BACKGROUND: Unilateral parathyroid exploration with @entity652 removal and identification of a normal parathyroid gland is a controversial surgical approach to the treatment of @entity459 . The aim of this study was to evaluate the ability of high-resolution ultrasonography to localize @entity652 preoperatively and to assess the effect of such localization on operative time. METHODS: One hundred twenty consecutive previously non-operated @entity1 with @entity459 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 @entity652 . No significant difference was found in the presence of @entity1374 (p =.2). A positive sonographic examination decreased the operative time to an average of 59 minutes. The average size of the @entity652 was 19 mm (range, 4-55 mm). A positive and highly statistically significant correlation was found between @entity652 size and both preoperative @entity460 level (p =.01) and parathyroid hormone level (p =.0001). CONCLUSIONS: In experienced hands, high-resolution ultrasonography can be a cost-effective means of localizing @entity3243 when unilateral neck exploration is considered the acceptable surgical approach.
