The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature （primary or recurrent） and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients＇ data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula （primary or recurrent） and duration of illness. Sections from the paraffinembeded blocks were HE-stained. CK expression was immunohis-tochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups （P〈0.005）. The incidence of venous thrombosis of ranulas with diameter larger or less than 3 cm was 72.22% and 46.28% （P〈0.005）. The incidence of venous thrombosis of oral ranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula （P〈0.01）. The incidence of venous thrombosis in ranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% （P〈0.01）. The incidence of venous thrombosis with recurrent and primary ranulas was 51.85% and 64.85%, without a significant difference noted between them （P〉0.05）. It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature （primary or recurrent） of ranulas.
