Abstract

Background: Reoperative neck surgery is technically more demanding because of the presence of scar tissue and distorted anatomy. We aimed to investigate the magnetic probe-guided excision of nonpalpable neck lesions in patients with previously operated neck compartments.

Methods: This study included 9 patients with recurrent/persistent thyroid carcinoma, recurrent/persistent hyperparathyroidism with previously operated neck compartments. The pathologic lesions were localized by ultrasonography, and magnetic tracer (0.2 mL, iron oxide) was injected directly into the pathologic lesions. Careful dissection was carried out following the area of maximum magnetic activity until the nonpalpable lesions were identified and excised.

Result: All neck lesions were removed in 9 patients. The median count from lesion was significantly higher than values from lesion bed (background activity; (9900/5 seconds vs 250/5 seconds, P < .001). During follow-up, all patients had negative ultrasonography.

Conclusion: Magnetic probe-guided technique could provide access to nonpalpable lesion localization in centers without readily available access to nuclear medicine facilities.

Keywords: magnetic probe–guided excision; metastatic lymph nodes; papillary thyroid cancer; reoperation.
