Introduction: Achieving breast symmetry following unilateral mastectomy remains a challenge. Contralateral procedures are usually necessary to achieve breast symmetry. Controversy exists regarding whether these symmetry procedures should be performed at the time of the initial reconstruction or on a delayed basis.
Materials and methods: The study included 105 patients who had unilateral mastectomy, of which 55 had a simultaneous (immediate) contralateral symmetry procedure and 50 had a delayed contralateral symmetry procedure. Outcomes were compared and assessed for each cohort based on demographics, complications, and patient satisfaction.
Results: The delayed cohort required more procedures (3.4 vs. 1.8, p < 0.0001) but shorter overall hospitalization length (2.8 vs. 4.1 days, p < 0.0001). The two cohorts experienced a similar rate of revision (38.3% vs. 49.3%, p = 0.17) The delayed cohort required a contralateral balancing procedure after completion of reconstruction more often than the immediate cohort (p = 0.021). Overall reconstruction-specific complication rates were similar in both cohorts. The 36-Item Short-Form Health Survey (SF-36), a validated questionnaire for quality-of-life assessment, was administered 3 months after surgery and demonstrated that both cohorts reported similar outcomes when comparing their satisfaction with treatment.
Conclusions: The results of this study demonstrate that immediate contralateral symmetry operations can be performed safely without increased morbidity. A new algorithm is presented.
