Abstract

This study aims to investigate the effect of primary surgery on the morbidity of reoperative thyroid surgery. Fifty-seven patients (14 male, 43 female; mean age 41 years; range 21 to 70 years), who underwent reoperative thyroid surgery in our clinic between January 2007 and January 2012 were retrospectively analyzed in terms of vocal cord paralysis, temporary or permanent hypoparathyroidism, and other complications. The patients were classified into two groups. The first group consisted of 42 completion thyroidectomy patients that had undergone the primary operation of unilateral total lobectomy + isthmusectomy in our clinic, whereas the second group consisted of 15 patients that had undergone bilateral subtotal or near total thyroidectomy in another center. Complication rates were compared between the groups. Complication rates were observed as permanent vocal cord paralysis in one patient (1.7%), permanent hypocalcemia in two patients (3.5%) and temporary hypocalcemia in four patients (7%). None of the patients had temporary vocal cord paralysis. The complications in the second group were significantly higher than the first group (p=0.021). The minimal operation should be hemithyroidectomy (total lobectomy and isthmusectomy) to minimize the complications. This approach removes the need for the intervention to the previous surgery field during reoperative thyroid surgery.
