Summary

Preoperative ultrasound largely underestimates thyroid gland volume compared to actual surgical measurements. While less accurate for most thyroid conditions, ultrasound shows greater reliability in diffuse toxic goiter (DTG) cases.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Medical Imaging

Background:

  • Accurate preoperative thyroid volume estimation is crucial for surgical planning.
  • Ultrasonography is commonly used to estimate thyroid volume before surgery.

Purpose of the Study:

  • To prospectively compare estimated thyroid volume (EV) via ultrasonography with the actual measured volume (MV) of excised thyroid glands.
  • To assess the reliability of preoperative ultrasound in estimating thyroid volume across different thyroid pathologies.

Main Methods:

  • A prospective study involving 101 patients undergoing total thyroidectomy.
  • Comparison of preoperative ultrasound-estimated thyroid volume (EV) with postoperative measured volume (MV) of the resected gland.
  • Analysis of discrepancies based on thyroid morphology and indications for surgery (multinodular goiter, diffuse toxic goiter (DTG), uninodular disease).

Main Results:

  • Ultrasonography significantly underestimated thyroid volume in 89 out of 101 patients.
  • Mean EV (28.3 mL) was significantly lower than mean MV (36.2 mL) (p < 0.0001).
  • Ultrasound estimation was found to be more reliable in patients with DTG compared to other thyroid conditions.

Conclusions:

  • Preoperative ultrasonography is not a reliable method for accurately estimating thyroid gland volume due to consistent underestimation.
  • Despite limitations, ultrasound demonstrates higher reliability in assessing thyroid volume for DTG patients.
  • Further research with larger cohorts may help refine mathematical models for improved thyroid volume estimation.
