Abstract:Objective:To analyze the clinical significance of modified thyroidectomy by trans-isthmus approach.
Methods :The clinical data of 5 751 patients who underwent thyroidectomy from Jan.1996 to Jan.2006 were retrospectively analyzed. All cases were divided into two groups. The modified operation group (n=3288) was treated by trans-isthmus thyroidectomy. Another group (n=2463) was treated by routine approach. The operation time, bleeding volume, and complications were observed and compared.
Results:In modified operation group, the mean operation time, bleeding volume, temporary injury of recurrent laryngeal nerve, tracheal discomfort, and hypocalcemia were significantly decreased than those in routine approach group (P<0.01). The patients in the modified operation group tolerated the operation better as compared to the routine approach group. There was no statistical difference in postoperative bleeding between the two groups.
Conclusions:The modified thyroidectomy by trans-isthmus approach could obviously decrease the operation time, bleeding volume, and rate of injury of recurrent laryngeal nerve and hypocalcemia.
