Abstract
OBJECTIVES: The aim of the present study was to evaluate the diagnostic efficacy of ultra-high frequency ultrasound (UHFUS) imaging of intraoral soft tissue lesions. STUDY DESIGN: The study included 160 patients presenting with oral soft tissue lesions classified into 4 categories: autoimmune diseases, mucosal growths, potentially (pre)malignant lesions, and oral cancer. Each lesion was evaluated by means of intraoral UHFUS, through B-mode and C-mode acquisitions of the area of interest. The UHFUS findings were compared with the histopathologic findings. RESULTS: All values for sensitivity, specificity, and negative predictive value exceeded 90%. Sensitivity was perfect (100%) for mucosal growths and oral cancer. Specificity was almost perfect for all 4 categories of lesions, ranging from 97% to 99%. Values for positive predictive value ranged from 83% to 99%. CONCLUSIONS: UHFUS was beneficial in imaging the oral mucosa and the superficial aspects of the underlying soft tissue in detail because of the high spatial resolution of the technique. Consistent patterns were recognized for different categories of lesions. UHFUS holds the promise of being a valuable support to the clinician in terms of diagnosis, treatment, and follow-up of oral lesions.
