Background:
Patients undergoing central neck surgery are at risk for hypoparathyroidism. We hypothesized that gamma probe identification of sestamibi-labeled parathyroid glands might help maximize parathyroid preservation.
Methods:
Records of 351 patients who underwent central neck surgery were reviewed. A subgroup of patients underwent sestamibi injection followed by gamma probe-directed parathyroid gland identification.
Results:
Operation was performed for malignancy in 73% of patients and represented a reoperation in 34%. Persistent hypoparathyroidism was more common in patients who underwent reoperation versus a primary operation (6.8% versus 1.7%; P = 0.02). Thirteen patients underwent gamma probe-directed identification of sestamibi-labeled parathyroid glands; in 6 of these patients, sestamibi-labeled parathyroid glands were salvaged from the resected specimens and autografted. None of these 13 patients developed persistent hypoparathyroidism.
Conclusions:
Patients undergoing reoperative central neck surgery are at increased risk for postoperative hypoparathyroidism. Gamma probe-directed salvage of sestamibi-labeled parathyroid glands may help maximize parathyroid preservation, especially in complex or reoperative central neck surgery.
