BACKGROUND: Unilateral parathyroid exploration with adenoma removal and identification of a normal parathyroid gland is a controversial surgical approach to the treatment of primary hyperparathyroidism. The aim of this study was to evaluate the ability of high-resolution ultrasonography to localize adenomas preoperatively and to assess the effect of such localization on operative time. METHODS: One hundred twenty consecutive previously non-operated patients with primary hyperparathyroidism underwent ultrasonography before surgery, which consisted of unilateral neck exploration. The procedure was changed to bilateral exploration when justified by the surgical findings. RESULTS: The sensitivity and positive predictive value of the ultrasonographic examinations were 89% and 98%, respectively. These results were obtained regardless of the size of the adenoma. No significant difference was found in the presence of thyroid multinodular disease (p =.2). A positive sonographic examination decreased the operative time to an average of 59 minutes. The average size of the adenomas was 19 mm (range, 4-55 mm). A positive and highly statistically significant correlation was found between adenoma size and both preoperative calcium level (p =.01) and parathyroid hormone level (p =.0001). CONCLUSIONS: In experienced hands, high-resolution ultrasonography can be a cost-effective means of localizing parathyroid adenomas when unilateral neck exploration is considered the acceptable surgical approach.
