Blunt trauma to the parotid resulting in the formation of a sialocele is rare, with only three cases identified in the literature. We present a unique case involving a 32-year-old man with blunt trauma resulting in a left mandibular angle fracture. The patient underwent open reduction and internal fixation of the left mandibular angle fracture via transoral approach. At follow-up, after resolution of the edema from the injury, a sialocele was noted in the region of the left anterior parotid gland. The patient was treated conservatively with antisialagogues, pressure dressings, and multiple percutaneous aspirations that ultimately resulted in resolution of the sialocele.
