Transoral endoscopic thyroidectomy—essentiality of classification

Since the adoption of natural orifice translumenal endoscopic surgery (NOTES) for thyroid surgery via transoral access, its popularity has increased worldwide, especially in Asian countries. The advantage of this innovative surgery is its scar-free result, which is ideal for all kinds of operations. However, care must be taken to classify the transoral endoscopic thyroidectomy approach appropriately because they are completely different in technique and outcome.
