A full or poorly defined jawline can result from several different anatomical features. In some patients, prominent submandibular glands contribute to fullness beneath the jaw that cannot be corrected with liposuction or skin tightening alone.
What Is Submandibular Gland Reduction?
The submandibular glands are a pair of salivary glands located beneath the jawline, one on each side of the upper neck. In some patients, the glands are enlarged, naturally prominent, or have descended below the jawline, creating visible fullness on either side of the neck.
Prominent glands may resemble submental fat, but they are different tissues that require different treatments. The glands are located beneath the platysma within the deeper layers of the neck. Liposuction treats fat—not glandular tissue—and therefore cannot correct fullness caused by a prominent gland.
The submandibular glands are only one possible contributor to an undefined jawline. Loose skin, superficial and deep fat, platysma banding, prominent digastric muscles, and skeletal anatomy may also affect the neck contour. For this reason, gland reduction is generally considered as one component of comprehensive deep neck contouring rather than an isolated procedure.
