A Comparative Study on Aesthetic and Pain Outcomes in Flap Versus Implant Breast Reconstruction After Mastectomy
Bibliographic record
Abstract
Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death among women worldwide. Surgical treatments, including mastectomy and subsequent breast reconstruction, are critical components of breast cancer management. This systematic review compares the outcomes of flap versus implant reconstruction post-mastectomy, focusing on aesthetic differences, pain, recovery, and psychological adaptation. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, we conducted a comprehensive literature search across PubMed, Cochrane, and ScienceDirect databases. Inclusion criteria targeted studies comparing aesthetic outcomes, pain, recovery costs, duration, and psychological adaptation between flap and implant breast reconstructions. We excluded non-English and non-Spanish studies, case reports, and those without full-text availability. The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). From an initial pool of 25,881 articles, 16 high-quality studies involving 14,196 participants were selected for synthesis. Flap reconstruction was associated with higher patient satisfaction regarding aesthetic outcomes and psychological well-being but also had higher complication rates, including infections and wound dehiscence. Implant reconstruction showed fewer complications but did not achieve the same level of patient satisfaction. Flap reconstruction, despite its higher complication rates, tends to provide superior aesthetic and psychological outcomes compared to implant reconstruction. These findings highlight the importance of personalized treatment plans considering individual patient needs and preferences. Future research should focus on long-term randomized controlled trials (RCTs) and standardized outcome measures to further delineate the comparative effectiveness of these reconstruction techniques. Personalized care and ongoing research are essential to improving the quality of life for breast cancer survivors undergoing reconstruction.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
