The surgeons take care to identify the facial nerve, the nerve that controls the face, and trace out its branches. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for the US were established. We highlight the importance of considering BCAC in the differential diagnosis in salivary gland tumors. First, you will undergo imaging studies, or scans. The age of the patient helps narrow the differential diagnosis, with vascular and congenital lesions being more frequent in the 1st year of life, while solid tumors are more frequent in older children.
