RESUMEN
Background: Autologous reconstruction techniques can provide a long-lasting natural breast reconstruction for patients. This study aimed to further investigate outcomes in the conversion of breast implant reconstruction into a lipofilled mini dorsi flap, focusing on reviewing its techniques, efficiency, and final results. Methods: Over 3 years, we performed a number of breast implant replacements via the lipofilled mini dorsi flap technique. The artificial implants were replaced to a deepithelized flap. The efficiency and tolerance of the technique were evaluated by the whole surgical team, and the achieved results were also analyzed by the patients in terms of postoperative pain, functional impact, and the softness of the reconstructed breast by comparing their prior condition to the lipofilled mini dorsi flap condition at least 9 months after operation. Results: Forty-seven consecutive operations were prospectively studied. The mean ± standard deviation volume of the removed implants was 348.66 ± 86.54 mL. The mean volume of fat injected was 284.13 ± 62.94 mL. The procedure's average duration was 108.93 ± 17.65 minutes. The surgical team evaluated the results as very satisfactory in 32 cases (68.1%), satisfactory in 15 cases (31.9%), and moderately satisfactory or unsatisfactory in zero cases (0.0%). Eighteen patients (38.3%) evaluated their reconstruction as very good, while 20 patients (42.6%) considered their reconstruction as good, four (8.5%) as average, and zero (0.0%) as insufficient. Conclusion: According to our experience, the lipofilled mini dorsi flap is a simple, less invasive, and quick procedure to convert breast implants into natural breast reconstruction.
RESUMEN
INTRODUCTION: The traditional extended latissimus dorsi flap technique, in addition to lipofilling, has been one of the main procedures used for breast reconstruction after mastectomy. However, to obtain excellent results, this technique requires a large muscle harvest and further lipofilling sessions. The lipofilled mini dorsi flap technique, performed in a single operation, appealed to us as a way to improve the traditional technique.We present our experience with the lipofilled mini dorsi flap technique in a new scenario. MATERIALS AND METHODS: We performed breast reconstruction with a lipofilled mini dorsi flap in female patients with breast cancer who underwent mastectomy and immediate breast reconstruction with a lipofilled mini dorsi flap. The operative technique is detailed in this article. The results were evaluated by the patients and the surgical team. RESULTS: We performed 72 lipofilled mini dorsi flap procedures during breast reconstruction surgery from May 2017 to January 2019. Fifty-nine (81.9%) cases were immediate reconstructions. Complications, such as infection or necrosis of the flap, were not observed in this study. We noticed seroma and 1 case of infected lymphocele, which was drained.Body mass index (BMI) was directly related to postoperative dorsal seroma. The authors reported that greater BMI was associated with a higher seroma volume.Most patients evaluated their reconstruction as satisfactory. The surgical team evaluated most of the results as very satisfactory or satisfactory. There were no cases of unsatisfactory results reported either by the patients or the surgical team. CONCLUSIONS: The lipofilled mini dorsi flap technique is an efficient, elegant, and less invasive solution that is more easily and quickly performed and achieves excellent long-term results in the immediate breast reconstruction scenario. For the first time to our knowledge, lipofilling was used to reduce the extent of latissimus dorsi dissection. The postoperative follow-up was better tolerated by patients. This technique may be offered to patients regardless of oncological treatment. In our experience, the lipofilled mini dorsi flap method has become the primary technique for immediate breast reconstruction.
