Summary

This study aims to create a simple tool that helps doctors predict how difficult a specific type of thyroid cancer surgery (called transoral and submental thyroidectomy) will be. Researchers will study 500 patients to find out which factors before surgery make the operation harder. The goal is to help surgeons plan better and reduce risks like nerve injury or long surgery times.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients with FNA proven differentiated thyroid cancer, were willing to undergo total thyroidectomy and central lymph node dissection via transoral and submental approach. Patients were well informed about the transoral and submental approach and were aware of the potential benefits and risks. Patient consented for us to use perioperative data.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)
