分离的颧骨脂肪垫在解剖学上的存在还没有被广泛认识。Hamra在他关于“深层除皱术”的论文中描述了前中面部皮下脂肪厚度的增加。尸体和临床研究证实了一个局部的皮下脂肪垫覆盖在颧骨体和上颌骨的一致存在。眶下皮肤和颧脂肪垫向下移位导致鼻唇沟突出。颧脂肪垫的手术解剖始于眼轮匝肌平面上的颧隆起，浅至由SMAS包绕的颧弓肌和提上睑肌起点。有一个容易剥离的平面深入脂肪垫，延伸到鼻唇沟。突出鼻唇沟的手术矫正是通过破坏颧骨脂肪垫并通过皮瓣牵引将其侧向推进，并通过在脂肪垫的外侧边缘和外侧颧骨隆起处的皮下筋膜之间的缝合进行额外的向上固定来加强的。
The anatomic presence of a discrete malar fat pad has not been widely recognized. In his paper on the ''deep plane rhytidectomy,'' Hamra describes the increased thickness of the subcutaneous fat over the anterior mid-face. Cadaver and clinical studies confirm the consistent presence of a localized subcutaneous malar fat pad overlying the body of the zygoma and maxilla. Downward displacement of the infraorbital skin and underlying malar fat pad causes an increased prominence of the nasolabial fold. The surgical dissection of the malar fat pad starts from the malar eminence at the plane of the orbicularis oculi muscle and superficial to the origin of the zygomaticus and levator muscles, which are invested by the SMAS. There is an easily dissected plane deep to the fat pad that extends to the nasolabial crease. Surgical correction of the prominent nasolabial fold is enhanced by undermining the malar fat pad and advancing it laterally by traction on the skin flap with additional upward fixation by sutures between the lateral edge of the fat pad and the subcutaneous fascia at the lateral malar eminence.
