The first 60 cases constitute the early stage of the learning curve for endoscopic thyroidectomy. The proficiency and stability of the operation reach the advanced level after 150 cases.
Compared with the lateral approach, the medial approach has the advantages of shorter operative time and possibly lower conversion rate; it also can be as safe as the lateral approach. Whether the MA has less blood loss and lower hospitalization costs remains to be confirmed, and its oncological safety and long-term prognosis are not clear. Due to insufficient data from a limited number of studies, inadequate assessment of the results may arise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
