Capsular Contracture Rate After Breast Augmentation with Periareolar Versus Other Two (Inframammary and Transaxillary) Incisions: A Meta-Analysis

Abstract

Background

Capsular contracture has been the most common complication of cosmetic breast augmentation. The effect of incision pattern on capsular contracture is still unclear. This meta-analysis demonstrates current evidence with regard to the comparison of capsular contracture rate between periareolar and other two (transaxillary and inframammary) incisions.

Methods

PubMed, EMBASE, and Cochrane databases were searched up to January 2017. The results of selected studies were meta-analyzed to obtain a pooled odds ratio of the effect of periareolar versus other two incision patterns (transaxillary or inframammary incision) of breast augmentation on capsular contracture rates. In addition, subgroup analyses were performed on periareolar versus transaxillary groups and periareolar versus inframammary groups with regard to capsular contracture rate.

Results

Seven comparative studies were selected and meta-analyzed. Five of the seven studies reported a higher rate of capsular contracture on patients with periareolar incisions. The results showed a significantly higher rate of capsular contracture with periareolar incisions compared with other two incisions (OR, 1.83; 95% CI, 1.06–3.15, p = 0.03). Subgroup results showed no significant difference of capsular contracture between periareolar incisions and transaxillary incisions (OR, 0.94; 95% CI, 0.52–1.64, p = 0.79) and showed a significantly higher rate of capsular contracture in periareolar incisions compared to inframammary incisions (OR, 1.91; 95% CI, 1.06–3.43, p = 0.03).

Conclusion

The results of this meta-analysis demonstrate the contributing effects of periareolar breast augmentation on the rate of capsular contracture. However, more studies with longer tracking periods and higher quality should be conducted to further verify this conclusion.
