Summary
Complete removal of thyroglossal duct cysts (TGDC) and their tracts is achievable while preserving the hyoid bone. This surgical approach for TGDC and dermoid cysts shows no recurrence and minimal complications.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Surgical Oncology
Background:
- Thyroglossal duct cysts (TGDC) are common congenital neck masses.
- Complete excision, including the tract to the base of the tongue, is crucial to prevent recurrence.
- Hyoid bone removal is sometimes necessary but may impact postoperative function.
Purpose of the Study:
- To evaluate the feasibility and outcomes of complete TGDC and tract excision while preserving the hyoid bone.
- To assess the rate of recurrence and complications associated with this surgical technique.
- To identify potential impacts of hyoid bone preservation on swallowing and the retroglossal space.
Main Methods:
- A prospective cohort study involving 21 patients diagnosed with TGDC or fistula.
- Surgical management included dissection and removal of the TGDC and its tract(s) to the tongue base, prioritizing hyoid bone preservation.
- Histopathological examination confirmed diagnoses, with 16 cases of TGDC and 5 of dermoid cyst.
Main Results:
- Complete excision of TGDC and tracts was achieved in all patients.
- The hyoid bone was preserved in 19 out of 21 patients; partial resection was needed in two cases.
- No recurrence was observed, and complications were minimal.
- Multiple tracts were successfully dissected and removed in three cases with hyoid bone preservation.
Conclusions:
- Complete surgical removal of TGDC and associated tracts is feasible with a high rate of hyoid bone preservation.
- This approach leads to no recurrence and minimal complications.
- Further research is needed to study the long-term effects of hyoid bone preservation on swallowing and the retroglossal space.

01:23The Thyroid Gland
9.1K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:12The Hyoid Bone
6.9K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
