CURRENT EVALUATION OF THYROID-NODULES

Thyroid nodules are common and frequently benign. Current evaluation b y fine-needle aspiration (FNA) biopsy is efficacious and cost-effectiv e. Results of FNA series confirm that this procedure is safe, without serious complications, reliable, and relatively easy to perform. Radio isotope scanning and high-resolution ultrasonography are used in speci al circumstances and not as routine diagnostic tests. When FNA biopsy is applied, benign nodules (75%) are followed medically, and suspiciou s (20%) or malignant (5%) nodules are excised surgically. Overall, FNA biopsy of thyroid nodules has improved surgical selection, resulting in a 25% reduction in thyroidectomies for benign nodules.
