Minimally invasive procedure for resection of a parathyroid adenoma: the role of preoperative high-resolution ultrasonography.

Purpose: Solitary adenoma of the parathyroid is the major cause of primary hyperparathyroidism. Many centers advocate a minimally invasive surgical approach, wherein the surgeon explores only a localized area of the neck according to the preoperative imaging evaluation, and the adenoma is resected without histological sampling from the other parathyroid glands. The aim of this study was to evaluate the ability of high-resolution ultrasonography (US) to localize adenomas preoperatively and thereby aid in patient selection for minimal procedures.

Basaloid squamous carcinoma of the larynx.
