapeutic, III.
