Thyroglossal Duct Cyst · Sistrunk Procedure

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Infection? + confirm normal thyroid
   Acute infection? Is an orthotopic thyroid confirmed?
   • No acute infection, imaging confirms an orthotopic thyroid → → Sistrunk procedure
   • Acute infection/abscess → Acute infection → control first, then Sistrunk
   • Suspected ectopic thyroid (only thyroid tissue)/suspected malignancy → Exclude ectopic/malignancy → evaluate
2. [End] → Sistrunk procedure
   Thyroglossal duct cyst (orthotopic thyroid confirmed) → Sistrunk procedure (excise cyst + mid-portion of the hyoid + tract to the foramen cecum), lowest recurrence; simple cyst excision has a high recurrence rate.
3. [End] Acute infection → control first, then Sistrunk
   Acute infection/abscess → antibiotics ± incision and drainage to control inflammation first, then Sistrunk after it settles (surgery during infection has high recurrence and complications).
4. [End] Exclude ectopic/malignancy → evaluate
   Preoperative ultrasound (nuclear scan if needed) to confirm an orthotopic thyroid (avoid removing the only ectopic thyroid and causing hypothyroidism); suspicious nodule/malignancy (papillary carcinoma) → cytology evaluation then management.
