Resumen

Background and objective. Breast augmentation is one of the most performed aesthetic surgeries worldwide. Choosing the appropriate plane for implant placement is crucial to optimize results and reduce complications. Multiple placement planes have been described, each with advantages and disadvantages. The Tri-B-Plane technique is presented as an evolution of the dual plane, integrating 3 key concepts: improved coverage of the inferior pole, strategic division of the pectoralis muscle, and a third plane of coverage, all with the aim of optimizing implant stability, coverage, and projection. Methods. Surgical technique is described and a retrospective, descriptive, cross-sectional study was performed on 67 patients who underwent breast implant augmentation with the Tri-B-Plane technique between January 2020 and June 2024 in a private clinic in Lima, Peru. Patients with implant replacement or mastopexy with augmentation were excluded. Clinical characteristics, surgical techniques, implant type, and postoperative complications were documented. Results. The patients had a mean age of 28 years; 76.1% had breast hypoplasia without ptosis, while 23.9% had tuberous breasts. Round, predominantly smooth, high-profile implants were used, with an average volume of 295 cc. Periareolar access was performed in all cases, and 77.6% of surgeries were performed under local anesthesia and sedation. Complications were minimal, with 2.9% asymmetry of the submammary sulcus and 1.5% partial dehiscence. Conclusions. The Tri-B-Plane technique offered in our group of patients who underwent breast augmentation with implants, optimal implant coverage by means of a multiplanar structure which contributes to improve stability, breast projection and reduce complications such as dynamic breast. Its application is wide, especially in patients with tuberous breast, athletes or with specific needs of coverage and support.
