Abstract：Objective To evaluate the value of high frequency ultrasound in the diagnosis of jaw tumors and tumor-like le-sions.Methods The ultrasonic results of 43 patients with jaw lesions confirmed by surgical pathology were collected.The ultra-sonic characteristics of different pathological types were summarized.Results All 43 patients in this study included 22 cases of jaw cysts,i.e.,11 cases of odontogenic keratogenic cysts and 11 cases of odontogenic jaw cysts.There were16 cases of benign tu-mors and tumor-like lesions,of which 7 cases were ameloblastomas.The others included odontogenic myxoma(n=1),ossifying fibroma(n=2),vascular malformation of jaw(n=2),fibrous dysplasia of bone(n=3)and Langerhans cell hyperplasia(n=1).5 cases of jaw malignant tumors included plasmacytoid myeloma(n=1),mucoepidermoid carcinoma(n=1),osteosarcoma(n=1),squamous-cell carcinoma(n=1),and inflammatory myofibroblastoma(n=1).The sensitivity and specificity of ultra-sound in the diagnosis of malignant lesions were 80.00%and 97.37%,respectively.The accuracy was 95.35%.The ultrasono-graphic features of jaw cyst were as follows:no echo area in the lesion,good or bad sound transmission,no obvious blood flow signal in the lesion by color Doppler,and with the coincidence rate of 90.91%.There were low or no echo in the benign lesions,the blood flow of the solid part of the lesion was different from Grade I to III detected by color Doppler,the coincidence rate was 81.25%,the cortex of the malignant lesion was discontinuous and wormlike,the surrounding soft tissue mass with irregular shape had abundant blood flow,and the coincidence rate was 80.00%.Conclusions Ultrasound can identify the cystic and solid nature of jaw tumors and tumor-like lesions,differentiate the benign and malignant lesions,and provide a new method for the diagnosis of jaw lesions and a reliable basis for the selection of clinical treatment.
