Swelling over the right submandibular region needs further evaluation by an ENT to see if it is a gland enlargement or just the lymph node. As regards styloid process, we need to look at the xray to comment.

Level 1B reactive lymphadenitis points more to an oral or salivary or dental infection. As for the elongated styloid process, most of the times you need to do nothing, unless you get pain while swallowing, which means that the glossopharyngeal nerve in the same parapharyngeal space is getting compressed as it is trapped between the medially curved elongated styloid process and your throat musculature which naturally bulge outwards during the process of swallowing a bolus of food. This rare condition is called Eagle's Syndrome. In my 20+ years of practice, I have only encountered 4 cases of Eagle's Syndrome, and happily, all had a great outcome after surgery.
