Abstract

The results of submental lipectomy often remain suboptimal, and in some cases this may be due to the presence of residual fat deep to the platysma muscle. This study was undertaken to determine the relative amounts of fat superficial and deep to the platysma muscle. A dissection of the submental region of 20 cadavers revealed a mean weight of fat lying superficial to the platysma muscle of 8.4 grams. The mean weight of fat lying deep to the platysma muscle but superficial to the mylohyoid muscle was 3.7 grams. In three cases (15%), the weight of fat deep to the platysma muscle was greater than 50% of the total fat. This is of significance with respect to those submental lipectomy procedures that normally address only the fat superficial to the platysma.

摘要

颏下脂肪切除术的效果往往不尽人意，在某些情况下，这可能是由于颈阔肌深层存在残余脂肪。本研究旨在确定颈阔肌浅面和深面脂肪的相对含量。对20具尸体的颏下区域进行解剖后发现，颈阔肌浅面脂肪的平均重量为8.4克。颈阔肌深面但下颌舌骨肌浅面脂肪的平均重量为3.7克。在3例（15%）中，颈阔肌深面脂肪的重量超过了总脂肪的50%。这对于那些通常只处理颈阔肌浅面脂肪的颏下脂肪切除手术具有重要意义。
