UNILATERAL PARATHYROIDECTOMY - THE VALUE OF THE LOCALIZING SCAN

Surgery for correction of primary hyperparathyroidism utilizing a stan dard bilateral neck exploration has a success rate of approximately 90 to 95%. With the inception of pre-operative localization studies that were 90% accurate in localizing the diseased gland, the concept arose that a unilateral exploration could be as successful as a bilateral e xploration. Bilateral exploration of the neck for hyperparathyroidism exposes the patient to a greater potential of morbidity for hypoparath yroidism and recurrent laryngeal nerve injury. It is our feeling based on personal experience that unilateral parathyroidectomy in selective cases can be as successful as the bilateral operation and be more cos t effective, saving over $1,100 (U.S.) per case.
