The anatomic understanding of the superficial compartments of the head and neck are evolving. Recently, studies have shown that the superficial fat is sequestered into separate "compartments"; however, the superficial anatomy of the submental region of the neck has yet to be defined, and improved understanding of this area may lead to advances in our ability to rejuvenate the neck. This cadaveric investigation revealed that there is one superficial fat compartment in the submental region. The anterior boundary of this compartment, previously without name, has been labeled the "submental septum." The posterior boundary of the submental fat compartment is created by a septum that arises from the platysma at a point superficial to the hyoid. Because this area is over the hyoid, it has been named the "suprahyoid septum." The lateral septal boundaries have been labeled the "digastric septae."
对头颈部浅层间隙的解剖学理解正在不断发展。最近的研究表明，浅层脂肪被分隔成单独的“间隙”；然而，颈部颏下区域的浅层解剖结构尚未确定，对该区域的更好理解可能会提高我们使颈部年轻化的能力。这项尸体解剖研究显示，颏下区域只有一个浅层脂肪间隙。该间隙的前边界，以前没有名称，被标记为“颏下隔”。颏下脂肪间隙的后边界由一个从颈阔肌浅层发出的隔形成，位于舌骨上方。由于这个区域位于舌骨上方，因此被命名为“舌骨上隔”。侧部的分隔边界被标记为“二腹肌隔”。
