Exploration of the neck for hyperparathyroidism

Area of Science:

• Endocrinology
• Surgical Oncology
• Anatomy

Background:

• Hyperparathyroidism diagnosis and management require precise surgical localization of abnormal parathyroid glands.
• Previous neck dissections can complicate reoperative surgery for persistent or recurrent hyperparathyroidism.

Purpose of the Study:

• To present a refined, step-by-step surgical exploration protocol for hyperparathyroidism.
• To highlight the utility of selective venous catheterization and parathormone immunoassay in preoperative localization.

Main Methods:

• A 15-year retrospective review of 148 patients undergoing neck exploration for hyperparathyroidism.
• Utilized selective catheterization of neck veins with parathormone immunoassay for preoperative localization.
• Emphasized anatomical knowledge, meticulous surgical dissection, and intraoperative gland identification techniques, including the "angle of identification".

Main Results:

• Selective catheterization proved valuable for preoperative localization, especially in patients with prior neck surgery.
• Successful exploration depended on detailed anatomical understanding and careful surgical technique.
• Grossly abnormal glands were excised, while remaining glands were biopsied and examined by a pathologist using frozen-section techniques.

Conclusions:

• A systematic approach combining anatomical knowledge, advanced localization techniques, and expert pathology enhances surgical success rates for hyperparathyroidism.
• The described protocol offers a reliable strategy for both initial and reoperative parathyroid exploration.
