abstract = {ObjectiveTo investigate the clinical characteristics, differential diagnosis and treatment of cheek mass caused by hyaluronic acid injection.MethodsFrom March 2014 to December 2018, data from 5 patients with cheek masses caused by cosmetic fillings admitted to the First Hospital of Shanxi Medical University were collected, and their clinical, imaging, surgical and pathological features were summarized.ResultsAll 5 patients were young females with a history of facial hyaluronic acid filling injection. Their clinical features were buccal and facial nodular masses, all of which were treated with surgery. The pathological report was fibrous adipose tissue with fat necrosis, and chronic inflammatory cell infiltration was observed in the interstitium. After the operation, the face shape was basically symmetrical, and there were no symptoms such as infection, limited mouth opening or facial paralysis.ConclusionThe injection of facial hyaluronic acid may cause complications of nodular masses in the cheek, and intraoral resection is an effective treatment with good prognosis.}
