Autologous fat grafting to the breast for cosmetic enhancement remains controversial because the efficacy and fate of fat grafting to the breast are primarily unknown. In this report, we present our retrospective study in 66 patients who underwent autologous fat grafting to the breast for various cosmetic reasons and who were followed with sonography, mammography, or magnetic resonance imaging (MRI).
Sixty-six patients who desired cosmetic enhancement of the breast for various reasons underwent autologous fat transplantation between August 2000 and March 2005 in our institution. The cosmetic outcome was assessed by the plastic surgeons as well as the patients. The imaging features of fat necrosis, cyst formation, and calcification in these patients were carefully studied and biopsies of palpable lumps were evaluated histologically.
All patients were followed from 13 to 61 months with an average of 37 months. Breast cosmetic contour was significantly improved in 28 patients (42.4%), improved in 24 patients (36.4%), and not improved in 14 patients (21.2%) as judged by the plastic surgeons. Twenty-seven patients (40.9%) were very satisfied, 26 patients (39.4%) were satisfied, and 13 patients (19.7%) were unsatisfied. Eleven patients (16.7%) developed liponecrotic cysts but only two patients elected to have the breast lump surgically removed.
Autologous fat grafting to the breast can be a useful procedure for cosmetic enhancement in many patients who desire such a procedure. Patients with breast contour deformities after removal of silicon implants were found to be the best candidates for fat grafting. The primary long-term complication is the formation of liponecrotic cysts which have characteristically benign appearances in sonography, mammography or MRI.
自体脂肪移植到乳房进行美容丰胸仍存在争议，因为乳房脂肪移植的疗效和转归基本未知。在本报告中，我们展示了对66例因各种美容原因接受自体脂肪移植到乳房且接受超声、乳腺X线摄影或磁共振成像（MRI）随访的患者的回顾性研究。
2000年8月至2005年3月期间，66例因各种原因希望进行乳房美容丰胸的患者在我们机构接受了自体脂肪移植。美容效果由整形外科医生和患者进行评估。仔细研究了这些患者脂肪坏死、囊肿形成和钙化的影像学特征，并对可触及肿块进行活检并进行组织学评估。
所有患者随访13至61个月，平均37个月。整形外科医生判断，28例患者（42.4%）乳房美容轮廓显著改善，24例患者（36.4%）有所改善，14例患者（21.2%）未改善。27例患者（40.9%）非常满意，26例患者（39.4%）满意，13例患者（19.7%）不满意。11例患者（16.7%）出现脂肪坏死性囊肿，但只有2例患者选择手术切除乳房肿块。
自体脂肪移植到乳房对许多希望进行该手术的患者来说可能是一种有用的美容方法。发现硅植入物取出后乳房轮廓畸形的患者是脂肪移植的最佳候选人。主要的长期并发症是脂肪坏死性囊肿的形成，其在超声、乳腺X线摄影或MRI中具有典型的良性表现。
