Does the Use of Intraoperative Breast Sizers Increase Complication Rates in Primary Breast Augmentation? A Retrospective Analysis of 416 Consecutive Cases in a Single Institution.

Background. Is the use of intraoperative breast sizers beneficial for plastic surgeons or do they result in higher complication rates? Methods. This is a retrospective study of 416 consecutive cases of primary breast augmentation with silicone implants at the Plastic Surgery Service of Professor Ivo Pitanguy at the 38th Infirmary Santa Casa Misericórdia Hospital, Rio De Janeiro, from January 2011 to March 2014. 212 cases (51%) were carried out with use of intraoperative breast sizers with 204 cases (49%) without the use of implant sizers. This study compares the outcome of cases that employed the use of intraoperative implant sizers versus those that did not in terms of infection, hematoma/seroma formation, and capsular contracture. Results. Of 416 primary breast augmentation cases, there were 5 cases of infection (1.2%), 4 cases of seroma (1%), 3 cases of hematoma (0.7%), and 7 cases of capsular contracture (Baker's Grade III/IV)(1.7%). Total complication rate limited to infection, seroma, hematoma, and capsular contracture was 1.15% (95% CI 0.96-1.93%). There was a significant difference in the scores for breast sizers (M = 4.3, SD = 1.4) and no breast sizers (M = 2.3, SD = 0.87) conditions, t(8) = 2.79, p = 0.018. The use of implant sizers was correlated with a higher complication rate. Conclusion. Good results could be obtained without the use of breast sizers in primary breast augmentation with use of a biodimensional tissue based planning system while eliminating risks of infection and reducing intraoperative time. Notwithstanding, in a residency program breast sizers can be an excellent training tool to shorten the learning curve in the novice surgeon.
