Submaxillary refers to the area beneath the jawbone, but it isn't a term that comes up in everyday conversation. If you're looking for some synonyms that might be more applicable, you could consider using "submental," which describes the region under the chin, or "submandibular," which is used to describe the salivary glands located in the same area. Other phrases you might find useful include "infrahyoid," which refers to the area below the hyoid bone in the neck, or "cervical," which describes the region around the neck. Whether you're writing an academic paper or just trying to describe a sore throat, having a few different phrases in your vocabulary can help you express yourself more clearly.
