To describe the technique we use to obtain a fat graft from the periumbilical area to replace volume in our patients requiring total or partial orbital volume restoration or replacement.
Under local anaesthesia a one-piece fat auto-graft is obtained from one of the quadrants of the periumbilical zone through a 10- to 15-mm incision at the umbilicus edge.
Excised adipose tissue contains connective tracts, with medium and small vascular vessels with discrete thickened wall and preserved endothelium, with more blood cells, and less dead cells.
Fat grafts are the ideal fillers for patients requiring orbital volume replacement. The periumbilical fat graft technique we describe is simple, safe and fast, the learning slope shallow and the results gratifying in both the replaced volume, and the donor area with an invisible scar. The amount of fat that can be obtained with this technique through a minimal incision can be large enough.
描述我们用于从脐周区域获取脂肪移植物，以替代需要全部或部分眼眶容积恢复或替代的患者眼眶容积的技术。
在局部麻醉下，通过脐缘10至15毫米的切口，从脐周区域的一个象限获取整块自体脂肪移植物。
切除的脂肪组织包含结缔组织束，伴有中小血管，血管壁离散增厚且内皮保存完好，血细胞较多，死细胞较少。
脂肪移植物是需要眼眶容积替代的患者的理想填充物。我们所描述的脐周脂肪移植技术简单、安全且快速，学习曲线平缓，在替代容积以及供区留下不可见瘢痕方面效果均令人满意。通过最小切口用该技术获取的脂肪量足够大。
