Tissue dissection with saline injection: application in thyroid surgery

Postoperative hypoparathyroidism is a thyroidectomy complication. The effect of this complication cannot be accurately quantified. The incidence of hypoparathyroidism after total thyroidectomy has high variability in the literature, between 7 and 37%. Data from 78 patients who underwent total thyroidectomy with Tissue Dissection with Solution Injection (TDSI group) from December 2018 to August 2019 were retrospectively reviewed. These patients were compared with 78 patients to whom the technique was not applied (non-TDSI group), and they were treated from January 2018 to September 2018. All thyroidectomies were performed by the same surgeon. The mean duration of a thyroidectomy was 1 hour. The reduction of the incidence of postoperative hypoparathyroidism in the group of patients was applied in respect of the technique of tissue dissection with saline injection. TDSI technique paves the way for further application to other tissues and surgeries.
