Clinical comparison and analysis between Warthin′s tumor and pleomorphic adenoma of the parotid gland / 重庆医学

ABSTRACT

Objective To compare and analysis clinical characteristics ,Dppler ultrasonography and CT imaging features of War‐thin′s tumor and pleomorphic adenoma of the parotid gland .Methods Thirty‐eight cases of Warthin′s tumor and 107 cases of pleo‐morphic adenoma of the parotid gland in our hospital were selected and divided into Warthin′s tumor group and pleomorphic adeno‐ma group .Average age ,gender ,position of onset ,mean course of disease ,smoking rates and Doppler ultrasonography and CT ima‐ging features of 2 groups were compared and analyzed .Results Compared with pleomorphic adenoma group ,the average age ,per‐centage of males ,smoking rates were higher in Warthin′s tumor group but the mean course of disease was short ,which showed sig‐nificant difference(P<0 .05) .The site of Warthin′s tumor mostly occurred in lower posterior polar of the parotid gland .Doppler re‐sults indicated more abundant blood supply in Warthin′s tumors group .CT imagine results also indicated higher density in Warthin′s tumors group than in pleomorphic adenomas group .Conclusion According to the group constituent ratio of disease ,average age , gender ,mean course of disease combined with Doppler ultrasonography and CT imaging features ,the tumor could be diagnosed be‐fore surgery ,which could be helpful to make the correct surgical plan .
