THYROID TUMORS, TUMOR
All patients received a standard ultrasound evaluation before surgery utilizing Philips Q5 or Philips iU22 ultrasound equipment (both Health care, Eindhoven, the Netherlands). Modestly tilting the patient's head while they were lying supine was ideal. This allowed for a thorough assessment of the thyroid and cervical region via longitudinal, horizontal, and continuous scanning using ultrasonography. Ultrasound was used to observe the size of thyroid tumors (longest axis of nodules), tumor location (left lobe, right lobe, or isthmus), tumor location (upper, middle, and lower pole), internal echo pattern (uniform, uneven, or uneven), tumor boundary (clear, hazy, or blurred), and tumor calcification.
