Diagnostic Tools Before Thyroidectomy: A Surgical Perspective

Before performing a thyroidectomy, a range of diagnostic studies is typically conducted to evaluate thyroid function and structure. Ultrasound and elastography are employed to assess the gland’s morphology and to identify nodular goiters that may necessitate fine-needle aspiration cytology (FNAC) or surgical intervention. Cervical adenopathies in patients suspected of thyroid malignancy are also evaluated via ultrasound. FNAC is the most effective diagnostic tool for suspicious thyroid nodules. Computed tomography (CT) is invaluable in assessing the relationship between large goiters and surrounding structures or identifying deep lymph node metastases in thyroid carcinomas. This article discusses the essential preoperative investigations required for thyroidectomy and their impact on surgical decision-making.
