Functional return after implant -based breast reconstruction: A prospective study of objective and patient -reported outcomes

摘要

Background: There is sparse literature studying the functional morbidity of subpectoral implant- based breast reconstruction. We aimed to prospectively investigate this technique?s impact on objective upper extremity function and patient-reported outcomes. Methods: Women undergoing mastectomy and immediate subpectoral tissue expander inser- tion with ADM sling were enrolled from November 2014 to August 2016. Preoperative evaluation of shoulder range of motion, pectoralis major strength, and Quick Disabilities of the Arm, Shoul- der, and Hand (QuickDASH) and Breast-Q surveys were conducted before surgery and at 1 month and 6 months postoperatively, or until return to baseline pectoralis major strength. Results: Eighteen women (mean age, 51 years, SD 9.6, range 35-72 years) comprising 26 breast reconstructions completed postoperative follow-up. The average follow-up length was 9 months (range, 3-18 months; SD, 144 days). At 1-month follow-up, there was a statistically significant decrease in lower and non dominant upper fiber pectoralis strength from preoperative baseline (p < 0.05). At final postoperative follow-up, 24 reconstructions (92.3%) recovered to at least 80% of preoperative strength in upper and lower fibers.
