title: Endoscope-assisted intra-oral resection of the external thyroglossal duct cyst.
abstract: OBJECTIVE
  Surgical removal of a thyroglossal duct cyst (TGDC) and its tract is usually accomplished through an external neck incision, including the removal of the middle part of hyoid bone and a block of tissues extending to the foramen cecum. However, this procedure inevitably results in neck scarring. We implemented a modified approach to TGDC removal in a 28-year-old woman through the floor of the mouth using an endoscope system.
  
  
  METHODS
  Here, we describe the detailed procedure of the endoscope-assisted intra-oral resection for TGDC. The total operative time was 130 minutes. The patient complained of swelling and pain in the floor of the mouth for 2 days, but did not require any intervention. Follow-up imaging studies confirmed no recurrence (18 months) without any sequelae, and the patient was satisfied with her surgical outcome.
  
  
  CONCLUSIONS
  The intra-oral approach through the floor of the mouth is a technically feasible alternative surgical option that allows for complete removal of a TGDC without the neck scar.
