The problem of recurrent thyroglossal duct remnants

Area of Science:

• Pediatric Surgery
• Surgical Oncology

Background:

• Thyroglossal duct cysts and sinuses are common pediatric surgical conditions.
• Standard surgical practice involves removing the duct remnant down to and including the middle third of the hyoid bone.

Purpose of the Study:

• To evaluate the effectiveness of standard surgical techniques for thyroglossal duct remnants.
• To identify optimal surgical strategies for recurrent thyroglossal duct cysts and sinuses.

Main Methods:

• Retrospective review of 270 pediatric cases of thyroglossal duct cysts and sinuses operated on by experienced pediatric surgeons.
• Analysis of recurrence patterns and outcomes based on surgical techniques employed.

Main Results:

• Twenty-seven recurrences (10%) were observed, with three cases among the authors' patients.
• Most recurrences were associated with the persistence of the middle third of the hyoid bone; its removal led to cure.
• A subset of patients experienced recurrence despite the standard procedure, necessitating deeper or wider excisions to address residual tracts or laterally deviated respiratory epithelial remnants.

Conclusions:

• While standard thyroglossal duct remnant excision is often effective, persistent middle third of the hyoid bone is a key factor in recurrence.
• For refractory cases, extended surgical approaches including deeper or wider excisions are crucial for successful treatment.
• Lateral deviations of respiratory epithelium, potentially representing branchial cleft sinuses, should be considered in complex recurrent cases.
