The left parotid gland duct is dilated due to excessive secretion from parotid gland or duct injury.  

Case Discussion

Salivary gland injury is uncommon and expresses a wide variety of injury starting from the laceration of duct or gland, sialadenitis, and facial nerve or vascular injury. The swelling was reduced after one month without follow up imaging.
