Requests for buttock augmentation are increasing in the United States because of changes in lifestyle and fashion that emphasize the "gluteal aesthetic unit."
We review the use of micro fat grafting for enhancing the buttocks in a series of 566 patients.
Tumescent solution (1 mg epinephrine per 1000 mL saline solution) was infiltrated; for small cases the volume used was less than half the amount of expected fat to be harvested. Harvesting was accomplished either manually with a syringe or with a liposuction pump that allowed precise control of the vacuum. The fat was injected both intramuscularly and subcutaneously into all levels of the desired area for augmentation of the buttocks. The typical augmentation averaged 300 to 400 mL per side but ranged from 175 mL to about 800 mL, depending on the patient's desires and the amount of donor fat available.
Patient and physician satisfaction with the results was high. Approximately 50% to 75% of the fat grafted remains in the long term. Complications included cellulitis (1.9% of cases), which responded promptly to treatment with cephalosporin, and infrequent seromas and hematomas (0.8% of cases).
Buttock augmentation by micro fat grafting is a safe, simple procedure. Compared with implant placement, the advantages of micro fat grafting include greater flexibility in the size and placement of augmentations, less pain and faster recovery for the patient, and less risk of complications. The technique is limited only by the amount of donor fat available. (Aesthetic Surg J 2001;21:311-319.).
由于生活方式和时尚的变化强调“臀美学单位”，美国对丰臀的需求正在增加。
我们回顾了在一系列566例患者中使用微脂肪移植来丰臀的情况。
浸润肿胀液（每1000毫升盐溶液含1毫克肾上腺素）；对于小面积手术，使用的量少于预期采集脂肪量的一半。采集脂肪可通过手动用注射器或使用能精确控制真空度的抽脂泵来完成。将脂肪肌肉内和皮下注射到所需丰臀区域的各个层次。典型的丰臀量平均每侧为300至400毫升，但根据患者的需求和可用供体脂肪量，范围从175毫升到约800毫升不等。
患者和医生对结果的满意度很高。长期来看，移植的脂肪约有50%至75%留存。并发症包括蜂窝织炎（1.9%的病例），用头孢菌素治疗后迅速好转，以及罕见的血清肿和血肿（0.8%的病例）。
微脂肪移植丰臀是一种安全、简单的手术。与植入假体相比，微脂肪移植的优点包括丰臀大小和位置的灵活性更高、患者疼痛减轻且恢复更快，以及并发症风险更低。该技术仅受可用供体脂肪量的限制。（《美容外科杂志》2001年；21:311 - 319。）
