PURPOSE: Surgical excision is the definitive treatment for localized recurrence of @entity3557 . Reoperation for recurrence, however, is challenging and associated with increased operative times and complication rates. For safe and effective reoperation, ultrasound-guided charcoal tattooing localization can be used. The aim of this study was to investigate the feasibility and safety of the ultrasound-guided charcoal tattooing localization. METHODS: Between November 2012 and August 2013, ten @entity1 underwent preoperative charcoal tattooing localization for twelve recurrent lesions. @entity1 demographics, pathologic features, and operation results were reviewed. RESULTS: The technical success rate of charcoal tattooing was 100%. Eight @entity1 had one recurrent lesion, and two @entity1 had double lesions. Among these 12 recurrent lesions, three (25%) were found in level II, four (33%) in level IV, four (33%) in level VI, and one (8%) was found in the thyroidectomy bed site. The mean size of lesions was 0.87    0.35 cm. Of these 10 @entity1 , eight @entity1 underwent selective lymph node dissection, one @entity1 underwent modified radical neck dissection, and one @entity1 underwent recurrent mass excision. Transient @entity3747 developed in one @entity1 , and no recurrent @entity3746 occurred. There were no major complications related to the injection of the charcoal. The mean follow-up period after reoperation was 8.6    2.7 months; in the follow-up ultrasound, there were no remnant lesions in all @entity1 . CONCLUSION: Preoperative ultrasound-guided charcoal tattooing localization for recurrent @entity259 appears to be a feasible and safe procedure for reoperation. Further evaluation is warranted in larger @entity1 ' cohorts.
