Summary
Modified abdominal advancement flap (modified AAF) offers good cosmetic outcomes and high patient satisfaction in breast-conserving surgery (BCS). This technique is beneficial for older patients and those with larger breasts.
Area of Science:
- Plastic Surgery
- Oncology
- Reconstructive Surgery
Background:
- Breast-conserving surgery (BCS) aims to preserve breast aesthetics post-cancer treatment.
- Abdominal advancement flap (AAF) techniques are utilized in breast reconstruction.
- Evaluating modifications to AAF is crucial for optimizing BCS outcomes.
Purpose of the Study:
- To assess the efficacy of modified AAF, with or without the Ochikomanai method, in BCS.
- To evaluate cosmetic results and patient satisfaction following modified AAF procedures.
- To compare modified AAF with standard AAF for BCS.
Main Methods:
- Retrospective cohort study involving 88 patients (89 breasts) undergoing BCS with modified AAF.
- Inclusion of the Ochikomanai method in some cases.
- Comparison with a historical cohort using standard AAF.
Main Results:
- Low complication rate (11%) with no observed fat necrosis; all resolved conservatively.
- Excellent or good cosmetic results in 95% of cases (41 excellent, 26 good).
- High patient satisfaction (over 89%) across most categories, indicating the technique's usefulness.
Conclusions:
- Modified AAF, with or without the Ochikomanai method, is a valuable technique for BCS.
- The procedure yields acceptable cosmetic results, particularly for older patients and those with medium to large breasts.
- High patient satisfaction supports the modified AAF as a beneficial option in breast reconstruction after BCS.
