Retro-orbital fat volume reduction has been reported in patients with enophthalmos but could be restored by a suitable fat autograft. Buccal and subcutaneous adipose tissues were identified as possible donor sites. Samples of these and of orbital fat were obtained from fresh cadavers, and the relative volumes of collagen and of endothelial cells and the numerical density of mast cells were compared since these might influence graft survival. The results demonstrated strong similarities between orbital and buccal fat which were significantly different from subcutaneous fat. It was concluded that the buccal fat pad would be a more suitable donor site than subcutaneous adipose tissue to replace orbital fat loss and that its use merits further investigation.
据报道，眼球内陷患者存在眶后脂肪体积减少的情况，但可通过合适的自体脂肪移植恢复。颊部和皮下脂肪组织被确定为可能的供区。从新鲜尸体获取这些部位以及眶脂肪的样本，比较胶原蛋白、内皮细胞的相对体积和肥大细胞的数量密度，因为这些可能会影响移植脂肪的存活。结果表明，眶脂肪和颊脂肪之间有很强的相似性，与皮下脂肪有显著差异。得出的结论是，颊脂垫作为替代眶脂肪缺失的供区比皮下脂肪组织更合适，其应用值得进一步研究。
