A systematic review and meta-analysis: surgical outcomes comparing transoral robotic and open approaches to thyroidectomy
摘要
Thyroid cancer incidence is rising, especially in young women. Conventional open thyroidectomy (OT) is effective but leaves a neck scar, affecting mental health. Transoral robotic thyroidectomy (TORT) offers scarless surgery, but its safety and completeness need evaluation. We systematically searched PubMed, Embase, Cochrane Library, and Web of Science for trials comparing TORT and OT. Outcomes included lymph node yield, complications (recurrent laryngeal nerve injury, hypoparathyroidism, hematoma, seroma, flap perforation), operation time, hospital stay, and postoperative pain. A random-effects model was used. Five observational studies were included. TORT had longer operative time, hospital stay, and early postoperative pain than OT. Central lymph node yield, nerve injury, and hypoparathyroidism rates were similar. Flap perforation occurred only in TORT. TORT provides superior cosmesis without compromising oncologic completeness or increasing nerve/parathyroid damage, but at the cost of longer operative time, hospital stay, pain, and risk of flap perforation. Long-term outcomes need further study.
