PURPOSE: To evaluate the incidence and condition of platysma infiltration in benign tumors, malignant tumors, and inflammatory disease in the parotid gland using CT or MRI.
MATERIALS AND METHODS: Patients with benign tumors (n = 314), malignant tumors (n = 52), and inflammatory disease (n = 22) in the parotid gland were included. The incidence of platysma infiltration and the relationship between platysma infiltration and the location, capsular involvement, and focality of the mass were retrospectively evaluated using CT or MRI.
RESULTS: The incidence of platysma infiltration was 0% in benign tumors,19.2% in malignant tumors (10/52), and 50.0% in inflammation (11/22). Platysma infiltration was positive in 10 of 13 patients with inflammatory lesion with capsular involvement. Platysmal infiltrations in inflammatory lesion showed diffuse lesion in 10 patients and focal lesion in one patient. Malignant tumor with platysmal infiltration showed all capsular involvement, and diffuse lesion in seven and focal lesion in three.
CONCLUSION: Platysma infiltration was more common in patients with inflammatory disease than those with malignant tumors or benign tumors. In inflammatory disease, platysma infiltration was more common in patients with capsular involvement or diffuse lesion.
