Abstract
This review is aiming to discuss the complication of thyroid surgery. The present review was conducted by searching in Medline, Embase, and Web of Science, Science Direct, BMJ journal and Google Scholar for, researches, review articles and reports, published over the past years. Books published on complication of thyroid surgery. If several studies had similar findings, we randomly selected one or two to avoid repetitive results. On the basis of findings and results this review found the new ranking system significantly correlated with complexity of surgery (P < 0.0001) as well as with the length of the hospital stay (P < 0.0001). The average incidence of temporary RLNP after thyroid operations is 9.8% and the incidence of permanent RLNP is 2.3%. There was no significant increased risk of permanent hypocalcemia or temporary or permanent vocal cord palsy when a central neck dissection was performed in addition to a thyroidectomy. After thyroidectomy, re-bleeding occurred in 2.1% and was associated with older age and male gender. Postoperative infection occurred in 1.6% and associated with lymph node operation. Postoperative unilateral paresis of the recurrent laryngeal nerve was diagnosed 3.9% and bilateral paresis in 0.2%.
