title: Endoscope-assisted transoral removal of a thyroglossal duct cyst using a frenotomy incision: A prospective clinical trial.
abstract: OBJECTIVE
  Endoscope-assisted transoral removal of a thyroglossal duct cyst (TGDC) has been introduced to clinical practice. However, the technical feasibility, efficacy, and safety of this procedure have not been studied. Herein, we conducted a prospective clinical trial to evaluate endoscope-assisted transoral removal of a TGDC.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Thirty patients were included. We performed endoscope-assisted transoral removal of TGDCs and evaluated the clinical results and complications over more than 2 years.
  
  
  RESULTS
  Endoscope-assisted transoral resection was successful in all cases. However, transient morbidity was noted in one patient. The mean operation time was 67.33 ± 17.26 minutes. Surgery was not required for recurrence or revision during a follow-up.
  
  
  CONCLUSIONS
  Endoscope-assisted transoral resection of a TGDC is a potentially safe and effective procedure leading to excellent functional and cosmetic outcomes. Additionally, considering the embryological development of TGDCs, the transoral approach can open a new access route to these cysts.
