Abstract: Objective To summarize clinical manifestations and treatment results of parotid lipoma. Methods The medical history, clinical manifestations, imaging examination, treatment and prognosis of 17 patients with parotid lipoma were retrospectively analyzed. Results All 17 cases of parotid lipoma were located in the superficial lobe and presented as a painless mass. There were 6 females and 11 males, aging from 33 to 76, with an average age of 50.7. Ultrasound examination showed a clear and hypoechoic mass within the parotid gland, and CT examination showed a clear boundary, intact capsule, and low-density mass. Partial parotidectomy with preservation of the facial nerve was performed, and there was no symptom of facial nerve paralysis and no recurrence after operation. Conclusion Parotid lipoma is more common in men, manifested as a painless and gradually enlarged mass in parotid gland. The tumor is completely removed in the normal parotid gland with partial parotidectomy, and the prognosis is good.
