A review of different breast reconstruction methods

Breast reconstruction is necessary for the comprehensive treatment of breast cancer. For successful breast reconstruction, the timing of surgery and the surgical methods used are vital. The methods of breast reconstruction can be divided into implant-based breast reconstruction (IBBR) and autologous breast reconstruction (ABR). With the development of acellular dermal matrix (ADM), IBBR has become more common in clinical practice. However, the choice for the position in which the implant should be placed (prepectoral or subpectoral) and the use of ADM is currently controversial. We summarized the differences in indications, complications, advantages, disadvantages, and prognosis between IBBR and ABR. We also compared the indications and complications of different flaps in ABR and found that the LD (latissimus dorsi) flap is suitable for Asian women who have a low body mass index (BMI) and a low incidence of obesity, while the DIEP (deep inferior epigastric perforator) flap can be used in patients with severe breast ptosis. In conclusion, immediate breast reconstruction with an implant or expander is the primary method, as it causes lesser scarring and requires a shorter time compared to ABR. However, for patients with severe breast ptosis or reluctant to receive an implant, ABR can be performed for a satisfying cosmetic result. Indications and complications of different flaps in ABR are also inconsistent. Surgeons should make surgical plans based on the preferences and conditions of each patient. In the future, breast reconstruction methods need to be further refined, and minimally invasive and personalized approaches need to be implemented to provide more benefits to patients.
