I think I would start off by asking you to make sure that it is in fact your submandibular glands (salivary glands) that are the problem. Sometimes extra fat that wasn't removed can look and even feel this way. If it is, options are limited from a cosmetic perspective. The problem with these glands is that there are crucial nerves around them. The Hypoglossal nerve, which controls the movement of your tongue, the Lingual nerve which carries taste and touch from your tongue and a nerve called the marginal mandibular nerve which allows you to move the corner of your mouth. If these are damaged there can be unfortunate complications. Here in Ottawa at my practice I remove submandibular glands for non-cosmetic reasons and it is a surgery that requires skill and knowledge. I would not recommend a cosmetic removal to my patients. Other options include using fillers to try to mask the angles and perhaps blunt the shadowing effect. Using Botox is possible, however the risk is potential temporary paralysis of facial muscles. Also, i can affect swallowing if not done perfectly in this area. Sorry for your trouble with this, but I'd recommend seeing a physician in person to really see what the best options are.
