ABSTRACT
Objective:To classify the types of radiographic feature of central salivary gland type malignant tumors of the jaws(CSMTJ) with studying the clinical data,radiographic characteristics and pathological classifications,and to help the diagnose CSMTJ correctly and effectively in future. Methods:The clinical,radiological and pathological features of 62 cases of CSMTJ were studied and summarized. Among these cases,52 cases were collected from the medical records of patients of the internal databank according to the World Health Organization (WHO) Histological Classification of Salivary Gland Tumors standard and 10 cases of CSMTJ were from Guangdong Provincial Stomatological Hospital. Results:The maxilla to mandible ratio was 1∶1.7,Among CSMTJ cases,central mucoepidermoid carcinoma of the jaws (CMCJ) was the most common pathological type and the second was central adenoid cystic carcinoma of the jaws(CACCJ). 62 cases of CSMTJ could be classified into four types:Unicystic type,Multicystic type,"Flame shape" type and Osteolytic type. Conclusion:The radiographic presentation of CSMTJ was very complicated and its classification was connected with tumor malignant degree. The classification was very helpful to determine the treatment methods and the prognosis of the CSMTJ.
