Popis: Introduction. Thyroidectomy creates a potential risk for all parathyroid glands and the recurrent laryngeal nerve (RLN). The identification and dissection of the RLN is the gold standard for preserving its function. In some cases, it may be quite difficult to identify the nerve localization. In such elusive locations, we aimed to identify RLNs using peroperative injection of a blue dye into the inferior thyroid artery.Materials and Methods. This study included 10 selected patients whose RLN identification had been difficult peroperatively during the period from April 2008 to June 2009. When the RLNs became elusive in location, the branches of the inferior thyroid artery (ITA) on the capsule of the thyroid lobe were isolated, and then 0.5 mL isosulphan blue dye was injected into the artery.Results. RLN was carefully dissected in the tracheoesophageal groove. RLN was clearly visualized, in all patients. All RLNs were identified along their course in the dyed surrounding tissue. No RLN palsy was encountered.Conclusion. The injection of blue dye into the ITA branches can be used as an alternate method in case of difficulty in identification of RLNs.
